I want to make my activity full screen with status bar on top of it  like this picture:

[![enter image description here][1]][1]


I have used this code in `manifest` inside `activity` tag:

    &#39;android:theme=&quot;@style/Theme.AppCompat.Light.NoActionBar&quot;&#39;

But my view doesn&#39;t start from the status bar &amp; it looks like this:

How can I make my `activity` look like the first one?

Android - Making activity full screen with status bar on top of it

Details:

I&#39;m extending ActionBarActivity.  
Eclipse and SDK fully patched as of 2011-11-06.  

    &lt;uses-sdk android:minSdkVersion=&quot;4&quot; android:targetSdkVersion=&quot;14&quot; /&gt;  
Deployed to Samsung device with Android 2.3.3  
Application has `android:theme=&quot;@android:style/Theme.Light&quot;`  

**Issue:** application is light, but ActionBar is blue with grey icons, hardly visible against the blue background color. I also want the ActionBar to be light, so they grey icons are more visible.

I&#39;ve tried modifying the styles but to no avail.  
I&#39;m probably missing something trivial.

I&#39;m creating a Dialog Box on Holo Theme and want to follow the OS default way of displaying the buttons. So far I have created the dialog box but the buttons don&#39;t render in the way it does in the apps done in Holo for ICS.
How can I do this?

How to Android Holo Theme style dialog box buttons

Consider this:

**styles.xml**

    &lt;style name=&quot;BlueTheme&quot; parent=&quot;@android:style/Theme.Black.NoTitleBar&quot;&gt;
        &lt;item name=&quot;theme_color&quot;&gt;@color/theme_color_blue&lt;/item&gt;
    &lt;/style&gt;

**attrs.xml**

    &lt;attr name=&quot;theme_color&quot; format=&quot;reference&quot; /&gt;

**color.xml**

    &lt;color name=&quot;theme_color_blue&quot;&gt;#ff0071d3&lt;/color&gt;

So the **theme color** is referenced by the theme. How can I get the theme_color (reference) programmatically? Normally I would use `getResources().getColor()` but not in this case because it&#39;s referenced!



Get color value programmatically when it&#39;s a reference (theme)

I am going to give an example to demonstrate the greater point.

Imagine my app has a number of FloatingActionButtons. Consequently, I want to create one style and reuse it. So I do the following:


    &lt;style name=&quot;FabStyle” parent =&quot;Widget.Design.FloatingActionButton&quot;&gt;
        &lt;item name=&quot;android:layout_width&quot;&gt;wrap_content&lt;/item&gt;
        &lt;item name=&quot;android:layout_height&quot;&gt;wrap_content&lt;/item&gt;
        &lt;item name=&quot;android:layout_margin&quot;&gt;16dp&lt;/item&gt;
        &lt;item name=&quot;app:backgroundTint&quot;&gt;@color/accent&lt;/item&gt;
        &lt;item name=&quot;app:layout_anchorGravity&quot;&gt;end|bottom&lt;/item&gt;
    &lt;/style&gt;

The problem I am having is that the code is not compiling because it is complaining about

    Error:(40, 5) No resource found that matches the given name: attr &#39;app:backgroundTint&#39;.

I tried bringing the namespace in through the `resources` tag but that is not working

    &lt;resources
        xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;
        xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        &gt;

Any ideas how I might get this to work?

I&#39;m trying to set the theme for a fragment. 

Setting the theme in the manifest does not work:

From looking at previous blogs, it appears as though I have to use a ContextThemeWrapper. Can anyone refer me to a coded example? I can&#39;t find anything.

The switch widget introduced in API 14 is styled by default with holo theme.
I want to style it slightly different, changing its colors and shape a bit for branding reasons. How does one go about this? I know it must be possible, as ive seen the difference between default ICS and Samsung&#39;s touchwiz theme 

![enter image description here][1]

I assume I&#39;ll need some state drawables, and I&#39;ve seen a few styles in http://developer.android.com/reference/android/R.styleable.html with Switch_thumb and Switch_track that look like what I might be after. I just don&#39;t know how to go about using them.

I&#39;m using ActionbarSherlock if that makes a difference. Only devices running API v14 or above will be able to use a switch at all, of course.

How can I style an Android Switch?

I referred this [link][1]. In that if the user clicks on EditText(for ex To: ) at that time  keyboard will be popped out and at the same time the user can be able to scroll to see all remaining views(ex: compose,subject, send button) in that screen. Similarly in my app I have one activity in that I am having some widgets or views.
    Suppose if the user clicks on Edittext which is in my Activity then keyboard is popping out and i can be able to scroll to see remaining views. But if i give this attribute `android:theme=&quot;@android:style/Theme.NoTitleBar.Fullscreen&quot;` in manifest i was unable to scroll to see remaining views but if give attribute `android:theme=&quot;@android:style/Theme.NoTitleBar&quot;` like this in manifest I can be able to scroll to see remaining view but there is status bar in that screen, here I want full screen and even if the keyboard is popped out I can scroll to see remaining views..? what changes I have to made for this..?

How to hide status bar in Android

I&#39;m trying to modify the default background theme color, which should be easy but surprisingly I can&#39;t get it working. Please note that I want the change to be across the entire app, not just for a single activity. Here is my code: 

styles.xml

    &lt;resources&gt;

        &lt;color name=&quot;white_opaque&quot;&gt;#FFFFFFFF&lt;/color&gt;
        &lt;color name=&quot;pitch_black&quot;&gt;#FF000000&lt;/color&gt;

        &lt;style name=&quot;AppTheme&quot; parent=&quot;android:Theme.Light&quot;&gt;
            &lt;item name=&quot;android:background&quot;&gt;@color/white_opaque&lt;/item&gt;
            &lt;item name=&quot;android:windowBackground&quot;&gt;@color/white_opaque&lt;/item&gt;
            &lt;item name=&quot;android:colorBackground&quot;&gt;@color/white_opaque&lt;/item&gt;
        &lt;/style&gt;

    &lt;/resources&gt;



and of course in the manifest

    &lt;application
        .
        .
        .
        android:theme=&quot;@style/AppTheme&quot; &gt; 
    &lt;/application&gt;

Android doc which I consulted on modifying themes:
http://developer.android.com/guide/topics/ui/themes.html

I&#39;ve tried switching between white_opaque and pitch_black for all the xml attributes but it doesn&#39;t change a thing. Any suggestions?

Setting Android Theme background color

There are the following Theme.AppCompat classes:

    Theme.AppCompat
    Theme.AppCompat.Light
    Theme.AppCompat.Light.DarkActionBar
    Theme.AppCompat.NoActionBar
    Theme.AppCompat.Light.NoActionBar
    Theme.AppCompat.DialogWhenLarge
    Theme.AppCompat.Light.DialogWhenLarge
    Theme.AppCompat.Dialog
    Theme.AppCompat.Light.Dialog
    Theme.AppCompat.CompactMenu

and the following ThemeOverlay.AppCompat classes:

    ThemeOverlay.AppCompat
    ThemeOverlay.AppCompat.Light
    ThemeOverlay.AppCompat.Dark
    ThemeOverlay.AppCompat.ActionBar
    ThemeOverlay.AppCompat.Dark.ActionBar

Why would one use ThemeOverlay.AppCompat.light vs Theme.AppCompat.Light for example? I see that there are much less attributes defined for ThemeOverlay --  I am curious what the intended use case for ThemeOverlay is.

When should one use Theme.AppCompat vs ThemeOverlay.AppCompat?

I am trying to use the following code to center the text in the `ActionBar`, but it aligns itself to the left. 

How do you make it appear in the center?

   

    ActionBar actionBar = getActionBar();
    actionBar.setDisplayShowTitleEnabled(true);
    actionBar.setTitle(&quot;Canteen Home&quot;);
    actionBar.setHomeButtonEnabled(true);
    actionBar.setIcon(R.drawable.back);

How to center align the ActionBar title in Android?

I&#39;m trying to recreate the look of `Theme.AppCompat.Light.DarkActionBar` with the new support library Toolbar. 

If I choose `Theme.AppCompat.Light` my toolbar will be light and if I choose `Theme.AppCompat` it will be dark. (Technically you have to use the `.NoActionBar` version but as far as I can tell the only difference is

    &lt;style name=&quot;Theme.AppCompat.NoActionBar&quot;&gt;
        &lt;item name=&quot;windowActionBar&quot;&gt;false&lt;/item&gt;
        &lt;item name=&quot;android:windowNoTitle&quot;&gt;true&lt;/item&gt;
    &lt;/style&gt;

Now there&#39;s no `Theme.AppCompat.Light.DarkActionBar` but naively I thought it&#39;d be good enough to just make my own

    &lt;style name=&quot;Theme.AppCompat.Light.DarkActionBar.NoActionBar&quot;&gt;
        &lt;item name=&quot;windowActionBar&quot;&gt;false&lt;/item&gt;
        &lt;item name=&quot;android:windowNoTitle&quot;&gt;true&lt;/item&gt;
    &lt;/style&gt;

However with this my toolbars are still `Light` themed. I&#39;ve spent hours now trying different combinations of mixing the Dark (base) theme and the Light theme but I just can&#39;t find a combination that will let me have light backgrounds on everything but the toolbars.

Is there a way of getting the `AppCompat.Light.DarkActionBar` look with import `android.support.v7.widget.Toolbar`&#39;s?


How do I style appcompat-v7 Toolbar like Theme.AppCompat.Light.DarkActionBar?

I want to have 2 selectable themes for my application. In order to do that, I defined some attributes, like this:
 
     &lt;attr format=&quot;color&quot; name=&quot;item_background&quot; /&gt;

Then, I created both themes, like this:

      &lt;style name=&quot;ThemeA&quot;&gt;
         &lt;item name=&quot;item_background&quot;&gt;#123456&lt;/item&gt;
     &lt;/style&gt;
    
     &lt;style name=&quot;ThemeB&quot;&gt;
         &lt;item name=&quot;item_background&quot;&gt;#ABCDEF&lt;/item&gt;
     &lt;/style&gt;


This method works great, allowing me to create and modify several themes easily. The problem is that **it seems that it can be used only in Views, and not in Drawables**.

For example, referencing a value from a View inside a layout works:

     &lt;TextView android:background=&quot;?item_background&quot; /&gt;

But doing the same in a Drawable doesn&#39;t:

     &lt;shape android:shape=&quot;rectangle&quot;&gt;
         &lt;solid android:color=&quot;?item_background&quot; /&gt;
     &lt;/shape&gt;

I get this error when running the application:

        java.lang.UnsupportedOperationException: Can&#39;t convert to color: type=0x2

If instead of `?item_background` I use a hardcoded color, it works, but that doesn&#39;t allow me to use my themes. I also tried `?attr:item_background`, but the same happens.

How could I do this? And why does it work in Views but not in Drawables? I can&#39;t find this limitation anywhere in [the documentation](http://developer.android.com/guide/topics/resources/accessing-resources.html#ReferencesToThemeAttributes)...

How to reference style attributes from a drawable?

UnsupportedOperationException: Can&#39;t convert to dimension: type=0x1

I am looking at the Honeycomb Gallery sample code ([here][1]) and I ran across the following code while trying to add action items in my own app:

    &lt;item android:id=&quot;@+id/camera&quot;
        android:title=&quot;Camera&quot;
        android:icon=&quot;?attr/menuIconCamera&quot;
        android:showAsAction=&quot;ifRoom&quot; /&gt;

The `?attr` is throwing me for a loop.  Can someone please explain what this is doing?  How is this related to a drawable?  I can&#39;t seem to find any good information on Google.  Also is there a listing or gallery of attributes we can use for icons instead of just `menuIconCamera`?

Thanks

Edit:
I did some more looking around and found that attrs.xml looks like this:

    &lt;resources&gt;
    &lt;declare-styleable name=&quot;AppTheme&quot;&gt;
        &lt;attr name=&quot;listDragShadowBackground&quot; format=&quot;reference&quot; /&gt;
        &lt;attr name=&quot;menuIconCamera&quot; format=&quot;reference&quot; /&gt;
        &lt;attr name=&quot;menuIconToggle&quot; format=&quot;reference&quot; /&gt;
        &lt;attr name=&quot;menuIconShare&quot; format=&quot;reference&quot; /&gt;
    &lt;/declare-styleable&gt;
&lt;/resources&gt;

Unfortunately that just makes it even more confusing for me.  What is this doing?

I&#39;ve written a custom widget for a control that we use widely throughout our application.  The widget class derives from `ImageButton` and extends it in a couple of simple ways. I&#39;ve defined a style which I can apply to the widget as it&#39;s used, but I&#39;d prefer to set this up through a theme.  In `R.styleable` I see widget style attributes like `imageButtonStyle` and `textViewStyle`.  Is there any way to create something like that for the custom widget I wrote?

How to: Define theme (style) item for custom widget

I&#39;m creating an Android app and I&#39;m using the AndroidX libraries and Material design theme. My app theme on `styles.xml` is:

    &lt;style name=&quot;AppTheme&quot; parent=&quot;Theme.MaterialComponents.Light.DarkActionBar&quot;&gt;
        &lt;item name=&quot;colorPrimary&quot;&gt;@color/colorPrimary&lt;/item&gt;
        &lt;item name=&quot;colorPrimaryDark&quot;&gt;@color/colorPrimaryDark&lt;/item&gt;
        &lt;item name=&quot;colorAccent&quot;&gt;@color/colorAccent&lt;/item&gt;
    &lt;/style&gt;

I have the following FAB from a custom library:

    &lt;com.leinardi.android.speeddial.SpeedDialView
            android:id=&quot;@+id/work_log_fab&quot;
            android:layout_width=&quot;wrap_content&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:layout_gravity=&quot;bottom|end&quot;
            app:layout_behavior=&quot;@string/speeddial_scrolling_view_snackbar_behavior&quot;
            app:sdMainFabClosedSrc=&quot;@drawable/ic_add_white_24dp&quot;
            app:sdOverlayLayout=&quot;@id/overlay&quot; /&gt;

And also tried the default FAB:

    &lt;com.google.android.material.floatingactionbutton.FloatingActionButton
            android:id=&quot;@+id/fab&quot;
            android:layout_width=&quot;wrap_content&quot;
            android:layout_height=&quot;wrap_content&quot;
            android:layout_gravity=&quot;end|bottom&quot;
            android:src=&quot;@drawable/ic_add_white_24dp&quot;
            android:layout_margin=&quot;16dp&quot; /&gt;

No mater the color of the icon (a vector drawable), the icon inside the FAB (from the library and from the default) is always black. I have narrowed down the problem to the material design theme, since using the old `Theme.AppCompat.Light.DarkActionBar` instead of the new `Theme.MaterialComponents.Light.DarkActionBar` the icon inside the FAB gets the color of the original vector drawable.

Does anyone know why this is happening and how to solve it?

I&#39;m trying to figure out the right way to use a custom font for the toolbar title, and center it in the toolbar (client requirement).

At the moment, i&#39;m using the good old ActionBar, and I was setting the title to empty value, and using `setCustomView` to put my custom font TextView and center it using ActionBar.LayoutParams.

Is there a better way to do that? Using the new Toolbar as my ActionBar.

I&#39;d like to use the `Holo.Light` theme on devices that support it, and fall back to the regular `Light` theme on other devices.

I&#39;m looking for things like list backgrounds, primary and secondary text, ActionBar, etc.

Google gives some examples at the [Themes](http://developer.android.com/design/style/themes.html) and [Color](http://developer.android.com/design/style/color.html) style guidelines, but they don&#39;t really go into the actual color values being used. I can grab them from the images, but I’d rather use something a little more accurate.

But when I want to search anything then I need to go to browser which is very bright.

How to change the background color of Action Bar&#39;s Option Menu in Android 4.2?

May I know what is the difference between `styles.xml` and `themes.xml`? To me, they just look same as both XML are in the same format.

    &lt;style name=&quot;...
        &lt;item name=&quot;...

So, in my app which provide customization coloring, size, drawable, ... do I need both `styles.xml` and `themes.xml` as well? How should I decide which XML to put in which file?

What is difference among styles.xml and themes.xml

I&#39;m using AppCompat and my theme is extending `Theme.AppCompat.Light.DarkActionBar`.
 
When in Android 5 Lollipop and I press the recent apps button, my app appears with a **dark** title instead of a white title in the ActionBar.

When I&#39;m inside the app everything looks fine. 

What can I do to change the title color in the recent apps view? 

**EDIT**: just figured out that if I use a darker `colorPrimary`, the title becomes white. I still need a way to force the white title with the original color.

Android 5.0: how to change recent apps title color?

I have made a few apps that support multiple themes, but I always had to restart the app when user switches theme, because `setTheme()` needs to be called before `setContentView()`.

I was okay with it, until I discovered this app. It can seamlessly switch between two themes, and with transitions/animations too!

![enter image description here][1]

Please give me some hints on how this was implemented (and animations too). Thanks!

How to switch themes (night mode) without restarting the activity?

What I&#39;m trying should be quite easy with themes, but I can&#39;t find out how to:
I want all text to be white by default in my app.
I created a custom theme in theme.xml:

    &lt;style name=&quot;Theme&quot; parent=&quot;@android:Theme&quot;&gt;
    &lt;/style&gt;
    
    &lt;style name=&quot;TextAppearance.Theme&quot; parent=&quot;@android:TextAppearance.Theme&quot;&gt;
    	&lt;item name=&quot;android:textColor&quot;&gt;#ffffffff&lt;/item&gt;
    &lt;/style&gt;

and set it for the whole application:

    &lt;application
        android:icon=&quot;@drawable/icon&quot;
        android:label=&quot;@string/app_name&quot;
        android:theme=&quot;@style/Theme&quot;&gt;

But labels are still black.
What&#39;s missing?

PS: How can I additionally define styles for different text sizes, to be applied per widget?
Is something like that correct?

    &lt;style name=&quot;Theme.smallText&quot;&gt;
        &lt;item name=&quot;android:textSize&quot;&gt;12dp&lt;/item&gt;
    &lt;/style&gt;

**update**

I took a look at *themes.xml* in Android SDK, it shows how to set the text style for a theme:

    &lt;item name=&quot;textAppearance&quot;&gt;@android:style/TextAppearance&lt;/item&gt;

In my case it should work with this definition:

    &lt;style name=&quot;Theme&quot; parent=&quot;@android:Theme&quot;&gt;
        &lt;item name=&quot;android:textAppearance&quot;&gt;@style/MyText&lt;/item&gt;
    &lt;/style&gt;

    &lt;style name=&quot;MyText&quot; parent=&quot;@android:style/TextAppearance&quot;&gt;
        &lt;item name=&quot;android:textColor&quot;&gt;#ffffffff&lt;/item&gt;
    &lt;/style&gt;

However, it is still not working.

Here&#39;s [another post](http://groups.google.com/group/android-developers/browse_thread/thread/2897ccd0884546b9) about this same issue.

How to change default text color using custom theme?

I am trying to implement the new [ActionBar](http://developer.android.com/guide/topics/ui/actionbar.html) support library that was released by Google a couple days ago.  In the past, I have successfully implemented ActionBarSherlock without any issues using the same method listed on Google Developer&#39;s [Support Library Setup](http://developer.android.com/tools/support-library/setup.html) page - using the guide on how to include the resources (which is similar to how ActionBarSherlock did it). I have the library project loaded in to my own project as a library as well.

I can tell the library is loading fine. When, instead of extending Activity on my MainActivity.java, I changed it to extend ActionBarActivity (as per Google&#39;s instructions), no errors occur - and it imports correctly.

I even tried bypassing the style.xml file and adding `@style/Theme.AppCompat.Light` directly in to the AndroidManifest.xml for both `&lt;application&gt;` and `&lt;activity&gt;` with `android:theme=&quot;@style/ThemeAppCompat.Light&quot;` with all attempts resulting in the same error.

Now the issue is I cannot get it to change the theme, let alone even build without throwing an error.  Below is the error I am receiving, followed by the style.xml file I changed to use the new theme.

I have moderate experience working with Android apps and am running Eclipse with the latest version of the Support Libraries and SDK compiling with API 18 (Android 4.3).

**Error Received During Build**

&gt;error: Error retrieving parent for item: No resource found that matches the given name &#39;@style/Theme.AppCompat.Light&#39;.	styles.xml	/ActBarTest/res/values	line 3	Android AAPT Problem


**style.xml**

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;resources&gt;
        &lt;style name=&quot;Theme.ProsoftStudio.ACTest&quot; parent=&quot;@style/Theme.AppCompat.Light&quot;&gt;
        &lt;/style&gt;
    &lt;/resources&gt;

Any suggestions?  This was never an issue with ActionBarSherlock. I want to work on using this new support library.  It almost seems like the .jar is loading, but not the resources.

Can&#39;t Find Theme.AppCompat.Light for New Android ActionBar Support

A Quote from Google in terms of Designing, and some example of apps:
------------------------------------------------------------------------

Based on what **Google** said in http://developer.android.com/ within design section, a developer should consider three goals:

 - Enchant me
 - Simplify my life
 - Make me amazing

**Which BTW we (Developers) are aware of.** 

By looking at many successful apps on play store, you can see that they are designed by  following Google design guidelines and are pretty much using the *same* **components** and **theming** and **styles** that google used in their own apps.

Many people do enjoy these kind of designs and also these android standards in terms of themes and components, but when you look at some apps in **Playstore** or some hardware manufacturer&#39;s apps like **samsung** whom have built their special apps (like galaxy note 10.1 **note taking app**) or **asus weather app** or in **playstore** the [Timely][1] app which is awesome in terms of functionality and of-course design, you could see they are using different kind of design and components.

-----

Now let&#39;s get deeper in what Google [says][2]:
----------------------------------------------

&gt; A typical Android app uses action bars, and many apps will include a navigation drawer.

Like these:

The Actionbar: ![enter image description here][3]

The Navigation Drawer: 

![enter image description here][4]

And other standard components on android.

But How can some developers make apps so beautiful and functionally perfect (almost! ) like Timely app and not using many of the android typical components defined by google.

---

Lets take a look at **Timely** app:
-----------------------------------

This is the screen where user can see the alarms where he/she could set one or just watch the clock:

![enter image description here][5]
![enter image description here][6]

Now the questions that come in my mind are:

 - How can I theme my app like that?
 - How can I make background animations like that and use it in my apps?
 - Did their developers use unity and eclipse together to make it function as an android app?
 - If they did use unity then how come the app runs very smooth?
 - In its actionbar ,how did they colorized it and defined opacity for the object?
 - What kind of animation class can do what they did in the app? (like the clock time changing animation)
 - If they used unity then how come their app&#39;s size is 10MB?

There are many other apps like this (no 100% that much alike) which have their own special design.

As far as I understand, there aren&#39;t much website that offer custom components for android like http://androidviews.net/ so it seems we are forced to make our own components which is time consuming and in this time (2013) isn&#39;t perfect whereas for ios there are tons of custom components made by other companies.

I also looked at the Timely app website, and within their [FAQ][7] section there is a place where they said they will reveal what and how they did the theming, coloring and components but since there is not time schedule table for their announcement and I don&#39;t like to stay in dark area, I came here to ask you experts.

This is the **quote** from [their website][8]:

&gt; I&#39;m a developer and just can&#39;t figure out how you did those animations
&gt; and color effects.
&gt; 
&gt; We are planning to have an engineering blog in the future. Stay tuned!

If you guys know how to make apps like these or if you know a portion of what kind of animations, components, tricks and hacks they used then you just made my day.

How to make Beautiful &amp; Stylish apps like Timely

I would like to add the support actionbar to one of my activities, I previously had been using the theme.translucent with this activity but in order to make the support actionbar work I needed to inherit the Theme.AppCompat, I need to maintain a translucent theme in this activity but unfortunately there isnt a Theme.AppCompat.translucent that i can see by default, is there any way that this can be done?  

Android how to get AppCompat.Translucent type theme with support actionbar?

I&#39;m a bit confused with these two APIs.

**[ResourcesCompat.getDrawable(Resources res, int id, Resources.Theme theme)][1]**

&gt; Return a drawable object associated with a particular resource ID and styled for the specified theme. Various types of objects will be returned depending on the underlying resource -- for example, a solid color, PNG image, scalable image, etc.
&gt;
&gt; Prior to API level 21, the theme will not be applied and this method simply calls through to getDrawable(int).


**[AppCompatResources.getDrawable(Context context, int resId)][2]**

&gt; Return a drawable object associated with a particular resource ID.
&gt;
&gt; This method supports inflation of **vector** and **animated-vector** resources on devices where platform support is not available.

## Question ##

 1. What is the significant difference between these two classes
    (besides **vector** inflation)?
 2. Which one should I prefer to another and why?

  [1]: https://developer.android.com/reference/android/support/v4/content/res/ResourcesCompat.html#getDrawable(android.content.res.Resources,%20int,%20android.content.res.Resources.Theme)
  [2]: https://developer.android.com/reference/android/support/v7/content/res/AppCompatResources.html#getDrawable(android.content.Context,%20int)

ResourcesCompat.getDrawable() vs AppCompatResources.getDrawable()

I would like to know how can I apply full screen theme ( no title bar + no actionbar ) to an activity. I am using AppCompat library from support package v7. 

I&#39;ve tried to applied `android:theme=&quot;@android:style/Theme.NoTitleBar.Fullscreen&quot;` to my specific activity but it crashed. I think it&#39;s because my application theme is like this.

    &lt;style name=&quot;AppTheme&quot; parent=&quot;Theme.AppCompat.Light.DarkActionBar&quot;&gt;

I also have tried this 

	getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
				WindowManager.LayoutParams.FLAG_FULLSCREEN);

which only hides title bar but not the action bar. 
My current workaround is that hiding the actionbar with 

    getSupportActionBar().hide();

Full Screen Theme for AppCompat

What is the simplest change that I can make to a new Blank Activity, as created by the latest version of Android Studio, to get the app to appear fullscreen?

I want to create a fullscreen Android application. I&#39;m working with Android Studio.
[This post][1] suggests that I add a line such as ...

`android:theme=&quot;@android:style/Theme.Holo.Light.NoActionBar.Fullscreen&quot;`

... to the AndroidManifest.xml file, as shown below:


		&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
		&lt;manifest xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
				package=&quot;com.lexogram.james.blackslate&quot; &gt;

				&lt;application
						android:allowBackup=&quot;true&quot;
						android:icon=&quot;@drawable/ic_launcher&quot;
						android:label=&quot;@string/app_name&quot;
						android:theme=&quot;@style/AppTheme&quot; &gt;
						&lt;activity
								android:name=&quot;com.lexogram.james.blackslate.MainActivity&quot;
								android:label=&quot;@string/app_name&quot;
								android:theme=&quot;@android:style/Theme.Holo.Light.NoActionBar.Fullscreen&quot;&gt;
								&lt;intent-filter&gt;
										&lt;action android:name=&quot;android.intent.action.MAIN&quot; /&gt;

										&lt;category android:name=&quot;android.intent.category.LAUNCHER&quot; /&gt;
								&lt;/intent-filter&gt;
						&lt;/activity&gt;
				&lt;/application&gt;

		&lt;/manifest&gt;

When I do this, the app compiles but it crashes on launch. If I remove the line, the app runs fine, but with the action bar and a title bar, as also noted by other users.

This is my first attempt at creating an Android app, so my app is hardly altered from the original Hello World example.


EDIT:
I created a new project, and made just this one change to it. Here is an extract from the error log:

    FATAL EXCEPTION: main
        java.lang.RuntimeException: Unable to start activity ComponentInfo{com.lexogram.james.test/com.lexogram.james.test.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
            at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2669)...


NOTE: I am testing on a old Samsung SGH-T499Y, running Android 2.2 (Froyo)
