I create programmatically like horizontalview then, how to pass AttributeSet in programmatically.

My constructor looks like this:

    public HorizontalListView(Context context, AttributeSet attrs) {
            super(context, attrs);
        }

I have try this:

    mHlvSimpleList= new HorizontalListView(mcontext,R.style.niceview);

**Error:**

&gt; The constructor HorizontalListView(Context, int) is undefined

in style.xml

    &lt;style name=&quot;niceview&quot;&gt;
        &lt;item name=&quot;android:layout_width&quot;&gt;wrap_content&lt;/item&gt;

How to pass AttributeSet when creating view programmatically in android

I have some difficulties finding the correct way to specify that a progress bar should have the small indefinite style. 

I would be glad if somebody could provide an example for me and others that do a quick search for this information.

How can I change the style of a ProgressBar to small?

What is the difference between `android:windowBackground` and `android:colorBackground`?

Example:

    &lt;style name = &quot;theme&quot;&gt;
     &lt;item name =&quot;android:windowBackground&quot;&gt;@color/black&lt;/item&gt;
     &lt;item name =&quot;android:colorBackground&quot;&gt;@color/black&lt;/item&gt;
    &lt;/style&gt;

Which one would affect the color you see when a new activity is loading?

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 working with the CollapsingToolbarLayout from the new Android Design Support Library.

I have set its title and it is working fine, the only problem I still have is that when you scroll, the text is lost, depending on the image in the background. 

What I&#39;d like to do, is set a background to the CollapsingToolbarLayout title, but I haven&#39;t find a way to do it.

Is there anyway to achieve this?

Setting up the CollapsingToolbarLayout title in the activity:

                (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
        collapsingToolbar.setTitle(&quot;Some title here&quot;);

Edit:

Here you can see a sequence of images when I collapse the toolbar. You can see how the title text is not readable. The problem is that I don&#39;t have control of the images that I show, so for some images it looks ok, but for others, like this example, it doesn&#39;t look good at all and it is not readable. What I had in mind was maybe add some kind of background to the text, so there is always the same color at the back of the text and it is always readable.

Android CollapsingToolbarLayout Title background

I&#39;m trying to use the `TextView` constructor with style like this:

    TextView myText = new TextView(MyActivity.this, null, R.style.my_style);


However, when I do this, the text view does not appear to take the style (I verified the style by setting it on a static object).

I&#39;ve also tried using `myText.setTextAppearance(MyActivity.this, R.style.my_style)` but it also doesn&#39;t work.

I&#39;ve updated my SDK to API 21 and now the back/up icon is a black arrow pointing to the left.

![Black back arrow][1]

I would like it to be grey. How can I do that?

In the Play Store, for example, the arrow is white.

I&#39;ve done this to set some styles. I have used `@drawable/abc_ic_ab_back_mtrl_am_alpha` for `homeAsUpIndicator`. That drawable is transparent (only alpha) but the arrow is displayed in black. I wonder if I can set the color like I do in the `DrawerArrowStyle`. Or if the only solution is to create my `@drawable/grey_arrow` and use it for `homeAsUpIndicator`.

    &lt;!-- Base application theme --&gt;

    &lt;/style&gt;

    &lt;!-- ActionBar style --&gt;
    &lt;style name=&quot;MyActionBar&quot; parent=&quot;@style/Widget.AppCompat.Light.ActionBar.Solid&quot;&gt;

        &lt;item name=&quot;android:background&quot;&gt;@color/actionbar_background&lt;/item&gt;
        &lt;!-- Support library compatibility --&gt;
        &lt;item name=&quot;background&quot;&gt;@color/actionbar_background&lt;/item&gt;

    &lt;!-- Style for the navigation drawer icon --&gt;
    &lt;style name=&quot;DrawerArrowStyle&quot; parent=&quot;Widget.AppCompat.DrawerArrowToggle&quot;&gt;

        &lt;item name=&quot;color&quot;&gt;@color/actionbar_text&lt;/item&gt;
    &lt;/style&gt;

My solution so far has been to take the `@drawable/abc_ic_ab_back_mtrl_am_alpha`, which seems to be white, and paint it in the color I desire using a photo editor. It works, although I would prefer to use `@color/actionbar_text` like in `DrawerArrowStyle`.

How to change color of the back arrow in the new material theme?

I have created a custom widget, and I&#39;m declaring it in layout.xml.  I have also added some custom attributes in attr.xml.  However, when trying to declare these attributes in a style in styles.xml, it&#39;s giving me `No resource found that matches the given name: attr &#39;custom:attribute&#39;.`

I have put the `xmlns:custom=&quot;http://schemas.android.com/apk/res/com.my.package&quot;` in all of the tags in styles.xml, including `&lt;?xml&gt;`, `&lt;resources&gt;`, and `&lt;style&gt;`, but it still gives me the same error, that it can&#39;t find my custom XML namespace.

I can, however, use my namespace to manually assign attributes to the view in my layout.xml, so there is nothing wrong with the namespace.  My issue lies in making styles.xml aware of my attr.xml.

Cannot resolve symbol &#39;Theme&#39; in styles.xml (Android Studio)

I was wondering if it&#39;s possible to change the statusbar **icons** colour (**not** the statusbar colour, `colorPrimaryDark`)
![enter image description here][1]
Let&#39;s say I want this statusbar with:  
`&lt;item name=&quot;colorPrimaryDark&quot;&gt;@android:color/white&lt;/item&gt;`  

and the icons in black, is it possible?

Thanks.

**EDIT:**
 

&gt; New in the M developer preview: windowLightStatusBar. Flipping this on
&gt; in your theme tells the system to use a dark foreground, useful for
&gt; lighter colored status bars. Note the M preview seems to have a bug
&gt; where notification icons remain white, while system status icons
&gt; correctly change to semitransparent black.

Question mark (?) in XML attributes for Android

I&#39;ve added a **RatingBar** in a layout:

    &lt;RatingBar 
        android:id=&quot;@+id/ratingbar&quot;
    	android:layout_width=&quot;wrap_content&quot;
    	android:layout_height=&quot;wrap_content&quot;
    	android:numStars=&quot;5&quot;
    	android:stepSize=&quot;1.0&quot;
    	/&gt;	

But the default style for the rating bar is too large.  
I&#39;ve try to change it by adding the android style : `style=&quot;?android:attr/ratingBarStyleSmall&quot;`

But the result is too small and it&#39;s impossible to set a rate with this property.

How could I do?

How to make a smaller RatingBar?

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;

Any ideas how I might get this to work?

I am having this issue where I am using the Android&#39;s Holo theme on a tablet project. However, I have a fragment on screen which has a white background. I am adding an `EditText` component on this fragment. I&#39;ve tried to override the theme by setting the background of the Holo.Light theme resources. However, my text cursor (carat) remains white and hence, invisible on screen (I can spot it faintly in the edittext field..).

Does anyone know how I can get EditText to use a darker cursor color? I&#39;ve tried setting the style of the EditText to `&quot;@android:style/Widget.Holo.Light.EditText&quot;` with no positive result.

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.

In my app *&quot;Tide Now WA&quot;* which I recently tested for compatibility using
the new Nexus 9 tablet (Lollipop - API 21).

It writes some button text. This app writes the text correctly using Android 2.3 and Android
4.0. I.e. mixed capital and lower case letters. 

When same app is run on my Nexus 9 all the letters
in the text are capitalized. 

FWIW my manifest contains the following statement:

`uses-sdk android:minSdkVersion=&quot;10&quot; android:targetSdkVersion=&quot;14&quot;`

Can I fix this in my code or is it a bug in the O.S.
thanks

Recently I switched from support library to com.google.android.material:material:1.0.0

But now I have a problem, in this pages there&#39;s a note https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md

&gt; Note: Using a Material Components theme enables a custom view inflater which replaces default components with their Material counterparts. Currently, this only replaces Button XML components with MaterialButton.

And the theme I am using 

    Theme.MaterialComponents.Light.NoActionBar


does exactly what it says in that note, it replaces AlertDialog Buttons to MaterialButtons but the problem is that by default MaterialButtons are colored background and now the buttons looks like this: [![enter image description here][1]][1]

How can I make them borderless and backgroundless again?

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.


Android toolbar center title and custom font

Using the [Fonts in XML][1] feature you can specify various font weights for a font family. For example:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;font-family xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
                 xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_regular&quot; android:fontWeight=&quot;400&quot; android:fontStyle=&quot;normal&quot;
            app:font=&quot;@font/archivo_narrow_regular&quot; app:fontWeight=&quot;400&quot; app:fontStyle=&quot;normal&quot;/&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_regular_italic&quot; android:fontWeight=&quot;400&quot; android:fontStyle=&quot;italic&quot;
            app:font=&quot;@font/archivo_narrow_regular_italic&quot; app:fontWeight=&quot;400&quot; app:fontStyle=&quot;italic&quot;/&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_medium&quot; android:fontWeight=&quot;500&quot; android:fontStyle=&quot;normal&quot;
            app:font=&quot;@font/archivo_narrow_medium&quot; app:fontWeight=&quot;500&quot; app:fontStyle=&quot;normal&quot;/&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_medium_italic&quot; android:fontWeight=&quot;500&quot; android:fontStyle=&quot;italic&quot;
            app:font=&quot;@font/archivo_narrow_medium_italic&quot; app:fontWeight=&quot;500&quot; app:fontStyle=&quot;italic&quot;/&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_semibold&quot; android:fontWeight=&quot;600&quot; android:fontStyle=&quot;normal&quot;
            app:font=&quot;@font/archivo_narrow_semibold&quot; app:fontWeight=&quot;600&quot; app:fontStyle=&quot;normal&quot;/&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_semibold_italic&quot; android:fontWeight=&quot;600&quot; android:fontStyle=&quot;italic&quot;
            app:font=&quot;@font/archivo_narrow_semibold_italic&quot; app:fontWeight=&quot;600&quot; app:fontStyle=&quot;italic&quot;/&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_bold&quot; android:fontWeight=&quot;700&quot; android:fontStyle=&quot;normal&quot;
            app:font=&quot;@font/archivo_narrow_bold&quot; app:fontWeight=&quot;700&quot; app:fontStyle=&quot;normal&quot;/&gt;

        &lt;font android:font=&quot;@font/archivo_narrow_bold_italic&quot; android:fontWeight=&quot;700&quot; android:fontStyle=&quot;italic&quot;
            app:font=&quot;@font/archivo_narrow_bold_italic&quot; app:fontWeight=&quot;700&quot; app:fontStyle=&quot;italic&quot;/&gt;

    &lt;/font-family&gt;

But I cannot figure out how to actually make use of each of these weights; either in an XML (layout/style) file, or in Java code. Their is no `fontWeight` attribute available for `TextView`, and the [`Typeface`][2] object created from [`ResourcesCompat.getFont(context, R.font.archivo_narrow)`][3] has no mention of font weights.

I realize that I can just specify the specific font resource (i.e. `R.font.archivo_narrow_semibold`), but then what is the point of having a `fontWeight` attribute in the `font-family`? 

---

### Update

A new static [`create(Typeface family, int weight, boolean italic)`][4] method was added in API Level 28, along with a [`getWeight()`][5] instance method. This finally makes it possible to make use of the `fontWeight` attribute in Java code; though only for API Level 28 and above, I haven&#39;t found any analogs in the support library.

This is useful—and shows that the `fontWeight` attribute didn&#39;t serve any purpose in the past—but I would really like to be able to use the weight in XML styling.

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;...

I want to change the default color of the date/time picker dialog in Android, so that it should match my app&#39;s theme. I searched for the solution on Google, but I couldn&#39;t find a solution.

What I was doing was creating a new style: 

      &lt;style name=&quot;datepicker&quot; parent=&quot;@android:style/Widget.DeviceDefault.DatePicker&quot;&gt;
        &lt;!---TODO--&gt;
        &lt;item name=&quot;android:focusedMonthDateColor&quot;&gt;@android:color/holo_red_dark&lt;/item&gt;
    &lt;/style&gt;
**Don&#39;t know what are the attributes available for date picker dialogue. It would be great if anyone could post a link on that**

and after adding the style I was calling it in my main style as

     &lt;item name=&quot;android:datePickerStyle&quot;&gt;@style/datepicker&lt;/item&gt;

Unfortunately, this didn&#39;t work for me at all.

Android Toolbar: small title text in landscape mode

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)

I am using appcompat v7 to get the look consistent on Android 5 and less. It works rather well. However I cannot figure out how to change the bottom line color and the accent color for EditTexts. Is it possible? 

I have tried to define a custom `android:editTextStyle` (cf. below) but I only succeeded to change the full background color or text color but not the bottom line nor the accent color. Is there a specific property value to use? do I have to use a custom drawable image through the `android:background` property? is it not possible to specify a color in hexa?

     &lt;style name=&quot;Theme.App.Base&quot; parent=&quot;Theme.AppCompat.Light.DarkActionBar&quot;&gt;
         &lt;item name=&quot;android:editTextStyle&quot;&gt;@style/Widget.App.EditText&lt;/item&gt;
     &lt;/style&gt;

     &lt;style name=&quot;Widget.App.EditText&quot; parent=&quot;Widget.AppCompat.EditText&quot;&gt;
         ???
     &lt;/style&gt;

According to android API 21 sources, EditTexts with material design seem to use `colorControlActivated` and `colorControlNormal`. Therefore, I have tried to override these properties in the previous style definition but it has no effect. Probably appcompat does not use it. Unfortunately, I cannot find the sources for the last version of appcompat with material design.
