I want to use the Separator control in a vertical way (Lets say in a horizontal StackPanel).

Searching around I found this method but it doesn&#39;t use the Separator control rather it uses borders and rectangles.

How to set a custom font to the title in toolbar android

I&#39;ve been looking for an answer and I&#39;ve tried many possible solutions, but nothing seems to work..

I&#39;m trying to setup a Material Action Bar following [this tutorial][1].

Here&#39;s my code:

I am using a toolbar in place of actionbar and i am also using a navigation drawer.My toolbar colour is black and i want my navigation drawer indicator colour to be white.So how to change the colour of the navigation drawer indicator or put a custom navigation indicator in v7.Can any one please help me?

Change the color of Navigation Drawer indicator icon

I&#39;m currently in the process of learning how to convert my app to Material design and I&#39;m a bit stuck right now. I&#39;ve got the Toolbar added and I have made my navigation drawer overlay all the content.&lt;br&gt;&lt;br&gt;I&#39;m now trying to create an expandable search that looks like the one in the [material guidelines][1]:
![enter image description here][2]&lt;br&gt;&lt;br&gt;
This is what I&#39;ve got right now and I can&#39;t figure out how to make it like the above:  
![My search][3]

This is my menu xml:
    
    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;menu xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;&gt;
        &lt;item
            android:id=&quot;@+id/action_search&quot;
            android:icon=&quot;@android:drawable/ic_menu_search&quot;
            android:title=&quot;Search&quot;
            app:showAsAction=&quot;always&quot;
            app:actionViewClass=&quot;android.support.v7.widget.SearchView&quot; /&gt;
    &lt;/menu&gt;

That works, I get a menu item that expands to the SearchView and I can filter my list fine. It doesn&#39;t look anything like the 1st picture though.&lt;br&gt;&lt;br&gt;
I tried to use `MenuItemCompat.setOnActionExpandListener()` on `R.id.action_search` so I could change the home icon to a back arrow, but that doesn&#39;t seem to work. Nothing gets fired in the listener. Even if that worked it still wouldn&#39;t be very close to the 1st image.&lt;br&gt;&lt;br&gt;
How do I create a SearchView in the new appcompat toolbar that looks like the material guidelines?

Creating a SearchView that looks like the material design guidelines

I&#39;m using the new v7 Toolbar and for the life of me can&#39;t figure out how to change the color of the title.  I&#39;ve set the @style of the Toolbar to a style declared in styles.xml and applied a titleTextStyle with a textColor.  Am I missing something?  I&#39;m coding for Lollipop but testing currently on a Kitkat device.

**styles.xml**

How do you set the title color for the new Toolbar?

How to set Toolbar text and back arrow color

Jetbrains changed the toolbars in IntelliJ 13.

The Navigate Back &amp; Forward arrows, shown here, used to be in the top toolbar and easily clickable.

![back/forward][1]
Now the only way I can find to access these fields is to go to Navigate -&gt; Back or Navigate -&gt; Forward. 

Does anyone know of a way to add these back/forward locations into an **always visible** toolbar like they were located in IntelliJ 12?

I am using a android.support.v7.widget.Toolbar and learned from [this post][1] how to change the color of the hamburger icon to white, but the up/back arrow remains a dark color when I call

How can I make the arrow white as well?

Here is what my toolbar looks like when I call setDisplayHomeAsUpEnabled():

In a nested WPF ToolBarPanel-ToolBar-Menu we want to get rid of the grip handle to the left and the overflow area to the right. they are both grayed out, but we&#39;d like them to not be displayed at all.

any ideas on how to accomplish that?

just in case my terms aren&#39;t entirely correct, if you look at the image in Figure 3 of the link below, on the lowest of the three toolbars there&#39;s the grip to the left of the dropdown and to the right of the right-most button there&#39;s the overflow.

WPF ToolBar: how to remove grip and overflow

When I use drawables from the `AppCompat` library for my `Toolbar` menu items the tinting works as expected. Like this:

    &lt;item
        android:id=&quot;@+id/action_clear&quot;
        android:icon=&quot;@drawable/abc_ic_clear_mtrl_alpha&quot;  &lt;-- from AppCompat
        android:title=&quot;@string/clear&quot; /&gt;

But if I use my own drawables or actually even copy the drawables from the `AppCompat` library to my own project it will not tint at all.

    &lt;item
        android:id=&quot;@+id/action_clear&quot;
        android:icon=&quot;@drawable/abc_ic_clear_mtrl_alpha_copy&quot;  &lt;-- copy from AppCompat
        android:title=&quot;@string/clear&quot; /&gt;

Is there some special magic in the `AppCompat` `Toolbar` that only tint drawables from that library? Any way to get this to work with my own drawables?

Running this on API Level 19 device with `compileSdkVersion = 21` and `targetSdkVersion = 21`, and also using everything from `AppCompat`

`abc_ic_clear_mtrl_alpha_copy` is an exact copy of the `abc_ic_clear_mtrl_alpha` png from `AppCompat`

**Edit:**

The tinting is based on the value I have set for `android:textColorPrimary` in my theme.

E.g. `&lt;item name=&quot;android:textColorPrimary&quot;&gt;#00FF00&lt;/item&gt;` would give me a green tint color.

I am trying to follow the Google Docs on using the CoordinatorLayout but i am having an issue with the ScrollView inside the CoordinatorLayout. Basically, the Toolbar normally would collapse with a RecyclerView or a Listview when scrolling down. Now with a ScrollView it will not collapse.

Here is a screenshot of Google Maps Toolbar.

![Google Maps Toolbar][1]

As you can see icons are aligned to the left instead of right (default behavior). I&#39;ve tried adding android:layout_gravity=&quot;left&quot; and android:gravity=&quot;left&quot; to the toolbar but it didn&#39;t work. I also tried adding an internal LinearLayout (with same gravity values) to the Toolbar but that didn&#39;t work either. Any ideas? 

I want to be able to use a regular Android menu with the Toolbar widget instead of recreating everything from scratch.

    &lt;style name=&quot;AppTheme&quot; parent=&quot;Theme.AppCompat&quot;&gt;
        &lt;item name=&quot;windowActionBar&quot;&gt;false&lt;/item&gt;
    &lt;/style&gt;

So, I thought that actionbar is not used.
I add `NoActionBar` to style parent:

    &lt;style name=&quot;AppTheme&quot; parent=&quot;Theme.AppCompat.NoActionBar&quot;&gt;
        &lt;item name=&quot;windowActionBar&quot;&gt;false&lt;/item&gt;
    &lt;/style&gt;

But the problem is not resolved.

In android app Toolbar.setTitle method has no effect – application name is shown as title

I have a problem that I don&#39;t know how to solve. How do you hide a toolbar in a specific fragment, I have already been searching around on the internet and what I found was communicating activity and fragment would solve it. But it doesn&#39;t work for me at all, here is my code:

main_activity:

    public class MainActivity extends ActionBarActivity implements like_frag.OnHideToolbar{

    ....

    public void onHidingToolbar(int position){
            Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
            if(toolbar == null){
                getSupportActionBar().hide();
            }else{
                getSupportActionBar().hide();
            }
        }
like_frag.java

    public class like_frag extends Fragment {
    
        OnHideToolbar mCallback;
        Toolbar toolbar;
    
        public interface OnHideToolbar {
            public void onHidingToolbar(int position);
        }
    
        public void onAttach(Activity activity){
    
            try{
                mCallback = (OnHideToolbar) activity;
            }catch(ClassCastException e){
                throw new ClassCastException(activity.toString() + &quot;error implementing&quot;);
            }
        }
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
            View rootView = inflater.inflate(R.layout.swipefrag, container, false);
    
            toolbar = (Toolbar)getActivity().findViewById(R.id.toolbar);
    
            return rootView;
        }
    
        @Override
        public void onCreate(Bundle savedInstanceState){
            super.onCreate(savedInstanceState);
        }
    }

thanks in advance.

android hide toolbar in specific fragment

I have a dialog fragment in which I have toolbar in layout. 
I want to make back button(Navigation Icon) working in toolbar and exit the fragment when clicked. But I am unable to catch the click event on the toolbar&#39;s navigation icon in the (dialog)fragment.

Here is how I am getting toolbar :
 
    toolbar = (Toolbar) rootView.findViewById(R.id.toolbar);
    toolbar.setNavigationIcon(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
    toolbar.setTitle(itemType);
    ((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);

Here is my layout file for the dialog fragment : 

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;RelativeLayout          xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;
        android:orientation=&quot;vertical&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;
        android:background=&quot;@color/panel_cyan&quot;
        android:id=&quot;@+id/rootLayout&quot;
        &gt;

    &lt;android.support.v7.widget.Toolbar
        android:id=&quot;@+id/toolbar&quot;
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;?attr/actionBarSize&quot;
        android:layout_alignParentLeft=&quot;true&quot;
        android:layout_alignParentStart=&quot;true&quot;
        android:layout_alignParentTop=&quot;true&quot;
        android:background=&quot;@color/color_primary&quot;
        android:theme=&quot;@style/ThemeOverlay.AppCompat.Dark.ActionBar&quot;
        app:popupTheme=&quot;@style/ThemeOverlay.AppCompat.Light&quot; /&gt;

    &lt;ListView
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;
        android:id=&quot;@+id/listViewItems&quot;
        /&gt;

    &lt;/RelativeLayout&gt;

**Here is what is have tried so far but failed **

Options item click in id R.id.home

     @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            int id = item.getItemId();
            switch (id){
                case android.R.id.home:
                    finish();
                    break;
            }
            return super.onOptionsItemSelected(item);
        }

setNavigationOnClick() on the toolbar :

    toolbar.setNavigationOnClickListener(new View.OnClickListener(){
                @Override
                public void onClick(View view) {
                    Toast.makeText(getActivity(), &quot;Back clicked!&quot;,     Toast.LENGTH_SHORT).show();
                }
            });
