Android Question

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

I'm trying to create simple application using android-support-v7:21 library.


Code snippets:


MainActivity.java

public class MainActivity extends ActionBarActivity {

Toolbar mActionBarToolbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
mActionBarToolbar.setTitle("My title");
setSupportActionBar(mActionBarToolbar);
}


activity_main.xml

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar_actionbar"
android:background="@null"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:fitsSystemWindows="true" />

</LinearLayout>


But instead of "My title" on Toolbar %application name% is shown.

Seems like
setTitle
method has no effect.

I would like to show "My title".


UPD:
Before,
styles.xml
was:

<style name="AppTheme" parent="Theme.AppCompat">
<item name="windowActionBar">false</item>
</style>


So, I thought that actionbar is not used.
I add
NoActionBar
to style parent:

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<item name="windowActionBar">false</item>
</style>


But the problem is not resolved.

Any help is very appreciated.

Answer

Found the solution:
Instead of:

mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);            
mActionBarToolbar.setTitle("My title");
setSupportActionBar(mActionBarToolbar);

I use:

mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);            
setSupportActionBar(mActionBarToolbar);
getSupportActionBar().setTitle("My title");

And it works.
