Answer 1

you can use android:label property in Android Manifest

android:label="This is the Hello World Application"

also you set it dynamically. Create a xml layout titlebar.xml with required layout.

@Override
public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       final boolean titleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
       setContentView(R.layout.main);

       if ( titleSupported ) {
           getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.titlebar);
       }
}
