I recently bought an application, and I am still modifying it, but I can not change the title of the action bar (not for the main one, but for each screen).
I am trying to change the title of the action bar for each activity (facebook, video, photos, etc.), that is, I want the user to enter the photo section the action bar change from the main title to the title of the activity (Photos).
I do not know if I explain, I'm a novice in all this.
Thank you very much for your time.
First create the string resource for the name of the activity in values / strings.xml
For example:
<string name="mi_titulo">Mi actividad</string>
You can change the title from java code, that is, dynamically or from the manifest:
From java code
public class MiActividad extends AppCompatActivity {
String titulo= "mi_actividad";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.setTitle(R.string.mi_titulo);
}
}
From the Manifest
In the manifest, you locate the activity whose title you want to change and add the label attribute with the new value:
<activity android:name=".tu_actividad"
android:label="@string/mi_titulo"/>
