How to use onCreateOptionsMenu () in activity that has Extended ListActivity
I have a problem with my android app project.
I have a MainActivity which is below:
public class MainActivity extends ListActivity {
private NotesDataSource datasource;
List<NoteItem> notesList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
datasource = new NotesDataSource(this);
refreshDisplay();
}
private void refreshDisplay() {
notesList = datasource.findAll();
ArrayAdapter<NoteItem> adapter = new ArrayAdapter<NoteItem>(this, R.layout.list_item_layout, notesList);
setListAdapter(adapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
}
And also I have menu_main.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item android:id="@+id/action_create"
android:title="@string/action_create"
android:orderInCategory="100"
app:showAsAction="always|withText"
android:icon="@drawable/create_note"/>
</menu>
At this point, the problem begins. I changed my superclass from ActionBarActivity to ListActivity , then when I launch my app on my device, I don't see the create icon (and the top menu that includes the app name). What's wrong? And the idea?
(I'm using Android Studio Ide by the way)

Your theme is probably still based on Theme.AppCompat
. If you want to use Theme.AppCompat
, you must inherit from ActionBarActivity
. If you want to use ListActivity
, you cannot use Theme.AppCompat
.
Note that you don't need to use ListActivity
to have it ListView
in action. Here is a sample project demonstrating use Theme.AppCompat
with ActionBarActivity
and ListView
. Here's another example project , just like the previous one, except I'm applying custom tints to the action bar.
