Activity does not display action bar
I joined Android Studio and Android App project a few weeks ago and I am trying to create a simple app with ActionBar options.
When I start Android Studio following Android Dev. Learning, I always meet this rendering error:
Android Studio not found. android.support.v7.app.ActionBarActivity (ecc ...)
I solved this error by installing a different theme. But whenever I try a new project, I will do it over and over again. First question: is there a way to fix this rendering issue? I meet this issue also in MainActivity.java where the extends ActionBarActivity is removed with a string telling me it is deprecated and advising me to use AppCompatActivity. Should I follow this advice?
Question number two: I read like 100 posts about guys who can't show an action in action and I've tried everything, but when I link an action menu to an activity via:
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
I still cannot view the menu I created in the action bar. Some images may help me explain my problem better:

And there is a layout for my activity:

As you can see, the icon button that I added is missing and no setting button such as menu display is displayed.

ActionBarActivity
it is now not recommended to use AppCompatActivity
to avoid this error:
Android Studio not found. android.support.v7.app.ActionBarActivity
you need to download the latest Support Library! and then you can use
import android.support.v7.app.AppCompatActivity
public class MainActivity extends AppCompatActivity{
