You are using wrong getActionBar method.
You are using AppCompatActivity so action bar is from supported library.
You should use ((AppCompatActivity) getActivity()).getSupportActionBar();
If you not make cast getActionBaris asking about android.app.ActionBar
but using AppCompatActivity you need to ask about android.support.v7.app.ActionBar

How to connect code with the layout (.xml) after I selected it in a Navigation Drawer?

If I select something in the Navigation Drawer, it switches layouts but how do I bring code behind it?
I normally had different classes and opened them with Intent. So the code was always in the Classfor the specific layout. But now I wan't to navigate through a Navigation Drawer.
First.java: Thats how I navigate now, but how to connect the code from Second.java which is for secondlayout.xml?

Java NullPointerException on onTouchListener

I'm having some difficulties in building my first application on Android.
I've follow the tutorial from Google to make an app with a drawer it works but when I want to put something else than a picture it crash my app.
My layout appears correctly on my AVD device but when I put an onTouchListener i get a Java NullPointerException.
I suspect that it come from the fact that i don't use the good layout but I can't figure out why. Any idea ?
Thanks a lot !

Add this line inside onCreate():
TxtResultat = (textView) findViewById(R.id.**your textview's id**);
You just created a reference of the class TextView but not allocating it memory, this is why you were receiving the error of NullPointerException

You initialize null to TxtResultat
TextView TxtResultat = null;
this below line give you null pointer exception because it intialize null
TxtResultat.setText("TEST")

Give a try to this:
OnTouchListener touchListenerBouton1 = new View.OnTouchListener()
{
#Override
public boolean onTouch(View v, MotionEvent event)
{
TxtResultat.setText("TEST");
return true;
}
};
b1 = (Button) findViewById(R.id.button1);
b1.setOnTouchListener(touchListenerBouton1);
Seems b1 is null or tourchListenerBouton is null. put a break point and initialize the one which is null.

NavigationDrawer onCreate empty activity

I followed this example: http://javatechig.com/android/navigation-drawer-android-example to create a navigation drawer in my application. I can create it but it shows my fragment only when i click in the first menu item. I would create directly the on onCreate my first fragment without click the item because that will be another one frag. How can i do it? This is the nav drawer Activity that starts onClick the fragment:
public class MainNavDrawer extends Activity {
// Within which the entire activity is enclosed
private DrawerLayout mDrawerLayout;

private ListView mDrawerList;
public TextView textview;
// ActionBarDrawerToggle indicates the presence of Navigation Drawer in the action bar

As you can see onClick it opens my MainActivity (It's a fragment). But i want display it when i open the application not when i click. Thanks

This wasn't really hard. I was getting error, because I have having error in my xml files.
