具有AppCompat和ActionBar的NullPointerExcetption

Question

The Activity I have crashes everytime with this error. If I add any code related to getSupportActionBar() it crashes within that. Otherwise it crashes out of that

public class DishTag extends ActionBarActivity  implements OnClickListener{
 //....
    @Override
    protected void onCreate(Bundle savedInstanceState) {
       setContentView(R.layout.dish_tag);
       super.onCreate(savedInstanceState);
       context=this;
       //literally all the code I have
       ActionBar a=getSupportActionBar();
       a.setTitle("SD"); 
    }
}

To be noted and I don't know if this makes any difference but I am using a ViewPager on the page.

The error is

11-30 22:06:38.212: E/AndroidRuntime(27315): Caused by:java.lang.NullPointerException
Attempt  to invoke virtual method 'java.lang.Class java.lang.Object.getClass()' on a
null object reference

Answer 1

So I found the answer.

I tried setting the content view before runnning the onCreate

protected void onCreate(Bundle savedInstanceState) {
        setContentView(R.layout.dish_tag);
        super.onCreate(savedInstanceState);
}
