Im trying to make a menu that will control the fragments – the screens. (just like in instagram),

But it crashes:

The code of the main activity:

public class All extends Activity {

    Button map;
    Button add;

    View MapFragment;
    View AddFragment;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_all);

        map=(Button)findViewById(R.id.map);
        add=(Button)findViewById(R.id.add);

        MapFragment=(View)findViewById(R.id.MapFragment);
        AddFragment=(View)findViewById(R.id.AddFragment);

        MapFragment.bringToFront();

        map.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                MapFragment.bringToFront();
            }
        });

        add.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                AddFragment.bringToFront();
            }
        });
    }

And the logcat:

line 143 on “Add”:

@Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            return inflater.inflate(R.layout.activity_add, container, false);
        }

Is there something wrong with it?

The layout:

Thanks for your assistance!

Edit

Now Im doing this:

Fragment MapFragment = getSupportFragmentManager().findFragmentById(R.id.MapFragment);
