View flipper is not flipping

Is this even possible? I created this view flipper and I am calling the view flipper from the onClick inside of the xml layout. I have created a view flipper before but for some reason it's not working.

code:

public class BeatSpotPrototypeActivity extends BaseListActivity {
private final String TAG = BeatSpotPrototypeActivity.class.getSimpleName();
private ApplicationStateManager mAppStateMananger = ApplicationStateManager.GetInstance();
private Context mCtx = null;
private boolean mIsInitalized = false;
private boolean mDataChanded= false;
private ViewFlipper mViewFlipper= null;
private DrawableManager mDrawManager = new DrawableManager();
private enum ViewFlipperModes {
MAIN (0),
NOW_PLAYING (1),
SONG_INFORMATION (2);

private final int index;

ViewFlipperModes(int index) {
this.index = index;
}

public int index() {
return index;
}
}
</code>
<code>
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_beatspot_activity);

if (!mIsInitalized)
init();
else
mDataChanded = true;
showLoading(false);

}

private void init() {
mCtx = this;
mIsInitalized = true;
mViewFlipper = (ViewFlipper)findViewById(R.id.viewFlipper);
fadeDrawables();
}


public void gotoBeatspotMain(View v) {
mViewFlipper.setDisplayedChild(ViewFlipperModes.MAIN.index());
}

public void gotoNowPlaying(View v) {
Log.d(TAG, mViewFlipper.getCurrentView().toString());
mViewFlipper.setDisplayedChild(ViewFlipperModes.NOW_PLAYING.index());
}

public void gotoSongDetails(View v) {
mViewFlipper.setDisplayedChild(ViewFlipperModes.SONG_INFORMATION.index());
Log.d(TAG, String.valueOf(ViewFlipperModes.SONG_INFORMATION.index()));
}

}

Answer

before on create

ViewFlipper mViewFlipper = (ViewFlipper)findViewbyId(location);

on your onCreate() or onStart

Ensure that whatever your layout on setcontentView(R.layout.something) does contain the view flipper

Also try this for me. before this line mViewFlipper.setDisplayedChild(ViewFlipperModes.MAIN.index()); Type in:

int i = (ViewFlipperModes.MAIN.index()); place a debug point here
mViewFlipper.setDisplayedChild(i);

I also suggest using the debugger to try figure out if your flip views events are being called inside the debugger.
