viewFlipper с жестом

Question

Я работаю над viewFlipper с жестом. но этот жест не работает для перехода на следующую страницу.

Я установил следующий и перед жестом, как <,> чтобы перейти на следующую страницу, установив жесты.

Я не знаю, что не так с моим кодом.

AndroidViewFlipper

public class AndroidViewFlipperActivity extends Activity { 

ViewFlipper page; 
GestureLibrary mLibrary; 
GestureOverlayView gestures; 

AnimationSet animSetFlipInForeward; 
AnimationSet animSetFlipOutForeward; 
AnimationSet animSetFlipInBackward; 
AnimationSet animSetFlipOutBackward; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    page = (ViewFlipper)findViewById(R.id.flipper); 

    gestures = (GestureOverlayView) findViewById(R.id.gestures); 
    gestures.addOnGesturePerformedListener(mListener); 
    mLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures); 



} 

OnGesturePerformedListener mListener = new OnGesturePerformedListener() { 
public void onGesturePerformed(GestureOverlayView overlay,Gesture gesture) { 
     ArrayList<Prediction> predictions = mLibrary.recognize(gesture); 
     if (predictions.size() != 0) { 
      Prediction prediction = predictions.get(0); 
      String name = prediction.name; 
      if (prediction.score > 1.0) { 
       if(name.equals("prev")){ 
        Log.i("tag","next1"); 
        SwipeRight(); 
       }else if(name.equals("next")){

Делают это так:

OnGesturePerformedListener mListener = new OnGesturePerformedListener() { 
public void onGesturePerformed(GestureOverlayView overlay,Gesture gesture) { 
     ArrayList<Prediction> predictions = mLibrary.recognize(gesture); 
     for (Prediction prediction : predictions) { 
     if (predictions.size() != 0) { 
      String name = prediction.name; 
      if (prediction.score > 1.0) { 
       if(name.equals("prev")){ 
        Log.i("tag","next1"); 
        SwipeRight(); 
       }else if(name.equals("next")){ 
        Log.e("tag","next2"); 
        SwipeLeft(); 
       } 
      } 
     } 
     } 
    } 
};
