ViewFlipper no voltea con lista de niños

Question

ViewFlipper no funciona al deslizar. Si pongo otra vista en lugar de la vista de lista, el cambio funciona bien. ¿Hay algún otro código que deba agregar para una vista de lista? Y la vista de desplazamiento dentro de la visión aleta también que no trabaja para mí :( Este es mi código XML

<?xml version="1.0" encoding="utf-8"?> 
<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/vf" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 

    <LinearLayout 
     android:layout_width="fill_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical"> 

     <ListView 
      android:id="@+id/list1" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"/> 
    </LinearLayout> 
    <LinearLayout 
     android:layout_width="fill_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical"> 
     <ListView 
      android:id="@+id/list2" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"/> 
    </LinearLayout> 
</ViewFlipper> 

Este es mi código de clase.

    class MyGestureDetector extends SimpleOnGestureListener { 
     @Override 
     public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
       float velocityY) { 
      try { 
       if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) 
        return false; 
       // right to left swipe 
       if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE

        viewFlipper.setInAnimation(slideLeftIn); 
        viewFlipper.setOutAnimation(slideLeftOut); 
        viewFlipper.showNext(); 
       } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE

      } catch (Exception e) { 
       // nothing 
      } 
      return false; 
     } 
    } 

    @Override 
    public boolean onTouchEvent(MotionEvent event) { 
     if (gestureDetector.onTouchEvent(event)) 
      return true; 
     else 
      return false; 
    } 
} 

Anulación dispatchTouchEvent en lugar de onTouchEvent hace tanto en la vista de desplazamiento y funcionando bien gesto.

@Override 
public boolean dispatchTouchEvent(MotionEvent event) { 
    super.dispatchTouchEvent(event); 
    return gestureDetector.onTouchEvent(event); 
} 

Answer 1

desplazamiento no está haciendo efecto, como ya se ha overrided ge Por lo tanto, también debe tomar el efecto de desplazamiento manualmente, en el caso.
