SimpleOnGestureListener가 onFling (...) 메서드로 절대 들어 가지 않음

Question

안녕하세요 SimpleOnGestureListener가 내 응용 프로그램에서 작동하지 않습니다. 어떻게 구현하나요? 어쩌면 무엇이 잘못되었는지 확인할 수 있습니다. 것은 응용 프로그램이 onFling (...) methode 및 gdt.onTouchEvent (event)로 절대 들어 가지 않는다는 것을 보여주는 디버깅입니다. 항상 false를 반환합니다./ 모든 아이디어 ?? 감사합니다

내 활동 클래스

public class SimpleActivity extends Activity{ 


@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.simpleLayout); 

    final ImageView imageView = (ImageView) findViewById(R.id.gggbbb); 
    imageView.setOnTouchListener(new OnFlingGestureListener() { 

     @Override 
     public void onTopToBottom() { 
      System.out.println("top"); 
     } 

     @Override 
     public void onRightToLeft() { 
      System.out.println("right"); 
     } 

     @Override 
     public void onLeftToRight() { 
      System.out.println("left"); 
     } 

     @Override 
     public void onBottomToTop() { 
      System.out.println("bottom"); 
     } 
    }); 



} 


    }

이 이벤트를 교체 :

@Override 
public boolean onTouch(final View v, final MotionEvent event) { 
    gdt.onTouchEvent(event); 
    return true; 
} 

그것이 작동
