oyentes Swipe en Android

Question

¿Hay algo así como onLeftSwipeListener y onRightSwipeListener en Android? Quiero cambiar las vistas deslizando el dedo hacia atrás y hacia adelante. Uso un FrameLayout y un ImageView dentro de él.

Answer 1

Se llama GestureDetector y SimpleOnGestureListener que tiene onFling(). Se llama aventura y no deslizar en este contexto :)

Answer 2

He aquí una quetion relacionada acerca de la implementación de los gestos de detección:

Fling gesture detection on grid layout

También es posible usar un ViewFlipper con un poco de animación para cambiar entre las vistas, se ve bueno, aquí está un ejemplo de implementación para permitir que pase a la izquierda/derecha en un viewflipper:

Answer 3

he hecho un pequeño ejemplo de i swiper En Android, me gustaría compartir el código contigo.

Answer 4

yourView.setOnTouchListner(onThumbTouch); 

    OnTouchListener onThumbTouch = new OnTouchListener() { 
      float previouspoint = 0 ; 
      float startPoint=0; 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       switch(v.getId()) { 
        case R.id.tvDetailsalaujairiyat: // Give your R.id.sample ... 
         switch(event.getAction()){ 
          case MotionEvent.ACTION_DOWN: 
           startPoint=event.getX(); 
           System.out.println("Action down,..."+event.getX()); 
          break; 
          case MotionEvent.ACTION_MOVE: 

          break; 
          case MotionEvent.ACTION_CANCEL: 
           previouspoint=event.getX(); 
           if(previouspoint > startPoint){ 
            //Right side swipe   
           }else{ 
            // Left side swipe 
           }   
          break; 
         } 
        break; 
       } 
       return true;
