在Android中刷卡聽衆

Question

Android中有沒有類似onLeftSwipeListener和onRightSwipeListener的東西？我想切換視圖向前和向後滑動手指。我在裏面使用了一個FrameLayout和一個ImageView。

Answer 1

它叫做GestureDetector和SimpleOnGestureListener它有onFling()。其所謂一扔，而不是在這方面:)

Answer 2

下面是有關實現手勢檢測相關quetion刷卡：

Fling gesture detection on grid layout

你也可以使用一個ViewFlipper有一些動畫的視圖之間切換，它看起來好，這裏是爲使上viewflipper左/右輕掃的範例：

Answer 3

我已經刷卡我的一個小例子ñ安卓我想與你分享代碼。

赤這個。

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; 
      }
