列表视图项向左滑动并向右滑动？

问题描述：

如果是这样，如何应用android滑动左右滚动来打开不同的意图？我想要默认情况下在android中的联系人视图中调用电话或消息。

试试这个：

navigaList.setOnTouchListener(swipeDetector); 
navigaList.setOnItemClickListener(listener); 

OnItemClickListener listener = new OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, 
          long arg3) { 
     if(swipeDetector.swipeDetected()) { 
      if(swipeDetector.getAction() == Action.RL) { 

      } else { 

      } 
     }   
    };

SwipeDetector.java

public class SwipeDetector implements View.OnTouchListener { 

    public static enum Action { 
     LR, // Left to Right 
     RL, // Right to Left 
     TB, // Top to bottom 
     BT, // Bottom to Top 
     None // when no action was detected 
    } 

    private static final String logTag = "SwipeDetector"; 
    private static final int MIN_DISTANCE = 100; 
    private float downX, downY, upX, upY; 
    private Action mSwipeDetected = Action.None; 

    public boolean swipeDetected() { 
     return mSwipeDetected != Action.None; 
    } 

    public Action getAction() { 
     return mSwipeDetected; 
    } 

    public boolean onTouch(View v, MotionEvent event) { 
     switch (event.getAction()) { 
     case MotionEvent.ACTION_DOWN: { 
      downX = event.getX(); 
      downY = event.getY(); 
      mSwipeDetected = Action.None; 
      return false; // allow other events like Click to be processed 
     } 
     case MotionEvent.ACTION_MOVE: { 
      upX = event.getX(); 
      upY = event.getY(); 

      float deltaX = downX - upX; 
      float deltaY = downY - upY; 

      // horizontal swipe detection 
      if (Math.abs(deltaX) > MIN_DISTANCE) { 
       // left or right 
       if (deltaX < 0) { 
        Logger.show(Log.INFO,logTag, "Swipe Left to Right"); 
        mSwipeDetected = Action.LR; 
        return true; 
       } 
       if (deltaX > 0) { 
        Logger.show(Log.INFO,logTag, "Swipe Right to Left"); 
        mSwipeDetected = Action.RL; 
        return true; 
       } 
      } else 

       // vertical swipe detection 
       if (Math.abs(deltaY) > MIN_DISTANCE) { 
        // top or down 
        if (deltaY < 0) { 
         Logger.show(Log.INFO,logTag, "Swipe Top to Bottom"); 
         mSwipeDetected = Action.TB; 
         return false; 
        } 
        if (deltaY > 0) { 
         Logger.show(Log.INFO,logTag, "Swipe Bottom to Top"); 
         mSwipeDetected = Action.BT; 
         return false; 
        } 
       } 
      return true; 
     } 
     } 
     return false; 
    } 
}

为什么你不分享所有的源代码？ – mehmetakifalp

我想你可以通过MotionEvents使用OnTouchListener和捕捉填充，初始和当前运动运动名录的项目，如ACTION_DOWN，ACTION_MOVE，UP或CANCEL。
