ID多點觸摸問題

在下面的代碼中，我正在測試我的設備上的多點觸摸。我遇到的問題是移動操作。如果我用一根手指觸摸屏幕，我會在Logcat中獲得觸摸輸入的ID，並且當我用另一個手指觸摸屏幕並開始移動屏幕時，我得到兩個手指的ID，儘管手指沒有「不要動！我很困惑，需要一些幫助來改進我的代碼。ID多點觸摸問題

@Override 
public boolean onTouch(View v, MotionEvent event) { 
    int pointerId; 
    int pointerIndex; 

    synchronized (gameLoop) { 
     for (int i = 0; i < event.getPointerCount() && i < 2; i++) { 

      num = event.getPointerCount(); 
      //id = event.getPointerId(i); 

      // Down 
      if(event.getActionIndex() == i && (event.getActionMasked() == MotionEvent.ACTION_POINTER_DOWN || event.getActionMasked() == MotionEvent.ACTION_DOWN)) { 

       int j = event.getPointerCount(); 
       int id = event.getPointerId(i); 
       String numDown = Integer.toString(j); 
       String sId = Integer.toString(id); 
       Log.i("Test", "Number DOWN: " + numDown + " ID: " + sId); 
      } 

      // Move 
      if(event.getActionMasked() == MotionEvent.ACTION_MOVE) { 

       int j = event.getPointerCount(); 
       int id = event.getPointerId(i); 
       String numDown = Integer.toString(j); 
       String sId = Integer.toString(id); 
       Log.i("Test", "Moving: " + numDown + " ID: " + sId); 
      } 

      // Up 
      if(event.getActionIndex() == i && (event.getActionMasked() == MotionEvent.ACTION_POINTER_UP || event.getActionMasked() == MotionEvent.ACTION_UP)) { 

       int k = event.getPointerCount(); 
       int kid = event.getPointerId(i); 
       String numUp = Integer.toString(k); 
       String ssId = Integer.toString(kid); 
       Log.i("Test", "Number UP: " + numUp + " ID: " + ssId); 
      } 
     }

    return true;

case MotionEvent.ACTION_MOVE: 

     int j= event.getPointerCount(); 

     int fingerOneDown=0; 
     int fingerTwoDown=0; 
     for(int i = 0; i < j; ++i) 
     { 
      int pointerIndex = i; 
      id= event.getPointerId(pointerIndex); 
      Log.d("pointer id - move",Integer.toString(id)); 
      if(id== 0) 
      { 
       fingerOneDown = 1; 
       int fingerOneX = event.getX(pointerIndex); 
       int fingerOneY = event.getY(pointerIndex); 
       Log.e("finger touch","touch=="+fingerOneX+","+fingerOneY); 

      } 
      if(pointerId == 1) 
      {
