的Android - onTouch不工作

這是我的代碼：的Android - onTouch不工作

public class ViewSecond extends View implements View.OnTouchListener{

我想要當用戶觸摸屏幕來檢測，但它不工作，我試圖把它（onTouch方法）在這裏和在活動中，但沒有做：/任何想法？您是否看到我的drawImages？最後，我想要檢測點擊這個圖像。 Thx：D

如果你擴展一個View使用onTouchEvent，而不是onTouch – pskink 2015-04-03 06:28:05

嗨，如果你想重寫公共布爾onTouch（視圖v，MotionEvent事件）。如果你想處理整個控件，那麼返回false，否則返回true。在你的情況下，你返回false，請更新它，並嘗試返回true。例如見下面的onTouch視圖方法。

public boolean onTouch(View view, MotionEvent event) { 
    final int X = (int) event.getRawX(); 
    final int Y = (int) event.getRawY(); 
    switch (event.getAction() & MotionEvent.ACTION_MASK) { 
     case MotionEvent.ACTION_DOWN: 
      break; 
     case MotionEvent.ACTION_UP: 
      break; 
     case MotionEvent.ACTION_POINTER_DOWN: 
      break; 
     case MotionEvent.ACTION_POINTER_UP: 
      break; 
     case MotionEvent.ACTION_MOVE: 
      break; 
    } 
    _root.invalidate(); 
    return true; 
}}

看到它返回true。謝謝。

您應該使用onTouchEvent()而不是簡單的onTouch()並返回true。如果你將返回true這意味着你已經消費了觸摸事件，並且你告訴Android它不需要進一步處理事件。

public boolean onTouchEvent(MotionEvent event) { 
    float x = event.getX(); 
    float y = event.getY(); 
    if(((x>100) && (x<550)) && ((y>100) && (y<550))){ 
     this.vibrator.vibrate(500); 
    } 
    this.invalidate(); 
    return true; 
}
