OnClickListener不按要求工作

我有这个代码，问题是在OnClickListener。我通常不会使用onClickListener，但是因为没有活动来设置属性onClick。OnClickListener不按要求工作

当我松开手指即使握住它一段时间后，它也会触发，所以它不会像点击一样感觉到，就像当您制作OnTouchListener和案例：MotionEvent.ACTION_UP。

我需要它只有当你快速触摸它时才会触发。

public class Bubble extends Service{ 
private WindowManager windowManager; 
private ImageView chatHead; 

@Override 
public IBinder onBind(Intent intent){ 
    // TODO Auto-generated method stub 
    return null; 
} 

@Override 
public void onCreate(){ 
    super.onCreate(); 

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE); 
    chatHead = new ImageView(this); 
    chatHead.setImageResource(R.drawable.floating); 

    final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
      WindowManager.LayoutParams.WRAP_CONTENT,

      WindowManager.LayoutParams.TYPE_PHONE, 
      WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,

    params.gravity = Gravity.DISPLAY_CLIP_HORIZONTAL | Gravity.DISPLAY_CLIP_VERTICAL| Gravity.START; 
    params.x = 0; 
    params.y = 100; 
    params.alpha = 0.5f; 
    windowManager.addView(chatHead, params); 

    chatHead.setOnClickListener(new View.OnClickListener(){

Touch通过点击控制。你可以尝试在某些情况下返回true，虽然 –

谢谢，我试过了，但是然后clickListener也不起作用。 –

您可以将您的点击侦听器逻辑移入“ACTION_UP”情况。 – azizbekian

使用GestureDetector检测它是否是单击，并且工作完美。
