OnTouchListener没有响应

Question

I am creating a little popup like the facebook's chathead.

The bubble fires up and appears but the ontouchlistener is not responding on it

the ontouch events does what It is supposed to do when I tested it but when I integrated it, it's not firing

Below is the code I used to create the layout of the bubble and ontouchlistener

public HeadLayer(Context context) {
    super(context);

    mContext = context;
    mFrameLayout = new FrameLayout(mContext);

    addToWindowManager();
}

private void addToWindowManager() {
    final WindowManager.LayoutParams myParams = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_PHONE,
            WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
            PixelFormat.TRANSLUCENT);
    myParams.gravity = Gravity.LEFT;

    mWindowManager = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);
    mWindowManager.addView(mFrameLayout, myParams);

    try{
        LayoutInflater layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        // Here is the place where you can inject whatever layout you want.
        View view = layoutInflater.inflate(R.layout.head, mFrameLayout);

        //for moving the picture on touch and slide
        headIcon = (ImageView)view.findViewById(R.id.head_icon);

        headIcon.setOnTouchListener(new View.OnTouchListener() {
            WindowManager.LayoutParams paramsT = myParams;
            private int initialX;
            private int initialY;
            private float initialTouchX;
            private float initialTouchY;
            private long touchStartTime = 0;

            @Override
            public boolean onTouch(View v, MotionEvent event) {

                switch(event.getAction()){
                    case MotionEvent.ACTION_DOWN:
                        touchStartTime = System.currentTimeMillis();
                        initialX = myParams.x;
                        initialY = myParams.y;
                        initialTouchX = event.getRawX();
                        initialTouchY = event.getRawY();
                        break;
                    case MotionEvent.ACTION_UP:
                        break;
                    case MotionEvent.ACTION_MOVE:
                        myParams.x = initialX + (int) (event.getRawX() - initialTouchX);
                        myParams.y = initialY + (int) (event.getRawY() - initialTouchY);
                        mWindowManager.updateViewLayout(v, myParams);
                        break;
                }
                return false;
            }
        });
    } catch (Exception e){
        e.printStackTrace();
    }
}

Hi You have added Framelayout first then get its child Using LayoutInflator. You have to first initialize all view and listeners then added it to window manager.
