Android：onClick按钮onClick很少被调用

Question

如果我点击按钮然后它移动1,2个像素（执行ontouch（））但没有点击（onclick（））...但如果我准确点击然后它点击但是它太难以执行onclick（） finctionality ....有没有办法执行onclick功能轻松... ontouch（）功能正常工作。

        WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);

    overlayedButton = new Button(this);
    overlayedButton.setWidth(50);
    overlayedButton.setHeight(50);
    overlayedButton.setText("butn");
    overlayedButton.setOnClickListener(this);
    overlayedButton.setOnTouchListener(this);



    WindowManager.LayoutParams params = new WindowManager.LayoutParams(70, 70, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, PixelFormat.TRANSLUCENT);
    params.gravity = Gravity.LEFT | Gravity.TOP ;
    params.x = 0;
    params.y = 0;
    wm.addView(overlayedButton, params);


    @Override
