popupWindowView 是自定义的一个视图

    private void showPopupWindow(View view) {        // 设置按钮的点击事件        TextView wenzhang = (TextView) popupWindowView.findViewById(R.id.wenzhang);        TextView shiping = (TextView) popupWindowView.findViewById(R.id.shiping);        wenzhang.setOnClickListener(this);//设置事件监听        shiping.setOnClickListener(this);        final PopupWindow popupWindow = new PopupWindow(popupWindowView,                ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);        popupWindow.setTouchable(true);//        popupWindow.setTouchInterceptor(new View.OnTouchListener() {//            @Override//            public boolean onTouch(View v, MotionEvent event) {//                Log.i("mengdd", "onTouch : ");//                return false;////                 这里如果返回true的话，touch事件将被拦截////                 拦截后 PopupWindow的onTouchEvent不被调用，这样点击外部区域无法dismiss//            }//        });        // 如果不设置PopupWindow的背景，无论是点击外部区域还是Back键都无法dismiss弹框        // 我觉得这里是API的一个bug   设置一个透明颜色        popupWindow.setBackgroundDrawable(new ColorDrawable(0x00000000));        // 设置好参数之后再show  参数代表xy轴的偏移量        popupWindow.showAsDropDown(view, -14, 8);//        popupWindow.showAsDropDown(view);    }
