TWO

LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View v = inflater.inflate(R.layout.pop_login, null);
//        View v = View.inflate(getContext(),R.layout.pop_login, null);


        popupWindow = new PopupWindow(v, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        popupWindow.setFocusable(true);
        popupWindow.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);
        popupWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        popupWindow.setOutsideTouchable(true);
        //设置渐入、渐出动画效果
        popupWindow.setAnimationStyle(android.R.style.Animation_Toast);
        popupWindow.setTouchable(true);
        popupWindow.setFocusable(true);
        popupWindow.setBackgroundDrawable(new BitmapDrawable());
        popupWindow.setOutsideTouchable(true);
        popupWindow.setTouchInterceptor(new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
                    popupWindow.dismiss();
                    return true;
                }
                return false;
            }
        });

   // popupWindow.update();
        popupWindow.showAtLocation(view, Gravity.BOTTOM, 0, 0);
//        popupWindow.showAsDropDown(view,100,-150);

点击事件中的view就是父容器

public void onViewClicked(View view) {
    switch (view.getId()) {
case R.id.rl_touxiang_personalCenter:
    showPopWindow(view);
    break;
    }
}
