onClickListener 用于 popupWindow 之外的触摸

Question

从问题Issue dismissing popup window我学会了如何隐藏popupWindow（在此之前，下面代码中的popupWindow.dismiss();不起作用）。

private void initFAB(){
        fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {

        boolean showPopupWindow = false;

        public void onClick(View view) {

            LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
                    .getSystemService(LAYOUT_INFLATER_SERVICE);
            View popupWindowContent = layoutInflater.inflate(R.layout.popup_window_content, null);
            final PopupWindow popupWindow = new PopupWindow(popupWindowContent,
                    ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            popupWindow.setOutsideTouchable(true);

            if (!showPopupWindow){
                rotateFabForward();

                View.OnClickListener onClickListener = new View.OnClickListener() {
                    public void onClick(View view) {
                        //...
                    }
                };

                // ...

                popupWindow.showAtLocation(fab, Gravity.END | Gravity.BOTTOM, 50, 400);
                showPopupWindow = true;
            }
            else{
                rotateFabBackward();
                popupWindow.dismiss();
                showPopupWindow = false;
            }
        }
    });
}

现在，当我在 popupWindow 外部单击它消失时，FloatingActionButton 不会向后旋转（当 popupWindow 隐藏时它有 + 图标并且旋转 45 度，当 popupWindow 可见时，图标变为 ×）。

任何允许在 popupWindow 之外注册触摸并执行 rotateFabBackward() 的侦听器？

P. S. 另外，感谢您回答关于 FAB 轮换的问题。

你应该像那样添加 onDismiss 监听器

popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
    @Override
    public void onDismiss() {
        rotateFabBackward();
        showPopupWindow = false;
        // end may TODO anything else                   
    }
});
