Answer 1

试试这个代码：

 new Handler().postDelayed(new Runnable(){

    public void run() {
       popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER,0,0);
    }

}, 200L);

代替：

popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER,0,0);

还要确保您ActivityName.this作为上下文传递..而不是getApplicationContext()

尝试用以下代码替换您的runnable代码showPopUpWindow()：

runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if (!isFinishing()) {
                popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER, 0, 0);
            }
        }
    });
