BadTokenException:无法添加窗口 - 标记null无效;你的活动正在运行?在activity.isFinishing统计

我有一个popUpWindow需要显示,几秒后如果 用户仍然处于当前活动状态。我执行了声明,检查是否 活动没有完成/销毁,然后显示弹出窗口,它工作 很好,适合周末用户:)(慢慢地从活动点击活动),但在 高压测试(活动正在重现,完成,快速移动的形式 ACTI虚度去活动),这给了我一个错误:

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);
还请确保您通过ActivityName.this作为上下文..而不是getApplicationContext() 试试看将您的runnable代码置于showPopUpWindow()中:
runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if (!isFinishing()) {
                popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER, 0, 0);
            }
        }
    });

代替

if(!context.isFinishing())
尝试
if(!((Activity) context).isFinishing())
为我工作得很好。
