如果用户仍在当前活动中,我有一个需要在几秒钟后显示的弹出窗口。我实现了一个语句,检查活动是否未完成/销毁,然后显示弹出窗口,对于周末用户来说,它工作得很好:)(从一个活动缓慢单击到另一个活动),但在高压测试中(活动正在重新创建、完成、快速移动形式)活动到活动)这给了我这个错误:
E/UncaughtException:android.view.WindowManager$BadTokenException:
无法添加窗口——token null 无效;是你的活动
跑步?

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);
还要确保你通过ActivityName.this
作为上下文..不getApplicationContext
()
尝试更换你的runnable
代码在showPopUpWindow()
有了这个:
runOnUiThread(new Runnable() {
@Override
public void run() {
if (!isFinishing()) {
popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER, 0, 0);
}
}
});
