PopupWindow $ BadTokenException：无法添加窗口 - 标记空是无效的 [英] PopupWindow $BadTokenException: Unable to add window -- token null is not valid

问题描述

显示PopupWindow时，我有以下错误。 该错误是由该行触发：

I have the following error when showing a PopupWindow. The errors are triggered by the line:

checkInPopup.showAtLocation((ViewGroup) mapView.getParent(), Gravity.CENTER_HORIZONTAL, 0, 0);

图形页面是一个图形窗口和没有什么是零。 该堆栈跟踪：

mapView is a MapView and nothing is null. The stacktrace:

这是从我的活动code（扩展MapActivity）

This is the code from my activity (that extends MapActivity)

    protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.checkin);
    mapView = (MapView) findViewById(R.id.mapview);

    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    checkInPopup = new PopupWindow(inflater.inflate(CHECK_IN_POPUP_LAYOUT, null, false));
    checkInPopup.setOutsideTouchable(true);
    checkInPopup.setHeight(100);
    checkInPopup.setWidth(200);
    checkInPopup.showAtLocation((ViewGroup) mapView.getParent(), Gravity.CENTER_HORIZONTAL, 0, 0);
}

推荐答案

你是显示太早弹出式窗口。您可以张贴一个可运行的延迟为showatlocation在Onresume，试试看吧。

you are showing your popup too early. You may post a delayed runnable for showatlocation in Onresume , Give it a try
