Question

我有一个带按钮的PopupWindow。在我点击我想要显示ListPopupWindow的按钮，但我得到

FATAL EXCEPTION: main
android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@439c79f0 is not valid; is your activity running?

这是我的show（）方法，名为onClick（）。我在最后一行得到了错误

popup.show();

全：

void showList(View view){

    final ListPopupWindow popup = new ListPopupWindow(this);
    popup.setAdapter(new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, Category));
    popup.setAnchorView(view);
    popup.setWidth(ListPopupWindow.WRAP_CONTENT);
    popup.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {
            tvCategory.setText(Category[position]);
            popup.dismiss();
        }
    });

    popup.show();


}

    popup.show();


}


@Override
public void onMapReady(GoogleMap map) {

// map.addMarker（new MarkerOptions（）。position（new LatLng（0,0））。title（“Marker”））; map.setMapType（MAP_TYPE_TERRAIN）; }

}

Answer 1

更改final ListPopupWindow popup = new ListPopupWindow(this); 至 final ListPopupWindow popup = new ListPopupWindow(MapSights.this);

尝试在致电popup.show();之前检查活动是否完成，以避免错误您的活动是否正在运行？

if(!isFinishing()) {
    popup.show();
}

从PopWindow中显示ListPopupWindow
