我有一个从片段调用的PopupWindow,除了我的Spinner,一切都有效.当我点击我的Spinner时它会崩溃并给出错误：
“android.view.WindowManager $BadTokenException：无法添加窗口 – 令牌android.view.ViewRootImpl$W@421a46d8无效;您的活动是否在运行？”
我的代码调用片段中的弹出窗口：
ManagerPopUp mManagerPopUp = new ManagerPopUp(getActivity()); mManagerPopUp.showPopUpAddEvent();
public class ManagerPopUp {
private static final String TAG = "PopUpManager";
private Context mContext;
public ManagerPopUp(Context mContext){
this.mContext = mContext;
}
public PopupWindow showPopUpAddEvent(){
final PopupWindow popUp = new PopupWindow(mContext);
LayoutInflater inflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.popup_add_event,null);
//Code for popup event
TextView txtRoom,txtTitle,txtEnd,txtStart;
ToggleButton tgRepeateWeekly,tgAddReminder;
Button btConfirme,btCancel;
txtTitle = (TextView)layout.findViewById(R.id.txt_lesson_title_event);
txtRoom = (TextView)layout.findViewById(R.id.txt_lesson_room_event);
txtStart = (TextView)layout.findViewById(R.id.txt_lesson_start_hour_event);
txtEnd = (TextView)layout.findViewById(R.id.txt_lesson_end_hour_event);
final Spinner spSelectCalendar = (Spinner)layout.findViewById(R.id.sp_select_calendar);
Spinner spSelectReminder = (Spinner)layout.findViewById(R.id.sp_select_reminder_time);
tgRepeateWeekly = (ToggleButton)layout.findViewById(R.id.tg_repeate_weekly);
tgAddReminder = (ToggleButton)layout.findViewById(R.id.tg_add_reminder);
btConfirme = (Button)layout.findViewById(R.id.bt_confirme);
btCancel = (Button)layout.findViewById(R.id.bt_cancel);

HandlerCalendarProvider mCalendarProvider = new HandlerCalendarProvider(mContext);
final ArrayList<ClassCalendar> mCalendarsList = mCalendarProvider.getAllCalendars();
AdapterCalendarSpinner mAdapterCalendarSpinner =
new AdapterCalendarSpinner(mContext,mCalendarsList);
spSelectCalendar.setAdapter(mAdapterCalendarSpinner);
popUp.setContentView(layout);
popUp.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);
popUp.setHeight(LinearLayout.LayoutParams.MATCH_PARENT);
popUp.setFocusable(true);
// Some offset to align the popup a bit to the left,and a bit down,relative to button's position.
popUp.setBackgroundDrawable(new BitmapDrawable(mContext.getResources(),BitmapFactory.decodeResource(mContext.getResources(),R.color.color_popup_background))); //PopUpBackground
popUp.showAtLocation(layout,Gravity.NO_GRAVITY,0);
return popUp;
}
}
我的微调适配器：
public class AdapterCalendarSpinner extends BaseAdapter implements SpinnerAdapter {
private Context mContext;
private ArrayList<ClassCalendar> mCalendarsList;
public AdapterCalendarSpinner(Context mContext,ArrayList<ClassCalendar> mCalendarsList) {
this.mContext = mContext;
this.mCalendarsList = mCalendarsList;
}
@Override
public int getCount() {
return mCalendarsList.size();
}
@Override
public ClassCalendar getItem(int position) {
return mCalendarsList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position,View convertView,ViewGroup parent) {
ClassCalendar o = mCalendarsList.get(position);
LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.sp_item_calendar_selected,null);
LinearLayout llCalColor = (LinearLayout)convertView.findViewById(R.id.ll_calendar_selected_color);
TextView txtCalName = (TextView)convertView.findViewById(R.id.txt_calendar_selected_name);
TextView txtCalEmail = (TextView)convertView.findViewById(R.id.txt_calendar_selected_email);
llCalColor.setBackgroundColor(o.getCalColor());
txtCalName.setText(o.getCalName());
txtCalEmail.setText(o.getCalEmail());
txtCalName.setTextColor(Color.WHITE);
txtCalEmail.setTextColor(Color.WHITE);
return convertView;
}
@Override
public View getDropDownView(int position,ViewGroup parent) {
ClassCalendar o = mCalendarsList.get(position);
LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.sp_item_calendar,null);
//convertView = LayoutInflater.from(mContext).inflate(R.layout.sp_item_calendar,null);
LinearLayout llCalColor = (LinearLayout)convertView.findViewById(R.id.ll_calendar_color);
TextView txtCalName = (TextView)convertView.findViewById(R.id.txt_calendar_name);
TextView txtCalEmail = (TextView)convertView.findViewById(R.id.txt_calendar_email);
llCalColor.setBackgroundColor(o.getCalColor());
txtCalName.setText(o.getCalName());
txtCalEmail.setText(o.getCalEmail());
return convertView;
}
}
