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);
mapView is a MapView and nothing is null. The stacktrace:
01-08 18:00:09.402: E/AndroidRuntime(27768): Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running?

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);
}
Thank you for sharing your thoughts
This question is related to
android
There are two scenarios when this exception could occur. One is mentioned by nandeesh. Other scenario is mentioned here: http://blackriver.to/2012/08/android-annoying-exception-unable-to-add-window-is-your-activity-running/
Make sure you handle both of them
try to show popup like this
new Handler().postDelayed(new Runnable(){
public void run() {
popupWindow.showAtLocation(context.getWindow().getDecorView(), Gravity.CENTER,0,0);
}
}, 200L);
Try to use it
LayoutInflater inflater = (LayoutInflater).getApplicationContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View view = inflate.from(YourActivity.this).inflate(R.layout.yourLayout, null);
A popup's parent can't itself be a popup. Both of their parents must be the same. So, if you create a popup inside a popup, you must save the parent's popup and make it a parent.
here's an example
Try to show the pop like below
findViewById(R.id.main_layout).post(new Runnable() {
public void run() {
mPopupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.CENTER, 0, 0);
Button close = (Button) customView.findViewById(R.id.btn_ok);
close.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mPopupWindow.dismiss();
doOtherStuff();
}
});
}
});
@Override
protected void onCreate(Bundle savedInstanceState) {
View view = LayoutInflater.from(mContext).inflate(R.layout.popup_window_layout, new LinearLayout(mContext), true);
popupWindow = new PopupWindow(view, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setContentView(view);
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
if (hasFocus) {
popupWindow.showAtLocation(parentView, Gravity.BOTTOM, 0, 0);
}
}
the correct way is popupwindow.show() at onWindowFocusChanged().
Following many hours of search and testing i found following solution(by implementing different SO solutions) here it what didn't failed in any case i was getting crash.
Runnable runnable = new Runnable() {
@Override
public void run() {
//displayPopup,progress dialog or what ever action. example
ProgressDialogBox.setProgressBar(Constants.LOADING,youractivityName.this);
}};
Where logcat is indicating the crash is happening.. start a runnable .in my case at receiving broadcast.
runOnUiThread(new Runnable() {
@Override
public void run() {
if(!isFinishing()) {
new Handler().postAtTime(runnable,2000);
}
}
});
Same problem happened with me when i try to show popup menu in activity i also got same excpetion but i encounter problem n resolve by providing context
YourActivityName.this
instead of getApplicationContext()
at
Dialog dialog = new Dialog(getApplicationContext());
and yes it worked for me may it will help someone else
Use:
YourActivityName.this
Instead of:
getApplicationContext();
use this method before show
public static ViewGroup getActivityFirstLayout(Context ctx)
{
return (ViewGroup)((ViewGroup) ActivityMaster.getActivity(ctx).findViewById(android.R.id.content)).getChildAt(0);
}
private boolean activityIsOk(Activity activity)
{
boolean s1 = !(activity == null || activity.isFinishing());
if(s1)
{
View v = LayoutMaster.getActivityFirstLayout(activity);
return v.isShown() && ViewCompat.isLaidOut(v);
}
return false;
}
