Android Alertdialog Box Windowmanager$badtokenexception Problem

I am using the the following code for a context menu and then if user chose delete, a dialog massage will appear. infos.setOnCreateContextMenuListener(new OnCreateContextMenuListen

Solution 1:

I believe the problem could be on this line:

AlertDialog.Builderbuilder=newAlertDialog.Builder(this);

Try modifying it to:

AlertDialog.Builderbuilder=newAlertDialog.Builder(MyActivityName.this);

Replacing MyActivityName with the name of your activity.

Did that fix the error?

Solution 2:

It should be AlertDialog.Builder builder = new AlertDialog.Builder(this.getParent());

Because the activity is in a tabactivity within another tabactivity.

Solution 3:

I was getting the same error. I changed

AlertDialog.Builderbuilder=newAlertDialog.Builder(this);

to

 AlertDialog.Builderbuilder=newAlertDialog.Builder(MainActivity.this);

Its working fine now. Thanks.

Solution 4:

Kotlin

Change from this:

val builder: AlertDialog.Builder = AlertDialog.Builder(this)

to

val builder: AlertDialog.Builder = AlertDialog.Builder(this@MainActivity)
