Answer 1

If getParent() doesn't work for you, try using just TabsActivity.context (or substitute the name of your parent tab activity class). I am using nested activities and as a result using getParent() is still not returning the right context for the dialog, since it needs the context of the activity extending TabsActivity, not the immediate parent.

Simple fix:

1. You'll need to create a context variable in the TabsActivity class. Something like public static TabsActivity context; and context=this in the onCreate method.

2. Replace this line where you create the dialog:

   AlertDialog.Builder builder = new AlertDialog.Builder(this);

With:

AlertDialog.Builder builder = new AlertDialog.Builder(TabsActivity.context); 

and it works like a charm.

Simple here you can also use following

private final ProgressDialog dialog = new ProgressDialog(getParent());

it work perfectly for me .

Answer 3

If the ActivityGroup is within a TabActivity you have nested activities with more then two levels. Android doesn't support this at the moment but there is a workaround. You have to pass the parent activity to the dialog.

Create a helper method for this purpose in the activity class:

private Context getDialogContext() {
    Context context;
    if (getParent() != null) context = getParent();
    else context = this;
    return context;
}

Then change the line

private final ProgressDialog dialog = new ProgressDialog(CheckInActivity.this);

to

private final ProgressDialog dialog = new ProgressDialog(getDialogContext());
