How do we know how exactly user cancelled the dialog?

Question

I use a cancellable dialog fragment with setCanceledOnTouchOutside(true). Now I want to distinguish two cases:

• user cancels the dialog using Back button;
• user cancels the dialog by touching outside of it.

Both actions lead to invocation of both onCancel() and onDismiss() listeners. Also these two listeners accept DialogInterface as a parameter, to there no any "event state" to check how exactly user has cancelled the dialog.

So what can I do?

Answer 1

To know if the user has pressed the back button of the device, override the method onBackPressed:

@Override
public void onBackPressed()
{
 //here you could set a boolean to know if the user pressed the back button, and react accordingly when the dialog is closed.
backPressed=true;
}

For example.
