Android - Dialog onResume？

Question

I have an action that takes place in Dialog . That action starts another app which results I get in onActivityResult in the Activity . Now, I want special "something" to happen when the results are received, but in the Dialog . Is there something like onResume or onActivityResult but for dialogs?

Answer 1

Yes. You can create an Activity and give it a Dialog theme. It'll work just like an Activity, but look like a dialog.

Just add this

<activity android:theme="@android:style/Theme.Dialog" />

If you don't want to go this route you can also use Message Handlers. That way you can pump message to where ever from where ever.

Answer 2

You could wrap your Dialog in an Activity , create a variable to house your Dialog , then in onCreate() for the Activity , build the actual Dialog and show() it. When the Activity receives the results, it could reference the Dialog by the variable name and call any necessary methods.
