Adding Custom Background for Widget Based on User Input

Question

I have a widget that displays a set of information. What I would like to do is to give the user the opportunity to choose the background color/image. I would like to have a popup when the user is selecting the widget to choose the background.

So how would I make the popup?

And how would I apply the background dynamically?

Thank you for any help you can give!!

Answer 1

I haven't done this specifically before but I would go about it in the following manner:

• If you are looking to pick up files that are already on the system, fire an intent to pick (ACTION_PICK) and supply the right Intent.data element
• If you are supplying the options:
  • Create a Dialog with a list view (of image view / text view (with compound drawables and some text)) to select the background
  • Store the value returned into a preference file
  • Read from preference and apply Background

Hope this helps
