Question

I have a button that starts out as a placeholder, but once the user authenticates, it changes to a custom image for that user.

<ImageButton android:id="@+id/button"
             android:background="@null"
             android:layout_height="wrap_content"
             android:layout_width="wrap_content"
             android:src="@drawable/button_default"/>

And then later:

ImageButton ib = (ImageButton)findViewById(R.id.button);
ib.setImageBitmap(previouslyDecodedBitmap);

But this looks terrible. I can’t figure out how to style it properly so that the newly decoded bitmap is the right size and behaves like an ImageButton. I suspect there is some combination of widgets I can use other than ImageButton to achieve this? I was hoping I could just nest an ImageView on top of the ImageButton by adding it as a child to ImageButton, but that doesn’t seem to be allowed (it is in Silverlight…).

Anyway, any suggestions on how to properly do this are welcome. Thanks.

One way would be to use frame layout and place buttons and image one over the other , top being imageview , keep it invisible (android:visibility = “invisible”)
On clicking the button and authenticating , make it visible over the button or else even you can hide the button below and show only image on top.
