android - Overlay an activity on another activity OR overlay a view over another

Question

I have 2 classes, FirstActivity and SecondActivity.

First Activity

Intent intent=new Intent(getApplicationContext(),SecondActivity.class);
startActivity(intent);

Is it possible for SecondActivity to overlay on FirstActivity? ie. FirstActivity gets dimmed, SecondActivity gets displayed on top of FirstActivity.

If it is not possible for 2 different activities, is it possible to do an overlay for 2 views in the same activity? I hope using dialog is not the only option.

Answer 1

I suggest you set your second activity up as a dialog -- which will dim the background. Here is a tutorial that could be helpful:

Or you can simply set the theme in the manifest as a dialog for your SecondActivity.
