There are several options. You can use a theme and make an activity look and behave like a dialog (as in this question) by setting the android:theme attribute of your <activity> to @android:style/Theme.Dialog or a customized theme in your manifest.

Alternatively, you could create a translucent activity by setting the theme to @android:style/Theme.Translucent.NoTitleBar and then launch a regular dialog from the activity. As the comments on one of the answers to the question advise, in this case just make sure to finish() the translucent activity whenever the dialog is dismissed.
