using the idea from a google group post I was able to pull it off styling an activity. you would want to modify the height and width to a “dynamic” size of your choice preferably. Then set whatever ActionBar buttons you would like
<style name="PopupTheme" parent="android:Theme.Holo.Light.Dialog">
<item name="android:windowIsFloating">false</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowSoftInputMode">stateAlwaysHidden</item>
<item name="android:windowActionModeOverlay">true</item>
<item name="android:windowIsTranslucent">true</item>
</style>
—
public static void showAsPopup(Activity activity) {
//To show activity as dialog and dim the background, you need to declare android:theme="@style/PopupTheme" on for the chosen activity on the manifest
activity.requestWindowFeature(Window.FEATURE_ACTION_BAR);
activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND,
WindowManager.LayoutParams.FLAG_DIM_BEHIND);
LayoutParams params = activity.getWindow().getAttributes();
params.height = 850; //fixed height
params.width = 850; //fixed width
params.alpha = 1.0f;
params.dimAmount = 0.5f;
activity.getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
setContentView(R.layout.activity_main);
}
