Answer 1

It is probably because you are running your app on Android 5.0+ which has Material design.

To get the "old" look, just construct your dialog with the Holo style:

ContextThemeWrapper themedContext = new ContextThemeWrapper(getContext(), android.R.style.Theme_Holo_Light_Dialog_NoActionBar);
AlertDialog.Builder builder = new AlertDialog.Builder(themedContext);
// ... then create your dialog

Although this might seem weird for some users (especially on Lollipop and Marshmallow, so I recommend looking into using custom views for your dialog.
