You need to use a Theme.AppCompat theme (or descendant) with this activity. Change to Theme.AppCompat causes other error

Question

I use appcompat v22.1.0 in my App and use Toolbar. Everything was fine when I use Theme.AppCompat.Light.NoActionBar. When I start implement AlertDialog

Answer 1

if you have this error when you creating a dialog (just in my case) you should use the following:

AlertDialog.Builder dialog = new AlertDialog.Builder(context, R.style.Theme_AppCompat_Light);

instead of:

AlertDialog.Builder dialog = new AlertDialog.Builder(context);

This worked me perfectly!
