you must use style dialog. example create my_dialog_style.xml in values res folder:

<?xml version="1.0" encoding="utf-8"?> <resources>     <style name="mydialogstyle" parent="@android:style/theme.dialog">         <item name="android:textcolor">#ff000000</item>         <item name="android:textsize">16sp</item>     </style> </resources> 

and apply dialog:

alertdialog.builder builder = new alertdialog.builder(new contextthemewrapper(this, r.style.mydialogstyle)); 

one way set gravity of text use this:

textview messagetext = (textview) alertdialog.findviewbyid(android.r.id.message);         messagetext.setgravity(gravity.center);
