The reason you are having this problem is because the activity you are trying to apply the dialog theme to is extending ActionBarActivity which requires the AppCompat theme to be applied.

Change the Java inheritance from ActionBarActivity to Activity and leave the dialog theme in the manifest as it is.

一句话：ActionBarActivity 改成Activity 。
