问题与您需要与此活动一起使用Theme.AppCompat主题（或后代）与该活动一起Theme.AppCompat主题（或后代）”

Question

I am suddenly getting this issue. I have gone through a number of the posts on this site and others. Here are a few of the links I have visited in my attempts to understand the cause of this problem;

• [ https://teamtreehouse.com/community/need-to-use-a-themeappcompat-theme-or-descendant-with-this-activity]

• [ ActionBarCompat: java.lang.IllegalStateException: You need to use a Theme.AppCompat

• [ .IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity

From what I can tell the reason for this error has been different in each of these cases. I have posted my logicat snippet below.

Not sure exactly how to fix this. I have gone through the articles listed above and tried the solutions that were provided without no much success. I have also tried changing the theme directly on the layout designer directly on the layout. Any sort of assistance on fixing this would be appreciated.

Answer 1

So since the comment I posted worked for you, I decided to post ehr solution here in order to give it more visibility and help other users.

SOLUTION

Hou have to set the theme to your BowlerActivity in your Manifest .

<activity 
   androidd:name=".views.BowlerActivity" 
   android:theme="@style/AppTheme" />
