Error in app theme

Question

Guys I implemented some tabs in the app I’m developing with Fragments and had to use the theme of Appcompat but started giving this error:

Caused by: java.lang.Illegalstateexception: You need to use a Theme.Appcompat Theme (or Descendant) with this Activity.

Ai vou la na manifest e troco pro Appcompat, but then no more my actionbar appears in the app.

With Theme.Holo.Light the actionbar appears, but if I change because of the error it disappears.

And now?

Does anyone have any idea?

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

Answer 1

To Activity that you’re trying to use the ActionBar class extension ActionBarActivity, in this case it is mandatory that you use the theme of AppCompat.

Make your class extend Activity Activity and leave the theme Theme.Holo.Light that will probably work.

@Edit

If you want to continue using the AppCompat, use a descending theme of Theme.AppCompat, Theme.AppCompat.Light or Theme.AppCompat.Light.DarkActionBar
