“您需要使用Theme.AppCompat主题”

Question

I'm programming an application on android, and I've a little problem : I would like to make a customiz Dialog box so I do like in the android documentation :

In my manifest :

 <application android:allowBackup="true" android:icon="@drawable/indice" android:label="33" android:theme="@style/AppTheme"> <activity android:name=".Autres.Indice" android:theme="@android:style/Theme.Holo.Dialog"> </activity> 

In style :

 <style name = "AppTheme" parent="@style/Theme.AppCompat.NoActionBar"> </style> 

But when I run : Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

I don't understand, thank's^^

Answer 1

You are having this issue because the activity you are trying to apply the dialog theme to is not extending Activity , that requires AppCompat theme.

Change

    android:theme="@style/AppTheme">

For

    android:theme="@style/Theme.AppCompat" />
