I try to show a dialog in my Activity and I get this error : "You need to use a Theme.AppCompat theme"
There are lots of question/answers about this, but I don't get it in my situation: Can someone help me ? I know it has something to do with the app theme, but I think this is ok in my situation. Can please someone take a look:

My Activity is extending Activity
public class ChronicBrowser extends Activity {
Make the activity extend AppCompatActivity
instead.
Most of the AppCompat stuff requires AppCompat classes, for an instance AppCompatActiviity or the fragment import from the support package i stead
尝试在清单的活动标签中添加android:theme =“ @ style / AppTheme”。
