(AppCompat) 没有 UI 的活动

Question

As per this post , I know I am allowed to create an activity that has no user interface by declaring your activity like below:

<activity
    android:name=".NoUIActivity"
    android:theme="@android:style/Theme.NoDisplay">
</activity>

My problem is NoUIActivity extends AppCompatActivity. If I use the android:theme line above, it gives me error saying I should use the corresponding AppCompat theme. Help please. Thanks!

Answer 1

1. Create an app with single activity
2. Delete the layout xml which you don't need
3. Remove setContentView line (generated by Android Studio),in Activity's onCreate() method
4. Call finish() when done
