Your Content Must Have A Tabhost Whose Id Attribute Is 'android.r.id.tabhost'

I have a problem: Java Code public class VisualizzaListaActivity extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle saved

Solution 1:

I believe the message means this:

     <TabHost android:id="@+id/tabhost"

should be changed to:

     <TabHost android:id="@android:id/tabhost"

Solution 2:

Try cleaning your build from the Project > Clean... menu if you are using Eclipse. Sounds simple but often fixes this problem.

Solution 3:

Only thing you need to change is android:id attribute in layout xml , It should be " android:id="@android:id/tabhost" "

Solution 4:

I had the same problem. Actually I extended TabActivity for DaAcquistareActivity class. This was the reason. I solved the problem by extending DaAcquistareActivity with Activity and not with TabActivity.

Solution 5:

Solution. If you're switching to a new Activity check it extends, perhaps on reflex copied from the primary, and there is a TabActivity, but we need Activity or other activity.
