이 탭은 잘 만들 추가하지만, 아무것도 보여줍니다 ExpandableListViewActivity를 데리고 오늘 탭을 클릭하면 쪽으로. Tab.axml의 LinearLayout을 Relative로 변경 한 다음 ExpandableListView가 나타나지만 첫 번째 항목이 오늘 탭 상단에 있고 항목을 확장하려고 시도하면 앱이 다운됩니다.

앱 Tab.axml가 RelativeLayout의

Answer 1

가 작동 할 때 가지고있는 LinearLayout Tab.axml는

애플리케이션을 가질 때. 해결 방법은 상대적 레이아웃을 사용하여 Tab.axml을 그대로두고 FrameLayout을 TabWidget 아래에 지정하는 것입니다.

<FrameLayout 
android:id="@android:id/tabcontent" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:layout_below="@android:id/tabs"> 
</FrameLayout>
