我试试这段代码：

                        android:layout_width="fill_parent"

                        android:layout_height="wrap_content"
                        android:divider="#b5b5b5"
                        android:dividerHeight="1dp"
                        android:listSelector="@drawable/list_selector" />
                </LinearLayout>
            </FrameLayout>
        </LinearLayout>
    </TabHost>
</LinearLayout>

并使用此代码处理我的片段类

中的tab主机

 public class HostFragment extends Fragment {
private FragmentTabHost mTabHost;

public HostFragment() {
    // Empty constructor required for fragment subclasses
}

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_host_layout,
            container, false);

    setHasOptionsMenu(true);
     TabHost mTabHost = (TabHost) rootView.findViewById(R.id.tabhost);

         mTabHost.setup( );
     TabSpec photospec = mTabHost.newTabSpec("Search");
     photospec.setIndicator("Search",
     getResources().getDrawable(R.drawable.action_search));
     Intent searchIntent = new Intent(getActivity(),
     HostViewIntroduce.class);
     photospec.setContent(searchIntent);

     TabSpec songspec = mTabHost.newTabSpec("Favorites");
     songspec.setIndicator("Favorites",
     getResources().getDrawable(R.drawable.action_search));
     Intent favoriteIntent = new Intent(getActivity(),
     HostViewTips.class);
     songspec.setContent(favoriteIntent);

 mTabHost.addTab(songspec);
 mTabHost.addTab(photospec);

    return rootView;

}

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    return super.onOptionsItemSelected(item);
}

 }

并抛出nullpointer异常

01-09 13:40:31.781: E/AndroidRuntime(5871): FATAL EXCEPTION: main
01-09 13:40:31.781:   E/AndroidRuntime(5871): java.lang.IllegalStateException: Did you forget to call 'public void    setup(LocalActivityManager activityGroup)'?

Answer 1

您需要使用 FragmentTabHost 的自定义 addTab（） ，这也会将您的Fragment类视为参数。

替换

 TabSpec photospec = mTabHost.newTabSpec("Search");
 photospec.setIndicator("Search",
 getResources().getDrawable(R.drawable.action_search));
 Intent searchIntent = new Intent(getActivity(),
 HostViewIntroduce.class);
 photospec.setContent(searchIntent);

 TabSpec songspec = mTabHost.newTabSpec("Favorites");
 songspec.setIndicator("Favorites",
 getResources().getDrawable(R.drawable.action_search));
 Intent favoriteIntent = new Intent(getActivity(),
 HostViewTips.class);
 songspec.setContent(favoriteIntent);

与

  TabHost.TabSpec photospec = mTabHost.newTabSpec("Search");
  photospec.setIndicator("Search",
  getResources().getDrawable(R.drawable.action_search));
  photospec.setIndicator(rootView);
  mTabHost.addTab(photospec, HostViewIntroduce.class, null);


  TabSpec songspec = mTabHost.newTabSpec("Favorites");
  songspec.setIndicator("Favorites",
  getResources().getDrawable(R.drawable.action_search));
  songspec.setIndicator(rootView);
  mTabHost.addTab(songspec, HostViewTips.class, null);

将tabhost放入片段中？
