我正在尝试在一个片段中添加TabHost ......以下是代码。在此片段中,我尝试添加TabHost以显示两个选项卡。
public class TablesFragment extends Fragment {
TabHost tabHost;
TabHost.TabSpec spec;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tables_fragment, container,
false);
tabHost = (TabHost) rootView.findViewById(android.R.id.tabhost);
tabHost.setup();
Intent intentAndroid = new Intent().setClass(getActivity(),
NewsFragment.class);
spec = tabHost.newTabSpec("Android").setContent(intentAndroid)
.setIndicator("Android");
tabHost.addTab(spec);
Intent intentBus = new Intent().setClass(getActivity(), NewsFragment.class);
spec = tabHost.newTabSpec("Welcome").setIndicator("Welcome")
.setContent(intentBus).setIndicator("Welcome");
tabHost.addTab(spec);
return rootView;
}
这个代码给我报错了...需要帮助...
