选项卡内容未在FragmentTabHost Android上显示

我尝试过使用FragmentTabHost。一切都进行得很顺利，并且成功地显示了选项卡。但我的片段没有显示那个类的布局。我尝试过使用TextView，但仍然没有出现。 请帮帮我

我的零碎活动

public class ViewDetailAnak extends FragmentActivity{

private static String idanak;

private FragmentTabHost tabHost;
private static final String TRANS_SPEC = "";
private static final String US_SPEC = "";
private static final String TABU_SPEC =  "";

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fro_single_item_anak);


      tabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
      tabHost.setup(this, getSupportFragmentManager(),android.R.id.tabcontent);

        tabHost.addTab(
                tabHost.newTabSpec(TRANS_SPEC)
                .setIndicator(TRANS_SPEC, getResources().getDrawable(R.drawable.icon_trans)),
                FROVDATransaksi.class, null);
        tabHost.addTab(
                tabHost.newTabSpec(US_SPEC)
                .setIndicator(US_SPEC, getResources().getDrawable(R.drawable.icon_us)),
                FROVDAUangsaku.class, null);
        tabHost.addTab(
                tabHost.newTabSpec(TABU_SPEC)
                .setIndicator(TABU_SPEC, getResources().getDrawable(R.drawable.icon_tab)),
                FROVDATabungan.class, null);
}

三块碎片中的一块

 public static class FROVDAUangsaku extends Fragment {
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
 }

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                           Bundle savedInstanceState) {
     View v = inflater.inflate(R.layout.fro_vda_uangsaku, container, false);
     return v;


}
   }

忽略内部表格布局。唯一的设计。我在TableLayout下创建fragmenttab
