android - TabSpec SetContent fragment

我在Fragment中使用TabHost来创建选项卡。我遇到的问题是TabSpec的setContent()。我需要对其进行设置，以使其在<FrameLayout>下嵌套另一个片段。

我是否使用getChildFragmentManager()来做到这一点？我该怎么做？

Xml布局：

<LinearLayout android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical"
        >

    <TabWidget android:id="@android:id/tabs"
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:layout_weight="0"
               android:orientation="horizontal"
            />

    <FrameLayout android:id="@android:id/tabcontent"
                 android:layout_width="match_parent"
                 android:layout_height="0dp"/>

    <FrameLayout android:id="@+id/following"
                 android:layout_width="fill_parent"
                 android:layout_height="fill_parent"/>

    <FrameLayout android:id="@+id/you"
                 android:layout_width="fill_parent"
                 android:layout_height="fill_parent"/>

</LinearLayout>

片段类：

public class ActivityFragment extends Fragment implements TabHost.OnTabChangeListener {
private static final String FOLLOWING_SPEC = "following";
private static final String YOU_SPEC = "you";

private TabHost tabHost;

public ActivityFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_activity, container, false);

    tabHost = (TabHost)view.findViewById(android.R.id.tabhost);
    tabHost.setup();

    TabHost.TabSpec followingSpec = tabHost.newTabSpec(FOLLOWING_SPEC);
    followingSpec.setIndicator("Following");
    followingSpec.setContent(); // <===Need to set content to fragment

    TabHost.TabSpec youSpec = tabHost.newTabSpec(YOU_SPEC);
    youSpec.setIndicator("You");

    tabHost.addTab(followingSpec);
    tabHost.addTab(youSpec);
    tabHost.setCurrentTab(0);

    return view;
}

@Override
public void onTabChanged(String s) {

    }
}

最佳答案

这就是答案。我在混合android的TabHost和支持库的FragmentTabHost。两件事！

public class ActivityFragment extends Fragment implements TabHost.OnTabChangeListener {
private static final String FOLLOWING_SPEC = "following";
private static final String YOU_SPEC = "you";

private FragmentTabHost tabHost;

public ActivityFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_activity, container, false);

    tabHost = (FragmentTabHost)view.findViewById(R.id.tabhost);
    tabHost.setup(getActivity(), getChildFragmentManager(), android.R.id.tabcontent);

    tabHost.addTab(tabHost.newTabSpec(FOLLOWING_SPEC).setIndicator("Following"), FollowingActivityFragment.class, null);
    tabHost.addTab(tabHost.newTabSpec(YOU_SPEC).setIndicator("You"), YouActivityFragment.class, null);
    tabHost.setCurrentTab(0);

    return view;
}



 @Override
    public void onTabChanged(String s) {

    }
}
