在Fragment中添加选项卡的Android实现

androidtabsfragment
7

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...

我知道这已经过去将近一年了，但是使用针对API17的v22兼容库并使用TabLayout，我已经能够在顶层活动中添加选项卡，为每个选项卡添加片段，然后向这些片段添加TabLayout并获取第二级选项卡并添加片段（嵌套）。当将子片段添加到片段时，必须使用getChildFragmentManager。我会把这个作为答案提交，但我没有代码示例，最终可能会被踩。 - BK-

我相信如果你的目标是API17+，这对你可能有用。 否则，你应该看一下ViewContainers和可滑动视图。

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTabHost;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class TabHostParentFragment extends Fragment {

private FragmentTabHost tabHost;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
tabHost = new FragmentTabHost(getActivity());
tabHost.setup(getActivity(), getChildFragmentManager(), R.layout.my_parent_fragment);

Bundle arg1 = new Bundle();
arg1.putInt("Arg for Frag1", 1);
tabHost.addTab(tabHost.newTabSpec("Tab1").setIndicator("Frag Tab1"),
    NewsFragment.class, arg1);

Bundle arg2 = new Bundle();
arg2.putInt("Arg for Frag2", 2);
tabHost.addTab(tabHost.newTabSpec("Tab2").setIndicator("Frag Tab2"),
    MyNestedFragment2.class, arg2);

return tabHost;
}

公共类 MainActivity 扩展了 FragmentActivity 并实现了 TabHost.OnTabChangeListener 接口 - MKDenys
编辑了我的答案，我相信其中一个应该可以解决问题，无论您是否使用API 17。 - chriskvik
谢谢！花了五个小时寻找解决这个问题的方案。 - MKDenys

@CantThinkOfAnything 是的，你可以通过编程使用SimpleGestureListener使它们可滑动。 - chriskvik

请查看下面的代码，如果您仍在寻找答案，它一定会帮助您，并且它将适用于旧版本的API 11。

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AnalogClock;
import android.widget.TabHost;

public class TabFragment extends Fragment {

    private TabHost mTabHost;
    View rootView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        rootView = inflater.inflate(R.layout.tabinterview, container, false);
        mTabHost = (TabHost) rootView.findViewById(R.id.tabhost);
        mTabHost.setup();
        TabHost.TabSpec spec = mTabHost.newTabSpec("tag");
        spec.setIndicator("Android");
        spec.setContent(new TabHost.TabContentFactory() {

            @Override
            public View createTabContent(String tag) {
                // TODO Auto-generated method stub
                return (new AnalogClock(getActivity()));
            }
        });
        mTabHost.addTab(spec);
        spec = mTabHost.newTabSpec("tag1");
        spec.setIndicator("java");
        spec.setContent(new TabHost.TabContentFactory() {

            @Override

            }
        });
        mTabHost.addTab(spec);
        spec = mTabHost.newTabSpec("tag2");
        spec.setIndicator("Favourate");
        spec.setContent(new TabHost.TabContentFactory() {

            @Override

如果您使用的是：https://dev59.com/WXvaa4cB1Zd3GeqPHcI_#34224495

请确保布局如下：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".view.user.DetailsFragment">

<TabHost
    android:id="@+id/tabhost"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <TabWidget
        android:id="@android:id/tabs"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent">
    </TabWidget>

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