Android 在 Fragment 中添加选项卡

【中文标题】Android 在 Fragment 中添加选项卡

【英文标题】：Android Adding Tab inside Fragment

【发布时间】：2014-02-17 07:55:05

【问题描述】：

我正在尝试在片段中添加 TabHost ...代码如下所示。在片段中我正在尝试添加 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;

这给了我错误...需要此代码的助手...

【问题讨论】：

我知道这已经快一年了，但是使用针对 API17 的 v22 兼容库，并使用 TabLayout，我已经能够在***活动上添加选项卡，向每个选项卡添加片段，然后将 TabLayout 添加到这些片段并获得第二级选项卡并将片段添加到那些（嵌套）。将子片段添加到片段时必须使用getChildFragmentManager。我会将此作为答案提交，但我没有代码示例，我最终会被否决..

【参考方案1】：

如果您的目标是 API17 +，我相信这对您有用。 如果没有，你应该看看ViewContainers, and swipeable views。

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;

【讨论】：

公共类 MainActivity 扩展 FragmentActivity 实现 TabHost.OnTabChangeListener

啊，我的错。您是否尝试在 MainActivity 视图中有一个“主”选项卡？或者片段控制器内部的选项卡控制器，用于其中一个片段内部的选项卡式用户界面？

我有标签，如果 MainActivity 并且我试图在片段内有标签

@JonnyWright 试试这个：maxalley.wordpress.com/2013/05/18/…

@CantThinkOfAnything 是的，您可以使用 SimpleGestureListener 以编程方式使它们可滑动。

【参考方案2】：

查看下面的代码，如果您仍在寻找答案，它肯定会对您有所帮助，并且它适用于旧版本的 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
            public View createTabContent(String tag) 
                // TODO Auto-generated method stub
                return (new AnalogClock(getActivity()));
            
        );
        mTabHost.addTab(spec);
        spec = mTabHost.newTabSpec("tag2");
        spec.setIndicator("Favourate");
        spec.setContent(new TabHost.TabContentFactory() 

            @Override
            public View createTabContent(String tag) 
                // TODO Auto-generated method stub
                return (new AnalogClock(getActivity()));
            
        );
        mTabHost.addTab(spec);
        return rootView;

this code how to give Page Link

【参考方案4】：

如果您使用：https://***.com/a/34224495/1386969

确保布局看起来像：

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

<TabHost
    android:id="@+id/tabhost"
    android:layout_
    android:layout_>

    <TabWidget
        android:id="@android:id/tabs"
        android:layout_
        android:layout_>
    </TabWidget>

    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_
        android:layout_>
    </FrameLayout>
</TabHost>
