1、下面是一个简单的Demo,仅供参考

package com.example.fragmentpageadapter;

import java.util.List;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.FragmentTabHost;

public class MainActivity extends FragmentActivity {
    private FragmentTabHost mTabHost = null;;
    private List<Fragment> list;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.fragments_tabs);

        mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
        mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

        mTabHost.addTab(mTabHost.newTabSpec("0").setIndicator("新闻"), NewsFragment.class, null);
        mTabHost.addTab(mTabHost.newTabSpec("1").setIndicator("音乐"), LifeFragment.class, null);
        mTabHost.addTab(mTabHost.newTabSpec("2").setIndicator("人生"), NewsFragment.class, null);

    }

    @Override
    protected void onDestroy() {
        // TODO Auto-generated method stub
        super.onDestroy();
        mTabHost = null;
    }
}

2、fragments_tabs.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    
    <android.support.v4.app.FragmentTabHost
        android:id="@android:id/tabhost"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        
        <TabWidget 
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"/>
    </android.support.v4.app.FragmentTabHost>
    
    <!-- 这个布局决定了标签在上面还是在下面显示 -->
    <FrameLayout 
        android:id="@+id/realtabcontent"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
    
</LinearLayout>

3、NewsFragment.java

package com.example.fragmentpageadapter;

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

public class NewsFragment extends Fragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        android.util.Log.d("mark", "onCreate()--------->news Fragment");
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        View view = inflater.inflate(R.layout.news, null);
        android.util.Log.d("mark", "onCreateView()--------->news Fragment");
        return view;
    }

    @Override
    public void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
        android.util.Log.d("mark", "onPause()--------->news Fragment");
    }
 
}
