效果图：

代码功能：

（1）用ViewPager+Fragment实现TabHost，ViewPager的每一个Page均是Fragment。ViewPager中的Fragment可以动态添加、删除。底部的Tab选项卡点击后选择ViewPager中相应的Fragment。

（2）ViewPager左右侧滑时候，底部的Tab选项卡也跟随相应做出对应的滑动。

MainActivity.java

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Fragment newFragment =new  ViewPagerAndFragmentTabHost();
        FragmentTransaction transaction =getSupportFragmentManager().beginTransaction();
        transaction.replace(R.id.fragment,newFragment);
        transaction.commit();

    }
}

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >
   
    <FrameLayout 
   		android:id="@+id/fragment"  
        android:layout_width="match_parent"
    	android:layout_height="match_parent">	
    </FrameLayout>
    
    
 </LinearLayout>

重点是此类：ViewPagerAndFragmentTabHost.java 实现全部功能。
