本文详细介绍了一种使用TabLayout和ViewPager实现动态切换不同页面的布局方式，通过自定义适配器MyAdapterFragment来管理多个Fragment，实现了标签页与内容页的联动效果。

布局文件

<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.TabLayout
android:layout_width=“match_parent”
android:layout_height=“wrap_content”
android:id="@+id/Tab_Layout"
></android.support.design.widget.TabLayout>

<android.support.v4.view.ViewPager
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/Vp"
    ></android.support.v4.view.ViewPager>

代码部分
package com.example.monitwo.fragment;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.example.monitwo.R;
import com.example.monitwo.fragmentadapter.MyAdapterFragment;

import java.util.ArrayList;
import java.util.List;

/**

A simple {@link Fragment} subclass.
*/
public class AAFragment extends Fragment {

private TabLayout Tab_Layout;
private ViewPager Vp;
private List fList;
private List sList;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_aa, null);
```
 initView(v);
 initData();
 MyAdapterFragment myAdapterFragment=new MyAdapterFragment(getChildFragmentManager(),fList,sList);
 Vp.setAdapter(myAdapterFragment);
 Tab_Layout.setupWithViewPager(Vp);
 return v;
```
}

private void initView(View v) {
Tab_Layout = (TabLayout) v.findViewById(R.id.Tab_Layout);
Vp = (ViewPager) v.findViewById(R.id.Vp);
}

private void initData(){
```
 fList= new ArrayList<>();
 fList.add(new AAAFragment());
 fList.add(new BBBFragment());
 fList.add(new CCCFragment());
 sList = new ArrayList<>();
 sList.add("热门影片");
 sList.add("正在上映");
 sList.add("即将上映");
```
}

}
适配器
package com.example.monitwo.fragmentadapter;

import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

import java.util.List;

public class MyAdapterFragment extends FragmentPagerAdapter {

private List<Fragment> fList;
private List<String> sList;

public MyAdapterFragment(FragmentManager fm, List<Fragment> fList, List<String> sList) {
    super(fm);
    this.fList = fList;
    this.sList = sList;
}



@Override
public Fragment getItem(int i) {
    return fList.get(i);
}

@Override
public int getCount() {
    return fList.size();
}

@Nullable
@Override
public CharSequence getPageTitle(int position) {
    return sList.get(position);
}

}
