需要生成本地的API:请参考博客：  
[Python3实现 将MySQL数据库中的记录生成JSON数据][Python3_ _MySQL_JSON]  
[Python生成本地API][Python_API]

代码实现：  
首先实现清单文件:  
**AndroidManifest.xml**

<?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.iyuba.mytablayout">
    
        <uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    
        <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/AppTheme">
            <activity android:name=".ContentActivity"></activity>
            <activity android:name=".MainActivity">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
    
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
    
    </manifest>

**acitivity\_main.xml**  
启动页面布局  
使用TabLayout,其设置Tab的模式是"可滑动的" ，app:tabMode=“scrollable”  
app:tabMode="fixed"是不可滑动的

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity"
        android:orientation="vertical">
        <android.support.design.widget.AppBarLayout
            android:id="@+id/appbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_scrollFlags="scroll|enterAlways"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>
            <android.support.design.widget.TabLayout
                android:id="@+id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:tabIndicatorColor="#ADBE107E"
                app:tabMode="scrollable"/>
    
        </android.support.design.widget.AppBarLayout>
    
        <android.support.v4.view.ViewPager
            android:id="@+id/viewpager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
    
    </LinearLayout>

**MainActivity.java**  
说明：AppBarLayout是Android Design Support Library新加的控件，继承自LinearLayout,它用来将Toolbar和TabLayout组合起来作为一个整体。Toolbar是应用内容的标准工具栏,可以说是Actionbar的升级版

**FragmentAdapter.java**  
这是分类标题的Adapter,他主要处理了两件事:  
第一件就是根据不同的position返回不同的Fragment,  
另一件事是根据不同的position返回不同的title

package com.iyuba.mytablayout;
    
    import android.content.Context;
    import android.support.annotation.Nullable;
    import android.support.v4.app.Fragment;
    import android.support.v4.app.FragmentManager;
    import android.support.v4.app.FragmentStatePagerAdapter;
    
    import java.util.List;
    
    public class FragmentAdapter extends FragmentStatePagerAdapter {
        private List<Fragment> mFragments;
        private List<String> mTitles;
        private Context mContext;
    
        public FragmentAdapter(FragmentManager fm,List<Fragment> fragments,List<String> titles){
            super(fm);
            mFragments = fragments;
            mTitles = titles;
        }
    
        @Override
        public Fragment getItem(int i) {
            return mFragments.get(i);
        }
    
        @Override
        public int getCount() {
            return mFragments.size();
        }
    
        @Nullable
        @Override
        public CharSequence getPageTitle(int position) {
            return mTitles.get(position);
        }
    }
