首先是四个布局页面

第一个是主体布局

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/activity_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:context="com.example.dell.zklx03.MainActivity">
    
        <android.support.design.widget.TabLayout
            android:layout_width="match_parent"
            android:layout_height="60dp"
            android:id="@+id/tab"/>
    
    
        <android.support.v4.view.ViewPager
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/vp"/>
    </LinearLayout>

然后是item的布局

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="match_parent"
        android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:id="@+id/image"/>
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/tv"/>
    </LinearLayout>

然后是两个Fragment的布局

fragment\_blank

fragment\_alank

接下来就是代码部分了

主体代码

import android.support.design.widget.TabLayout;
    import android.support.v4.app.Fragment;
    import android.support.v4.app.FragmentManager;
    import android.support.v4.app.FragmentPagerAdapter;
    import android.support.v4.view.ViewPager;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    
    import java.util.ArrayList;
    import java.util.List;
    
    public class MainActivity extends AppCompatActivity {
    
        private TabLayout tab;
        private List<Fragment>data;
        private ViewPager vp;
        private List<String>titles;
        private MyAdatper myAdatper;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            initView();
    
            titles=new ArrayList<>();
            titles.add("第一页");
            titles.add("第二页");
            data=new ArrayList<>();
            data.add(new AlankFragment());
            data.add(new BlankFragment());
    
            myAdatper=new MyAdatper(getSupportFragmentManager());
            vp.setAdapter(myAdatper);
            tab.setupWithViewPager(vp);
        }
    
        private void initView() {
            tab = (TabLayout) findViewById(R.id.tab);
            vp = (ViewPager) findViewById(R.id.vp);
        }
        class MyAdatper extends FragmentPagerAdapter{
            public MyAdatper(FragmentManager fm) {
                super(fm);
            }
    
            @Override
            public Fragment getItem(int position) {
                return data.get(position);
            }
    
            @Override
            public int getCount() {
                return data.size();
            }
    
            @Override
            public CharSequence getPageTitle(int position) {
                return super.getPageTitle(position);
            }
        }
    }

MyApp的代码

import android.app.Application;
    
    import org.xutils.x;
    
    /**
     * Created by DELL on 2017/12/15.
     */
    
    public class MyApp extends Application {
        @Override
        public void onCreate() {
    
            x.Ext.init(this);
    
            x.Ext.setDebug(true);
        }
    }

MyGson的代码

import java.util.List;
    
    /**
     * Created by DELL on 2017/12/15.
     */
    
    public class MyGson {
    
        /**
