侧拉+TabLayout切换fragment+Viewpager轮播图小圆点和图片上显示标题+多条目+上拉加载+下拉刷新

1.MainActivity主页面

package com.example.zonghelianxi01;

import android.annotation.SuppressLint;
import android.support.annotation.Nullable;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.MenuItem;

import com.example.Apaper.TabAdaper;
import com.example.Fragment.LiftFragment;

public class MainActivity extends AppCompatActivity {

    private DrawerLayout layout;
    private ActionBarDrawerToggle toggle;
    private ViewPager viewPager;
    private TabLayout tabLayout;

    @SuppressLint("ResourceType")
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //为 空是添加fragment
        if(savedInstanceState == null){
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.f_layout,new LiftFragment())
                    .commit();
        }
        //初始化view
        initView();
    }
    //初始化view
    private void initView() {
        //获取资源id
        layout = findViewById(R.id.d_layout);
        //允许标题栏显示左边图片
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        //ActionBar和DrawerLayout中间人
        toggle = new ActionBarDrawerToggle(this,layout,R.string.open_start,R.string.close_start);
        layout.addDrawerListener(toggle);
        toggle.syncState();
        //获取资源id
        viewPager = findViewById(R.id.v_page);
        //设置适配器
        viewPager.setAdapter(new TabAdaper(getSupportFragmentManager()));
        //获取资源id
        tabLayout = findViewById(R.id.t_layout);
        tabLayout.setupWithViewPager(viewPager);
    }

    //支持点击
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if(toggle.onOptionsItemSelected(item)){
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
    //点击跳转
    public void showPage(int i) {
        viewPager.setCurrentItem(i);
        layout.closeDrawer(Gravity.START);
    }
}

2.Fragment提取的基类BaseFragment

package com.example.Fragment;

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

public abstract class BaseFragment extends Fragment {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(getLayoutResId(),container,false);
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        //初始化view
        initView(view);
        //初始化数据
        initData();
    }
    //初始化数据
    protected abstract void initData();
    //初始化view
    protected abstract void initView(View view);

    protected abstract int getLayoutResId();
}

3.侧拉的适配页面

package com.example.Apaper;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.example.zonghelianxi01.R;

public class LiftAdaper extends BaseAdapter {
    private String[] pageName = new String[]{
            "资讯","社区","群组","我的"
    };
    private Context context;
    private final int ITEM_COUNT = 2;
    private final int IMAGE_TYPE = 0;
    private final int TEXT_TYPE = 1;
    public LiftAdaper(Context context) {
        this.context = context;
    }

    @Override
    public int getCount() {
        return pageName.length+1;
    }

    @Override
    public String getItem(int position) {
        //当position==0；
        if(position == 0){
            return null;
        }
        return pageName[position-1];
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public int getViewTypeCount() {
        return ITEM_COUNT;
    }

    @Override
    public int getItemViewType(int position) {
        return position==0?IMAGE_TYPE:TEXT_TYPE;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if(convertView == null){
            convertView = LayoutInflater.from(context).inflate(
                    getItemViewType(position)==IMAGE_TYPE? R.layout.image_item:R.layout.text_item
                    ,parent,false);
            holder = new ViewHolder(convertView);
        }else{
            holder = (ViewHolder) convertView.getTag();
        }
        if(getItemViewType(position)==TEXT_TYPE){
            holder.bind(getItem(position));
        }
        return convertView;
    }
    //创建寄存器
    class ViewHolder{
        TextView textView;
        ImageView imageView;
        //获取资源id
        public ViewHolder(View convertView) {
            textView = convertView.findViewById(R.id.lift_text);
            imageView = convertView.findViewById(R.id.lift_image);
            convertView.setTag(this);
        }
        //赋值
        public void bind(String item) {
            textView.setText(item);
            if(imageView!=null){
                imageView.setImageResource(R.mipmap.ic_launcher);
            }

        }
    }
}

4.侧拉的fragment

package com.example.Fragment;

import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;

import com.example.Apaper.LiftAdaper;
import com.example.zonghelianxi01.MainActivity;
import com.example.zonghelianxi01.R;

public class LiftFragment extends BaseFragment {

    private ListView listView;

    //初始化数据
    @Override
    protected void initData() {

    }
    //初始化view
    @Override
    protected void initView(View view) {
        //获取资源id
        listView = view.findViewById(R.id.menus);
        //设置适配器
        listView.setAdapter(new LiftAdaper(getActivity()));
        //点击跳转
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //图片不可点击
                if(position == 0){
                    return;
                }
                ((MainActivity)getActivity()).showPage(position-1);
            }
        });
    }
    //初始化加载布局
    @Override
    protected int getLayoutResId() {
        return R.layout.liftfragment;
    }
}

5.侧拉的布局多条目实现

5.1侧拉显示头像布局
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <ImageView
        android:id="@+id/lift_image"
        android:layout_width="100dp"
        android:layout_height="100dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        android:src="@mipmap/ic_launcher"
        />
</android.support.constraint.ConstraintLayout>
5.2侧拉显示文字布局
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <TextView
        android:id="@+id/lift_text"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        android:padding="15dp"
        android:text="TEXT"
        android:gravity="center"
        />
</android.support.constraint.ConstraintLayout>

6.tablayout切换页面

package com.example.Apaper;

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

import com.example.Fragment.FragmentFour;
import com.example.Fragment.FragmentOne;
import com.example.Fragment.FragmentThree;
import com.example.Fragment.FragmentTwo;

public class TabAdaper extends FragmentPagerAdapter {
    private String[] pageName = new String[]{
            "资讯","社区","群组","我的"
    };
    public TabAdaper(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int i) {
        switch (i){
            case 0:
                return new FragmentOne();
            case 1:
                return new FragmentTwo();
            case 2:
                return new FragmentThree();
            case 3:
                return new FragmentFour();
                default:
                    return new Fragment();
        }
    }

    @Nullable
    @Override
    public CharSequence getPageTitle(int position) {
        return pageName[position];
    }

    @Override
    public int getCount() {
        return pageName.length;
    }
}

7.主页面布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:id="@+id/d_layout"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <android.support.design.widget.TabLayout
            android:id="@+id/t_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            app:tabTextColor="@color/colorAccent"
            app:tabSelectedTextColor="@color/colorPrimary"
            app:tabIndicatorColor="@android:color/transparent"
            app:tabIndicatorHeight="1dp"
            />
        <android.support.v4.view.ViewPager
            android:id="@+id/v_page"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_above="@id/t_layout"
            />
    </RelativeLayout>
    <FrameLayout
        android:id="@+id/f_layout"
        android:layout_width="200dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#fff"
        />
</android.support.v4.widget.DrawerLayout>

8.轮播图的适配器

package com.example.Apaper;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v4.view.PagerAdapter;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;

import com.example.Bean.ImageBean;
import com.nostra13.universalimageloader.core.ImageLoader;

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

public class ImageAdaper extends PagerAdapter {
    private List<ImageBean.NewslistBean> mData;
    private Context context;

    public ImageAdaper(List<ImageBean.NewslistBean> mData, Context context) {
        this.mData = mData;
        this.context = context;
    }

    @Override
    public int getCount() {
        return mData.size()>0?5000:0;
    }

    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object o) {
        return view==o;
    }
    public ImageBean.NewslistBean getItem(int position){
        return mData.get(position%mData.size());
    }
    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        ImageView imageView = new ImageView(context);
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        container.addView(imageView);
        ImageLoader.getInstance().displayImage(getItem(position).getPicUrl(),imageView);
        return imageView;
    }

    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
        container.removeView((View) object);
    }
}

9.显示内容的适配器
