TabLayout+PullToRefreshListView连用

首先将TabLayout依赖包导入工程中

compile 'com.android.support:design:24.2.0'

主布局中

      <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabIndicatorColor="@color/red"
            app:tabMode="scrollable"
            app:tabSelectedTextColor="@color/red"
            app:tabTextColor="@color/black"/>
        <android.support.v4.view.ViewPager
            android:id="@+id/vp_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

Activity中

private TabLayout mTabLayout;
    private ViewPager mViewPager;
    private String[] channels = {"推荐","热点","体育","娱乐","社会","汽车","教育","财经","科技","游戏"};
    private String[] Urls={"http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
            "http://gank.io/api/data/Android/10/1",
    };
    private LayoutInflater mInflater;
    private List<ChannelFragment> mViewList=new ArrayList<>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mTabLayout = (TabLayout) findViewById(R.id.tabs);
        mViewPager = (ViewPager) findViewById(R.id.vp_view);
        mInflater = LayoutInflater.from(this);

        for (int i = 0; i < channels.length; i++) {
            //创建栏目的fragment
            ChannelFragment fragment = new ChannelFragment();
            Bundle b = new Bundle();
            b.putString("name", channels[i]);//传递名字
            b.putString("url", Urls[i]);
            fragment.setArguments(b);
            //收集fragment
            mViewList.add(fragment);
            //给tablayout添加tab选项卡
            mTabLayout.addTab(mTabLayout.newTab().setText(channels[i]));//添加tab选项卡

        }
        FragmentManager fm = getSupportFragmentManager();
        MyFragmentPagerAdapter adapter=new MyFragmentPagerAdapter(fm,mViewList);
        mViewPager.setAdapter(adapter);//关联适配器
        mTabLayout.setupWithViewPager(mViewPager);//将Tablayout与Viewpager建立连接

    }
    class MyFragmentPagerAdapter extends FragmentPagerAdapter {
        private List<ChannelFragment> mViewList;

        public MyFragmentPagerAdapter(FragmentManager fm, List<ChannelFragment> mViewList) {
            super(fm);
            this.mViewList = mViewList;
        }

        @Override
        public Fragment getItem(int position) {
            return mViewList.get(position);
        }

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

        @Override
        public CharSequence getPageTitle(int position) {

            return channels[position];//页卡标题
        }
    }

创建一个Fragment类继承Fragment,注意创建的Fragment当然不能叫Fragment

public class ChannelFragment extends Fragment{
    private String name;
    private String news_url;
    private PullToRefreshListView pullToRefreshListView;
    private  List<User.ResultsBean> results;
    private  PullOnRefreshAdapter adapter;
    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //接受传过来的值
        Bundle bundle = getArguments();
        name = (String) bundle.get("name");
        news_url = (String) bundle.get("url");
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view=inflater.inflate(R.layout.fragment,null);
        //获取资源ID
        pullToRefreshListView=(PullToRefreshListView) view.findViewById(R.id.pull_refresh_list);
        pullToRefreshData();
        //刷新
        pullToRefreshListView.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener<ListView>() {
            @Override
            public void onRefresh(PullToRefreshBase<ListView> refreshView) {
                pullToRefreshData();
            }
        });
        //加载
        pullToRefreshListView.setOnLastItemVisibleListener(new PullToRefreshBase.OnLastItemVisibleListener() {
            @Override
            public void onLastItemVisible() {
                LoadMoreData();
            }
        });
        return view;
    }
    //刷新
    public void pullToRefreshData(){
        new AsyncTask<String,Integer,String>(){

            @Override
            protected String doInBackground(String... strings) {
                //解析
                String str=new NetWorksUtils().getJsonUrlJiexi(news_url+"1");
                return str;
            }

            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                Gson gson = new Gson();
                User user = gson.fromJson(s, User.class);
                results = user.getResults();
                //关联适配器
                adapter=new PullOnRefreshAdapter(results,getActivity());
                pullToRefreshListView.setAdapter(adapter);
                //停止刷新
                pullToRefreshListView.onRefreshComplete();
            }
        }.execute(news_url);
    }
//加载
    public void LoadMoreData(){

        new AsyncTask<String,Integer,String>(){

            @Override
            protected String doInBackground(String... strings) {
               //解析
                String str=new NetWorksUtils().getJsonUrlJiexi(news_url+"1");
                return str;
            }

            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                Gson gson = new Gson();
                User user = gson.fromJson(s, User.class);
                //新集合
                List<User.ResultsBean> results2 = user.getResults();
                //上拉添加一遍
                results.addAll(results2);
                //刷新适配器
                adapter.notifyDataSetChanged();
           }
        }.execute(news_url);
    }
}

fragment布局中写PullToRefreshListView

<com.handmark.pulltorefresh.library.PullToRefreshListView
        xmlns:ptr="http://schemas.android.com/apk/res-auto"
        android:id="@+id/pull_refresh_list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:cacheColorHint="#000000"
        android:divider="#19000000"
        android:dividerHeight="4dp"
        android:fadingEdge="none"
        android:fastScrollEnabled="false"
        android:footerDividersEnabled="false"
        android:headerDividersEnabled="false"
        android:smoothScrollbar="true"
        ptr:ptrAnimationStyle="rotate"
        ptr:ptrHeaderTextColor="#ffffff"
        ptr:ptrHeaderSubTextColor="#00ffff"
        ptr:ptrHeaderBackground="@null"
        ptr:ptrDrawable="@mipmap/ic_launcher"/>

创建要解析的Json串的类进行封装，接着创建一个工具类

public class NetWorksUtils {
    //解析的方法
    public String getJsonUrlJiexi(String jsonStr){
        URL url=null;
        HttpURLConnection httpURLConnection=null;
        String JsonUrl="";
        try {
            //进行网络解析
            url=new URL(jsonStr);
            httpURLConnection= (HttpURLConnection) url.openConnection();
            httpURLConnection.setConnectTimeout(5000);
            httpURLConnection.setReadTimeout(5000);
            //获取响应码
            int responseCode = httpURLConnection.getResponseCode();
            if (responseCode==200){
                InputStream inputStream = httpURLConnection.getInputStream();
                byte[] bytes = new byte[1024];
                int i=0;
                while ((i=inputStream.read(bytes))!=-1){
                    JsonUrl +=new String(bytes,0,i);
                }
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return JsonUrl;
    }
}

创建适配器MyAdapter:

private List<DataBean.DataBea> list;
    private Context context;
    private LayoutInflater inflater;

    public MyAdapter(List<DataBean.DataBea> list, Context context) {
        this.list = list;
        this.context = context;
        inflater = LayoutInflater.from(context);
    }

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

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

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

    @Override
    public int getViewTypeCount() {
        return 2;
    }

    @Override
    public int getItemViewType(int position) {
        int rs = 0;
        if(position%2==0){
            rs = 0;
        }else if(position%2==1){
            rs = 1;
        }
        return rs;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        int rs = getItemViewType(position);
        ViewHoder1 hoder1;
        ViewHoder2 hoder2;
        if(rs==0){
            if(convertView==null){
                hoder1 = new ViewHoder1();
                convertView = inflater.inflate(R.layout.item1, null);
                hoder1.image = (ImageView) convertView.findViewById(R.id.image);
                hoder1.tv1 = (TextView) convertView.findViewById(R.id.tv1);
                convertView.setTag(hoder1);
            }else{
                hoder1 = (ViewHoder1) convertView.getTag();
            }
            ImageLoader.getInstance().displayImage(list.get(position).getImg(),hoder1.image);
            hoder1.tv1.setText(list.get(position).getUserAge()+"\n"+list.get(position).getTopTime()+"\n"+
                    list.get(position).getRecommend()+"\n"+list.get(position).getUrl()+"\n"+
                    list.get(position).getCreateTime()+"\n"+list.get(position).getHxKey()+"\n"+
                    list.get(position).getYulin()+"\n"+list.get(position).getStar()+"\n"+
                    list.get(position).getTitle()+"\n"+list.get(position).getOccupation()+"\n"+
                    list.get(position).getImpressEditId()+"\n"+list.get(position).getImpressType()+"\n"+
                    list.get(position).getReplyTimes()+"\n"+list.get(position).getRemark()+"\n"+
                    list.get(position).getClick()+"\n"+list.get(position).getIntroduction()+"\n"+
                    list.get(position).getSource()+"\n"+list.get(position).getUserName()+"\n"+
                    list.get(position).getReporter()+"\n"+list.get(position).getStatus()+"\n"+
                    list.get(position).getContent());

        }else if(rs==1){
            if(convertView==null){
                hoder2 = new ViewHoder2();
                convertView = inflater.inflate(R.layout.item2, null);
                hoder2.tv2 = (TextView) convertView.findViewById(R.id.tv2);
                convertView.setTag(hoder2);
            }else{
                hoder2 = (ViewHoder2) convertView.getTag();
            }
            hoder2.tv2.setText(list.get(position).getUserAge()+"\n"+list.get(position).getTopTime()+"\n"+
                    list.get(position).getRecommend()+"\n"+list.get(position).getUrl()+"\n"+
                    list.get(position).getCreateTime()+"\n"+list.get(position).getHxKey()+"\n"+
                    list.get(position).getYulin()+"\n"+list.get(position).getStar()+"\n"+
                    list.get(position).getTitle()+"\n"+list.get(position).getOccupation()+"\n"+
                    list.get(position).getImpressEditId()+"\n"+list.get(position).getImpressType()+"\n"+
                    list.get(position).getReplyTimes()+"\n"+list.get(position).getRemark()+"\n"+
                    list.get(position).getClick()+"\n"+list.get(position).getIntroduction()+"\n"+
                    list.get(position).getSource()+"\n"+list.get(position).getUserName()+"\n"+
                    list.get(position).getReporter()+"\n"+list.get(position).getStatus()+"\n"+
                    list.get(position).getContent());

        }
        return convertView;
    }

    class ViewHoder1{
        ImageView image;
        TextView tv1;
    }
    class ViewHoder2{
        TextView tv2;
    }

给PIllToRefreshListView加优化需要在写俩个子布局

第一个

<ImageView
    android:id="@+id/image"
    android:layout_width="60dp"
    android:layout_height="60dp" />
    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

第二个

<TextView
    android:id="@+id/text2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

在创建一个类用来网络加载图片

public class MyApp extends Application{
    @Override
    public void onCreate() {
        super.onCreate();
        //默认加载图片
        ImageLoaderConfiguration configuration=ImageLoaderConfiguration.createDefault(this);
        ImageLoader.getInstance().init(configuration);
    }
}
