使用xrecyclerview+OK+Fresco加载图片实现商品列表

首先导入依赖

compile 'com.jcodecraeer:xrecyclerview:1.3.2'
    compile 'com.google.code.gson:gson:2.7'
    compile 'com.squareup.okhttp3:okhttp:3.2.0'
    compile 'com.squareup.okio:okio:1.7.0'
    compile 'com.facebook.fresco:fresco:0.12.0'

然后是布局文件，切记将母布局上的灰色的一行粘贴到使用的布局中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:layout_height="wrap_content"
    android:orientation="vertical"
    tools:context="com.example.administrator.day2_demo.view.MainActivity">

    <com.jcodecraeer.xrecyclerview.XRecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:overScrollMode="never"
        android:id="@+id/recy"></com.jcodecraeer.xrecyclerview.XRecyclerView>

</LinearLayout>

item布局将样式方法前的Android改为fresco

xmlns:fresco="http://schemas.android.com/apk/res-auto"放入母布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:fresco="http://schemas.android.com/apk/res-auto"

    android:orientation="horizontal">

        fresco:roundingBorderWidth="2dp"

        android:id="@+id/img" />

    <LinearLayout
        android:layout_marginLeft="10dp"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="100dp">

        <TextView

            android:layout_marginTop="8dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/price01"
            android:textSize="22sp"
            android:text="11111"

        <TextView

以下是View视图层

IMainView

public interface IMainView {
    void ShowGoods(List<GoodsBean.DataBean> list);

    int pscid();
}

MyApp

public class MyApp extends Application {
    private static MyApp mInstance;
    @Override
    public void onCreate() {
        super.onCreate();
        mInstance=this;
        Fresco.initialize(this);


    }
    public static MyApp getInstance(){
        return mInstance;
    };
}

以下是model层

public interface IModel {
    void getDate(String url, Map<String,String> map, GoodsListener goodsListener);
}

IModelImpl

public class IModelImpl implements IModel {
    @Override
    public void getDate(String url, Map<String, String> map, final GoodsListener goodsListener) {
        OKHttpUtils okHttpUtils=new OKHttpUtils();
        okHttpUtils.okPost(url,map);
        okHttpUtils.setOnLoginListener(new OKHttpUtils.LoginListener() {
            @Override
            public void loginSuccess(String json) {
                goodsListener.GoodsSuccess(json);
            }

            @Override
            public void loginError(String error) {
                goodsListener.GoodsError(error);
            }
        });
    }
}

然后是Bean

public class GoodsBean {

P层

IPresenter

public interface IPresenter {
    void getGoods(IModel iModel, IMainView iMainView);
}

public class IPresenterImpl implements IPresenter {
    @Override
    public void getGoods(IModel iModel, final IMainView iMainView) {
        Map<String,String> map=new HashMap<>();
        map.put("pscid",iMainView.pscid()+"");
        iModel.getDate(Httpfig.goods_url, map, new GoodsListener() {
            @Override
            public void GoodsSuccess(String json) {
                Gson gson=new Gson();
                GoodsBean goodsBean = gson.fromJson(json, GoodsBean.class);
                List<GoodsBean.DataBean> data = goodsBean.getData();
                iMainView.ShowGoods(data);
            }

            @Override
            public void GoodsError(String error) {

            }
        });
    }
}

最后主MainActivity方法

public class MainActivity extends AppCompatActivity implements IMainView{
    private XRecyclerView xr;
    private static final String TAG = "MainActivity";
    private MyAdapter adapter;
    private int pscid = 1;
    private Handler mHandler = new Handler();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        xr = findViewById(R.id.recy);

        xr.setLayoutManager(new LinearLayoutManager(this));
        IPresenterImpl presenter = new IPresenterImpl();
        presenter.getGoods(new IModelImpl(),this);
        xr.setLoadingListener(new XRecyclerView.LoadingListener() {
            @Override
            public void onRefresh() {
                MainActivity.this.pscid++;
                IPresenterImpl presenter = new IPresenterImpl();
                presenter.getGoods(new IModelImpl(),MainActivity.this);
                xr.refreshComplete();
            }

            @Override
            public void onLoadMore() {

                MainActivity.this.pscid++;
                IPresenterImpl presenter = new IPresenterImpl();
                presenter.getGoods(new IModelImpl(),MainActivity.this);

            }
        });

    }

    @Override
    public void ShowGoods(List<GoodsBean.DataBean> list) {
        adapter = new MyAdapter(MainActivity.this,list);
        xr.setAdapter(adapter);
        Log.d(TAG, "ShowGoods: "+list.size());
    }

    @Override
    public int pscid() {
        return MainActivity.this.pscid;
    }
}
