简单的Fresco加载图片

package com.example.frescolistview;import android.os.AsyncTask;import android.os.Bundle;import android.os.Handler;import android.support.v7.app.AppCompatActivity;import android.widget.ListView;import com.google.gson.Gson;import java.io.InputStream;import java.net.HttpURLConnection;import java.net.URL;import java.util.List;public class MainActivity extends AppCompatActivity {    private List<Bean.DataBean> list;    private ListView lv;    private MyBaseadapter adapter;    private Handler handler=new Handler(){        Runnable runnable=new Runnable() {            @Override            public void run() {                try {                    MainActivity.this.wait(1000);                } catch (Exception e) {                    e.printStackTrace();                }            }        };    };    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        lv= (ListView) findViewById(R.id.lv);        data();    }    public void data(){        jiexi("http://result.eolinker.com/iYXEPGn4e9c6dafce6e5cdd23287d2bb136ee7e9194d3e9?uri=vedio");    }    public void jiexi(String path){        new AsyncTask<String,Void,String>(){            @Override            protected void onPostExecute(String s) {                if (s!=null){                    Gson gson=new Gson();                    Bean bean = gson.fromJson(s, Bean.class);                    list = bean.getData();                    adapter=new MyBaseadapter(MainActivity.this,list);                    lv.setAdapter(adapter);                }            }            @Override            protected String doInBackground(String... params) {                try {                    URL url=new URL(params[0]);                    HttpURLConnection connection = (HttpURLConnection) url.openConnection();                    connection.setRequestMethod("GET");                    connection.setReadTimeout(3000);                    connection.setConnectTimeout(3000);                    int code = connection.getResponseCode();                    if (code==200){                        InputStream is = connection.getInputStream();                        return info.readFromNetWork(is);                    }                } catch (Exception e) {                    e.printStackTrace();                }                return null;            }        }.execute(path);    }}

以上便是MainActivity文件主要就是负责实现图片的listview布局展示

package com.example.frescolistview;import android.app.Application;import com.facebook.drawee.backends.pipeline.Fresco;/** * Created by HP on 2017/11/28. */public class MyApp extends Application {    @Override    public void onCreate() {        super.onCreate();        Fresco.initialize(this);    }}
以上便是首先通过初始化Fresco文件进行加载最后一定记得在maniface文件下注册

package com.example.frescolistview;import android.content.Context;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;import com.facebook.drawee.backends.pipeline.Fresco;import com.facebook.drawee.interfaces.DraweeController;import com.facebook.drawee.view.SimpleDraweeView;import java.util.List;/** * Created by HP on 2017/11/28. */public class MyBaseadapter extends BaseAdapter {    private List<Bean.DataBean> list;    private Context context;    public MyBaseadapter(Context context, List<Bean.DataBean> list) {        this.context=context;        this.list=list;    }    @Override    public int getCount() {        return list!=null?list.size():0;    }    @Override    public Object getItem(int position) {        return null;    }    @Override    public long getItemId(int position) {        return 0;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        convertView=View.inflate(context,R.layout.item,null);        SimpleDraweeView simpleDraweeView=(SimpleDraweeView) convertView.findViewById(R.id.main_simple_drawee_view);        TextView tv=(TextView) convertView.findViewById(R.id.tv);        tv.setText(list.get(position).getTitle());        DraweeController controller = Fresco.newDraweeControllerBuilder()                .setUri(list.get(position).getImage_url())                .setAutoPlayAnimations(true)                .build();        simpleDraweeView.setController(controller);        return convertView;    }}

以上便是适配器文件的配置

<?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="match_parent" tools:context="com.example.frescolistview.MainActivity"><ListView    android:id="@+id/lv"    android:layout_width="match_parent"    android:layout_height="match_parent"></ListView></LinearLayout>
以上是xmlmain-activity

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    xmlns:fresco="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent">    <com.facebook.drawee.view.SimpleDraweeView        android:layout_width="100dp"        android:layout_height="100dp"        fresco:roundAsCircle="true"        android:id="@+id/main_simple_drawee_view"        fresco:placeholderImage="@mipmap/ic_launcher"/>    <LinearLayout        android:orientation="vertical"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_alignParentTop="true"        android:layout_toRightOf="@+id/main_simple_drawee_view"        android:layout_toEndOf="@+id/main_simple_drawee_view">        <TextView            android:layout_marginTop="20dp"            android:id="@+id/tv"            android:layout_width="match_parent"            android:layout_height="wrap_content" />        <TextView            android:layout_marginTop="20dp"            android:id="@+id/tv1"            android:layout_width="match_parent"            android:layout_height="wrap_content" />    </LinearLayout></RelativeLayout>
以上就是item文件

dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    compile 'com.android.support:appcompat-v7:26.+'    compile 'com.android.support.constraint:constraint-layout:1.0.2'    testCompile 'junit:junit:4.12'    compile 'com.facebook.fresco:animated-gif:0.12.0'    compile 'com.facebook.fresco:fresco:0.11.0'    compile 'com.google.code.gson:gson:2.2.4'

最后在附送上依赖这边是简单的Fresco的使用
