本文介绍了一个简单的Android应用示例，展示了如何利用Facebook的Fresco库进行图片加载及圆形展示。通过创建自定义的App类继承Application，并在onCreate()方法中初始化Fresco，然后在MainActivity中设置SimpleDraweeView组件加载网络图片。

MyApp

package com.jj.yuekao.demo05;

import android.app.Application;

import com.facebook.drawee.backends.pipeline.Fresco;

/**
 * Created by jj on 2018/3/6.
 */

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Fresco.initialize(this);
    }
}

MainActivity

package com.jj.yuekao.demo05;

import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.facebook.drawee.view.SimpleDraweeView;
import com.jj.yuekao.R;

public class Main5Activity extends AppCompatActivity {
   private SimpleDraweeView iv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main5);
        iv=(SimpleDraweeView)findViewById(R.id.iv_id3);

        iv.setImageURI(Uri.parse("http://pic.sogou.com/pics/recompic/detail.jsp?category=%E7%BE%8E%E5%A5%B3&tag=%E6%91%84%E5%BD%B1#0%2617420446"));
    }
}
