直接看代碼：MainActivity：

package com.example.textwsjdemo;import com.nostra13.universalimageloader.cache.disc.naming.Md5FileNameGenerator;import com.nostra13.universalimageloader.core.DisplayImageOptions;import com.nostra13.universalimageloader.core.ImageLoader;import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;import com.nostra13.universalimageloader.core.assist.QueueProcessingType;import com.nostra13.universalimageloader.core.display.RoundedBitmapDisplayer;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.ImageView;public class MainActivity extends Activity {    private String url;private Button bt_hehe;private ImageView iv_photo;private DisplayImageOptions defaultOptions;private ImageLoaderConfiguration config;@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                initView();                        defaultOptions = new DisplayImageOptions.Builder()        .showStubImage(R.drawable.ic_launcher)         //載入開始預設的圖片              .showImageForEmptyUri(R.drawable.ic_launcher)     //url爲空會顯示該圖片。自己放在drawable裡面的        .showImageOnFail(R.drawable.ic_launcher)    //載入圖片出現故障，會顯示該圖片        .cacheInMemory(true)     //緩衝用  fslae 不緩衝        .cacheOnDisc(true)      //緩衝用        .displayer(new RoundedBitmapDisplayer(5))  //圖片圓角顯示，值為整數        .build();                config = new ImageLoaderConfiguration.Builder(MainActivity.this)        .defaultDisplayImageOptions(defaultOptions)        .threadPriority(Thread.NORM_PRIORITY - 2)        .denyCacheImageMultipleSizesInMemory()        .discCacheFileNameGenerator(new Md5FileNameGenerator())        .tasksProcessingOrder(QueueProcessingType.LIFO)//        .enableLogging() // Not necessary in common        .build();        ImageLoader.getInstance().init(config);                    }private void initView() {//圖片URLurl = "http://file.koolearn.com/20131018/1382077932449.jpg";bt_hehe = (Button) findViewById(R.id.bt_hehe);iv_photo = (ImageView) findViewById(R.id.iv_photo);bt_hehe.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubImageLoader.getInstance().displayImage(url,iv_photo, defaultOptions); //url為圖片地址，iv_photo 為ImageView布局，}});}    }

就這點代碼就能夠實現載入網狀圖片。匯入Image-Loader 的jar包就可以
