<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"    />

需要添加权限

<uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

需要添加依赖

compile 'com.youth.banner:banner:1.4.9'compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

public class MainActivity extends AppCompatActivity {    String[] urls = {"http://img.my.csdn.net/uploads/201407/26/1406383265_8550.jpg",            "https://lh4.googleusercontent.com/--dq8niRp7W4/URquVgmXvgI/AAAAAAAAAbs/-gnuLQfNnBA/s160-c/A%252520Song%252520of%252520Ice%252520and%252520Fire.jpg",            "https://lh5.googleusercontent.com/-7qZeDtRKFKc/URquWZT1gOI/AAAAAAAAAbs/hqWgteyNXsg/s160-c/Another%252520Rockaway%252520Sunset.jpg",            "https://lh3.googleusercontent.com/--L0Km39l5J8/URquXHGcdNI/AAAAAAAAAbs/3ZrSJNrSomQ/s160-c/Antelope%252520Butte.jpg",            "https://lh6.googleusercontent.com/-8HO-4vIFnlw/URquZnsFgtI/AAAAAAAAAbs/WT8jViTF7vw/s160-c/Antelope%252520Hallway.jpg",            "https://lh4.googleusercontent.com/-WIuWgVcU3Qw/URqubRVcj4I/AAAAAAAAAbs/YvbwgGjwdIQ/s160-c/Antelope%252520Walls.jpg"};    private Banner banner;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        banner = (Banner) findViewById(R.id.banner);        //配置重写好的加载图片的类        banner.setImageLoader(new MLoader());        //需要传入一个图片地址的集合        banner.setImages(Arrays.asList(urls));        //开启轮播        banner.start();    }    private class MLoader extends ImageLoader{        //这个就是专门让我们重写,加载图片的具体逻辑        @Override        public void displayImage(Context context, Object path, ImageView imageView) {            com.nostra13.universalimageloader.core.ImageLoader instance = com.nostra13.universalimageloader.core.ImageLoader.getInstance();            instance.displayImage((String)path,imageView);        }    }}
