android 获取网络图片显示在Gallery中

其实很简单，Gallery 里设置 setAdapter() 里面添加图片的资源，这需要继承BaseAdapter 重写里面的函数，值得一提的是需要写一个xml

< ?xml version="1.0" encoding="utf-8"?>

< resources>

< declare-styleable name="Gallery">

< attr name="android:galleryItemBackground" />

< /declare-styleable>

< /resources>

主要代码：

private Gallery myGallery01;

/* 图片资源 */

private String[] myImageURL = new String[]

{

"http://www.chinajilin.com.cn/att/site1/20071116/"

+ "img-1196620280651.jpg",

@Override

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

myGallery01 = (Gallery) findViewById(R.id.myGallery01);

myGallery01.setAdapter(new myInternetGalleryAdapter(this));

}

/* BaseAdapter */

public class myInternetGalleryAdapter extends BaseAdapter

{

private Context myContext;

private int mGalleryItemBackground;

/* 构造函数 Context */

public myInternetGalleryAdapter(Context c)

{

this.myContext = c;

// 检索 这方面的主题风格的属性

TypedArray a = myContext

.obtainStyledAttributes(R.styleable.Gallery);

//得到资源标识

mGalleryItemBackground = a.getResourceId(
