ImageView是Android程序中经常用到的组件，它将一个图片显示到屏幕上。

在UI xml定义一个ImageView如下：

public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.myimage);     ImageView image1 = (ImageView) findViewById(R.myImage.image);     //Bitmap bitmap = getLoacalBitmap("/aa/aa.jpg"); //从本地取图片     Bitmap bitmap =getHttpBitmap("http://blog.3gstdy.com/wp-content/themes/twentyten/images/headers/path.jpg");//从网上取图片     image1 .setImageBitmap(bitmap);    //设置Bitmap}/*** 加载本地图片* http://bbs.3gstdy.com* @param url* @return*/public static Bitmap getLoacalBitmap(String url) {     try {          FileInputStream fis = new FileInputStream(url);          return BitmapFactory.decodeStream(fis);     } catch (FileNotFoundException e) {          e.printStackTrace();          return null;     }}/*** 从服务器取图片*http://bbs.3gstdy.com* @param url* @return*/public static Bitmap getHttpBitmap(String url) {     URL myFileUrl = null;     Bitmap bitmap = null;     try {          Log.d(TAG, url);          myFileUrl = new URL(url);     } catch (MalformedURLException e) {          e.printStackTrace();     }     try {          HttpURLConnection conn = (HttpURLConnection) myFileUrl.openConnection();          conn.setConnectTimeout(0);          conn.setDoInput(true);          conn.connect();          InputStream is = conn.getInputStream();          bitmap = BitmapFactory.decodeStream(is);          is.close();     } catch (IOException e) {          e.printStackTrace();     }     return bitmap;}
