Android—根据URL获取Bitmap图片

来源：互联网发布：安卓免费源码网编辑：程序博客网时间：2024/05/21 18:26

1、根据图片的URL路径来获取网络图片，核心代码如下：（1）public static Bitmap getBitmap(String path) throws IOException{URL url = new URL(path);HttpURLConnection conn = (HttpURLConnection)url.openConnection();conn.setConnectTimeout(5000);conn.setRequestMethod("GET");if(conn.getResponseCode() == 200){InputStream inputStream = conn.getInputStream();Bitmap bitmap = BitmapFactory.decodeStream(inputStream);return bitmap;}return null;}

public static Bitmap getBitMBitmap(String urlpath) { Bitmap map = null; try {  URL url = new URL(urlpath);  URLConnection conn = url.openConnection();  conn.connect();  InputStream in;  in = conn.getInputStream();  map = BitmapFactory.decodeStream(in); // TODO Auto-generated catch block  } catch (IOException e) {  e.printStackTrace(); } return map;}

（2）看评论

</pre>（3）<pre name="code" class="java">/*** 得到本地或者网络上的bitmap url - 网络或者本地图片的绝对路径,比如:* * A.网络路径: url="http://blog.foreverlove.us/girl2.png" ;* * B.本地路径:url="file://mnt/sdcard/photo/image.png";* * C.支持的图片格式 ,png, jpg,bmp,gif等等* * @param url* @return*/public static Bitmap GetLocalOrNetBitmap(String url){Bitmap bitmap = null;InputStream in = null;BufferedOutputStream out = null;try{in = new BufferedInputStream(new URL(url).openStream(), Constant.IO_BUFFER_SIZE);final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();out = new BufferedOutputStream(dataStream, Constant.IO_BUFFER_SIZE);copy(in, out);out.flush();byte[] data = dataStream.toByteArray();bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);data = null;return bitmap;}catch (IOException e){e.printStackTrace();return null;}}

//Constant.IO_BUFFER_SIZE 是一个常量而已，可以改成常数，比如2*1024，其实取决于你的图片大小，自己根据图片的大小自己设定吧。。。。
