Android获取网络上图片的

调用代码显示代码的拍图片ImageService中的静态方法。

public void showimage(View v){        String path = pathText.getText().toString();        try {            Bitmap bitmap = ImageService.getImage(path);            imageView.setImageBitmap(bitmap);        } catch (Exception e) {            e.printStackTrace();            Toast.makeText(getApplicationContext(), R.string.error, 1).show();        }    }

path 是获取TextView中的路径文件
ImageService.java 文件

import java.io.InputStream;import java.net.HttpURLConnection;import java.net.URL;import android.graphics.Bitmap;import android.graphics.BitmapFactory;public class ImageService {    /**     * 获取图片     * @param path 图片路径     * @return     */    public static Bitmap getImage(String path) throws Exception{        URL url = new URL(path);        HttpURLConnection conn = (HttpURLConnection) url.openConnection();        conn.setConnectTimeout(5000);        conn.setRequestMethod("GET");        if(conn.getResponseCode() == 200){            InputStream inStream = conn.getInputStream();            Bitmap bitmap = BitmapFactory.decodeStream(inStream);            return bitmap;            /*byte[] data = StreamTool.read(inStream);            Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);            return bitmap;*/        }        return null;    }}

以上就是最简单从获取服务器中的图片的方法。
