android方便的显示网络图片

import java.io.InputStream;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.AsyncTask;
import android.widget.ImageView;

public class DownLoadImage extends AsyncTask<String, Void, Bitmap> {
    ImageView imageView;  

    public DownLoadImage(ImageView imageView) {
        // TODO Auto-generated constructor stub
        this.imageView = imageView;
    }  

    @Override
    protected Bitmap doInBackground(String... urls) {
        // TODO Auto-generated method stub
        String url = urls[0];
        Bitmap tmpBitmap = null;
        try {
            InputStream is = new java.net.URL(url).openStream();
            tmpBitmap = BitmapFactory.decodeStream(is);
        } catch (Exception e) {
            e.printStackTrace();  

        }
        return tmpBitmap;
    }  

    @Override
    protected void onPostExecute(Bitmap result) {
        // TODO Auto-generated method stub
        imageView.setImageBitmap(result);
    }
}  

写一个这样的工具类，然后用的时候很简单

DownLoadImage t=new DownLoadImage(imgview);
t.execute(imgurl);

如果大家谁有更好的办法 欢迎讨论交流。
