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。
