Android4.0加载网络图片问题

<P>4.0系统加载网络图片不能发在主线程中运行,否则会报异常,用新开线程方法可以解决:</P>

package com.smalt.thread;  
  
import java.io.InputStream;  
  
import android.graphics.Bitmap;  
import android.graphics.BitmapFactory;  
import android.os.AsyncTask;  
import android.util.Log;  
import android.widget.ImageView;  
  
/** 
 * 在4.0系统中显示网络图片 
 *  
 * @author Administrator 
 *  
 */  
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();  
            Log.i("test", e.getMessage());  
        }  
        return tmpBitmap;  
    }  
  
    @Override  
    protected void onPostExecute(Bitmap result) {  
        // TODO Auto-generated method stub   
        imageView.setImageBitmap(result);  
    }  
}  

 

加载图片方法:

String uriBaidu = "https://www.baidu.com/img/baidu_logo.gif";

 

new DownLoadImage((ImageView) findViewById(R.id.iv3)).execute(uriBaidu);
