iApp-v3 调用java加载网络图片

新建webpic.mjava
代码:

import android.graphics.drawable.BitmapDrawable;
import java.net.HttpURLConnection;
import java.net.URL;
import java.io.InputStream;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;

    public static BitmapDrawable get(String url){
        BitmapDrawable pic = null;
        try{
            URL u = new URL(url);
            HttpURLConnection conn = (HttpURLConnection) u.openConnection();
            conn.setRequestMethod("GET");
            conn.setConnectTimeout(5000);
            conn.setReadTimeout(5000);
            InputStream is = conn.getInputStream();
            Bitmap bmp = BitmapFactory.decodeStream(is);
            pic = new BitmapDrawable(bmp);
            is.close();
            conn.disconnect();
        }catch(Exception e){}
        return pic;
    }

iyu调用
代码:

t(){
  s id=图像id
  s img_url=xxx
  call(img,"mjava","webpic.get",img_url)
  ufnsui(){
    us(id, "src", img)
  }
}
