android从URL显示图像时出现错误

概述当我使用以下代码从url显示图像时,应用程序花费太多时间从服务器加载图像.如果要加载8-10张图像,则应用程序挂起.Bitmapmbmp=BitmapFactory.decodeStream(newjava.net.URL("urlname").openStream());Imageview_ref.setImageBitmap(mbmp);并在Logcat中获取09-1511:34:14

当我使用以下代码从url显示图像时,应用程序花费太多时间从服务器加载图像.如果要加载8-10张图像,则应用程序挂起.

Bitmap mbmp = BitmapFactory.decodeStream(new java.net.URL("urlname").openStream());ImagevIEw_ref.setimageBitmap(mbmp);

并在Logcat中获取

与此logcat错误消息,我仍然得到输出.

这是我更新的代码视图.

public VIEw getVIEw(int position, VIEw convertVIEw, VIEwGroup parent) {            // Todo auto-generated method stub            VIEw v = convertVIEw;            if(v == null){                LayoutInflater vl = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);                v = vl.inflate(R.layout.placesList, null);            }            FIElds o = results.get(position);            if (o != null) {                TextVIEw iv = (TextVIEw)v.findVIEwByID(R.ID.toptext);                ImageVIEw tv_Image = (ImageVIEw)v.findVIEwByID(R.ID.Locimage);                iv.setText(o.getLocationname());                                            try {                    Bitmap bitmap = BitmapFactory.decodeStream((inputStream) new URL(o.getLocationImage()).getContent());                    tv_Image.setimageBitmap(bitmap);                } catch (Exception e) {                    e.printstacktrace();                }            }            return v;        }           }

解决方法:

请尝试这个::

            try {        Bitmap bitmap = BitmapFactory.decodeStream((inputStream) new URL(                "http://xyz.com/a/f/a.png")                .getContent());        tran_btn_skip.setimageBitmap(bitmap);    } catch (Exception e) {    }

确保您必须授予Internet许可
