Android的SkImageDe codeR ::厂返回null错误 [英] Android SkImageDecoder::Factory returned null Error

问题描述

我想从URL加载图像的ImageView的，但出现错误： SkImageDe codeR ::厂返回null。我该如何解决这个问题？

这是我的code：

 私有类LoadImageFromURL扩展的AsyncTask＆LT;字符串，太虚，位图＆GT; {
        ImageView的bitmapImgView;
        公共LoadImageFromURL（ImageView的bmImgView）{
            bitmapImgView = bmImgView;
        }

        @覆盖
        受保护的位图doInBackground（字符串... PARAMS）{
            // TODO自动生成方法存根
            串urlStr = PARAMS [0];
            位图IMG = NULL;
            尝试 {
                网址URL =新的URL（urlStr）;
                InputStream中的InputStream = url.openConnection（）的getInputStream（）。
                //选项bmFactoryOpt =新的选项（）;
                //bmFactoryOpt.inJustDe$c$cBounds = FALSE;
                IMG = BitmapFactory.de codeStream（InputStream的）;
            }赶上（MalformedURLException异常E）{
                // TODO自动生成的catch块
                e.printStackTrace（）;
            }赶上（IOException异常E）{
                // TODO自动生成的catch块
                e.printStackTrace（）;
            }
            返回IMG;
        }

        @覆盖
        保护无效onPostExecute（位图位图）{
            bitmapImgView.setImageBitmap（位）;
        }
    }
 

解决方案

解决。更改code到这一点。

  @覆盖
        受保护的位图doInBackground（字符串... PARAMS）{
            // TODO自动生成方法存根
            串urlStr = PARAMS [0];
            位图IMG = NULL;

            HttpClient的客户端=新DefaultHttpClient（）;
            HTTPGET请求=新HTTPGET（urlStr）;
            HTT presponse响应;
            尝试 {
                响应=（Htt的presponse）client.execute（要求）;
                HttpEntity实体= response.getEntity（）;
                BufferedHttpEntity bufferedEntity =新BufferedHttpEntity（实体）;
                InputStream中的InputStream = bufferedEntity.getContent（）;
                IMG = BitmapFactory.de codeStream（InputStream的）;
            }赶上（ClientProtocolException E）{
                // TODO自动生成的catch块
                e.printStackTrace（）;
            }赶上（IOException异常E）{
                // TODO自动生成的catch块
                e.printStackTrace（）;
            }
            返回IMG;
        }
 

I'm trying to load an image from URL to an ImageView but the error occurs: SkImageDecoder::Factory returned null. How can I fix it?

here is my code :

private class LoadImageFromURL extends AsyncTask<String, Void, Bitmap>{
        ImageView bitmapImgView;
        public LoadImageFromURL(ImageView bmImgView){
            bitmapImgView = bmImgView;
        }

        @Override
        protected Bitmap doInBackground(String... params) {
            // TODO Auto-generated method stub
            String urlStr = params[0];
            Bitmap img = null;
            try {
                URL url = new URL(urlStr);
                InputStream inputStream = url.openConnection().getInputStream();
                //Options bmFactoryOpt = new Options();
                //bmFactoryOpt.inJustDecodeBounds = false;
                img = BitmapFactory.decodeStream(inputStream);          
            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }       
            return img;
        }

        @Override
        protected void onPostExecute(Bitmap bitmap){
            bitmapImgView.setImageBitmap(bitmap);
        }
    }

解决方案

Solved. Change the code to this.

@Override
        protected Bitmap doInBackground(String... params) {
            // TODO Auto-generated method stub
            String urlStr = params[0];
            Bitmap img = null;

            HttpClient client = new DefaultHttpClient();
            HttpGet request = new HttpGet(urlStr);
            HttpResponse response;
            try {
                response = (HttpResponse)client.execute(request);           
                HttpEntity entity = response.getEntity();
                BufferedHttpEntity bufferedEntity = new BufferedHttpEntity(entity);
                InputStream inputStream = bufferedEntity.getContent();
                img = BitmapFactory.decodeStream(inputStream);
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return img;
        }
