我正在尝试将图像从 URL 加载到 ImageView 但出现错误: SkImageDecoder::Factory 返回空值。我该如何解决?
这是我的代码:
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);
}
}
最佳答案
已解决。把代码改成这样。
@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;
}
