我正在关注这个例子 android:load svg file from web and show it on image view
这是我正在使用的代码。它基本上是他们正在做的事情的副本。但我一直得到错误，找不到元素。
class FetchImageTask extends AsyncTask<Void, Void, Drawable> {
protected Drawable doInBackground(Void... urls) {
try {
//URL url = new URL(imageTeam);
final URL url = new URL("http://upload.wikimedia.org/wikipedia/commons/e/e8/Svg_example3.svg");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
InputStream inputStream = urlConnection.getInputStream();
SVG svg = SVGParser.getSVGFromInputStream(inputStream);
Drawable drawable = svg.createPictureDrawable();
return drawable;
} catch (Exception e) {
Log.e("MainActivity", e.getMessage(), e);
}
return null;
}
protected void onPostExecute(Drawable drawable) {
if (drawable != null) {
team1.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
team1.setImageDrawable(drawable);
team1.setVisibility(View.VISIBLE);
}
}
}
这是我的错误日志。
