以下代码用于svg文件显示为图像视图。。
private class HttpImageRequestTask extends AsyncTask<Void, Void, Drawable> {
@Override
protected Drawable doInBackground(Void... params) {
try {
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;
}
@Override
protected void onPostExecute(Drawable drawable) {
// Update the view
updateImageView(drawable);
}
}
private void updateImageView(Drawable drawable){
if(drawable != null){
// Try using your library and adding this layer type before switching your SVG parsing
mImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
Picasso.with(this)
.placeholder(drawable) //this is optional the image to display while the url image is downloading
.error(Your Drawable Resource) //this is also optional if some error has occurred in downloading the image this image would be displayed
.into(imageView);
}
}
