我想從url下載圖像並將其設置爲運行時在操作欄中的主圖標。我正在使用AsyncTask來執行它,但它似乎沒有改變它。有任何想法嗎?從url設置位圖作爲操作欄主頁圖標在Android中
class getProfilePicture extends AsyncTask<Void, Void, Void> {
protected Void doInBackground(Void... params) {
try {
URL url;
url = new URL("http://www.i2clipart.com/cliparts/2/a/3/2/clipart-fcrc-logo-handshake-2a32.png");
HttpURLConnection conn = (HttpURLConnection) url
.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
image = BitmapFactory.decodeStream(is);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
protected void onPostExecute() {
// TODO: check this.exception
Resources res = getResources();
BitmapDrawable icon = new BitmapDrawable(res, image);
getSupportActionBar().setIcon(icon);
//getSupportActionBar().setLogo(icon);
}
}
