这是我的代码，i am using to get user profile picture，见下文：
authButton.setUserInfoChangedCallback(new LoginButton.UserInfoChangedCallback() {
@Override
public void onUserInfoFetched(GraphUser user) {
try {
if (user != null) {
final String strId = user.getId();
AsyncTask<Void, Void, Bitmap> t = new AsyncTask<Void, Void, Bitmap>(){
protected Bitmap doInBackground(Void... p) {
try {
URL img_value = null;
img_value = new URL("http://graph.facebook.com/"+strId+"/picture");
HttpURLConnection connection = (HttpURLConnection) img_value.openConnection(); HttpURLConnection.setFollowRedirects(HttpURLConnection.getFollowRedirects());
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
bitmap= BitmapFactory.decodeStream(input);
} catch (IOException e) {
Log.d("TAG", "Loading Picture FAILED");
e.printStackTrace();
}
return bitmap;
}
protected void onPostExecute(Bitmap bm){
imageView.setImageBitmap(bitmap);
}
};
t.execute();
我测试了我的URL in web和getting my profile pic，但不知道为什么会发生这种情况，同时尝试以编程方式在ImageView中显示和显示图像！
答案 0 :(得分：0)
最后，我发现easy and smart way获得了User's profile picture，我使用了Facebook SDK中提供的ProfilePictureView功能
AsycTask我的代码to get image from URL，no usage HttpConnection，Bitmap以及其他代码中不再需要...
答案 1 :(得分：-2)
使用Aquery Library，
aQuery.id(R.id.image1).image(your image url);
