我的graphrequest似乎工作正常，检索登录Names的用户也没有问题，获取他们的ID也没有任何问题。我正在尝试存储他们的个人资料图片以在我的应用程序中使用（通过将其下载为位图），但似乎无法成功下载。有人可以告诉我我在做什么错吗？
//Run the first time we log into Facebook
//connects everything here
private void firstTimeFBlogin() {
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
Log.i("joe", "Heyyyyo");
try {
String userName = response.getJSONObject().getString("name");
String userID = response.getJSONObject().getString("id");
//String hi2 = response.getJSONObject().getString("first_name");
//String hi3 = response.getJSONObject().getString("gender");
final JSONObject mPicture = object.getJSONObject("picture");
final JSONObject mPictureData = mPicture.getJSONObject("data");
final String mImageUrl = mPictureData.getString("url");
Log.i("joe", "User's Facebook Name: " + userName);
Log.i("joe", ParseUser.getCurrentUser().getUsername());
Log.i("joe", mImageUrl);
Log.i("joe", userID);
ParseUser.getCurrentUser().put("name", userName);
ParseUser.getCurrentUser().put("iUrl", mImageUrl);
ParseUser.getCurrentUser().put("fbID", userID);
ParseUser.getCurrentUser().saveInBackground();
profilePictureRetriever(userID);
} catch (JSONException e) {
Log.i("joe", "Couldn't Succesfully retrieve the stuff...");
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,link,picture");
request.setParameters(parameters);
request.executeAsync();
}
public void profilePictureRetriever(String id) {
Log.i("joe", "Profile Picture Checker");
//Bitmap bitmap = getFacebookProfilePicture(id);
//this is here for test purposes
//tried just maually putting the url in..
Bitmap bm = DownloadImageBitmap("https://graph.facebook.com/849993771766163/picture?type=square");
}
public static Bitmap DownloadImageBitmap(String url) {
Bitmap bm = null;
try {
URL aURL = new URL(url);
URLConnection conn = aURL.openConnection();
conn.connect();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
bm = BitmapFactory.decodeStream(bis);
bis.close();
is.close();
} catch (IOException e) {
Log.e("IMAGE", "Error getting bitmap", e);
}
return bm;
}
}
有另一种/更好的方法可以做到这一点吗？
非常感谢！
最佳答案
我做了这样的事情：
首先，您需要调用GraphRequest API以获取其中API还提供URL of current Profile Picture的用户的所有详细信息。
Bundle params = new Bundle();
params.putString("fields", "id,email,gender,cover,picture.type(large)");
new GraphRequest(token, "me", params, HttpMethod.GET,
new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse response) {
if (response != null) {
try {
JSONObject data = response.getJSONObject();
if (data.has("picture")) {
String profilePicUrl = data.getJSONObject("picture").getJSONObject("data").getString("url");
Bitmap profilePic = getFacebookProfilePicture(profilePicUrl);
// set profilePic bitmap to imageview
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}).executeAsync();
您可以使用此方法从
URL返回从GraphRequest API返回的用户的当前个人资料图片。public static Bitmap getFacebookProfilePicture(String url){
Bitmap bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
return bitmap;
}
希望对您有所帮助！
