答
我希望你先问自己从Facebook的个人资料图片的许可,bcz未经许可facebook不会让你得到任何东西。
loginButton.setReadPermissions("public_profile", "email", "user_friends", "user_education_history", "user_hometown", "user_likes", "user_work_history");
,或者您也可以使用Facebook回调以获取用户的个人资料图片,这样的..
private FacebookCallback<LoginResult> mCallBack = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(final LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
Log.e("response: ", response + "");
try {
String id = object.getString("id").toString();
String email = object.getString("email").toString();
String name = object.getString("name").toString();
String profilePicUrl = "https://graph.facebook.com/" + loginResult.getAccessToken().getUserId() + "/picture?type=large";
Log.d("imageFB", profilePicUrl);
Log.d("FB_ID:", id);
checkFBLogin(id, email, name, profilePicUrl);
} catch (Exception e) {
e.printStackTrace();
}
finish();
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender,birthday,friends,likes,hometown,education,work");
request.setParameters(parameters);
request.executeAsync();
}
我的代码,包括loginButton.setReadPermissions( “电子邮件”, “public_profile”);线。 –
我应该在LoginActivity中使用您的代码还是在LoginActivity后打开的活动? –
在登录活动中使用此代码。并将图像传递给下一个活动。 –
