我正在制作我的应用程序，我需要从 Facebook 用户那里获取一些信息，我有性别和语言环境，但我不知道如何获取安装了该应用程序的朋友。到目前为止，这是我的代码：
public class FacebookUser {
private String gender, locale;
private FirebaseUser user;
private FirebaseAuth auth;
private Context context;
public FacebookUser(final Context context){
gender=null;
locale=null;
this.context=context;
auth=FirebaseAuth.getInstance();
user=auth.getCurrentUser();
}
public void createUser(){
FacebookSdk.sdkInitialize(context);
GraphRequest request = GraphRequest.newMeRequest(AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
try{
Log.e("RESPONSE: ",response.getRawResponse());
gender = object.getString("gender");
locale = object.getString("locale");
User currentUser = new User(user.getDisplayName(), user.getEmail(),locale, gender, null,User.UNDEFINED, CuboRubik.UNDEFINED, 0, 0 ,0.00000001F,context);
User.putUserInShared(currentUser, context);
AddToDatabase addToDatabase = new AddToDatabase(context);
addToDatabase.createUser(currentUser, context);
}catch(JSONException e){
e.printStackTrace();
}
}
});
Bundle bundle = new Bundle();
bundle.putString("fields", "locale,gender");
request.setParameters(bundle);
request.executeAsync();
}
这是获取朋友列表的尝试...
private void friendGraphRequest(String friendListId){
final String graphPath = "/"+friendListId+"/members/";
AccessToken token = AccessToken.getCurrentAccessToken();
GraphRequest request = new GraphRequest(token, graphPath, null, HttpMethod.GET, new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse graphResponse) {
JSONObject object = graphResponse.getJSONObject();
try {
JSONArray arrayOfUsersInFriendList= object.getJSONArray("data");
/* Do something with the user list */
/* ex: get first user in list, "name" */
JSONObject user = arrayOfUsersInFriendList.getJSONObject(0);
String usersName = user.getString("name");
Log.e("USERNAME: ",""+usersName);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle param = new Bundle();
param.putString("fields", "name");
request.setParameters(param);
request.executeAsync();
}
我知道有些事情是错误的，但也许我可以使用其中的一些代码。谢谢！
