在facebook登录成功后开始新的活动

我一直试图通过facebook集成成功登录尝试启动新活动，但是当记录引脚后按下登录按钮时，它返回到登录按钮所在的相同活动 .

我已经有了转移到下一个活动的意图，但它似乎没有对登录成功做出任何响应 .

这是我的代码（抱歉我很久以来一直在这里不整洁）：

import android.content.Intent;

    public class userlogin extends FragmentActivity {

        LoginButton loginButton; //The Facebook login button
        TextView loginstatus;
        CallbackManager callbackManager;
        private AccessToken accessToken;


        @Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                FacebookSdk.sdkInitialize(getApplicationContext());
                setContentView(R.layout.activity_userlogin);
                loginButton = (LoginButton) findViewById(R.id.fb_login_button);
                loginstatus = (TextView)findViewById(R.id.loginstatus);
                callbackManager = CallbackManager.Factory.create();
                loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {

        // **Description: If the user cancels the login before it is completed a message will
        //                be shown to let them know that they are not logged in
        //**Parameters:

            public void onSuccess(LoginResult loginResult) {
            loginstatus.setText("Login Success");
            accessToken = loginResult.getAccessToken();

            Toast.makeText(userlogin.this, "Eureka", Toast.LENGTH_LONG).show();
            GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {


                public void onCompleted(JSONObject object, GraphResponse response) {
                    Log.d("FB", "complete");
                    Log.d("FB", object.optString("name"));
                    Log.d("FB", object.optString("link"));
                    Log.d("FB", object.optString("id"));
                    Log.d("FB", object.optString("gender"));
                    TextView Username;
                    Username = (TextView) findViewById(R.id.loginstatus);
                    String id = object.optString("id");
                    String name = object.optString("name");
                    Username.setText("Welcome:" + name);
                    ImageView userPhoto = (ImageView) findViewById(R.id.facebookuserPortrait);
                    String i = "http://graph.facebook.com/" + id + "/picture?type=large";
                    Glide.with(userlogin.this).load(i).override(350, 350).into(userPhoto);
                    Intent intent = new Intent(userlogin.this, AlertsandPlanning.class);
                        startActivity(intent);


                }

                // **Description: If the user cancels the login before it is completed a message will
                //                be shown to let them know that they are not logged in

                public void onCancel() {
                    loginstatus.setText("Login Canceled");
                }

                // **Description: If the user has an error during the login before it is completed
                //                a message will be shown to let them know that they are not logged in
                //**Parameters: FacebookException: an error transpoding if the login fails
                //**
                //**Precondition: loginButton must have been clicked first
                //**
                //**throws: Exception
                //** returns: a textView that displays a message
                public void onError(FacebookException exception) {
                    loginstatus.setText("Something went wrong \n+" +
                            "Check your credentials and try again");

                }
            });
        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException error) {

        }

        protected void onActivivityResult(int requestCode, int resultCode, Intent data) {
            userlogin.super.onActivityResult(requestCode, resultCode, data);
            callbackManager.onActivityResult(requestCode, resultCode, data);
        }


    });
}

}

我很欣赏任何有用的见解，我可以从头开始讨论这项活动，如果似乎没有任何工作可以再试一次 .

重申此问题：单击“继续使用Facebook”按钮，显示的下一个活动是userlogin活动，而不是AlertsandPlanning活动 .
