Javascript Facebook登录android应用程序

大家好，我正试图在我的android应用程序中登录Facebook，我想将Facebook用户名和Facebook id传递给另一个活动，但我不知道怎么做。无论如何，我的登录不起作用，我的应用程序在我打开时关闭。以下是我的活动：

import android.content.Context;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;

import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.login.LoginManager;
import com.facebook.login.LoginResult;
import com.facebook.login.widget.LoginButton;


public class LoginActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.container, new PlaceholderFragment())
                    .commit();
        }
    }


    /**
     * A placeholder fragment containing a simple view.
     */
    public class PlaceholderFragment extends Fragment {

        CallbackManager callbackManager;
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            FacebookSdk.sdkInitialize(getApplicationContext());

            callbackManager = CallbackManager.Factory.create();

            LoginManager.getInstance().registerCallback(callbackManager,
                    new FacebookCallback<LoginResult>() {
                        @Override
                        public void onSuccess(LoginResult loginResult) {
                            // App code
                        }

                        @Override
                        public void onCancel() {
                            // App code
                        }

                        @Override
                        public void onError(FacebookException exception) {
                            // App code
                        }
                    });
        }
        public PlaceholderFragment() {
        }

        public View onCreateView(
                LayoutInflater inflater,
                ViewGroup container,
                Bundle savedInstanceState) {
            View view = inflater.inflate(R.layout.activity_login, container, false);

            LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
            loginButton.setReadPermissions("user_friends");
            // If using in a fragment
            loginButton.setFragment(this);
            // Other app specific specialization

            // Callback registration
            CallbackManager callbackManager = null;
            loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(LoginResult loginResult) {
                    // App code
                }

                @Override
                public void onCancel() {
                    // App code
                }

                @Override
                public void onError(FacebookException exception) {
                    // App code
                }
            });

            return view;

        }


    }
}

logcat中是否有任何错误消息告诉您登录失败？请查看我的编辑@LeoLinit无论如何都不起作用，logcat是相同的，我尝试解决此问题的时间是2周，请帮助我做到这一点，我将把整个项目发布到这里：@LeoLinI发现了一些您可能遗漏的内容，因此我用一个简单的示例编辑了我的答案。现在它给了我以下错误：05-08 15:27:16.894 23498-23498/com.tekinarslan.material.sample E/AndroidRuntime﹕ 致命异常：主java.lang.RuntimeException:无法启动活动组件信息{com.tekinarslan.material.sample/com.tekinarslan.material.sample.LoginActivity}:java.lang.ClassCastException:android.widget.Button无法转换为android.app.ActivityThread.performLaunchActivity上的com.tekinarslan.material.sample.Button（ActivityThread.java:2295）@LeoLinIt的java.lang.ClassCastException，您是否在xml中使用了自定义按钮？
