问题描述

我试图创建一个应用程序，这将允许用户通过他们的Facebook账户登录。我想通过Eclipse中使用新的Facebook SDK 4.1.2。在Eclipse中使用新的SDK，我也跟着<一个href=\"http://stackoverflow.com/questions/29379890/android-facebook-sdk-4-in-eclipse/29400310#29400310\">this教程。我现在可以删除所有来自Facebook的SDK中的错误，而在日食。然后，我开始以下这些步骤为了整合FB 的中使用新的SDK示例应用程序。

I am trying to create an application, which will allow users to sign in via their Facebook accounts. I wanted to use the new Facebook SDK 4.1.2 via eclipse. To use the new SDK in eclipse, I followed this tutorial. I am now able to remove all the errors from the facebook SDK without in eclipse. Then, I started following these steps in order to integrate FB in a sample application using the new SDK.

我已开始进行这样的：

在MainActivity 

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

import com.facebook.CallbackManager;
import com.facebook.FacebookSdk;

public class MainActivity extends FragmentActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        FacebookSdk.sdkInitialize(getApplicationContext());
        if (savedInstanceState == null) {
            getFragmentManager()
                    .beginTransaction()
                    .add(R.id.fragmentParentViewGroup, new FacebookFragment())
                    .commit();
        }
    }




}

activity_main.xml中： 

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             xmlns:tools="http://schemas.android.com/tools"
             android:id="@+id/fragmentParentViewGroup"
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             tools:context=".MyActivity"
             tools:ignore="MergeRootFrame" />

的FacebookFragment： 

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.facebook.CallbackManager;
import com.facebook.FacebookCallback;
import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.login.LoginResult;
import com.facebook.login.widget.LoginButton;

public class FacebookFragment extends Fragment{
    CallbackManager callbackManager;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parentViewGroup,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.facebook_fragment, parentViewGroup, false);
        FacebookSdk.sdkInitialize(getActivity());
        callbackManager = CallbackManager.Factory.create();
        LoginButton loginButton = (LoginButton) rootView.findViewById(R.id.login_button);
        loginButton.setReadPermissions("user_friends");
        // If using in a fragment
       // loginButton.setFragment(this);    
     // Callback registration
        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 rootView;
    }
}

的facebook_fragment.xml： 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    >

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" 
        android:background="#FFFFFF">

       <com.facebook.login.widget.LoginButton
    android:id="@+id/login_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="30dp"
    android:layout_marginBottom="30dp" />   

    </RelativeLayout>

清单： 

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.facbooksdk4test"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.facbooksdk4test.MainActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.Translucent.NoTitleBar" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.facebook.sdk.ApplicationId"
            android:value="@string/facebook_app_id" />

        <activity
            android:name="com.facebook.FacebookActivity"
            android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.Translucent.NoTitleBar" />
    </application>

</manifest>

做上述所有我仍然得到初始化错误后。该报告logcat中：

After doing all the above I am still getting initialization errors. The logcat report:

我不知道我要去的地方错了，还是应该做些什么来解决这个问题。请建议我有什么工作要做，以解决相同的。

I am not sure where I am going wrong, or what should be done to fix the issues. Please suggest me what is to be done to fix the same.

推荐答案

我没有在code 的onActivityResult 办法看到的。它需要适当的SDK的工作流程。

I don't see in your code onActivityResult method. It is required for properly SDK workflow.

您需要将其添加到在MainActivity：

You need to add it to the MainActivity:

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

原因：

这是你的FacebookSDK整合的每个活动和片段
  登录或分享转发应该到的onActivityResult的callbackManager。

Every activity and fragment that you integrate with the FacebookSDK Login or Share should forward onActivityResult to the callbackManager.

您可以在文档中这里找到它。

You can find it in documentation here.
