android - 膨胀类 com.facebook.widget.LoginButton 时出错

Question

我使用 3.0 文档中的步骤构建了 Facebook 集成。当我使用 Eclispe 将应用程序部署到手机时，它运行良好；但是，当我导出应用程序以将其上传到商店并侧面加载 apk 时，它会失败并出现以下错误。当我导出 SDK 时，SDK 就在那里并已加载。关于我哪里出错的任何线索？

这是我尝试过的：

尝试清理我的项目和 FacebookSDK 大约 50 次。
删除了 FacebookSDK 并阅读了 3 次。

我已经尝试了在互联网上可以找到的所有内容，但无法弄清楚问题所在。

FacebookSdk.sdkInitialize(getApplicationContext());

这个在 setContentView 之前

  setContentView(R.layout.activity_home);

如果您使用的是 Facebook SDK 4.x，请注意包名称已更改。下雪了com.facebook.login.widget.LoginButton

score 6 · Accepted Answer

我收到此错误是因为我在 sdkInitialize 之前设置了内容视图。入门指南对此有评论。

https://developers.facebook.com/docs/android/getting-started#androidstudio

@Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     FacebookSdk.sdkInitialize(getApplicationContext());
     // Initialize the SDK before executing any other operations,
     // especially, if you're using Facebook UI elements.
}

所以我的代码现在看起来像这样：

@Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     FacebookSdk.sdkInitialize(getApplicationContext());
     setContentView(R.layout.activity_main);
}

我遇到了同样的错误，我刚刚清理了我的项目（facebook sdk 和当前项目）并解决了。

您必须在 setContentView 之前初始化 facebook SDK，因此在 setContentView 正上方添加以下行

FacebookSdk.sdkInitialize(getApplicationContext());

After add Facebook as a module you have to add it to your dependencies in Gradle, adding the next line into dependencies block:

compile project(':facebook')

I hope it can help.

我发现解决此问题的唯一方法是将整个 SDK 放入我的项目中。现在它起作用了。不是首选的解决方案，但它有效。

即使我尝试在模拟器中运行它，我也遇到了同样的错误。

我的问题与我将 Facebook Sdk 添加到构建路径而不是在“属性”选项卡中添加项目更相关。我从另一个 stackoverflow 答案中得到了答案

只需初始化 FacebookSdk.sdkInitialize(getApplicationContext()); 在您的应用程序类中。因为 Application 类甚至在你的活动被初始化之前就已经初始化了。

这样做：

公共类 ApplicationController 扩展应用程序{

@Override
public void onCreate() {
    super.onCreate();
    FacebookSdk.sdkInitialize(getApplicationContext());
}

}

一种解决方案是将 Facebook SDK 的路径添加到项目中的“project.properties”。

喜欢：

android.library.reference.1=../libfacebook/facebook-android-sdk-3.0.1/facebook

以防万一..如果有人仍然需要它，请仅清理 facebook 项目，然后将其作为库添加回您的项目中。这解决了我的问题

score 0 · Accepted Answer

我也有同样的错误，只是用 android-support-v13.jar 替换 android-support-v4.jar 解决了这个问题。

score 0 · Accepted Answer

如果您在 Properties->Android 中将 facebook 库添加到您的应用程序，您应该删除 facebooksdk 路径/bin/facebook.jar 中的 facebook.jar。在eclipse中链接时会导致错误。然后你清理你的 facebook sdk 和你的应用程序。我希望工作正常。

我尝试以编程方式创建LoginButton的实例，例如

LoginButton loginButton = new LoginButton(this);

并将其添加到LinearLayout

    fbLoginButton = (LinearLayout) findViewById(R.id.fb_login_view);
    fbLoginButton.addView(loginButton);

这是我的布局 xml 的一瞥

<LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="40dip"
            android:id="@+id/fb_login_view"
            android:layout_centerInParent="true"
            android:layout_gravity="center_horizontal"
            android:text="connect_with_facebook"/>

这当然是遵循@Lalit Kumar 的回答建议的编辑让我知道我是否遗漏了什么。
