使用 Facebook SDK 4.0.1 膨胀 class com.facebook.widget.LoginButton 时出错
Error inflating class com.facebook.widget.LoginButton with Facebook SDK 4.0.1
我知道这是一个很常见的问题，但是我已经通读了所有堆栈溢出问题，但没有找到答案。
我正在尝试使用通过 Gradle 添加的 Facebook SDK 4.0.1 集成 Facebook 登录按钮，但出现以下错误。

我可以在 Android Studio 中看到 LoginButton class，所以它可以工作

在 facebook sdk 4.0.1 中，LoginButton class 不在 com.facebook.widget 包内。它在 com.facebook.login.widget 包内。所以你的 xml 声明应该是这样的：
<com.facebook.login.widget.LoginButton
android:id="@+id/connectWithFbButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_gravity="center_horizontal"
android:text=" connect_with_facebook" />
在 Facebook 文档上，该包已过时。
对于新版本 4 及更高版本，按钮的新包是 com.facebook.login.widget.LoginFacebook.
依赖关系：
compile 'com.facebook.android:facebook-android-sdk:4.5.0'
activity_login.xml:
<com.facebook.login.widget.LoginButton
android:id="@+id/connectWithFbButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_gravity="center_horizontal" />
尽情享受吧！
嘿，朋友，你的所有代码都是正确的。按照以下说明操作。
放FacebookSdk.sdkInitialize(getApplicationContext());
在 setContentView() 之前；
并在您的 xml 父布局中放置以下行
xmlns:facebook="http://schemas.android.com/apk/res-auto"
喜欢，
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:facebook="http://schemas.android.com/apk/res-auto"

android:layout_centerInParent="true"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="30dp"
android:layout_marginTop="30dp" />
</RelativeLayout>
Caused by: The SDK has not been initialized, make sure to call
FacebookSdk.sdkInitialize() first.
确保在设置内容视图之前初始化了 facebook SDK。
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_main);
请确保您的 Facebook SDK 在 setContentView 之前已初始化
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_main);
仅在您应用的应用程序中添加此方法class::
FacebookSdk.sdkInitialize(getApplicationContext());
AppEventsLogger.activateApp(this);
之前：onCreate 中的 setContentView Activity。
在依赖导入中：
compile 'com.facebook.android:facebook-android-sdk:[4,5)' or smaller
尽情享受吧:)
SDK尚未初始化，请务必先调用FacebookSdk.sdkInitialize()
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(this.getApplicationContext());
setContentView(R.layout.activity_main1);
}
FacebookSdk.sdkInitialize();已弃用。不要再使用它了。
并在此处按照本教程进行操作：
https://developers.facebook.com/docs/facebook-login/android
不使用 com.facebook.login.widget.LoginButton.
尝试使用以下代码使用普通按钮：
/**
* Setup Facebook Login Button
*/
@Override
public void setupFacebookLoginButton() {
Button btnFacebook = mActivityReference.findViewById(R.id.btnFacebook);
Drawable leftDrawable = AppCompatResources.getDrawable(mActivityReference, R.drawable.ic_facebook_icon);
btnFacebook.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);
// Start Facebook integration
LoginManager fbLoginManager = com.facebook.login.LoginManager.getInstance();
mFaceCallbackManager = CallbackManager.Factory.create();
fbLoginManager.registerCallback(mFaceCallbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
// Your accessToken is here
}
@Override
public void onCancel() {
Log.d("asd", "asd");
}
@Override
public void onError(FacebookException e) {
Log.d("asd", "asd");
}
});
btnFacebook.setOnClickListener(v -> fbLoginManager.logInWithReadPermissions(
mActivityReference,
Arrays.asList("email", "public_profile", "user_birthday")));
}
/**
* Facebook Call Back
*
* @param requestCode request code
* @param resultCode result code
* @param data data
*/
@Override
public void facebookCallBack(int requestCode, int resultCode, Intent data) {
if (mFaceCallbackManager != null) {
mFaceCallbackManager.onActivityResult(requestCode, resultCode, data);
}
}
不要忘记在 android 清单中添加 android 应用程序 ID
应用程序 xml 标签
<application>
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id"/>
</application>
