Android Facebook SDK-膨胀类com.Facebook.login.widget.LoginButton时出错,android,facebook,sdk,facebook-sdk-4.0,Android,Facebook,Sdk,Facebook Sdk 4.0,我刚刚在我的应用程序中安装了Facebook SDK。现在我想显示FB登录按钮，现在我得到了这个错误： android.view.InflateException: Binary XML file line #33: Error inflating class com.facebook.login.widget.LoginButton java.lang.NullPointerException at java.util.concurrent.ConcurrentHashMap

我刚刚在我的应用程序中安装了Facebook SDK。现在我想显示FB登录按钮，现在我得到了这个错误：

android.view.InflateException: Binary XML file line #33: Error inflating class com.facebook.login.widget.LoginButton

java.lang.NullPointerException

这是非常奇怪的，因为我已经可以看到我的手机上的FB按钮。我可以看到该活动1秒，然后它崩溃

这是xml：

请帮帮我。多谢各位

编辑

我也得到了这个错误：

android.view.InflateException: Binary XML file line #33: Error inflating class com.facebook.login.widget.LoginButton

java.lang.NullPointerException
        at java.util.concurrent.ConcurrentHashMap.containsKey(ConcurrentHashMap.java:911)
        at com.facebook.internal.Utility.queryAppSettings(Utility.java:825)
        at com.facebook.login.widget.LoginButton$1.run(LoginButton.java:489)

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587)
        at java.lang.Thread.run(Thread.java:841)
他们指出了这个代码：

在LoginButton.java中：

private void checkToolTipSettings() {
    switch (toolTipMode) {
        case AUTOMATIC:
            // kick off an async request
            final String appId = Utility.getMetadataApplicationId(getContext());
            FacebookSdk.getExecutor().execute(new Runnable() {
                @Override
                public void run() {
                    final FetchedAppSettings settings = Utility.queryAppSettings(appId, false);
                    getActivity().runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            showToolTipPerSettings(settings);
                        }
                    });
                }
            });
            break;
        case DISPLAY_ALWAYS:
            String toolTipString = getResources().getString(
                    R.string.com_facebook_tooltip_default);
            displayToolTip(toolTipString);
            break;
        case NEVER_DISPLAY:
            break;
    }
}
在Utility.java中：

// main thread.
public static FetchedAppSettings queryAppSettings(
        final String applicationId,
        final boolean forceRequery) {
    // Cache the last app checked results.
    if (!forceRequery && fetchedAppSettings.containsKey(applicationId)) {
        return fetchedAppSettings.get(applicationId);
    }

    JSONObject response = getAppSettingsQueryResponse(applicationId);
    if (response == null) {
        return null;
    }

    return parseAppSettingsFromJSON(applicationId, response);
}
您很抱歉，Facebook SDK未导入。尝试按照开发者网站上的说明进行操作，因为自您观看我的视频教程以来，这些说明可能已经发生了变化。

将此代码放入Manifest.xml中的应用程序标记中

        <activity
            android:name="com.facebook.CustomTabActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />

                <data android:scheme="@string/fb_login_protocol_scheme" />
            </intent-filter>
        </activity>
它对我起了作用

我想我不明白。你能发一些代码吗？我不知道如何按照他们的指示导入。这就是为什么我遵循你的教程。如果我按照他们的指示去做，我不知道把facebook sdk文件夹放在哪里。它不是用.jar格式制作的，我也相信已经导入了fcebook SDK，因为我可以在activity.java中导入facebook，也可以在xml中使用facebook小部件。我甚至可以看到facebook的蓝色登录按钮。
