我的设置通过一个账户认证器preference的复选框：

I'm settings a preference in a checkbox via an account-authenticator:

Intent settingsIntent = new Intent("android.settings.ACCOUNT_SYNC_SETTINGS");
settingsIntent.putExtra("account", mActiveAccount);
startActivityForResult(settingsIntent, ACCOUNT_COMPLETE);

使用的XML：

<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
android:accountType="com.example.auth"
android:label="@string/auth_label"
android:accountPreferences="@xml/auth_preferences" />

和在auth_ preferences.xml我有：

and in auth_preferences.xml I have:

<?xml version="1.0" encoding="UTF-8" ?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="@string/auth_preferences_general_group" />
<PreferenceScreen android:key="account_settings"
    android:title="@string/auth_preferences_general_details_title" 
    android:summary="@string/auth_preferences_general_details_description">
    <intent android:action="com.example.ACCOUNT_SETUP"
        android:targetPackage="com.example.core"
        android:targetClass="com.example.authentication.AuthenticatorAccountOptions" />
</PreferenceScreen>
<PreferenceCategory android:title="@string/auth_preferences_data_sync_group" >
    <CheckBoxPreference
          android:key="checkbox_pref"
          android:title="@string/auth_preferences_data_sync_syncwidget_title" 
          android:summary="@string/auth_preferences_data_sync_syncwidget_description"
          android:defaultValue="true"
          android:persistent="true" />  
</PreferenceCategory>   

但我不能当我尝试访问的主要code此复选框preferences并检索它：

But I'm unable to access this checkbox preferences in the main code when I try and retrieve it :

SharedPreferences prefs = context.getSharedPreferences(PREFERENCES_NAME, Context.MODE_PRIVATE);
boolean isChecked = prefs.getBoolean("checkbox_pref", true);

任何人都知道的帐户身份验证基于preferences可以访问？

Anyone know where the account-authenticator based preferences can be accessed from?

推荐答案

在根据 auth_ preferences.xml 的活动所做的更改将保存到 com.android.settings_ preferences.xml ，它不能使用你的应用程序的 getShared preferences（文件，环境）访问。我找到共同的解决办法是引发新 preferenceActivity 帐户preferences代替。

The changes made in the Activity based on auth_preferences.xml are saved to com.android.settings_preferences.xml and it can't be accessed using your application's getSharedPreferences(file, context). Common solution I found is to trigger a new PreferenceActivity in account preferences instead.
