我通过帐户验证器在复选框中设置首选项:
Intent settingsIntent = new Intent("android.settings.ACCOUNT_SYNC_SETTINGS");
settingsIntent.putExtra("account", mActiveAccount);
startActivityForResult(settingsIntent, ACCOUNT_COMPLETE);
使用以下 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" />
在 auth_preferences.xml 我有:
<?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>
但是当我尝试检索它时,我无法在主代码中访问此复选框首选项:
SharedPreferences prefs = context.getSharedPreferences(PREFERENCES_NAME, Context.MODE_PRIVATE);
boolean isChecked = prefs.getBoolean("checkbox_pref", true);
任何人都知道可以从哪里访问基于帐户身份验证器的首选项?
