需求：隐藏安全性和位置信息下的安全更新二级条目

系统：Android8.1

代码地址：MtkSettings/src/com/android/settings/SecuritySettings.java

java 复制代码

private PreferenceScreen createPreferenceHierarchy() {
....
PreferenceGroup securityStatusPreferenceGroup =
                (PreferenceGroup) root.findPreference(KEY_SECURITY_STATUS);
        final List<Preference> tilePrefs = mDashboardFeatureProvider.getPreferencesForCategory(
            getActivity(), getPrefContext(), getMetricsCategory(),
            CategoryKey.CATEGORY_SECURITY);
        int numSecurityStatusPrefs = 0;
        if (tilePrefs != null && !tilePrefs.isEmpty()) {
            for (Preference preference : tilePrefs) {
                if (!TextUtils.isEmpty(preference.getKey())
                    && preference.getKey().startsWith(SECURITY_STATUS_KEY_PREFIX)) {
                    // Injected security status settings are placed under the Security status
                    // category.
                    securityStatusPreferenceGroup.addPreference(preference);
                    numSecurityStatusPrefs++;
                } else {
                    // Other injected settings are placed under the Security preference screen.
                    root.addPreference(preference);
                }
            }
        }
....
}
