Settings应用中提供多类设置菜单入口每个菜单内又有各模块功能的实现。
那么各个模块基于Settings 基础的界面Fragment去实现UI层层按不同业务进行封装继承实现子类
DashboardFragmentSettingsPreferenceFragment
功能设置页中的菜单又是通过Controller去实现业务并进行UI动态更新控制。 代码
基于 Android U 平台的实现进行介绍。
公用基类
DashboardFragment
packages/apps/Settings/src/com/android/settings/dashboard/DashboardFragment.java
package com.android.settings.dashboard;/*** Base fragment for dashboard style UI containing a list of static and dynamic setting items.*/
public abstract class DashboardFragment extends SettingsPreferenceFragmentimplements CategoryListener, Indexable, PreferenceGroup.OnExpandButtonClickListener,BasePreferenceController.UiBlockListener {public static final String CATEGORY category;private static final String TAG DashboardFragment;private static final long TIMEOUT_MILLIS 50L;/*** Get a list of {link AbstractPreferenceController} for this fragment.*/protected ListAbstractPreferenceController createPreferenceControllers(Context context) {return null;} 模块案例
继承关系自上而下底层是父类除了MobileNetwork其他都是抽象类直到Fragment
MobileNetworkSettings --- 移动网络设置AbstractMobileNetworkSettingsRestrictedDashboardFragmentDashboardFragmentSettingsPreferenceFragmentInstrumentedPreferenceFragment -- /com/android/settings/core/ObservablePreferenceFragment -- /frameworks/base/packages/SettingsLibPreferenceFragmentCompat -- classes.jar/androidx.preferenceFragment AbstractMobileNetworkSettings 是一个抽象类用于提供移动网络设置相关的基本功能和行为。 RestrictedDashboardFragment 是在DashboardFragment的基础上添加了一些限制或额外的安全措施以限制用户对某些设置或操作的访问或更改。可能会对一些敏感的设置进行限制例如网络设置、安全设置等。也可能会对某些功能进行权限控制只允许特定用户访问。 DashboardFragment 是基础的仪表盘样式 UI Fragment用于显示静态和动态的设置项列表。通常不会加入对设置的限制而是专注于提供用户友好的设置界面和功能。可能包含一些基本的设置项处理和展示逻辑以便用户能够轻松地进行配置和操作。 MobileNetworkSettings 移动网络设置界面逻辑
