Struct droid_wrap::android::content::ContextWrapper

pub struct ContextWrapper { /* private fields */ }

• Context 的代理实现，它只是将其所有调用委托给另一个 Context。可以创建子类来修改行为，而无需更改原始 Context。

Implementations

impl ContextWrapper

pub fn get_class_loader(&self) -> ClassLoader

返回可用于查询此包中的类的类加载器。

pub fn send_broadcast(&self, intent: &Intent)

将给定的意图广播给所有感兴趣的 BroadcastReceiver。此调用是异步的；它会立即返回，您将在接收器运行时继续执行。接收器不会传播任何结果，接收器也无法中止广播。如果您想允许接收器传播结果或中止广播，则必须使用 sendOrderedBroadcast(Intent, String) 发送有序广播。有关 Intent 广播的更多信息，请参阅 BroadcastReceiver。 intent 要广播的 Intent；与此 Intent 匹配的所有接收器都将收到广播。

pub fn get_class_loader(&self) -> ClassLoader

• 返回可用于查询此包中的类的类加载器。

pub fn send_broadcast(&self, intent: &Intent)

• 将给定的意图广播给所有感兴趣的 BroadcastReceiver。此调用是异步的；它会立即返回，您将在接收器运行时继续执行。接收器不会传播任何结果，接收器也无法中止广播。如果您想允许接收器传播结果或中止广播，则必须使用 sendOrderedBroadcast(Intent, String) 发送有序广播。有关 Intent 广播的更多信息，请参阅 BroadcastReceiver。
• intent 要广播的 Intent；与此 Intent 匹配的所有接收器都将收到广播。

pub fn start_activity(&self, intent: &Intent)

• 与 startActivity(Intent, Bundle) 相同，但未指定任何选项。
• intent 要启动的活动的描述。
• 抛出：ActivityNotFoundException – `

pub fn get_package_name(&self) -> String

• 返回此应用程序包的名称。

pub fn get_base_package_name(&self) -> String

• 返回此上下文所派生自的基础上下文的名称。这与 getOpPackageName() 相同，除非系统组件加载到其他应用进程中，在这种情况下 getOpPackageName() 将是该进程中主软件包的名称（以便应用操作 uid 验证可以使用该名称）。

pub fn get_op_package_name(&self) -> String

• 返回应用于此上下文中的 android.app.AppOpsManager 调用的包名称，以便 app ops manager 的 uid 验证可以使用该名称。这通常不适用于第三方应用程序开发人员。

pub fn get_attribution_tag(&self) -> Option<String>

• 归因可用于复杂的应用中，以在逻辑上区分应用的各个部分。例如，博客应用可能还内置有即时通讯应用。在这种情况下，每个子功能可以使用两个单独的标签。
• 返回：此上下文所针对的归因标签，如果这是默认标签，则返回 null。

pub fn get_package_resource_path(&self) -> String

• 返回此上下文的主要 Android 包的完整路径。Android 包是一个 ZIP 文件，其中包含应用程序的主要资源。注意：这通常对应用程序没有用，因为它们不应直接访问文件系统。
• 返回：String 资源路径。

pub fn get_package_code_path(&self) -> String

• 返回此上下文的主要 Android 包的完整路径。Android 包是一个 ZIP 文件，其中包含应用程序的主要代码和资产。
• 注意：这通常对应用程序没有用，因为它们不应直接访问文件系统。
• 返回：String 代码和资产的路径。

pub fn get_system_service(&self, name: String) -> Option<Object>

• 按名称返回系统级服务的句柄。返回对象的类因请求的名称而异。当前可用的名称为：
• WINDOW_SERVICE (“window”)
• 您可以在顶级窗口管理器中放置自定义窗口。返回的对象是 WindowManager。只能从可视上下文（例如 Activity 或使用 createWindowContext(int, Bundle) 创建的上下文）中获取，这些上下文会根据屏幕区域的配置和可视边界进行调整。
• LAYOUT_INFLATER_SERVICE (“layout_inflater”)
• android.view.LayoutInflater 用于在此上下文中填充布局资源。只能从可视上下文（例如 Activity 或使用 createWindowContext(int, Bundle) 创建的上下文）获取，这些上下文会根据屏幕区域的配置和可视边界进行调整。
• ACTIVITY_SERVICE (“activity”)
• 用于与系统全局活动状态交互的 ActivityManager。
• WALLPAPER_SERVICE (“wallpaper”)
• android.service.wallpaper.WallpaperService 用于在此上下文中访问壁纸。只能从可视上下文（例如 Activity 或使用 createWindowContext(int, Bundle) 创建的上下文）获取，这些上下文会根据屏幕区域的配置和可视边界进行调整。
• POWER_SERVICE (“power”)
• 一个用于控制电源管理的android.os.PowerManager。
• ALARM_SERVICE (“alarm”)
• 一个 Android 应用程序 AlarmManager，用于在您选择的时间接收意图。
• NOTIFICATION_SERVICE (“notification”)
• android.app.NotificationManager，用于通知用户后台事件。
• KEYGUARD_SERVICE (“keyguard”)
• 一个用于控制键盘锁的 android.app.KeyguardManager。
• LOCATION_SERVICE (“location”)
• android.location.LocationManager 用于控制位置（例如 GPS）更新。
• SEARCH_SERVICE (“search”)
• 一个用于处理搜索的android.app.SearchManager。
• VIBRATOR_MANAGER_SERVICE (“vibrator_manager”)
• android.os.VibratorManager，用于访问设备振动器、与各个振动器交互以及在多个振动器上播放同步效果。
• VIBRATOR_SERVICE (“vibrator”)
• 一个android.os.Vibrator，用于与振动器硬件进行交互。
• CONNECTIVITY_SERVICE (“connectivity”)
• 用于处理网络连接管理的 ConnectivityManager。
• IPSEC_SERVICE (“ipsec”)
• IpSecManager 用于管理套接字和网络上的 IPSec。
• WIFI_SERVICE (“wifi”)
• 用于管理 Wi-Fi 连接的 WifiManager。在 Android 7 之前的版本中，应仅从应用上下文中获取它，而不能从任何其他派生上下文中获取它，以避免调用过程中出现内存泄漏。
• WIFI_AWARE_SERVICE (“wifiaware”)
• WifiAwareManager 用于管理 Wi-Fi Aware 发现和连接。
• WIFI_P2P_SERVICE (“wifip2p”)
• WifiP2pManager 用于管理 Wi-Fi Direct 连接。
• INPUT_METHOD_SERVICE (“input_method”)
• 用于管理输入方法的 InputMethodManager。
• UI_MODE_SERVICE (“uimode”)
• 一个用于控制 UI 模式的 android.app.UiModeManager。
• DOWNLOAD_SERVICE (“download”)
• 用于请求 HTTP 下载的 android.app.DownloadManager
• BATTERY_SERVICE (“batterymanager”)
• 用于管理电池状态的 android.os.BatteryManager
• JOB_SCHEDULER_SERVICE (“taskmanager”)
• 一个用于管理计划任务的android.app.job.JobScheduler
• NETWORK_STATS_SERVICE (“netstats”)
• 用于查询网络使用情况统计数据的 NetworkStatsManager。
• HARDWARE_PROPERTIES_SERVICE (“hardware_properties”)
• 用于访问硬件属性的 android.os.HardwarePropertiesManager。
• DOMAIN_VERIFICATION_SERVICE (“domain_verification”)
• android.content.pm.verify.domain.DomainVerificationManager，用于访问 Web 域批准状态。
• DISPLAY_HASH_SERVICE (“display_hash”)
• android.view.displayhash.DisplayHashManager 用于管理显示哈希。
• 注意：通过此 API 获取的系统服务可能与获取它们的上下文密切相关。一般来说，不要在各种不同的上下文（活动、应用程序、服务、提供商等）之间共享服务对象。
• 注意：PackageManager.isInstantApp() 返回 true 的免安装应用无法访问以下系统服务：DEVICE_POLICY_SERVICE、FINGERPRINT_SERVICE、KEYGUARD_SERVICE、SHORTCUT_SERVICE、USB_SERVICE、WALLPAPER_SERVICE、WIFI_P2P_SERVICE、WIFI_SERVICE、WIFI_AWARE_SERVICE。对于这些服务，此方法将返回 null。通常，如果您以免安装应用的形式运行，则应始终检查此方法的结果是否为 null。
• 注意：在实现此方法时，请记住可以在较新的 Android 版本中添加新服务，因此如果您只是在寻找上面提到的明确名称，请确保在您无法识别该名称时返回 null — 如果您抛出 RuntimeException 异常，您的应用可能会在新的 Android 版本上中断。
• 返回：如果名称不存在则返回 null。
• name 所需服务的名称。

Methods from Deref<Target = GlobalRef>

pub fn as_obj(&self) -> &JObject<'static>

Get the object from the global ref

This borrows the ref and prevents it from being dropped as long as the JObject sticks around.

Methods from Deref<Target = JObject<'static>>

pub fn as_raw(&self) -> *mut _jobject

Returns the raw JNI pointer.
