Android对飞行模式下Wifi和蓝牙的控制通过如下两个数据库中的值控制： airplane_mode_radios、airplane_mode_toggleable_radios，其值保存在Setting数据库Global表中. /** * A comma separated list of radios that need to be disabled when airplane mode * is on. This overrides WIFI_ON and BLUETOOTH_ON, if Wi-Fi and bluetooth are * included in the comma separated list. */ public static final String AIRPLANE_MODE_RADIOS = "airplane_mode_radios";通过注释，可以看出，该值表示在打开飞行模式的时候需要关闭的radios，以逗号分隔。 若需要在打开飞行模式的时候关闭wifi和bluetooth，这该值为”wifi,bluetooth” /** * A comma separated list of radios that should to be disabled when airplane mode * is on, but can be manually reenabled by the user. For example, if RADIO_WIFI is * added to both AIRPLANE_MODE_RADIOS and AIRPLANE_MODE_TOGGLEABLE_RADIOS, then Wifi * will be turned off when entering airplane mode, but the user will be able to reenable * Wifi in the Settings app. * * {@hide} */ public static final String AIRPLANE_MODE_TOGGLEABLE_RADIOS = "airplane_mode_toggleable_radios"; 通过注释，可以看出，该值表示在飞行模式下还能打开的radios(用户可以手动打开),以逗号分隔。 若需要在飞行模式下仍能够开启wifi和bluetooth，这该值为”wifi,bluetooth” Radios列表项: /** * Constant for use in AIRPLANE_MODE_RADIOS to specify Bluetooth radio. */ public static final String RADIO_BLUETOOTH = "bluetooth"; /** * Constant for use in AIRPLANE_MODE_RADIOS to specify Wi-Fi radio. */ public static final String RADIO_WIFI = "wifi"; /** * {@hide} */ public static final String RADIO_WIMAX = "wimax"; /** * Constant for use in AIRPLANE_MODE_RADIOS to specify Cellular radio. */ public static final String RADIO_CELL = "cell"; /** * Constant for use in AIRPLANE_MODE_RADIOS to specify NFC radio. */ public static final String RADIO_NFC = "nfc";默认值配置的位置如下： /frameworks/base/packages/SettingsProvider/res/values/defaults.xml false false cell,bluetooth,wifi,nfc,wimax bluetooth,wifi,nfc
