Android中如何判断系统当前是否处于飞行模式中：
复制代码 代码如下:
public static boolean IsAirModeOn(Context context) {
return (Settings.System.getInt(context.getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, 0) == 1 ? true : false);
}
如何切换飞行模式
复制代码 代码如下:
public static void setAirplaneMode(Context context, boolean enabling) {
Settings.System.putInt(context.getContentResolver(),
Settings.System.AIRPLANE_MODE_ON, enabling ? 1 : 0);
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", enabling);
context.sendBroadcast(intent);
}
如何注册和取消自动飞行时间
注册
复制代码 代码如下:
AlarmManager am = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(AIR_ALERT_ACTION);
Parcel out = Parcel.obtain();
air.writeToParcel(out, 0);
out.setDataPosition(0);
intent.putExtra(AIR_RAW_DATA, out.marshall());
PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, atTimeInMillis, sender);取消
AlarmManager am = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
endingIntent sender = PendingIntent.getBroadcast(context, 0,
new Intent(action), PendingIntent.FLAG_CANCEL_CURRENT);
am.cancel(sender);
如何控制切换飞行模式的硬件（cell,Bluetooth,wifi）
复制代码 代码如下:
Settings.System.putString(context.getContentResolver(),
Settings.System.AIRPLANE_MODE_RADIOS, air_mode_radios);air_mode_radios为一个这样的字符串，看android源码中android/provider/Settings.java
/***
* Whether Airplane Mode is on.
*/
public static final String AIRPLANE_MODE_ON = "airplane_mode_on";
/***
* 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";
/***
* Constant for use in AIRPLANE_MODE_RADIOS to specify Cellular radio.
*/
public static final String RADIO_CELL = "cell";
/***
* 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";
/***
* 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";
如果air_mode_radios=“cell,bluetooth,wifi”,这就便是切换飞行模式是切换字符串中的这cell,bluetooth,wifi硬件，我们可以通过设置该字符串的值，来控制这三个硬件是否在切换飞行模式是进行切换状态。
