android 開發(fā)過程中如何判斷當(dāng)前是否是飛行模式和偵聽airplane mode change，本文將以此問題詳細(xì)介紹，需要了解的朋友可以參考下

Android中如何判斷系統(tǒng)當(dāng)前是否處于飛行模式中：

 
public static boolean IsAirModeOn(Context context) { 
return (Settings.System.getInt(context.getContentResolver(), 
Settings.System.AIRPLANE_MODE_ON, 0) == 1 ? true : false); 
} 

如何切換飛行模式

復(fù)制代碼代碼如下:

 
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); 
} 

如何注冊和取消自動飛行時(shí)間
注冊

復(fù)制代碼代碼如下:

 
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); 

如何控制切換飛行模式的硬件（cell,Bluetooth,wifi）

復(fù)制代碼代碼如下:

 
Settings.System.putString(context.getContentResolver(), 
Settings.System.AIRPLANE_MODE_RADIOS, air_mode_radios);air_mode_radios為一個(gè)這樣的字符串，看android源碼中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";
