Android監聽Gps設置變化方法二

上一篇提到用內容觀察者通過來監聽數據庫變化獲取GPS狀態，其實在GPS狀態或模式改變時，

會發出相應的廣播LocationManager.MODE_CHANGED_ACTION，LocationManager.PROVIDERS_CHANGED_ACTION

這里貼出關鍵代碼：

////注冊廣播

IntentFilter filter = new IntentFilter();
filter.addAction(LocationManager.MODE_CHANGED_ACTION);
filter.addAction(LocationManager.PROVIDERS_CHANGED_ACTION);
mServiceBroadcast = new ServiceBroadcast();
registerReceiver(mServiceBroadcast,filter);

///接收廣播并進行相應處理

String action =  intent.getAction();

if(action.equals(LocationManager.MODE_CHANGED_ACTION) || action.equals(LocationManager.PROVIDERS_CHANGED_ACTION)){

LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
boolean gpsEnabled = manager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if(gpsEnabled){
if(!Pedometer.isServiceStart(context,"")){
bindService(new Intent(PedometerService.this,GpsService.class),gpsconnection,Context.BIND_AUTO_CREATE);
}
}
}
