GPS，蓝牙，数据漫游的开启关闭，会修改系统的数据表，通过监听数据表中数据变化来判断打开，关闭操作。

// GPS 及 网络定位        application.getContentResolver().registerContentObserver(                Settings.Secure.getUriFor(Settings.Secure.LOCATION_PROVIDERS_ALLOWED), false,                settingsObserver);        // 启用蓝牙        application.getContentResolver().registerContentObserver(                Settings.Secure.getUriFor(Settings.Secure.BLUETOOTH_ON), false, settingsObserver);        // 数据漫游        application.getContentResolver().registerContentObserver(                Settings.Secure.getUriFor(Settings.Secure.DATA_ROAMING), false, settingsObserver);private SettingsObserver settingsObserver = new SettingsObserver(new Handler(            application.getMainLooper())); public class SettingsObserver extends ContentObserver {        public SettingsObserver(Handler handler) {            super(handler);        }        @Override        public void onChange(boolean paramBoolean) {            super.onChange(paramBoolean);        }    }       //true GPS开启状态；false 关闭状态boolean bool1 = Settings.Secure.isLocationProviderEnabled(application.getContentResolver(), LocationManager.GPS_PROVIDER); /**     * 评估和设置蓝牙     */    public boolean evaluateAndSetBluetooth() {    BluetoothAdapter localBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();//需要等待            Thread.sleep(500);//打开蓝牙localBluetoothAdapter.enable();//关闭蓝牙//localBluetoothAdapter.disable();   } /** 是否数据漫游 */    public boolean isDataRoamingEnabled() {        try {            if (Settings.Secure.getInt(context.getContentResolver(), "data_roaming") == 0) {                return false;            } else {                return true;            }        } catch (SettingNotFoundException e) {            e.printStackTrace();            return false;        }    }
