1.通过代码控制wifi的开关

WifiManager wifiManager = PhoneManager.getWifiManager(context);

wifiManager.setWifiEnabled(true);//开启wifi

wifiManager.setWifiEnabled(false);//关闭wifi

2.通过代码控制手机流量的开关

输入参数

Context context;

boolean enabled;//true代表开，false代表关

需要权限:

<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />

/** * 开启关闭手机网络 * @param context * @param enabled */private void toggleMobileData(Context context, boolean enabled) {      ConnectivityManager connectivityManager =     (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);        //ConnectivityManager类      Class<?> connectivityManagerClass = null;    //ConnectivityManager类中的字段      Field connectivityManagerField = null;            //IConnectivityManager接口    Class<?> iConnectivityManagerClass = null;    //IConnectivityManager接口的对象    Object iConnectivityManagerObject = null;    //IConnectivityManager接口的对象的方法    Method setMobileDataEnabledMethod = null;    try {//取得ConnectivityManager类connectivityManagerClass = Class.forName(connectivityManager.getClass().getName());//取得ConnectivityManager类中的字段mServiceconnectivityManagerField = connectivityManagerClass.getDeclaredField("mService");//取消访问私有字段的合法性检查 //该方法来自java.lang.reflect.AccessibleObjectconnectivityManagerField.setAccessible(true);//实例化mService//该get()方法来自java.lang.reflect.Field//一定要注意该get()方法的参数://它是mService所属类的对象//完整例子请参见://http://blog.csdn.net/lfdfhl/article/details/13509839iConnectivityManagerObject = connectivityManagerField.get(connectivityManager);//得到mService所属接口的ClassiConnectivityManagerClass = Class.forName(iConnectivityManagerObject.getClass().getName());//取得IConnectivityManager接口中的setMobileDataEnabled(boolean)方法//该方法来自java.lang.Class.getDeclaredMethodsetMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);//取消访问私有方法的合法性检查 //该方法来自java.lang.reflect.AccessibleObjectsetMobileDataEnabledMethod.setAccessible(true);//调用setMobileDataEnabled方法setMobileDataEnabledMethod.invoke(iConnectivityManagerObject,enabled);} catch (ClassNotFoundException e) {       e.printStackTrace();  } catch (NoSuchFieldException e) {       e.printStackTrace();  } catch (SecurityException e) {       e.printStackTrace();  } catch (NoSuchMethodException e) {       e.printStackTrace();  } catch (IllegalArgumentException e) {       e.printStackTrace();  } catch (IllegalAccessException e) {       e.printStackTrace();  } catch (InvocationTargetException e) {       e.printStackTrace();  } }
