Android无线管理

涉及到无线、Wifi等操作时，模拟器就不行了，一定找一台真机进行测试

Android无线(Wifi)管理主要是WifiManager类，位于android.net.wifi包下面

最常用的类：WifiManager

获取WifiManager实例：Context.getSystemService(Context.WIFI_SERVICE)

import java.util.List;import android.content.Context;import android.net.wifi.ScanResult;import android.net.wifi.WifiConfiguration;import android.net.wifi.WifiInfo;import android.net.wifi.WifiManager;import android.net.wifi.WifiManager.WifiLock;public class WifiManagerTools{//定义WifiManager对象private WifiManager mWifiManager;//定义WifiInfo对象private WifiInfo mWifiInfo;//扫描出的网络连接列表private List<ScanResult> mWifiList;//网络连接列表private List<WifiConfiguration> mWifiConfiguration;//定义一个WifiLockWifiLock mWifiLock;//构造器public  WifiManagerTools(Context context){//取得WifiManager对象mWifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);//取得WifiInfo对象mWifiInfo = mWifiManager.getConnectionInfo();}//打开WIFIpublic void OpenWifi(){if (!mWifiManager.isWifiEnabled()){mWifiManager.setWifiEnabled(true);}}//关闭WIFIpublic void CloseWifi(){if (!mWifiManager.isWifiEnabled()){mWifiManager.setWifiEnabled(false);}}//锁定WifiLockpublic void AcquireWifiLock(){mWifiLock.acquire();}//解锁WifiLockpublic void ReleaseWifiLock(){//判断时候锁定if (mWifiLock.isHeld()){mWifiLock.acquire();}}//创建一个WifiLockpublic void CreatWifiLock(){mWifiLock = mWifiManager.createWifiLock("Test");}//得到配置好的网络public List<WifiConfiguration> GetConfiguration(){return mWifiConfiguration;}//指定配置好的网络进行连接public void ConnectConfiguration(int index){//索引大于配置好的网络索引返回if(index > mWifiConfiguration.size()){return;}//连接配置好的指定ID的网络mWifiManager.enableNetwork(mWifiConfiguration.get(index).networkId, true);}public void StartScan(){mWifiManager.startScan();//得到扫描结果mWifiList = mWifiManager.getScanResults();//得到配置好的网络连接mWifiConfiguration = mWifiManager.getConfiguredNetworks();}//得到网络列表public List<ScanResult> GetWifiList(){return mWifiList;}//查看扫描结果public StringBuilder LookUpScan(){StringBuilder stringBuilder = new StringBuilder();for (int i = 0; i < mWifiList.size(); i++){stringBuilder.append("Index_"+new Integer(i + 1).toString() + ":");//将ScanResult信息转换成一个字符串包//其中把包括：BSSID、SSID、capabilities、frequency、levelstringBuilder.append((mWifiList.get(i)).toString());stringBuilder.append("/n");}return stringBuilder;}//得到MAC地址public String GetMacAddress(){return (mWifiInfo == null) ?
