- android的热点功能不可见,用了反射的技术搞定之外。
- Eclipse设置语言为utf-8才能查看中文注释

xml布局简单不上了,
效果自己试试看打印就知道了
//分为三种情况:1没有密码2用wep加密3用wpa加密
改动主要集中在CreateWifiInfo这个方法中,并且添加了一个私有方法:
(1)将与方法的第三个参数有关的变量都改成int型,或者使用原作者的枚举型(存在bug需要改正),但枚举会在后续的开发中遇到些困难;
(2)在if(type == 3)中注释掉“config.allowedProtocols.set(WifiConfiguration.Protocol.WPA);”,并添加“
config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);“这两句,否则当wifi热点需要输入密码时,无法加入网络。
(3)在代码末尾添加了方法IsExsits,原因在于如果按照网上介绍的方法成功加入指定的wifi后,都会在终端的wifi列表中新添加一个以该指定ssid的网络,所以每运行一次程序,列表中就会多一个相同名字的ssid。而该方法就是检查wifi列表中是否有以输入参数为名的wifi热点,如果存在,则在CreateWifiInfo方法开始配置wifi网络之前将其移除,以避免ssid的重复:
WifiConfiguration tempConfig = this.IsExsits(SSID);
if(tempConfig != null) {
mWifiManager.removeNetwork(tempConfig.networkId);
}
以上便是wifi工具类的建立,之后就可以在其他部分实例化这个类,调用其中的方法完成加入指定ssid的wifi热点,还是先上代码吧,建立一个名为Test_wifiActivity.java的文件(同上,没有包含包声明和import语句):
[java]
public class Test_wifiActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WifiAdmin wifiAdmin = new WifiAdmin(this);
wifiAdmin.openWifi();
wifiAdmin.addNetwork(wifiAdmin.CreateWifiInfo("XXX", "XXX", 3));
}
}
很简单,如果是接入wifi,大体上只涉及到openWifi(打开wifi)、CreateWifiInfo(配置wifi网络信息)和addNetwork(添加配置好的网络并连接),对CreateWifiInfo进行简单的说明:第一参数是SSID的名称;第二个参数是指定SSID网络的密码,当不需要密码是置空(”“);第三个参数是热点类型:1-无密码 / 2-WEP密码验证(未测试)/ 3-WAP或WAP2 PSK密码验证。
连接不加密热点总是失败 addNetwork总是返回-1的解决办法:
if(Type == WifiCipherType.WIFICIPHER_NOPASS)
{
config.hiddenSSID = true;
// config.wepKeys[0] = "";
config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
// config.wepTxKeyIndex = 0;
}
把与wep有关的都注释掉就行了
