创建热点
1、根据加密类型、密码、是否隐藏等参数来创建热点
static WifiConfiguration createWifiConfig(String SSID, @WifiSecurityType int wifiCipherType, String password, boolean hiddenSSID) {
WifiConfiguration wifiConfiguration = new WifiConfiguration();
wifiConfiguration.SSID = convertToQuotedString(SSID);
wifiConfiguration.hiddenSSID=hiddenSSID;//是否隐藏热点true=隐藏,如果隐藏需要其他设备手动添加网络
switch (wifiCipherType) {
case WifiSecurityType.SECURITY_NONE:
wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
break;
case WifiSecurityType.SECURITY_WEP:
wifiConfiguration.allowedKeyManagement.set(KeyMgmt.NONE);
wifiConfiguration.allowedAuthAlgorithms.set(AuthAlgorithm.OPEN);
wifiConfiguration.allowedAuthAlgorithms.set(AuthAlgorithm.SHARED);
if (!TextUtils.isEmpty(password)) {
int length = password.length();
// WEP-40, WEP-104, and 256-bit WEP (WEP-232?)
if ((length == 10 || length == 26 || length == 58)
&& password.matches("[0-9A-Fa-f]*")) {
wifiConfiguration.wepKeys[0] = password;
} else {
wifiConfiguration.wepKeys[0] = '"' + password + '"';
}
}
break;
case WifiSecurityType.SECURITY_WPA_PSK:
wifiConfiguration.allowedKeyManagement.set(KeyMgmt.WPA_PSK);
if (!TextUtils.isEmpty(password)) {
if (password.matches("[0-9A-Fa-f]{64}")) {
wifiConfiguration.preSharedKey = password;
} else {
wifiConfiguration.preSharedKey = '"' + password + '"';
}
}
break;
case WifiSecurityType.SECURITY_WPA_EAP:
wifiConfiguration.allowedKeyManagement.set(KeyMgmt.WPA_EAP);
wifiConfiguration.allowedKeyManagement.set(KeyMgmt.IEEE8021X);
wifiConfiguration.enterpriseConfig = new WifiEnterpriseConfig();
int eapMethod = 0;
int phase2Method = 0;
wifiConfiguration.enterpriseConfig.setEapMethod(eapMethod);
wifiConfiguration.enterpriseConfig.setPhase2Method(phase2Method);
if (!TextUtils.isEmpty(password)) {
wifiConfiguration.enterpriseConfig.setPassword(password);
}
break;
default:
break;
}
return wifiConfiguration;
}然后调用WifiManager的setWifiApEnabled方法来设置wifiConfiguration，因为是隐藏的，需要通过反射：
try {
Method method = mWifManager.getClass().getMethod(
"setWifiApEnabled", WifiConfiguration.class, Boolean.TYPE);
boolean enable = (Boolean) method.invoke(mWifManager, config, true);
if (enable) {
Log.d("WiFi", "热点已开启");
} else {
Log.d("WiFi", "创建热点失败");
}
} catch (Exception e) {
e.printStackTrace();
}关闭热点
关闭热点比较简单，也是用上面的方法，第二个参数传false就行了：
public void closeWifiAp() {
try {
Method method = mWifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
method.invoke(mWifiManager, null, false);
} catch (Exception e) {
e.printStackTrace();
}
}监听热点状态
热点的状态可以通过广播的方式来监听：
public static final String WIFI_AP_STATE_CHANGED_ACTION = "android.net.wifi.WIFI_AP_STATE_CHANGED";
不过这个变量是隐藏的，只能直接通过值来注册广播：
IntentFilter filter = new IntentFilter();
filter.addAction("android.net.wifi.WIFI_AP_STATE_CHANGED");然后在广播中获取state：
int state = intent.getIntExtra("wifi_state", 0);wifi热点有如下几种状态：
#WIFI_AP_STATE_DISABLED #WIFI_AP_STATE_DISABLING #WIFI_AP_STATE_ENABLED #WIFI_AP_STATE_ENABLING #WIFI_AP_STATE_FAILED
其他API：
获取WiFI热点当前状态，返回值就是上面五种状态：
public int getWifiApState()
判断WiFi热点是否打开：
public boolean isWifiApEnabled()
获取当前wifi热点的WifiConfiguration：
public WifiConfiguration getWifiApConfiguration()
