Android WiFi热点开发的示例代码
上次写了Android连接匿名WiFi的内容。WiFI开发对于应用层开发是比较小众的知识点,不过既然用到了就在此记录下。
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
staticWifiConfigurationcreateWifiConfig(StringSSID,@WifiSecurityTypeintwifiCipherType,Stringpassword,booleanhiddenSSID){ WifiConfigurationwifiConfiguration=newWifiConfiguration(); 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){ caseWifiSecurityType.SECURITY_NONE: wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); break; caseWifiSecurityType.SECURITY_WEP: wifiConfiguration.allowedKeyManagement.set(KeyMgmt.NONE); wifiConfiguration.allowedAuthAlgorithms.set(AuthAlgorithm.OPEN); wifiConfiguration.allowedAuthAlgorithms.set(AuthAlgorithm.SHARED); if(!TextUtils.isEmpty(password)){ intlength=password.length(); //WEP-40,WEP-104,and256-bitWEP(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; caseWifiSecurityType.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; caseWifiSecurityType.SECURITY_WPA_EAP: wifiConfiguration.allowedKeyManagement.set(KeyMgmt.WPA_EAP); wifiConfiguration.allowedKeyManagement.set(KeyMgmt.IEEE8021X); wifiConfiguration.enterpriseConfig=newWifiEnterpriseConfig(); inteapMethod=0; intphase2Method=0; wifiConfiguration.enterpriseConfig.setEapMethod(eapMethod); wifiConfiguration.enterpriseConfig.setPhase2Method(phase2Method); if(!TextUtils.isEmpty(password)){ wifiConfiguration.enterpriseConfig.setPassword(password); } break; default: break; } returnwifiConfiguration; }
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{ Methodmethod=mWifManager.getClass().getMethod( "setWifiApEnabled",WifiConfiguration.class,Boolean.TYPE); booleanenable=(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(Exceptione){ 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:
publicvoidcloseWifiAp(){ try{ Methodmethod=mWifiManager.getClass().getMethod("setWifiApEnabled",WifiConfiguration.class,boolean.class); method.invoke(mWifiManager,null,false); }catch(Exceptione){ 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:
publicstaticfinalStringWIFI_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:
IntentFilterfilter=newIntentFilter(); filter.addAction("android.net.wifi.WIFI_AP_STATE_CHANGED");
然后在广播中获取state:
intstate=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:
publicintgetWifiApState()
判断WiFi热点是否打开:
publicbooleanisWifiApEnabled()
获取当前wifi热点的WifiConfiguration:
publicWifiConfigurationgetWifiApConfiguration()
