1前提条件 设备需要有个扫码器摄像头拍照识别也行APP调用扫码器读取WIFI连接分享码。 2增加权限 在AndroidManifest.xml中增加权限 uses-permission android:nameandroid.permission.ACCESS_WIFI_STATE /uses-permission android:nameandroid.permission.CHANGE_WIFI_STATE /uses-permission android:nameandroid.permission.ACCESS_NETWORK_STATE /
3参数检查 扫码成功后对内容进行一个基本的判断确认扫码数据中有P和T的参数
//WIFI连接
if (strResult.contains(P:) strResult.contains(T:)) {// 自动连接wifiConnectWifi(strResult);
}
4WIFI连接调用 private void ConnectWifi(String strResult){//取连接参数String passwordTemp strResult.substring(strResult.indexOf(P:));password passwordTemp.substring(2,passwordTemp.indexOf(;));String netWorkTypeTemp strResult.substring(strResult.indexOf(T:));netWorkType netWorkTypeTemp.substring(2,netWorkTypeTemp.indexOf(;));String netWorkNameTemp strResult.substring(strResult.indexOf(S:));netWorkName netWorkNameTemp.substring(2,netWorkNameTemp.indexOf(;));WifiAdmin wifiAdmin new WifiAdmin(MainActivity.this);if (!wifiAdmin.mWifiManager.isWifiEnabled()) {Toast.makeText(this, 开启wifi设置, Toast.LENGTH_LONG).show();wifiAdmin.openWifi();}int net_type 0x13;if (netWorkType.compareToIgnoreCase(wpa) 0) {net_type WifiAdmin.TYPE_WPA;// wpa} else if (netWorkType.compareToIgnoreCase(wep) 0) {net_type WifiAdmin.TYPE_WEP;// wep} else {net_type WifiAdmin.TYPE_NO_PASSWD;// 无加密}boolean bConnect wifiAdmin.addNetwork(netWorkName,password,net_type);//连接if(bConnect){Toast.makeText(this, 网络连接成功, Toast.LENGTH_LONG).show();}else{Toast.makeText(this, 网络连接失败, Toast.LENGTH_LONG).show();}}
