做移动互联网站点网站如何快速收录

0，目标

        APP中实现扫WIFI分享码自动连接WIFI功能

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:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.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);
}

4，WIFI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();}}

5，WIFI连接类
