此代码用于连接WiFi.在Android Lollipop上运行正常，但我想以编程方式为棉花糖设置配置.我已授予所有运行时权限和危险权限，但仍无济于事，无法删除保存的WiFi密码.如果有人为棉花糖做过这将是有帮助的.

This code is for connecting to WiFi. It's working fine on Android Lollipop but I want to set up configuration programmatically for Marshmallow. I've given all the run time permissions and dangerous permission but still no help and unable to remove saved WiFi passwords. If anyone has done this for Marshmallow it would be helpful.

推荐答案

好吧...我们对连接到棉花糖中wifi网络的代码进行了少量更改.我认为以下代码将为您服务...

Well...We have small changes in the code for connect to the wifi network in Marshmallow.. I think the following code will works for you...

public void connectToWifi(){
    try{
        WifiManager wifiManager = (WifiManager) super.getSystemService(android.content.Context.WIFI_SERVICE);
        WifiConfiguration wc = new WifiConfiguration();
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        wc.SSID = "\"NETWORK_NAME\"";
        wc.preSharedKey = "\"PASSWORD\"";
        wc.status = WifiConfiguration.Status.ENABLED;
        wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
        wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        int netId = wifiManager.addNetwork(wc);
        if (netId == -1) {
            netId = getExistingNetworkId(wc.SSID);
        }
        wifiManager.disconnect();
        wifiManager.enableNetwork(netId, true);
        wifiManager.reconnect();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
private int getExistingNetworkId(String SSID) {
    WifiManager wifiManager = (WifiManager) super.getSystemService(Context.WIFI_SERVICE);
    List<WifiConfiguration> configuredNetworks = wifiManager.getConfiguredNetworks();
    if (configuredNetworks != null) {
        for (WifiConfiguration existingConfig : configuredNetworks) {
            if (existingConfig.SSID.equals(SSID)) {
                return existingConfig.networkId;
            }
        }
    }
    return -1;
}

并在清单文件中添加权限

And add Permissions in the Manifest file

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
