Android O WifiManager.enableNetwork() cannot work

Fist of all, I manually set up two wifi with my phone, then I use WifiManager.enableNetwork() I can successfully switch wifi, but after a few seconds, wifi switches back to the previous wifi, what is the reason? please tell me.

Device: ASUS ZenFone 5 (Android 8.0.0)

Code:

void connectWiFi(String networkSSID) {
    int networkId = getNetworkId(networkSSID);
    wifiManager.disconnect();
    wifiManager.enableNetwork(networkId, true);
    wifiManager.reconnect();
}

int getNetworkId(String ssid) {
    List<WifiConfiguration> configurations = wifiManager.getConfiguredNetworks();
    for (WifiConfiguration config : configurations) {
        if (config.SSID != null && config.SSID.equals("\"" + ssid + "\"")) {
            return config.networkId;
        }
    }
    return -1;
}

I found the answer.

First, use the broadcast to listen to WiFi disconnect, then use wifiManager.disconnect(), wait for the broadcast to disconnect, and then use wifiManager.enableNetwork(networkId, true).
