Question

我以编程方式使用

与WiFi网络断开连接

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
 wifi.disconnect();
DisconnectWifi discon = new DisconnectWifi();
registerReceiver(discon, new IntentFilter(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION));


public class DisconnectWifi extends BroadcastReceiver  {

    @Override
    public void onReceive(Context c, Intent intent) {
     WifiManager wifi = (WifiManager) c.getSystemService(Context.WIFI_SERVICE);
        if(!intent.getParcelableExtra(WifiManager.EXTRA_NEW_STATE).toString().equals(SupplicantState.SCANNING)) 
         wifi.disconnect();
        }
    }

但我无法再次重新连接到同一网络。我尝试使用以下方法重新连接：

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.reconnect();

但无法连接。我现在如何重新连接到WiFi网络？

谢谢，

因此完整，简化的解决方案看起来像这样：

static mapping = {
        mstAttributeList {
            column name: 'SITE'
            column name: 'MACHINE_FK', sqlType: 'nvarchar2'             
        }           
        mstAttributeList joinTable: [name: 'MST_MACHINE_ATTRIBUTE', key: ['MACHINE_FK', 'SITE']]
}

static hasMany = [ mstAttributeList : com.gknsintermetals.mda.master.MstAttribute ]

希望它能帮助你!!
