How can i check the state of toggle button for wifi?

Question

In my application i have a toggle button that needs to activate or disable the wifi.

    public void getRisparmio(View view) {
    // is the toggle on?
    boolean on = ((ToggleButton) view).isChecked();

    WifiManager wifiManager;
    if (on) {
      wifiManager(WifiManager) this.getSystemService(Context.WIFI_SERVICE);
      wifiManager.setWifiEnabled(true);
    } else {
      wifiManager(WifiManager) this.getSystemService(Context.WIFI_SERVICE);
      wifiManager.setWifiEnabled(false);
    }
    }

Now the problem is: if the wifi is already activated and I launch the app, the toggle button should be pressed/activated. Actually doesn't go and the toggle always resume its state on off. I think i can check the state onResume() but i don't know how and i don't know if i have to add something in the onCreate() method too.

How can i do to check the state? Thanks

You will have to set the toggle button in onCreate() and onResume() using the toggle button's method as such:

toggleButton.setChecked(wifiManager.isWifiEnabled());

E.g.

@Override 
protected void onResume() 
{ 
    super.onResume();
    WifiManager wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
    ToggleButton toggleButton = (ToggleButton) findViewById(R.id.toggleButton1);
    toggleButton.setChecked(wifiManager.isWifiEnabled()); 
}
