System Keyboard support?

[kamend]

Not exactly an issue, but did you manage to get UIToolkit Input Fields working with the System Keyboard?

Hi! Yes, they are working mostly out of the box (at least for Android). I have also been successful with a Meta Quest 2 and a Hololens. Depending on the device and the scenario, you can manipulate the keyboard's behaviour. You can do this with Unity's TouchScreenKeyboard.

Here's an example:

private TextField _username;
private TouchScreenKeyboard _keyboard;

_username = _container.GetXRUIVisualElement<TextField>("username");

// Open keyboard when getting focus
_username.RegisterCallback<FocusInEvent>((e) =>
{
    _keyboard = TouchScreenKeyboard.Open("");
    _keyboard.text = String.Empty;
    _keyboard.active = true;
});

// Close keyboard when losing text field focus 
_username.RegisterCallback<FocusOutEvent>((_) =>
{
    _keyboard.active = false;
});

// Update text field with keyboard value
_username.RegisterValueChangedCallback(evt =>
{
    if (_keyboard != null)
        _username.value = _keyboard.text;
});

Hope this helps :)
