Apparently I can’t find a focus event handler in NativeScript’s documentation or API reference of TextFields elements. Am I wrong?
Or, is there a way to introduce the onFocus event extending the existing TextField element?
(I am using typescript without Angular 2)
Any help appreciated, thank you,

p.s.: I posted this question on Stackoverflow too.
So apparently there is not a focus event, but I just use a tap event and do something while it gains focus as a default behaviour.
At least this is what I got on this answer on Stackoverflow.
It’s not the same actually, but for my specific needs it is enough.
[Android]
view.android.setOnFocusChangeListener(new
android.view.View.OnFocusChangeListener({
onFocusChange: function (v /*:android.view.View */, hasFocus /*: boolean*/) {
}
}));
[IOS]
you will need to create then attach a delegate to the textview
export class TextViewImpl extends NSObject implements UITextViewDelegate {
public static ObjCProtocols = [UITextViewDelegate];
textViewDidBeginEditing(textView: UITextView) {
}
textViewDidEndEditing?(textView: UITextView) {
};
}
view.ios.delegate = TextViewImp.new();
