It also create the events. So it means that i need to copy all that code back into my custom class.\r\n\r\nThere is a simple fix, and it would be a good practice for all classes, which to have class method like \r\n``` protected newNativeView(): android.widget.EditText``` (textfield example) which would be called inside the ```createNativeView```.\r\nThat way any subclass could return its own subclass of ```android.widget.EditText```\r\n\r\nDoing that for all widgets would make it dead easy to add native functionalities which require overriding native functions.","author":{"url":"https://github.com/farfromrefug","@type":"Person","name":"farfromrefug"},"datePublished":"2018-02-22T15:46:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/5456/NativeScript/issues/5456"}
