Android Question Form not complete

[AHilberink]

Hi,

Is it possible to get a waved red line or something, when a user forgot to fill in the edittext field of my form?

On programming and I do something wrong, the wrong line will have a waved red underline.

I want to do something for my app.

Best regards,
André

You can handle the TextChanged event and when the text is not valid do something. You can for example add a small panel under the EditText and change its background to red.
