react native get TextInput value

Question

I am stuck with a very simple problem. I have login form with username, password and button. In my button handler, I try to get the textinput value. But always get undefined

Answer 1

If you set the text state, why not use that directly?

_handlePress(event) {
  var username=this.state.text;

Of course the variable naming could be more descriptive than 'text' but your call.
