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

This piece of code worked for me. What I was missing was I was not passing 'this' in button action:

 onPress={this._handlePress.bind(this)}>
--------------

  _handlePress(event) {
console.log('Pressed!');

 var username = this.state.username;
 var password = this.state.password;

 console.log(username);
 console.log(password);
}

  render() {
    return (
      

       {
          this.setState({username:text});
        }}
      onSubmitEditing={(event) => {
     this.refs.psw.focus();

      }}
      />

       {
          this.setState({password:text});
        }}
      />

      
        Login
      

      
    );``
  }
}
