I know that TextInput's native text has an onsubmit callback function, but how can I make this submit button?

Question

I would like to know how to draw this button, and if so, is it automatically bound to the text in the input field?

Answer 1

Basically onSumbitEditing will display a onSumbitEditing event when you press the go button on the Android keyboard, as shown below:

  <TextInput style={[styles.zipCode, styles.mainText]} returnKeyType='My Custom button' onSubmitEditing={(event) => this.updateText( event.nativeEvent.text )}/> 

in the code snippet above: I have the name of the action - this is “My custom button”, which will appera on the soft keyboard in Android and when you click on the updateText event is triggered, here's what the value of onSubmitEditing is

Note: if the physical keyboard is enabled in the android emulator, therefore, onSubmitEditing will not tiger any event, since you will also not need to press a virtual key called the name "My custom button"

Answer 2

The onSubmit callback is called when you press the done / return / join button on the keyboard that appears

Answer 3

You might have something like this:

 onSubmitEdit = () => { // whatever you want to do on submit } render() { return( <View> <TextInput style={styles.input} textAlign="center" onSubmitEditing={this.submitEdit} /> <TouchableHighlight onPress={this.onSubmitEdit}> <Text>Press this button to submit editing</Text> </TouchableHighlight> </View> ); }
