React Native相当于mousedown

Question

If I'm making a website, I can use a mousedown event to trigger something when the mouse button is pressed (and not yet released).

In React Native, I've got a TouchableHighlight and can register an onPress callback, but this only triggers when I release my finger from the button.

Is there a way to trigger as soon as a finger touches a button, rather than only when the finger is released?

Solved shortly afterwards! The onResponderStart prop is what I needed. This isn't actually documented in the gesture responder system docs , but it seems to work for me!

<View onStartShouldSetResponder={() => true}
      onResponderStart={calledWhenTheTouchStarts}>

    <Text>Press Me!</Text>

</View>
