When the React Native app is clicked for the first time, the animation fails to activate

Why is my animation effect not working the first time I click it? Also, can anyone provide an example of using TypeScript with ref binding in React Native for animations?

const Test = () => {
  const messRef: any = React.useRef(new Animated.Value(0)).current;
  const [show, setShow] = React.useState<boolean>(false);

  return (
    <View>
      <Animated.Text
        onPress={() => {
          Animated.timing(messRef, {
            toValue: show ? 200 : 0,
            duration: 1000,
            useNativeDriver: false,
          }).start();
          setShow(!show);
        }}
        style={{
          color: messRef.interpolate({
            inputRange: [0, 100],
            outputRange: ["orange", "blue"],
          }),
        }}
      >
        Everything you do in life stems from either fear or love
      </Animated.Text>
    </View>
  );
};

Answer №1

The problem lies in

toValue: show ? 200 : 0,

Initially, the value of show is false and when you click for the first time, the value of toValue will be set back to 0. Change it to

toValue: !show ? 200 : 0,
