react-native - 如何在Native Base 组件中 "Scroll To Top"？

Question

我正在使用Expo并在其上实现Native Base，每当“MainTabNavigator”图标<Ionicons/>都在尝试执行“滚动到顶部”

应该以<Content>还是<Ionicons/>(在MainTabNavigator中)实现句柄？

Answer 1

试试这个

 <Container>
    <Content ref={c => (this.component = c)}>
      <Text style={styles.text}>test</Text>
      <Text style={styles.text}>test</Text>
      <Text style={styles.text}>test</Text>
      ...
      ...
      ...
      ...

      <Button onPress={() => this.component._root.scrollToPosition(0, 0)}>
        <Text>Back to top</Text>
      </Button>
    </Content>
  </Container>
