我试图在React Native for Android中使用水平ScrollView,其中起始位置位于滚动图像的中间而不是(0,0).

该scrollTo方法似乎在内部正确调用,componentDidMount但在应用程序中没有任何移动,它仍然显示为从左侧开始滚动.

由于这是Android,我没有访问contentOffset道具或我会直接设置,根据文档.这是代码:

'use strict';

  constructor(props, context) {
    super(props, context);

  componentDidMount() {
    this.myScroll.scrollTo(100);
    console.log("called DidMount");
  }

  render() {
    return (
      <View style={{flex: 1}}>
        <ScrollView ref={(ref) => this.myScroll = ref}
          contentContainerStyle={styles.container}
          horizontal={true}
          pagingEnabled={true}
          showsHorizontalScrollIndicator={false}
          bounces={true}
          onMomentumScrollEnd={this.onAnimationEnd}
        >
          {this.props.children}
        </ScrollView>
      </View>
    );
  }

  onAnimationEnd(e) { …
