Scroll to current time in calendar component
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am creating my own calendar component using react-native. Hours in the day are displayed vertically, I would like to scroll to the current time, which is displayed by a horizontal red line.
I use Moment to find the current hour and minute using this method:
_findCurrentTime() {
const offset = 100;
const { format24h } = this.props;
const { width, styles } = this.props;
const timeNowHour = moment().hour();
const timeNowMin = moment().minutes();
const val = offset * (timeNowHour - this.props.start) + (offset * timeNowMin) / 60
return val;
}
I would like to use scrollView.scrollTo to scroll to the current time
<ScrollView
ref={scrollView => {
if (scrollView !== null) {
this.scrollView = scrollView;
scrollView.scrollTo({
x: 0,
y: scrollOffset,
animated: true
});
}
}}
contentContainerStyle={[
styles.contentStyle,
{ width: this.props.width }
]}
>
{this._renderLines()}
{this._renderEvents()}
{this._renderRedLine()}
</ScrollView>
How can I scroll to the current time, so the current time is always centered in the view? How would I be able to set scrollOffset?
