RefreshControl only appearing on top of first child in a horizontal ScrollView (iOS)


I have a use case where I want to list horizontally cards. I implemented it with a horizontal ScrollView.

Then, for each card I would like to implemented the pull-to-refresh pattern so that the data displayed in the card are updated. I used therefore the RefreshControl component as an attribute of the ScrollView.

The issue is that on iOS, when I switch to another card than the 1st, I cannot see the RefreshControl component (see gif below).

horizontal scroll with refresh control iOS

Code

<ScrollView
  contentContainerStyle={styles.container}
  horizontal
  pagingEnabled
  showsHorizontalScrollIndicator={false}
  directionalLockEnabled
  contentInset={{top: 1}}
  refreshControl={
    <RefreshControl
      refreshing={this.state.isRefreshing}
      onRefresh={this._onRefresh.bind(this)}
    />
  }
>
  <Text style={styles.card}>First child</Text>
  <Text style={styles.card}>Second child</Text>
</ScrollView>

Edit

It looks related to this part of the code : Libraries/Components/ScrollView/ScrollView.js#L523-L529


Solution

  • As far as I know, this is expected behavior of refreshControl- there is only supposed to be one.

    Would this work for your app?

    <ScrollView
      contentContainerStyle={styles.container}
      horizontal
      pagingEnabled
      showsHorizontalScrollIndicator={false}
      directionalLockEnabled
      contentInset={{top: 1}}
    >
      <ScrollView
        refreshControl={
          <RefreshControl
            refreshing={this.state.isRefreshing}
            onRefresh={this._onRefresh.bind(this)}
          />
        }><Text style={styles.card}>First child</Text></ScrollView>
      <ScrollView
        refreshControl={
          <RefreshControl
            refreshing={this.state.isRefreshing}
            onRefresh={this._onRefresh.bind(this)}
          />
        }><Text style={styles.card}>Second child</Text></ScrollView>
    </ScrollView>
