ViewPagerAndroid

Container that allows to flip left and right between child views. Each child view of the ViewPagerAndroid will be treated as a separate page and will be streched to fill the ViewPagerAndroid.

It is important all children are <View>s and not composite components. You can set style properties like padding or backgroundColor for each child.

Example:

render: function() {
  return (
    <ViewPagerAndroid
      style={styles.viewPager}
      initialPage={0}>
      <View style={styles.pageStyle}>
        <Text>First page</Text>
      </View>
      <View style={styles.pageStyle}>
        <Text>Second page</Text>
      </View>
    </ViewPagerAndroid>
  );
}

...

var styles = {
  ...
  pageStyle: {
    alignItems: 'center',
    padding: 20,
  }
}

Edit on GitHubProps #

initialPage number #

Index of initial page that should be selected. Use setPage method to update the page, and onPageSelected to monitor page changes

keyboardDismissMode enum('none', "on-drag") #

Determines whether the keyboard gets dismissed in response to a drag. - 'none' (the default), drags do not dismiss the keyboard. - 'on-drag', the keyboard is dismissed when a drag begins.

onPageScroll function #

Executed when transitioning between pages (ether because of animation for the requested page change or when user is swiping/dragging between pages) The event.nativeEvent object for this callback will carry following data: - position - index of first page from the left that is currently visible - offset - value from range [0,1) describing stage between page transitions. Value x means that (1 - x) fraction of the page at "position" index is visible, and x fraction of the next page is visible.

onPageSelected function #

This callback will be caleld once ViewPager finish navigating to selected page (when user swipes between pages). The event.nativeEvent object passed to this callback will have following fields: - position - index of page that has been selected
