React Native. Best way for scroll to element inside ScrollView












0














I have scroll view with some component.



<ScrollView ref={ref => this.contentRef = ref}>
<SomeComponent ref={ref => this.targetRef = ref}
</ScrollView>


What is the best way for scroll to SomeComponent but limit to ScrollView height?



My try:



if (this.contentRef && this.targetRef) {
const UIManager = NativeModules.UIManager;
UIManager.measure(findNodeHandle(this.contentRef), (contentX, contentY, contentW, contentH) => {
UIManager.measure(findNodeHandle(this.targetRef), (activeStepX, activeStepY) => {
const h = Dimensions.get('window').height;
if (activeStepY > contentH / 2) {
this.contentRef.scrollTo({ x: 0, y: h, animated });
} else {
this.contentRef.scrollTo({ x: 0, y: contentH, animated });
};
});
});
};


But if target very close to screen bottom, I have empty space on bottom (sorry, I need to hide any information).

          Something like using onLayout method



          https://facebook.github.io/react-native/docs/view#onlayout



          e.g



          <ScrollView> 
          <YourComponent onLayout={this.onLayout()} />
          </ScrollView>


          onLayout(e) {
          return e.nativeEvent.layout.h // e.g would be the height of your scroll view
          }

          • I still receive empty area below after I scrolled

          • maybe try setting contentContainerStyle prop of ScrollView to {{ flex: 1 }} or {{ height: Dimensions.get("window").height }} or giving Your component some bottomPadding stylying, because ScrollView's prop overScrollMode is already set to 'auto' which allow a user to over-scroll the view only if the content is large enough to meaningfully scroll. hope these pointers could help helps
