QUESTION
How to re-render the data? I update the data but it is not output.
Sample code on the line 34.
...ANSWER
Answered 2018-May-10 at 14:14You are not properly updating your state variable. You are mutating the state by inserting a new element into the data
array. This change is not triggering any state update, hence render
method is not called. As per React
document, we should not mute the state directly
Never mutate this.state directly, as calling setState() afterwards may replace the mutation you made. Treat this.state as if it were immutable.
Change the state update as (using ES6)
QUESTION
I have some UI that looks like this:
These list items can be: (1) added, (2) deleted, (3) reordered.
The reordering is not drag and drop, but happens when clicking the check/empty circle icons - the checked items always stay at the top of the list.
There are many examples of animating adding/removing items from lists in React Native (here's one such example).
But how can I animate the ordering of a list? Specifically in my case, it would be two list items swapping position.
I have seen react-native-sortable-list and a few other open source projects, but I think this is probably overkill as I do not need drag and drop. Also, I am already hooking into some FlatList events like onLayout
, onContentSizeChange
, and onScroll
, so I would prefer a solution that allows me to animate the children of a FlatList directly.

prop. Whether you are using component-level state (i.e. this.state
) or redux to manage your state, you can reorder the array of elements and it should rerender in that order. For example, one implementation may be:
