Android Picker onValueChange is Firing on Initialization

See original GitHub issue

Description

I have a Picker whose list loads dynamically, based on what has previously been selected (mutually exclusive options). When I select a value from the list, I would like to move it to a different list and remove it from the Picker options. The issue is that, it selects the topmost value and fires the onValueChange for that value every time the list is re-rendered due to the setState. This causes every value to fire an event and empties the list.

Reproduction

RN Play Sample Here

Solution

onValueChange should not be fired when the Picker is initialized on Android. It should only trigger when an option is manually selected by the user.

Additional Information

  • React Native version: 0.41.2
