Please reproduce the issue you're having on snack.expo.io and then post it here. Thanks.

I wanna explain about this problem but before I explain it, some small problem here I put link of snack expo.
it is not updating value. these have values but it does not show except [Select a ....]
from react-native-picker-select.
Sorry I don't understand the issue you're having. Your nameArray is initialized with strings that match the option's labels, not values. Maybe that's the issue? If not, please try to explain in more detail.

I am not really understand this part
for(let i = 0; i < this.state.example.length; i++ {
<RNPickerSelect value={this.state.example[i].name} />
}
And, as far as I can guess that it seems you want to change the picker select items dynamically, if that is the case, you need to simply update the state (in your case as mentioned above, add items to example array, or remove items from example array) and the react-native render will/should do the rest for you.

closing due to inactivity

I have the same problem in that initially i have an array which is empty [] so no items show up in the dropdown . Then I make a network request and update the local state, which RN picker select is pulling from. I make sure that the state is update and state is re-rendered but the selection does not update with the new values of the updated state item.

@d7laungani can you recreate the issue on snack.expo.io or share a repo?
