Custom NavBar with custom TabBar #885
Comments
What does your NavBar code look like? |
Original post updated with NavBar |
Hm, even if your navbars are separate instances, they should have the correct state. Make sure you're reading the navigationState correctly, maybe compare to the original one and see how they are reading the new state. https://github.com/aksonov/react-native-router-flux/blob/master/src/NavBar.js |
Ok, so I went ahead and tried to use the provided prop interface supplied by RNRF and am getting the same result. It doesn't seem to matter whether I remove To recap my question:
UPDATE: I'm guessing this line from the docs is the answer to this question though sort of seems odd. The second question is the one that is holding me up.
Here is the updated navigation
|
I would believe that you wouldn't want a back button on a child tab scene. Navigation at that point should be between tabs. If you navigate to a scene from a tab, you will then want to go back - but only as far as the tabs. This is a "sane" default as most tab based navigators are root scenes - but obviously you have a use case for otherwise. I'll have to take a deeper dive or get @joenoon in here to find a next step. |
@lifehackett in my app I use a custom navBar and I set it in the jsx on every immediate child of a And since these are the tab root scenes (index: 0), it makes sense to me that no back button is appearing... but you are using a custom NavBar that doesn't handle |
Thank you for the responses. Prior to upgrading RN and then RNRF my custom nav bar worked as I've described I would like it to work, so either it seems like a bug that it changed or there was a conscious decision to "re-root" navigation when tabs are introduced. @joenoon the IMO it would make sense that tabs occupy a place in the state stack similar to any other scene. So in my case if you navigated |
@lifehackett I missed that navBar variable but now that you point it out I understand. The state tree from your code as I understand it would be something like this:
You might want to try console.log'ing the state to make sure or see what is changing. This is just a best guess but hopefully will get you started. |
@joenoon Sorry about that sort of being buried. I was trying out the approach to see if it would work and didn't put enough effort into readability. Admittedly, I don't have a great grasp on the RN navigation stuff yet so really appreciate your time and effort; the diagram is most helpful. I am heading out of town shortly, but will do this exercise Tuesday and if everything seems to check out will close this thread then it if you don't mind waiting until then. |
Has there been any solution to this? |

Version
Tell us which versions you are using:
Expected behaviour
Displays my custom navBar
Actual behaviour
Displays the default navBar
Steps to reproduce
I am going through the process of upgrading RN from 22-28. First, thanks for all your hard work around their moving target of a Navigation API. Using your TabView and TabBar as a template I have gotten the tab bar working again, but my custom NavBar has been replaced with the default one. I have tried applying
hideNavBar={ true }
at the tab bar level (nothing happens) and at the individual tab level (tab bar is hidden). I have also tried applying the navBar again at these same levels and the correct one gets displayed, but it doesn't have the correct navigation state presumably because it is a separate instance.UPDATE: NavBar implementation
