[Bug] [Android] Not all pages added to TabbedPage show up in "more" #14219

Open tentom opened 3 years ago

tentom commented 3 years ago

Description

When adding multiple pages to a TabbedPage the "more" list shows up after five pages are added (as expected). Adding even more pages works fine until the fills the entire screen. Then adding one more page makes it unreachable with out using swipe navigation from the page before it.

Works as expected on iOS.

My first issue for the xamarin.Forms repo, please let me know if there is something unclear or if more info is needed.

Steps to Reproduce

  1. Add multiple pages to a TabbedPage
  2. Try to reach the last page.

Expected Behavior

The "more" list starts to scroll if the entire screen is full.

Actual Behavior

Last pages in the "more" menu is off screen and unreachable.

Hi, @tentom - thanks for submitting this issue. Have you been able to repro on any other Android devices? I unfortunately don't have a Sony Xperia to experiment with, and wasn't able to repro on my Pixel 4A :/

Hi, sorry for not responding earlier, no sadly I do not have a second Android device around.

It seem like you have a screen that are taller than mine, what happens if we add more menu items so it will fill the screen?

I have updated the source repo with 30 entries instead of the 16 that was when you tried it.

I also added a screen recording:

@rachelkang Have you tried the Latest project zip where there are 30 entries, as in the first example all 8 entries did fit on the screen on the android device you used and then the issue is not apparent.
