Description Chris Riesgo 2014-09-24 09:54:25 UTC
- Xamarin.Forms Shared Libraries project
- Android Xamarin.Forms package
- Android project using X.F Shared Libraries
- Testing on Genymotion Nexus 5 API 19 (but elsewhere also)

App Structure:
- MainActivity content is set to a new NavigationPage(page)
- NavigationPage.SetHasNavigationBar(page, false) is set
- OnResume of MainActivity, a modal page is pushed to the Navigation Stack
- An Entry control on the modal page is displayed
- Upon tapping into the Entry control, the Placeholder text shifts upward
- Once you begin entering text, the text shifts back to its expected location
- In other tests, causing an Alert dialog to appear causes the text to shift back upward

The main issue seems to be that the Entry control's Placeholder text shifts, but only when on a page that is displayed modally. This is an Android-specific issue.

If you comment out the following line in App.cs, the "issue" goes away, but then some functionality is lost:
NavigationPage.SetHasNavigationBar(page, false);

This is new to 1.2.3-pre3 for you?
Comment 5 Chris Riesgo 2014-09-24 14:38:37 UTC
I believe this is new to 1.2.3-pre3. We were running pre2, I upgraded, then saw this behavior. I couldn't find pre2 in NuGet -- I was going to try rolling back to double check.
Comment 6 Udham Singh 2014-09-25 07:26:58 UTC
I have checked this issue with the help of instructions provided in bug description and observed the same behaviour mentioned in bug description. To reproduce this issue I have followed the steps mentioned below:

1. Download the 'Repro Project' provided in comment 1.
2. Open project 'XF_EntryTextShift' in XS and run this.
3. Click into the Entry control and Placeholder text shifts upward for a very small moment(< 1 sec).
4. Open file 'App.cs' and comment line "NavigationPage.SetHasNavigationBar(page, false);".
5. Run the application and issue goes away (Entry control placeholder text shifts upward).
