Find difference between two TextBoxes

Hello all. Firstly sorry for my bad english. I'm from Ukraine.

Secondly - I have two project. And both have TextBox.

In both project TextBox higher (on Y сoordinate) then 190px.

When I compile and launch first project on Android - all works alright, but when compile and launch second project - appears a bug. The problem is that when I tap on TextBox - keyboard is displayed and hide back in that moment.

First project haven't this bug, but that TextBox look like TextBox in second project.

Please, help me, and find what is the difference between TextBoxes.

Thank You.
