Android Question Who Know This Bug?

I dont understand the question. You need to describe it much more clearly.

You really should give us more informations! Upload your project so we can run it and see the problem.

Sorry, the problem is edittext if for example i open activity, the screen on my android does not appear as the first show. So when i will type the word not visible on the screen

hehehe sorry reonell

In the IDE use File-Export as ZIP

Upload this zip

I think the problem is that the keyboard is covering the input field...

OP have you seen https://www.b4x.com/android/forum/threads/handle-the-soft-keyboard-with-the-ime-library.14832/

Making note of the text

"Handling the screen size changed event
When the keyboard opens the available screen size becomes much shorter. By default if the EditText is located near the bottom of the screen, Android will "push" the whole activity and make the EditText visible. This mode is named "adjustPan" mode.

By calling IME.AddHeightChangedEvent you are changing the activity to "adjustSize" mode. In this mode the activity will not be pushed automatically. Instead the HeightChanged event will be raised when the keyboard is shown or hidden."

But you need to enable your Activity to handle this... if it is fullscreensize you may well need to do something else..
