How to set position:fixed in android?

Question

In my app, there is a login and password field near the middle of the screen. I have this in the manifest

android:windowSoftInputMode="adjustResize|stateHidden"

So that the fields are still visible when the keyboard is showing. But the problem is, there is a textview that is bottom aligned, and when the keyboard shows, this view overlaps with the login button under the username/password fields, is there a way, so set that textview field to not be affected by the adjestResize?

Thanks.

EDIT:
Apparently a member of the Android team said there is no direct way to do this. I searched for "android check if keyboard is visible" on Google and got the following answered question: How do I Detect if Software Keyboard is Visible on Android Device?

According to the linked answer, you can detect it indirectly by checking if the window size changed in #onMeasure. See How to check visibility of software keyboard in Android?
