I am unable to modify the layout when opening the keyboard

Question

I’m trying to "decrease" the layout when opening the keyboard, but I’m not getting it, it’s inside a ScrollView and I realized that he ignores the free space below the views (where there are no views), but does not ignore what is above them (here showing the layout with the open keyboard: https://imgur.com/a/T2JPB, There is another edittext down there that doesn’t appear, da para ver isso no xml), can I ignore it when opening the keyboard? I’ve seen in some topics here on the site (this I need to squeeze my layout when I open the keyboard gave the idea of the ScrollView), but none worked, I tried to use the android:windowSoftInputMode="adjustResize" as the answer to this topic https://stackoverflow.com/questions/16411056/how-to-adjust-layout-when-soft-keyboard-appears indicates, with this line or without it the layout is the same thing, someone knows how to solve?
