Android ScrollView refuses to scroll to bottom

I have a root scrollview element with a relativelayout in it, and a bunch of form elements inside the relative layout.

For some reason, when the soft keyboard is up it seems unable to scroll all the way to the bottom, which cuts one of my buttons in half.

Here is a screenshot of the hierarchy viewer to demonstrate what I mean.

enter image description here

As you can see, the system knows that the view continues past the keyboard, yet the scrollview (which fills the visible part of the screen correctly) won't continue to scroll down as it should.

I have android:windowSoftInputMode="adjustResize" in the manifest for the activity, and I can/will not switch it to pan.

Any help is appreciated.

edit: I am seeing this in more than 1 view. Here is the xml of another view with the same problem:

I just had this problem with an app and found out that it was due to the ScrollView layout_height being set to wrap content. The issue is that if you have enough content to need a ScrollView, you don't want to wrap the content because the bottom of the ScrollView is off the screen by some arbitrary amount. I didn't have enough data to be affected by this as I didn't need a ScrollView until the keyboard popped up. By the looks of it, the OP was in the same situation.

Now, once the keyboard pops up, the bottom of the ScrollView is raised the same amount as the height of the keyboard and ends up below the top of the keyboard by the same arbitrary amount that it was below the bottom of the visible screen.

Ultimately, my fix was to bind the top of the ScrollView to my toolbar and then right-click the ScrollVIew in the tree and select 'center vertically' (not in parent option). Now works like a charm. The layout_height should automatically go to 0dp.
