Keyboard hide leaves empty blank space

Question

I have an issue like after my keyboard pops up and hides there is an empty space where ever the keyboard was. I have nothing but few components inside ScrollView.

</LinearLayout>

</ScrollView>

And ScreenShot of it.

I didn't find any reason yet why this is happening. Any Help will be helpful.

NOTE : I Googled enough to find the solutions, adding the windowBackground in styles.xml didn't help. And I don't find valid reason to use that.

I also tried without adding TextInputLayout. But the result was same.

Happening in all versions of Android.

Answer 1

I managed to figure it out after breaking my head. This was happening due to android.support.design.widget.CoordinatorLayout which I used in activity.

The above xml is a fragment attached to the MainActivity. In Main Activity XML I have CoordinateLayout as parent. I think there might be some bug with using CoordinateLayout along with ScrollView.

Changing it to LinearLayout fixed my issue for now.
