                </LinearLayout>

        </LinearLayout>
    </HorizontalScrollView>
</LinearLayout>

I have no ideas, what's it can be. I use Android 2.3 and IntelliJ IDEA Community Edition 12.0.4.

I hope my answer can still help someone. I had the same problem in Android 6.0, the error is because it cannot inflate the view due to a problem in the ImageButton, in its attributes android: background or android: src since in these you can refer to drawable, where the problem is triggered, since from Android Studio 1.4 the folders for design elements (v21), (v24) are handled , etc, and it is very common not to put the images or backgrounds in the drawable folders correctly.

res
--- drawable
--- drawable(-v21)
--- drawable(-v24)

This problem can occur in any object that uses the android: background or android: src attributes referring to the drawable folder.

Solution:
In the ImageButtons of the example, in its attributes android: src, it refers to back and device_access_sd_storage

<ImageButtons
.....
android:src="@drawable/back"
.....
<ImageButtons
.....
android:src="@drawable/device_access_sd_storage"
.....

We look for these elements back and device_access_sd_storage in these directories drawable (-v21), drawable (-v24), ....

res
--- drawable(-v21)
--- drawable(-v24)

then we copy it or move it to this directory drawable

res
--- drawable\

We run the APP again and the error would be resolved.

In your ImageButton need replace

android:src="@drawable/back" to app:srcCompat="@drawable/back"

and add to your Gradle file

defaultConfig { vectorDrawables.useSupportLibrary = true }

Are you sure back, device_access_sd_storage, and collections_view_as_list are all png images in your drawable folder? It complains that one or more of these ids are invalid.
