Layout content is not showing after update 2.0.1 -> 2.0.4 (2.0.3) about constraintlayout HOT 5 CLOSED

The issue might be caused by a bug in the ratio optimization. If instead of app:layout_constraintDimensionRatio="h,1:1.3" you simply set it to app:layout_constraintDimensionRatio="1.3:1" everything works. In this case, the "h,1:1.3" is also not super meaningful as the other dimension is a wrap_content, so only one side will use the ratio.

Yeah, same here. Some views disappeared after the update from 2.0.1 to 2.0.4.

EDIT:

Happens on 2.0.2 and 2.0.3 too.

This seems to be an issue with the optimizer, let me look into it.
I can get your view to work by setting optimizationLevel = 0 in KeyboardView.kt.

Note: a likely more optimized way would be to use match_parent instead of 0dp in item_keyboard.xml for the width.

Fixed in tip of tree.
