TextView measurement error after rebinding ViewHolder.

Sometimes view measurement doesn't update.

bugged measurement

               Fetched  D  position 82
                        D  82 was cached true
                        D  height 161
           measurement  D  params height -2
                        D  height 161

Correct measurement

               Fetched  D  position 82
                        D  82 was cached true
                        D  height 161
           measurement  D  params height -2
                        D  height 218

Maybe related to #55.

Further investigation reveals sometimes the views are just not being measured, though the call through recycler view is being made. There must be some residual state stopping measurement. What can stop measurement?

[TonicArtos]

Okay, so this is a problem caused by internal measurement logic in TextView. TextView will not measure itself again if it believes there has been no change to its content. As recycler view sets exact dimensions for the non scrolling axis, this crops up whenever a text view has been rebound and the width is to be changed. The workaround to force TextView to measure itself again by some method.

[TonicArtos]

One solution is to not use the match_parent value for layout_width for TextViews that are in a view group.

[TonicArtos]

Another is to use different viewTypeIds for views intended for different layouts.

So far I have been unable to work around the problem from the SuperSLiM end of things. :(

[TonicArtos]

Closing for now, people can resurrect this if they want to look into it again.

Maybe leave this open so people can see/contribute, or make a note of it in the docs?

[TonicArtos]

I was going to note it in the docs, but sure, I'll leave it open too.

Maybe report this as an issue to AOSP issue tracker?

[TonicArtos]

I don't think it is a bug. I mean, TextView and RecyclerView are both doing the correct thing. For now, I don't plan on doing anything about this, but in the future I might see if there is something I can do; patching RecyclerView, or perhaps some kind of change to SuperSLiM.
