Different Viewtypes #42

Closed ghost closed 7 years ago

ghost commented 7 years ago

I am using 2 different viewtypes (a textview and a cardview) for the recyclerview. When the type is changing in the recyclerview while scrolling it is lagging (scroll bar is jumping up and down like crazy). In getSectionedName I'm is always returning "A" Any fixes?

Currently this library assumes all items are of equal height. This limitation is brought about because there's no non-trivial way to determine what the total height of all the views in the RecyclerView will be, so then there's no way to determine what the current position of the FastScroll should be.

Edit: This is now supported using the MeasurableAdapter interface (see Readme). Your RecyclerViewAdapter is still required to have ViewHolders with determinate heights. In other words, you'll need to be able to tell Adapter what the height of a specific ViewHolder is, before it is drawn on screen.
