Recyclerview computehorizontalscrollextend computehorizontalscrollrange computehorizontalscroll for calculating the sliding distance

// At present RcyclerView The height of the display area . The horizontal list screen displays from left to right

int extent = recyclerView.computeHorizontalScrollExtent();

// Overall height , Attention is the whole , Included outside the display area

int range = recyclerView.computeHorizontalScrollRange();

// The distance that has been scrolled down , by 0 Hour means it is at the top

int offset = recyclerView.computeHorizontalScrollOffset();

// Percentage that has scrolled [0.0-1.0]

float percentage = (offset / (float)(range - extent))

Here is the picture I drew
