Let's say you have 4 items within a viewpager...you select item #2...upon re-entry from another fragment back to this viewpager, even though you've set your current item to #2 (index = 2), the underline strip resides under the item #3 tab...

Here is the suspected code in question:

// if there is an offset, start interpolating left and right coordinates between current and next tab
if (currentPositionOffset > 0f && currentPosition < tabCount - 1) {

        View nextTab = tabsContainer.getChildAt(currentPosition + 1);
        final float nextTabLeft = nextTab.getLeft();
        final float nextTabRight = nextTab.getRight();

        lineLeft = (currentPositionOffset * nextTabLeft + (1f - currentPositionOffset) * lineLeft);
        lineRight = (currentPositionOffset * nextTabRight + (1f - currentPositionOffset) * lineRight);
    }

lineLeft and lineRight aren't set correctly in this scenario...any ideas on how to fix this?
