What is the difference between setScrollPosition & getTabAt methods of the TabLayout?

Question

What is the difference between tabLayout.setScrollPosition(int, float, boolean); and tabLayout.getTabAt(int); methods?

because, I can also set the tabLayout to indicate to the next by using setScrollPosition, but, the problem with this approach is that this Method does not update the Integer returned by tabLayout.getSelectedTabPosition();

Answer 1

getTabAt : Returns the tab at the specified index.(TabLayout.Tab)

getSelectedTabPosition: Returns the position of the current selected tab. -selected tab position, or -1 if there isn't a selected tab.-

setScrollPosition :

void setScrollPosition (int position, 
                float positionOffset, 
                boolean updateSelectedText)

Set the scroll position of the tabs. This is useful for when the tabs are being displayed as part of a scrolling container such as ViewPager.

Calling this method does not update the selected tab, it is only used for drawing purposes.

position -> int: current scroll position

positionOffset -> float: Value from [0, 1) indicating the offset from position.

positionOffset -> boolean: Whether to update the text's selected state.
