Answer 1

You dont need to show "Load More" Button always. You can use Android's Recycler View for this. It will load only the data which can be shown on screen. Rest of the data will be loaded as you scroll down. And the view which is scrolled up (Vanishing views) are recycled automatically.

First link question have a simple answer, If you made a custom adapter for populating listview then there will be a getCount() method which will return the number of items you want to show on listview. if you have not getCount() method then simply override it.

there i(variable) have that value which number if items you want to show on listview, on refresh button click increment the value of i(variable) that will again refresh the whole listview and add the total number of items in listview which is the value of i(variable)
