将Android ListView显示为页面

Question

I have a listview where I'm displaying items as pages with 3 items per page. Depending on user clicking prev or next buttons I am scrolling through the listview using setSelection . Here is the code:

int size = listView.getCount(); 
int scrollToPosition = 0;
if(direction == PREV)
    scrollToPosition = listView.getFirstVisiblePosition() - 3;
else
    scrollToPosition = listView.getFirstVisiblePosition() + 3;
if(scrollToPosition < 0) { scrollToPosition = 0; }
else if (scrollToPosition >= size) { scrollToPosition = size - 1; } 
listView.setSelection(scrollToPosition);

With this approach, if I have 4 items in the list, the first page shows items 1,2,3 and page 2 shows items 2,3,4. I need to change this such that page 1 shows 1,2,3 and page 2 shows only the 4th item. How do I change this?

您必须为不同的页面制作不同的元素数组。例如arr1应该包含元素1,2,3和arr2应该包含4并填充页面1的arr1和页面2的arr2
