How many times does ListView slide a page? Use the paging list !, Listview is uncomfortable

Scrolling positions such as ListView often do not meet user expectations:

Most of the time I want to slide to the next page after reading a page, but it is difficult to control the sliding distance.

 

PageScroller is provided in the PagedListView project to solve this problem.

You can use PageScroller to scroll a page at moderate or low speed. If you slide slowly or quickly, the page is processed by default.

 

The usage is as follows:

1. initialize PageScroller

pageScroller = new PageScroller(lvListView);pageScroller.init();

 

2. Override the dispatchTouchEvent Method

In the dispatchTouchEvent method of the Activity, pageScroller. dispatchTouchEvent (ev );

@Overridepublic boolean dispatchTouchEvent(MotionEvent ev) {     pageScroller.dispatchTouchEvent(ev);     return super.dispatchTouchEvent(ev);}

 

 

 

The project also provides several demos, such as ListViewActivity.
