How to enable slide on the Right of Android listview

Many developers do not know how to enable the quick scroll slider of the listview list control. Here, the android Development Network tells everyone that the secondary scroll slider only needs one row.CodeThis can be done. If you use XML layout, you only need to add the Android: fastscrollenabled = "true" attribute to the listview node. For Java code, you can use mylistview. setfastscrollenabled (true); to control enabling. The false parameter is hidden.
Another point is that when your scrolling content is small and you do not reach the three screen heights of the current listview, this quick scroll slider does not appear, and this method is still the basic method of abslistview, you can use Quick scrolling assistance in listview, gridview, and other subclasses.
