To change the background, it is easy to prepare an image and specify the attribute android: background = "@ drawable/bg", but don't be too happy. When you do this, you will find that the background has changed, but when you drag, you can also click the blank position in the list to find that all listitems are black, damaging the overall effect.

If you only change the background color, you can directly specify the android: cacheColorHint as the color you want. If you use an image as the background, you only need to change the android: cacheColorHint is specified as transparent (#00000000 ).

 

The fourth divider attribute is used to set an image between each item as an interval or remove the split line between items.

Eighth attribute fastScrollEnabled,

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 can be done with only one line of code, 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.
