Black Background During listview dragging

Source: Internet
Author: User

Android provides multiple implementation methods for ListView to make the displayed content more beautiful through custom display layout, but we will find such a problem. When we operate ListView, if you do not use the upper and lower buttons on your phone, you can drag the view by touch to find that the background of ListView is black and all selected text becomes dark.

In fact, this problem occurs because the ListView has a cache color mechanism, so we can solve this problem by setting the cache color to transparent.

A. Set by layout attributes (directly defined in the attributes of ListView)

Android: cacheColorHint = "#00000000 ″

B. Set it directly in the code

ListView. setCacheColorHint (Color. TRANSPARENT );

In this way, the black problem can be solved.
