The background turns black when the custom background of Android listview is rolled back

Listview is a commonly used display control. The default background is the same transparent color as the system window. If a background image or background color is added to listview, The listview will be black when scrolling, because, during scrolling, when the view in the list is re-painted, the system still uses the default transparent color. The color value is # ff191919. to change this situation, you only need to call setcachecolorhint (0) of listview and set the color value to 0 or the listview attribute in the XML file.Android: Cachecolorhint = "#00000000". The background color is not displayed when the view is re-painted during scrolling.
