android:cacheColorHint=”#00000000″属性[ListView]

ListView是常用的显示控件,默认背景是和系统窗口一样的透明色,如果给ListView加上背景图片,或者背景颜色时,滚动时listView会黑掉,原因是,滚动时,列表里面的view重绘时,用的依旧是系统默认的透明色,颜色值为#FF191919,

自定义listview的时候,当你不使用android:cacheColorHint=“#00000000”会出现下面选中一个空间黑色底色的情况,破坏整体美观度:

要改变这种情况,只需要调用listView的setCacheColorHint(0),颜色值设置为0  或者xml文件中listView的属性 Android:cacheColorHint=”#00000000″ 即可,滚动时,重绘View的时候就不会有背景颜色
设置前                                                                                                      设置后

设置前设置后

当你不使用android:listSelector属性,默认会显示选中的item为橙黄底色,有时候我们需要去掉这种效果:

android:listSelector=”#00000000″
进行上面的设置之后,ListView点击item时就没有任何现象了.
