ListView拖动时,背景颜色会变成黑色
通过查找API 文档找到这个函数
public void setCacheColorHint (int color)
Since: API Level 1When set to a non-zero value, the cache color hint indicates that this list is always drawn on top of a solid, single-color, opaque background. Zero means that what's behind this object is translucent 透明的 (non solid) or is not made of a single color. This hint will not affect any existing background drawable set on this view ( typically set via setBackgroundDrawable(Drawable)).
Parameters
color The background color
所以我将这个颜色设置为全0即可
解决方法1:
是在ListView xml文件中加入以下属性即可:
Android:cacheColorHint="#00000000"
解决方法2:
代码中写明listview.setCacheColorHint(0);这样就不会出现这种情况了。
