ExpandableListView的项目混合在一起
Mov*_*aev 6 android expandablelistview
所以我已经将这个应用程序用于梦想分析,它在手机上运行得非常好,但在平板电脑上,探索中的信息可以融合,如下图所示.
也就是说,当你点击它应该隐藏/显示它的子组时,但正如你所看到的,在平板电脑上它只是继续一个接一个地绘制信息,就像显示器不会刷新其内容,我不知道是什么要做,所以请你帮忙.

好吧，我找到了答案，就是 - 你应该显式地为布局设置背景，无论你将其设置为 explist 还是 root 元素并不重要，它只是必须设置。
除非我在保存 explist 的活动布局中设置了背景，否则它不会开始使用任何建议的解决方案。
有趣的问题 - 为什么这有效？！
