我在Top上有一个RelativeLayout，包括EditTexts和一个FrameLayout（就像列表的框架一样），它包含一个ListView。当我在EditText中单击Background时，只要键盘处于活动状态且EditTexts为空，FrameLayout以及所有其他透明区域将变为浅蓝色。当我填充这些EditTexts时，EditTexts周围屏幕的一些不可确定的部分会恢复它们的颜色。如果键盘出现时已经填充了EditTexts，则不会出现效果。
我花了几个小时来研究这个bug，寻找一个提示，但仍然不知道如何缩小范围。我希望我能给你更多的信息，但我不知道什么是相关的。

将android：cacheColorHint属性添加到ur listview
android:cacheColorHint="@android:color/transparent"
答案 1 :(得分：0)
将cacheColorHint属性设置为＃00000000到列表视图 android：cache Color Hint =“＃00000000”
答案 2 :(得分：0)
尝试：
listView.setSelector(android.R.color.transparent);
希望它有所帮助。
