在Expandable中将背景颜色设置为空edittext和特定标题

Question

我必须指出用户一旦用户点击保存按钮，这个编辑文本是留空的标题下，通过设置背景颜色的标题和编辑文本，但它不工作。我已经找过了，但没有得到任何解决方案。请帮帮忙。提前谢谢。

下面是我用来设置edittext的背景颜色的代码，但它给其他子对象中的其他edittext着色。

    }

在设置一个标题的背景时，滚动背景也设置为许多其他标题。

Answer 1

使用setTag和getTag convertView您的问题将会得到解决。

Answer 2

最后，我通过将特定视图设置为红色，将所有其他视图设置为白色，解决了这个问题。为此，我检查了空的edittext，如果它设置为红色或白色。在滚动时也能正常工作。
