Question

我有一组三个RadioGroup，每个组由三个RadioButtons组成。还有一个重置按钮，用于将所有组中的所有RadioButton设置为false（setChecked（false））。

重置工作正常（所有RadioButtons都未选中），但重置后，在每个RadioGroup中，只有那两个按钮可以被检查，在点击重置按钮的时刻没有检查。只有这样，才能再次检查组中的所有三个按钮。

我尝试在重置期间添加setFocusable（true）和setClickable（true），但这没有什么区别。那么焦点或可点击性还有什么可能导致这种情况以及如何解决？

我定位Android API 7。

Answer 1

在这里找到了：

android radiobutton check after clearing check issue

对于每个单独的Button，应该使用radioGroup.clearCheck（）而不是radioButton.setChecked（false）。

Answer 2

RadioButton组强制执行此规则：任何时候只选择一个选项。你不应该取消选中或检查多个。 CheckBox专为此类用途而设计。

重置后无法选择先前选择的单选按钮
