单选按钮不会切换其状态 [英] Radio Button does not toggle its state

问题描述

我在布局中添加了一个RadioButton.

I add a RadioButton in my layout.

开始时未选中.当我单击它时，它变为选中状态(如模拟器中所示).但是当我再次单击它时，它不会再次取消选中吗?

It is unchecked to begin with. And when I click on it , it becomes checked (as shown in emulator). But when when i click on it again, it does not become unchecked again?

<RadioButton android:checked="false"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:id="@+id/option1"/>

推荐答案

如果仅使用一个单选框进行打开和关闭检查，也许应该使用复选框或切换按钮.

If you are only using one radio box for checking on and off, maybe you should use checkbox or toggle button instead.

向下滚动并查看复选框和切换按钮.

Scroll down and see checkbox and toggle button.

使用收音机时，通常有一个以上，并在它们之间进行选择.就像轻松，中等，困难一样.

When using radios you usually have more than one and choose between them. Like easy, medium, hard.
