A radio button is a two-states button that can be either checked or unchecked. When the radio button is unchecked, the user can press or click it to check it. However, contrary to aCheckBox, a radio button cannot be unchecked by the user once checked.
单选按钮是一种特殊的双态按钮,其有选中和为选中2种状态。当单选按钮未被选中,则用户可以按下或点击它,以选中它。然而,与CheckBox不同的是,用户一旦选中了它,就不能取消对它的选中。

Radio buttons are normally used together in a RadioGroup. When several radio buttons live inside a radio group, checking one radio button unchecks all the others.
通常多个单选按钮在一个RadioGroup中一起使用。当多个单选按钮在一个RadioGroup中是,选中一个单选按钮,则其它的单选按钮将被取消选中。
