取消选中RadioButtonGroup中的所有RadioButton [英] Uncheck all RadioButton in a RadioButtonGroup

问题描述

我想要实现的是:在活动开始后，我希望没有选中/选中RadioButton.

What I wanted to achieve is this: Right after the activity starts, I want that no RadioButton is selected/checked.

我的问题是:活动开始时，总是选择/选中第一个RadioButton.

My problem is this: When the activity starts, the first RadioButton is always selected/checked.

我在初始化单选按钮之后(在onCreate内)立即尝试了radioButton1.setChecked(false)，但是当活动开始时，我无法手动检查/选择第一个单选按钮.直到选择第二个或第三个单选按钮，现在我才能选择/选中第一个单选按钮.

I tried radioButton1.setChecked(false) right after initialization of the radiobutton(inside onCreate), but when the activity starts, I can't manually check/select the first radiobutton. Till I select the 2nd or 3rd radio button, I can now select/check the first radio button.

推荐答案

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radiogroup);
radioGroup.clearCheck();
