我想将 RadioButton 的可见性设置为 INVISIBLE 或 GONE。由于某种原因，这不起作用。

RadioButton myRadioButton = (RadioButton) findViewById(R.id.my_radio_button_id);
myRadioButton.setVisibility(View.GONE);

或者

myRadioButton.setVisibility(View.INVISIBLE);

没有返回错误，它只是不做任何事情。

但是我在 RadioGroup 上试过这个

RadioGroup myRadioGroup = (RadioGroup) findViewById(R.id.radiogroup_quiz_answers);
myRadioGroup.setVisibility(View.INVISIBLE);

它可以很好地隐藏整个组。有没有办法只隐藏一个 RadioButtons？我有一组 3 个是问题的答案，但在某些情况下我想隐藏最后一个。

您可以通过这种方式隐藏特定的单选按钮

RadioButton myRadioButton = (RadioButton) findViewById(R.id.last_radio);
myRadioButton.setVisibility(View.INVISIBLE);

或者如果您使用 View Gone menas 单选按钮 hide with sapce

RadioButton myRadioButton = (RadioButton) findViewById(R.id.last_radio);
myRadioButton.setVisibility(View.GONE);

在这种情况下，不要隐藏广播组

RadioGroup myRadioGroup = (RadioGroup) findViewById(R.id.radiogroup_quiz_answers);
myRadioGroup.setVisibility(View.Visible);

你好，像这样使用。

RadioButton myRadioButton = (RadioButton) findViewById(R.id.my_radio_button_id);
myRadioButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            myRadioButton.setVisibility(View.INVISIBLE);
        }
    });

或者

  <RadioButton
        android:id="@+id/radio0"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="RadioButton" 
        android:visibility="invisible"/>

这段代码对我有用。希望这会对你有所帮助。
