推荐答案

我认为更好的方法是使用 RadioGroup 并在此设置监听器以更改和更新 View 相应地(为您节省 2 或 3 或 4 个等侦听器).

I'd think a better way is to use RadioGroup and set the listener on this to change and update the View accordingly (saves you having 2 or 3 or 4 etc listeners).

    RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
    radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() 
    {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // checkedId is the RadioButton selected
        }
    });
