如何使用视图绑定从单选组获取选中的 id 的文本?

How to get text of the checked id from radio group using view binding?

我已经完成 this 并找到了一个共同的答案,即

        int selectedId = radioGroup.getCheckedRadioButtonId();

        radioButton = (RadioButton) findViewById(selectedId);

        Toast.makeText(MyAndroidAppActivity.this,
            radioButton.getText(), Toast.LENGTH_SHORT).show();

但是如何使用视图绑定获取文本?

你可以这样做:

编辑:

int id = binding.radioGroup.getCheckedRadioButtonId();
RadioButton radioButton = binding.getRoot().findViewById(id);
//Then get the radio button's text
Toast.makeText(MyAndroidAppActivity.this,
        radioButton.getText(), Toast.LENGTH_SHORT).show();
