如何在编辑文本上显示单选按钮中的值？

Question

public class AddAppointment extends AppCompatActivity {
    EditText patname,appday,ages,gender;
    RadioGroup rr;
    RadioButton rr1,rr2;
    
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_appointment);
        gender = findViewById(R.id.gender);
        rr = findViewById(R.id.rr);
        rr1 = findViewById(R.id.rr1);
        rr2 = findViewById(R.id.rr2);
        rr.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Integer id = rr.getCheckedRadioButtonId();
                String g = id.toString();
                if (rr1.isChecked()) {
                    gender.setText(g);
                }else if(rr2.isChecked()){
                    gender.setText(g);
                }
            }
        });

**我要求男性和女性在各自的单选按钮rr1和rr2中，当任何选择时，应该在edittext(性别)中显示结果**

我不确定我是否理解了你的问题。是否希望在选中rr1时编辑文本显示“Male”，在选中rr2时显示“Female”？

如果是这样的话，我非常确定下面的代码将会做到这一点：

rr.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {
            // rr1 = Male; rr2 = Female
            if (radioGroup.getCheckedRadioButtonId() == rr1.getId())
                gender.setText("Male");
            else
                gender.setText("Female");
        }
    });
