如何在编辑文本上显示单选按钮的值？

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);
                }
            }
        });

**我在各自的单选按钮 rr1 和 rr2 中要求男性和女性，当任何选择时，应在 edittext(gender) 中显示结果**

Answer 1

我不确定我是否理解您的问题。您是否希望编辑文本在选中 rr1 时显示“男性”，而在选中 rr2 时显示“女性”？

如果是这样，我很确定以下代码可以做到这一点：

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");
        }
    });
