Android 一次只选择一个单选按钮

当我点击

TextView

reference时，我得到了

AlertDialog

builder，因为我用

单选按钮显示了
employeesNames
。现在，当我选中错误的
员工
并想选择另一名
员工
时，应该取消选中错误的
员工
姓名，通过选择一名
员工
，应该启用
确定
按钮

delivery.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            LayoutInflater inflater1 = (LayoutInflater) ct.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View v1 = inflater1.inflate(R.layout.activity_employees_list_for_pop_up, null);
            RadioButton employeechecked = (RadioButton) v1.findViewById(R.id.employeeChecked);
            final Button ok = (Button) v1.findViewById(R.id.do_ok);
            Button cancle = (Button) v1.findViewById(R.id.do_cancle);
            ok.setEnabled(false);
            listView = (ListView) v1.findViewById(R.id.employeePopUpList);
            employeePopUpAdapter = new EmployeePopUpAdapter(ct, employeeIdNameBeans);

            employeechecked.setOnCheckedChangeListener(new );


            listView.setAdapter(employeePopUpAdapter);

            AlertDialog.Builder builder;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                builder = new AlertDialog.Builder(ct, android.R.style.Theme_Material_Dialog_Alert);
            } else {
                builder = new AlertDialog.Builder(ct);
            }
            builder.setView(v1);
            builder.create().show();
            clearListView();
            update();
        }
    });

请帮助我进行编码。不要发表我不理解的理论。我是初学者。

你可以尝试使用RadioGroup而不是RadioButton

<RadioGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:id="@+id/a"
    android:onClick="onRGClick">

    <RadioButton
        android:text="Normal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/a1" />

    <RadioButton
        android:text="Tidak normal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/a2" />

</RadioGroup>

您必须使用RadioGroup，或者通过编程来处理它。我如何才能将RadioGroup用于listview？请将问题再读一遍，这样您就可以使用android checkable listview了

radiogroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        if (checkedId == R.id.a1) {
            // do your stuff
        } else if (checkedId == R.id.a2) {
            // do your stuff
        }
    }
});
