Question

我正在尝试在对话框中显示广播组，当单击单选按钮时，它将以共享首选项设置一些数据。当点击任何按钮时我能够做吐司，但是当我点击不同的按钮时我想做点什么。我尝试在单选按钮中设置Onclick但它不起作用。我正在尝试向here学习这是我的对话类

 public Activity c;
public Dialog d;
public Button yes, no;
public RadioGroup radioGroup;
public RadioButton radioButton;

public CustomDialogClass(Activity a) {
    super(a);
    // TODO Auto-generated constructor stub
    this.c = a;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.custom_dialog);
    yes = (Button) findViewById(R.id.btn_yes);
    no = (Button) findViewById(R.id.btn_no);
    yes.setOnClickListener(this);
    no.setOnClickListener(this);
    Radioactive();
}

private void Radioactive() {
    radioGroup = (RadioGroup) findViewById(R.id.radio);
    int selectedId = radioGroup.getCheckedRadioButtonId();
    radioButton = (RadioButton) findViewById(selectedId);




}

我只是想知道在选中特定单选按钮时如何做某事。
