android - 如何在android中获取单选按钮的选定(整数)id

Question

但是我正在获取唯一 ID，但不知道如何获取 1,2 这样的 ID...我已经在下面发布了我的代码...

public void onCheckedChanged(RadioGroup group, int checkedId){      
    Global.id=(int)buttongroup.getCheckedRadioButtonId();               
    System.out.println("selected Global Id:"+Global.id);                
    System.out.println("selected id"+Global.id);                
    btn=(RadioButton)findViewById(Global.id);               
    btn.setChecked(true);               
    Global.buttonname=(String)btn.getText();                
    System.out.println("selected radio button"+Global.buttonname);              
}

02-25 14:59:38.042: I/System.out(8717): selected Global Id:2131427346

你可以打开id:

switch(checkedId) {
  case R.id.name_of_fist_radiobutton:
   /// my operation form 1;
   break;
   case R.id.name_of_second_radiobutton:
   /// my operation form 2;
   break;
}
