         RadioButton的集合,提供多选一的机制
         属性:
      android:orientation="horizontal/vertical"
              vertical     垂直排布
              horizontal     水平排布          决定当前RadioGroup中RadioButton以什么形式排列
     
    private RadioGroup rg ;
            @Override
            protected void onCreate(Bundle savedInstanceState) {
                   super.onCreate(savedInstanceState);
                   rg=(RadioGroup) findViewById(R.id. radioGroup1);
                   //实现RadioGroup的监听事件
                   rg.setOnCheckedChangeListener( new OnCheckedChangeListener() {
                          @Override
                          public void onCheckedChanged(RadioGroup group, int checkedId) {
                                // TODO Auto-generated method stub
                                switch (checkedId) {
                                case R.id.radio :
                                      System. out.println();
                                       break;
                                case R.id.radio0 :
                                      System. out.println();
                                       break;
                                case R.id.radio1 :
                                      System. out.println();
                                       break;
                                default:
                                       break;
                                }
