默认值

public class MainActivity extends Fragment {

   public static final String TAG = MainActivity.class.getSimpleName();

   private String isShowIndex = "0";
   private View mView;

此默认值"0"决定Activity首先显示哪个菜单页，注意这里直接改下面的相对的值是不可行的，必须要直接改定义 private String isShowIndex = "0";的值

// 右侧菜单过来
       if ("0".equals(isShowIndexParams)) {
           Constants.mRadioGroup.check(R.id.main_home);
           isShowIndex = "0";

       } else if ("1".equals(isShowIndexParams)) {
           Constants.mRadioGroup.check(R.id.main_search);
           isShowIndex = "1";

       } else if ("2".equals(isShowIndexParams)) {
           Constants.mRadioGroup.check(R.id.main_new);
           isShowIndex = "2";

       } else if ("3".equals(isShowIndexParams)) {
           Constants.mRadioGroup.check(R.id.main_shopcar);
           isShowIndex = "3";

       } else if ("4".equals(isShowIndexParams)) {
           Constants.mRadioGroup.check(R.id.main_center);
           isShowIndex = "4";

//       } else {
//           Constants.mRadioGroup.check(R.id.main_home);
//           isShowIndex = "2";
       }

   }
