work_weipa_radiobutton切换fragment

问题：如何使得fragment切换时，radiobutton也跟着变化？

回答：通过设置属性setChecked(true)

例子：

main_tab_login.setChecked(true);

List<Fragment> fragments = fragmentManager.getFragments();
		if (null != fragments) {
			for (Fragment fragment : fragments) {
				if (null != fragment) {
					if (!tag.equals(fragment.getTag())) {
						fragmentManager.beginTransaction().hide(fragment).commit();
					}
				}
			}
		}
