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();}}}}
