如何将数据从活动发送/传递到TabLayout / ViewPager片段
我有问题将数据传递给TabLayout / ViewPager包含Fragment，
我试图发送使用捆绑buat dosen't工作，我试图从goole serching我没有找到任何与我的问题相同的答案，另一个arround谷歌只是将数据传递到片段在活动中没有TabLayout / ViewPager和那里所有是静态标签。
在我的案例中，我尝试使用日历制作Recyleview和Filtering，所以我把所有的一天都放在TabLayout上，就像这个截图
屏幕截图用户界面，暗区是查看寻呼机，底部的红色标签是TabLayout，包括与所选月份相同的标签
因此，如果你引用我使用Bundle或Fragmment Communication，请告诉我在哪里必须放置我的脚本。请看下面我的剧本
我删除了bundel脚本
来自Tab布局的此活动父级，您可以将其称为主活动
public class daftar_jadwal extends FragmentActivity {
