Hello everyone wanted to know if I can support, I have a project in which I have implemented a tablayout with 3 tabs, each tabs I have assigned a fragment, for the first tab I have a listfragment and show the list correctly, but selecting an element of the list want the switch to another fragment that will also display another list.
For example I have a list of categories, in the fragment of listfragment type in the first tab, but selecting an item from the list I want to show the items child of that category in another list, but in the same tab, reached the code, as managing that change, ie another fragment listfragment call type from listfragment.
