android - I want to send data from recyclerview adapter from fragment to fragment opening new fragment

Question

I want to send data from RecyclerView adapter to new Fragment. I succeeded in doing so, but why was the result of the collision in the previous fragment?

the least your attention is very big and meaningful to me :)

as shown below:

I want the fragment to open up new fragments like WhatsApp, Instagram, etc.

Answer 1

Solution 1:

In the code where you replace HomeDetailFragment, call addToBackStack() like this

fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frame_fragmenthome, fragmentDetail);
fragmentTransaction.addToBackStack(null);    // add this line to your code
fragmentTransaction.commit();

Here is a short explanation from android developer docs for Providing Proper Back Navigation.

When there are FragmentTransaction objects on the back stack and the user presses the Back button, the FragmentManager pops the most recent transaction off the back stack and performs the reverse action (such as removing a fragment if the transaction added it).

Solution 2:

If there is no hard-and-fast requirement to use fragments, then I would recommend using HomeDetailActivity instead of HomeDetailFragment.

Most of your above code will remain the same except you will be calling an Activity(via an intent) instead of a Fragment.

This has certain advantages like you don't have to deal with fragmentManager or fragment backStack. In your case it's quite easy to implement.
