I put the picture of the fragment interface directly in the textview, you can use the list view to place it, and then rewrite the adapter to realize clicking the corresponding picture to jump to the interface you specified!
ps: I only placed a fragment of the game classification interface, the rest is the same, if there are any errors in the code, please correct me, I will correct it in time, thank you, let us learn together and make progress together!
