Dynamic switching of fragments

Issue

My Activity contains two buttons (Next and Back) and a fragment. When the Activity starts, it gets an array of resources. Such as {"Fish", "Bird", "Animal"}; Or this {"Fish", "Bird", "Animal", "Bird", "Bird"}; etc. Depending on the contents of the array, the Next button should switch the fragments accordingly: So: Fragment_Fish.java >Fragment_Bird.java>Fragment_Animal.java. So: Fragment_Fish.java >Fragment_Bird.java>Fragment_Animal.java. >Fragment_Bird.java>Fragment_Bird.java>

How is it easier to implement in Java, please tell me?

Solution

1. You need to make an array of the fragments like this:

Fragment[] fragments = new Fragment[]]{new Fragment_Fish(), and other fragments separated with commas};

2. Make a int variable in the class something like this:

int counter = 0;

3. Increase the counter on button click and update the fragment. Like this:

buttonNext.setOnClickListener(v -> {
   counter ++;
   if(!counter >= fragments.size()){
      //all the fragments are opened do what you need
      return;
   }
   final FragmentTransaction ft = getFragmentManager().beginTransaction(); 
   ft.replace(R.id.details, fragments[counter]); 
   ft.commit(); 
   //came to another fragment
});
