Coding the Fragment classes to use the DataManager class

Add this highlighted code to the InsertFragment class to update the onCreateView method:

View v = inflater.inflate(R.layout.content_insert, 
   container, false);
final DataManager dm = 
   new DataManager(getActivity());
Button btnInsert = 
   v.findViewById(R.id.btnInsert);
   
final EditText editName = 
   v.findViewById(R.id.editName);
   
final EditText editAge = 
   v.findViewById(R.id.editAge);
btnInsert.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
          dm.insert(editName.getText().toString(),
                       editAge.getText().toString());
   }
}...
