Answer 1

You put int in "Value" and try to get it from "value" of course you will get null, both should be "Value" or "value"

change this

 Intent intent = new Intent(getActivity(), ButtonCountActivity.class);
            Bundle bundle = new Bundle();
            bundle.putInt("Value",i);
            startActivity(intent);

to this

  Intent intent = new Intent(getActivity(), ButtonCountActivity.class);
             
                intent .putExtra("Value",i);
                startActivity(intent);

change this ..

Intent intent= getIntent();
    Bundle bundle = new Bundle();
    bundle = intent.getBundleExtra("value");
    int value = bundle.getInt("value");
    Log.d("T","haha got u " + value  );

to this

int value;
 Bundle extras = getIntent().getExtras();
        if (extras != null) {
                   value = extras.getInt("Value");

               }
