CodePudding user response：

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");

               }
