MainActivity

QuantityInfo info =list.get(position);

QuantityInfo contains three types of information: comment, quanntity, and time. If you specify QuantityInfo as it is, you will not know the location of the method inside, so serialize it.

    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        //Screen transition
        Intent intent = new Intent(getApplication(), DetailActivity.class);
        QuantityInfo info =list.get(position);
        intent.putExtra("QuantityInfo", info);
        startActivity(intent);

    }
}

SubActivity

QuantityInfo info = (QuantityInfo)getIntent().getSerializableExtra("QuantityInfo" );

When intenting, the serialized position of QuantityInfo and QuantityInfo is taken out in info.

time.setText(info.getTime());
comment.setText(info.getComment());
quantity.setText("" + info.getQuantity());

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_detail);
        setTitle("");

        Intent intent = getIntent();
        //Receive value from MainActivity
        QuantityInfo info = (QuantityInfo)getIntent().getSerializableExtra("QuantityInfo" );
