This tutorial will teach you to make a small Fish shop Inventory system using android studio. The following app will use to manage the Fish shop.The app is developed steps ahead of the existing world. While app development will be very useful for the future as well.
We made the layout design
activity_main.xml

String item = s1.getSelectedItem().toString();
double qty = Double.parseDouble(ed1.getText().toString());
if(item.equals("Kg"))
{
double cal = (qty * 140) ;
ed2.setText(String.valueOf(cal));
}
else
{
double cal = (qty/1000 * 140) ;
ed2.setText(String.valueOf(cal));
}
}
});
}
}
I have attached the video tutorial below it will help you to do this step by step.
