This is a template for Professional Calculations app.
Basic calculation only requires input boxes for end users to key in some values, labelled appropriately, and output (result) can be displayed with auto copy to clipboard.
A X [B] = C
A - user key input (number decimals)
[B] is a value that belongs to B when user SELECT
Template :
SPINNER (also known as Drop-down select/menu)
SELECT item by Name/label, obtain value v
Example below:
1. Construction professional needs to calculate the weight of steel by total length and steel type [Reinforcement]
As the developer, you NEED to create STRINGS and VALUES obtained from engineering tables.
2. Roof surface area = Floor surface area X 1/cos(angle of roof)
public class reinforcement extends Activity implements OnItemSelectedListener, OnClickListener {
Spinner spinnerOsversions;
