Variable ၂ခုပါ equation ကို ေျဖရွင္းနည္း
============
ax + y = c
x + by = d
(a, b, c, d, x, y ေတြဟာ double value ေတြျဖစ္ပါတယ္။ )
နည္းလမ္း (1)
==========
double y1 = (d - c/a) / (b - 1/a);
double x1 = (c - y1) / a;
နည္းလမ္း (2)
==========
double y2 = (c - a*d) / (1 - a*b);
double x2 = d - b*y2;
==========

Android Spinner (Drop Down) Example

Image
This tutorial is about the Android spinner, which is a drop down list. In this example, we will learn to populate the Android spinner. Then we will display some content corresponding to the spinner element click (we will handle the spinner onclick event). Spinners provide an easy and elegant way to select one value from list of values. By default, a spinner shows its current selected value. On touching, the spinner will display a drop down list containing all other available options from which the user can select a new value. Android Spinner Example In this spinner example, we are displaying a list of users inside the spinner. On clicking the spinner, a drop down list containing users will be displayed. When you click on any user (spinner item), the details corresponding to that user will be displayed in the fields below. So you will also learn how to handle the click event. XML layout file: Create a new file activity_main.xml The spinner is used to hold a
