Android Generating Random Number and Random Color with range in java
Today I will let tell you how to get a random number in android with just 2 to 3 line of code. so there is a built-in function in a Java language called random function this function help use to get random number every time we call it.
To get the idea of here is the sample code
we have created an object of random function now if we want to get Integer number simply add
this will add some random number to your variable. Now let's create a random number with a minimum and maximum range
there is a formula for it ((max-min) + 1) + min) . let's understand this formula with an example
this code will return you number range from 100 to 200
Now same method we will you to get random color.
so that is it for today.
Thank you for your time.
To get the idea of here is the sample code
[Random random = new Random();]
we have created an object of random function now if we want to get Integer number simply add
[int i = random.nextInt()]
this will add some random number to your variable. Now let's create a random number with a minimum and maximum range
there is a formula for it ((max-min) + 1) + min) . let's understand this formula with an example
[
final int min = 100;
final int max = 200;
Random random = new Random();
int i = random.nextInt((max - min) + 1) + min;
]
this code will return you number range from 100 to 200
Now same method we will you to get random color.
[
private int getRandomColorCode() {
final int min = 160;
final int max = 256;
Random random = new Random();
return Color.argb(150, random.nextInt((max - min) + 1) + min,
random.nextInt((max - min) + 1) + min,
random.nextInt((max - min) + 1) + min);
}]
so that is it for today.
Thank you for your time.
