Kotlin Methods Example

-
  1. Simple Function. neither accepts nor return any variable or value
    fun helloWorld(){
  println("Hello World")
}
  2.  Function that takes a parameter but returns no value
    fun stringFunction (text : String){
 for (c in text){
   println("$c ") //KOTLIN -> K O T L I N
 }
}

fun intFunction(int : Integer){
  println(int)
}
  3. Functions that returns a value but takes no parameter
    fun getAuthorsName() : String {
 return "Olorunleke Opeyemi"
}

fun getTodaysDate() : Date {
  return Date()
}
  4. Functions that accept a value and returns a value
    class Example{
 fun main(args: Array<String>) {
   println(evaluateInteger(21, 23))
 }
  fun evaluateInteger (a : Int, b: Int) : String {
   return if (a>b) {
           "$a is greater than $b"
        } else if (a<b){
           "$b is greater than $a"
        } else {"they are equal"}
    }
}

Kotlin Class Examples

Class without a Constructor but with default variable (or properties or data) [box type="info" align="" class="" width=""]In class-based object-oriented programming, a constructor is a special type of subroutine called to create an object. It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables.[/box] class Person { val name : String = "Peter" // Default Variable var age : Int = 30 // Default Variable } fun main (args: Array<String>){ val person = Person() // this line tell kotlin to instantiate a new object from 'Person' class person.age = 33 //accessing our 'Person' property person.name = "Peterr"// this won't compile and can't be re-assigned because 'val' keyword makes it immutable } Class without a Constructor but with properties (or variables or data) and Methods fun main (args: Array<S...

Android Clipboard Listener - How to Know when User copies a text in Android

-
Hey, so you want to let your app listen to Clipboard data? Android does not support listening to Clipboard changes with Broadcast Receiver, obviously due to security reasons - evil apps can't listen when you copy sensitive info, such as password, credit card info etc without the doing the extra work of implementing it themselves. However, there's a work-around by listening to when a new Clip Data is added to ClipBoard Manager. In the example below, your app will be able to listen to copied texts

Kotlin Basics - Variables, Basic Types, and Array

-
1. Variables In Kotlin, we use " val"  to declare a constant or " var " keywords to declare a variable. You can specify a type such as String or Int after the variable name. In the example below, we declared a constant firstName of type String with the val keyword. val firstName: String = "Opeyemi" // this is similar to -> final String firstName = "Opeyemi" <- Java But you'll soon realize that in Kotlin , it's often possible to omit the type from the declaration and the compiler won't complain. val lastName = "Olorunleke" // will still compile In the code above, you'll observe that we did not explicitly state the type String. The code above will still work because the compiler has implicitly inferred the type using type inference. We'll come back to this! The difference between the val and var keywords is that the former is immutable ((its value cannot be changed or read-only), while the latter is mu...
