In the previous post, we made a HelloWorld program in Kotlin, that was quite simple but today we will see how to make a simple method or function in Kotlin.
Basically, the declaration of function starts with a fun keyword. The simple syntax of function will look like below:-
fun addMethod(){
}
Kotlin takes a return type of a method in a simple manner like:-
fun addMethod():Int{
}
Now let us see a simple code that explains the creation of a simple method in kotlin.
package adapter.manasvi.com.simpleproject
import android.app.Application
import android.content.Context
import android.os.Bundle
import android.util.Log
import android.widget.TextView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import kotlinx.android.synthetic.main.activity_main.*
class HelloWorld : AppCompatActivity() {
val str:String=”Hello World”
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
someMethod()
}
fun someMethod() {
textView.text=str
}
}
Feel free to read and try the above example.
