Text View

• textView is object variable which was Created from TextView class , later it was connected to id of TextView from xml ,named text_view_id on activity class.

• .text method work as getText() / setText() method from java
• if .text method is left side of = operator than it will work as setText()
• and if .text is on right side that it will work as getText() but it return Editable! format , so we need to convert it to string with .toString() method

• textView.text = “$message” is used to set message in String format to display

package myfirstkotlinapp
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.TextView

class MainActivity : AppCompatActivity() {


// Declare variable of TextView Type
			lateinit var textView : TextView

		override fun onCreate(savedInstanceState: Bundle?) {	
			super.onCreate(savedInstanceState)
			setContentView(R.layout.activity_main)

			//accessing our textview from layout
			textView = findViewById(R.id.text_view_id) 

			// assign string to text view 
			textView.text = "Enter your Number : "

			// get string from textView 
			val msg : String = textView.text.toString()
}
