editText get text kotlin

Question

How to get editText in kotlin and display with toast.

var editTextHello = findViewById(R.id.editTextHello)

I tried this but shows object

Toast.makeText(this,editTextHello.toString(),Toast.LENGTH_SHORT).show()

Answer 1

To maintain the standard syntax of Kotlin use

var editText: EditText = findViewById(R.id.editTextHello)

Answer 2

In Kotlin calling .text on your EditText is fine no need to do getText or toString

Toast.makeText(this, editTextHello.text, Toast.LENGTH_SHORT).show()

with button click

button?.setOnClickListener {
        Toast.makeText(this,editText.text, Toast.LENGTH_LONG).show()
    }

Even don't need findViewById

Answer 3

This is Kotlin, not java. You do not need to get the id of it. In kotlin, just write:

var editTextHello = editTextHello.text.toString()

use the beauty of kotlin ;-)

P.s: BTW, better to choose xml IDs like edx_hello and for the kotlin part, var editTextHello. Then you can differentiate between xml vars and kotlin vars.

Answer 4

use editTextHello.text

  Toast.makeText(this, editTextHello.text, Toast.LENGTH_SHORT).show()

Answer 5

Use this instead it's working fine

val obj=findViewById<EditText>(R.id.editText)
Toast.makeText(this,obj.text, Toast.LENGTH_LONG).show()

Answer 6

Toast.makeText(this, editTextHello.text.toString(), Toast.LENGTH_SHORT).show()

If you make edittext as nullable then the line would be

Toast.makeText(this, editTextHello?.text.toString(), Toast.LENGTH_SHORT).show()
