How can I show addition of two variables and also a text in TextView

Question

I have two variables. I need to show these variables addition and also add some text in textView.

Example

val a val b

The text i needed "Addition is (a+b)"

Sorry if i've done any mistake, I'm a newbie.

Answer 1

val a =...
val b =...

val textView =...

In Kotlin you can use interpolation so

textView.text = "Addition is ($a+$b)"

the Android way of doing so is using the strings.xml

<string name="addition">Addition is (%1d+%2d)</string>

And then

textView.text = resources.getString(R.string.addition, a, b)

Answer 2

    int c=a+b;
     
    String textNeeded="Addition is "+c;

    textView.setText(textNeeded);
