Setting the text in EditText dynamically on a button click

Question

I have two EditTexts that have two different values and a button, on click of that button, result of the multiplication should be displayed in the third Edit Text.

Code Written for the function on the button click:

public void Multiply (View view)
{
String str1 = ed1.getText().toString();
        String str2 = ed2.getText().toString();

        int num1 = Integer.parseInt(str1);
        int num2 = Integer.parseInt(str2);

        int prod = num1*num2;

        //Toast.makeText(getBaseContext(), "Product is"+(num1*num2),Toast.LENGTH_LONG ).show();

        ed3.setText(prod);

}

You set int value, but Android expext integer == Resource id. So you need to convert prod to String. ed3.setText(String.valueOf(prod)); — Borys

Mistake:

 ed3.setText(prod);

Try:

ed3.setText(String.valueOf(prod));

Use

ed3.setText(String.valueOf(prod));

or

ed3.setText(""+prod);

EditText won't allow integer to go directly in setText. So convert it into string before setting it

Try this

ed3.setText(String.valueOf(prod));

It is displaying some syntax error, asking to insert ')' after the expression.

Hmm.. Wired have you tried this one ed3.setText(String.valueOf(prod));

I have used exactly the same expression, but it is displaying this error.

I'm sharing the whole code with you. Kindly cross-check, I didnt find any braces left unopened. public void Multiply(View view) { String str1 = ed1.getText().toString(); String str2 = ed2.getText().toString(); int num1 = Integer.parseInt(str1); int num2 = Integer.parseInt(str2); int product = num1*num2; ed3.setText(String.valueOf(product)); }

you can simple add ed3.setText(""+prod); as edittext directly not accept the integer value.
