Reset code for EditText and TextView for android

Question

I'm new in programming. I did a simple android app which ask user to put 2 numbers, do calculations, display the answer by clicking calculate button. Now I'm trying to set up reset button to clear all the fields. Checked for the solution on stack overflow, but still cannot figure out how to do it. This is my code:

 public void calculate(View view)
 {

    EditText number1 = (EditText)findViewById(R.id.num1ID);
    EditText number2 = (EditText)findViewById(R.id.num2ID);

    Double num1Value = Double.parseDouble(number1.getText().toString());
    Double num2Value = Double.parseDouble(number2.getText().toString());

    Double resultValue = num1Value - num2Value;
    TextView resultDisplay = (TextView)findViewById(R.id.resultID);

    resultDisplay.setText(Double.toString(resultValue));
    }

Thank you.

Answer 1

Just add button resetButton to layout

Button resetButton = (Button) findViewById(R.id.btnReset); 
    resetButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            number1.setText("");
            number2.setText("");
            resultDisplay.setText("");
        }
    });

Answer 2

Have a method like this

public void resetTextViews() {
      number1.setText("");
      number2.setText("");
      resultDisplay.setText("");
}

Then just set an on click listener on your button that calls that method.
