Android - How To Get Text From Edittext And Calculate Them?

I have an app, and I want to calculate the edit text. I have this code: package com.minimale.cijfer; import android.app.Activity; import android.os.Bundle; import android.text

Solution 1:

use

Double.valueOf(String s);

instead of

Double.parseDouble();

and also replace

finalResult.setText(answer + "");

with

finalResult.setText(Double.toString(answer) + "");
