A Simple Android Application For Adding Two Numbers

Hi, I am practising on android app I've made an simple app for adding two number:

Firstly modifying the .xml file in addition/res/layout/main.xml which is responsible for the layout of the application.

<?xml version="1.0" encoding="utf-8"?>
    <AbsoluteLayout android:id="@+id/widget0"
    <TextView android:layout_width="wrap_content"
     android:text="ADDITION OF NUMBERS"
    <TextView android:layout_width="wrap_content"
    android:text="First Amount"
    <EditText android:text=""
    <TextView android:layout_width="wrap_content"
    android:text="Second Amount"
    <EditText android:text=""
    <Button android:layout_width="wrap_content"
    <EditText android:text=""

Now modify the addition/src/com.example.addition/ as shown belowSadcom.example.addition is the package name)

package com.example.addition;


import android.os.Bundle;

import android.widget.EditText;

import android.widget.TextView;

import android.widget.Button;

import android.view.View;

public class test extends Activity
  EditText amount1;
  EditText amount2;
  TextView tt;
  Button calculate;
  double x=0;
  double y=0;
  double z=0;
  /** Called when the activity is first created. */
  public void onCreate(Bundle savedInstanceState)
  private void initControls()
      calculate.setOnClickListener(new Button.OnClickListener()
      {public void onClick
      (View  v) { calculate();}});
  private void calculate()

We are done.Now run the application in the android emulator.
