어릴때 많이 가지고 놀던 숫자 퍼즐게임인데...

인터넷 돌아다니다 우현히 보게되서...

어떻게 만들었을까 고민 시작 하기도 전에 코딩해봤습니다...

안드로이드에서 기본 제공하는 버튼과 기본 레이아웃을 사용. 소스는 아래와 같습니다.

gradientbox3.xml (버튼 그라디언트 주기위해)

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
   
    <corners android:radius="20dp"/>
   
    <gradient
        android:startColor="#FFAAAAFF"
        android:endColor="#FFffffff"
        android:angle="90" />
   
    <padding
     android:left="5dp"
     android:top="5dp"
     android:right="5dp"
     android:bottom="5dp" />
   
    <stroke
        android:width="4dp"
        android:color="#99232323" />
   
</shape>

다음은 기본으로 생성되는 엑티비디에 전체 소스를 쑤셔 넣었어요.......

위소스를 실행한 화면은 아래와 같습니다...

기획도 없고, 설계도 없고, 머리에 그려지는 대로 코딩해서, 주석도 없습니다.
