本文实例为大家分享了Android实现数独游戏的具体代码，供大家参考，具体内容如下

1、在src中有4个Java类：

其中代码分别是：

Game.java:

package com.example.test1;

import android.R.integer;

public class Game {

public final String str="360000000004230800000004200"

/*public final String str="124576893"+"967348521"+"835291674"+

"259784316"+"316952748"+"748613902"+"582439160"+"493167285"+"671825430";*/

MainActivity.java:

package com.example.test1;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

ShuduView sView=new ShuduView(this);

setContentView(sView);

//setContentView(R.layout.activity_main);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}

2、布局Layout中的配置文件：

其中activity_main.xml:

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context=".MainActivity" >

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/hello_world" />

dialog.xml:

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical" >

android:id="@+id/usedTextId"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/hello_world"

/>

keypad.xml:

xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/keypad"

android:orientation="vertical"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:stretchColumns="*">

android:text="1"/>

android:text="2"/>

android:text="3"/>

android:text="4"/>

android:text="5"/>

android:text="6"/>

android:text="7"/>

android:text="8"/>

android:text="9"/>

3、values中的配置文件

就只有color.xml是自己写的，另外三个都是自动生成

color.xml

#ffe6f0ff

#64ff0000

#64ffffff

#6400ff00

4、一切就绪直接运行就0k
