基于Android实现数独游戏

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" 
          +"070460003820000014500013020" 
          +"001900000007048300000000045"; 
  /*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);

  } 
 
 
  @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:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  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" > 
 
  <TextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@string/hello_world" /> 
 
</RelativeLayout> 

dialog.xml:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:orientation="vertical" > 
   
  <TextView  
    android:id="@+id/usedTextId" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello_world" 
    /> 
 
</LinearLayout> 

keypad.xml:

<?xml version="1.0" encoding="utf-8"?> 
<!-- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  android:orientation="vertical" > 
   
 
   
</LinearLayout> --> 
 
<TableLayout 
  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="*"> 
  <TableRow> 
    <Button android:id="@+id/keypad_1" 
      android:text="1"/> 
    <Button android:id="@+id/keypad_2" 
      android:text="2"/> 
    <Button android:id="@+id/keypad_3" 
      android:text="3"/> 
  </TableRow> 
    <TableRow> 
    <Button android:id="@+id/keypad_4" 
      android:text="4"/> 
    <Button android:id="@+id/keypad_5" 
      android:text="5"/> 
    <Button android:id="@+id/keypad_6" 
      android:text="6"/> 
  </TableRow> 
    <TableRow> 
    <Button android:id="@+id/keypad_7" 
      android:text="7"/> 
    <Button android:id="@+id/keypad_8" 
      android:text="8"/> 
    <Button android:id="@+id/keypad_9" 
      android:text="9"/> 
  </TableRow> 
</TableLayout> 

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

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <color name="shudu_background">#ffe6f0ff</color> 
  <color name="shudu_dark">#64ff0000</color> 
  <color name="shudu_light">#64ffffff</color> 
  <color name="shudu_hilite">#6400ff00</color> 
</resources>
