            // TODO Auto-generated method stub
            if(game.setTileIfValid(selectedX,selectedY,tile))
                    invalidate();
            
    

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:

<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>

4、一切就绪直接运行就0k
