1、在src中有4个Java类：
其中代码分别是：
Game.java:

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);

//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>
