开发中颜色、样式、数组等等的一些简单定义
Button按下后改变背景：

  <?xml version="1.0" encoding="utf-8" ?> - <selector xmlns:android="http://schemas.android.com/apk/res/android">- <!--  初始状态   -->   <item android:state_pressed="false" android:drawable="@drawable/back_to_previous" /> - <!--  按下状态   -->   <item android:state_pressed="true" android:drawable="@drawable/back_to_previous_press" />   </selector>

定义圆角背景：

<?xml version="1.0" encoding="UTF-8"?><shape  xmlns:android="http://schemas.android.com/apk/res/android">    <gradient     android:startColor="#ffffffff"     android:endColor="#ffffffff"     android:angle="0.0" />    <corners     android:topLeftRadius="10.0dip"     android:topRightRadius="10.0dip"     android:bottomLeftRadius="10.0dip"     android:bottomRightRadius="10.0dip" /></shape>

颜色的定义 ：
res\values\color.xml

  <?xml version="1.0" encoding="utf-8" ?> - <resources>  <drawable name="red">#D10A27</drawable>   <drawable name="white">#FFFFFF</drawable>   <drawable name="gray">#eff0f3</drawable>   <color name="lightgray">#EAEAEA</color>   <color name="borderColor">#ABABAB</color>   <color name="no_back">#00000000</color>   </resources>

一些控件样式的定义： res\values\styles.xml

<?xml version="1.0" encoding="UTF-8" ?> - <resources>- <!--  动画   --> - <style name="AnimationPreview">  <item name="android:windowEnterAnimation">@anim/push_up_in</item>   <item name="android:windowExitAnimation">@anim/slide_down_out</item>   </style>- <!--  主要的TabActivity   --> - <style name="main_tab_bottom_sys">  <item name="android:textSize">@dimen/bottom_tab_font_size</item>   <item name="android:textColor">#ffffffff</item>   <item name="android:ellipsize">marquee</item>   <item name="android:gravity">center_horizontal</item>   <item name="android:paddingTop">@dimen/bottom_tab_padding_up</item>   <item name="android:paddingLeft">3dip</item>   <item name="android:layout_width">fill_parent</item>   <item name="android:layout_height">wrap_content</item>   <item name="android:button">@null</item>   <item name="android:singleLine">true</item>   <item name="android:drawablePadding">@dimen/bottom_tab_padding_drawable</item>   <item name="android:layout_weight">1.0</item>   </style> </resources>

自定义一个dimens.xml文件，里面存放一些属性，放在values文件夹下，方便修改：
res\values\dimens.xml

<?xml version="1.0" encoding="UTF-8" ?> - <resources>  <dimen name="button_height">45.0dip</dimen>   <dimen name="bottom_tab_font_size">9.0dip</dimen>   <dimen name="bottom_tab_padding_up">32.0dip</dimen>   <dimen name="bottom_tab_padding_drawable">2.0dip</dimen>   <dimen name="switch_logo_bottom_padding">30.0sp</dimen>   <dimen name="widget_height">100.0dip</dimen>   <dimen name="sta_height">48.0dip</dimen>   <dimen name="widget_write_margin_top">19.0dip</dimen>   <dimen name="widget_write_margin_left">10.0dip</dimen> </resources>

自定义一个arrays.xml文件，放在values文件夹下，用来存放一些数组,方便使用时候取得；

<?xml version="1.0" encoding="UTF-8"?><resources><string-array name="main_munu_name">        <item>机票查询</item>        <item>酒店查询</item>        <item>航班动态</item>        <item>酒店点评</item>        <item>登录注册</item>        <item>我的携程</item>        <item>收藏夹</item>        <item>问题反馈</item>        <item>设置</item>    </string-array></resources>

工程中出现的所有String类型的汉字都放在strings.xml下面，方便修改：

<?xml version="1.0" encoding="UTF-8"?><resources><string name="app_name">携程无线</string>    <string name="app_name_en">Ctrip</string>    <string name="system_init">系统初始化...</string>    <string name="title_notice">最新公告</string>    <string name="title_order">填写订单</string>    <string name="filght_inquire">机票查询</string>    <string name="title_filght_list">选择航班</string>    <string name="title_filght_detail">航班详情</string></resources>
