res/values目录常用xml文件

提示：获取Resources 

 Resources Resources = getBaseContext().getResources();

 

一、strings.xml代码 

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <string name="hello">Hello World, Main!</string>
 </resources>

获取代码: 

 String app_name = getResources().getString(R.string.app_name);

 

二、arrays.xml代码 

 

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <array
         name="items">
         <item>中国</item>
         <item>日本</item>
         <item>韩国</item>
     </array>
     <integer-array
         name="moneys">
         <item>100</item>
         <item>200</item>
         <item>300</item>
         <item>400</item>
         <item>500</item>
     </integer-array>
     <string-array
         name="levels">
         <item>一等级</item>
         <item>二等级</item>
         <item>三等级</item>
     </string-array>
 </resources>

 

获取代码： 

 String items[] = getResources().getStringArray(R.array.level);
 int int_array[] = getResources().getIntArray(R.array.moneys);

 

三、colors.xml代码 

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <color name="white">#ffffff</color>
     <color name="black">#000000</color>
     <color name="grey">#333333</color>
     <color name="yellow">#fccf29</color>
 </resources>

 

获取代码： 

 int color = getResources().getColor(R.color.yellow);
 textView1.setTextColor(color);
 //或者写成textView1.setTextColor(Color.YELLOW);

 

四、styles.xml代码 

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <style name="titleText">
         <item name="android:textSize">18px</item>
         <item name="android:textColor">#213255</item>
         <item name="android:background">#888888</item>
     </style>
 </resources>

 

获取代码(xml)： 

 style="@style/titleText"

 

五、dimens.xml代码 

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
     <dimen name="big_font">30px</dimen>
     <dimen name="middle_font">20px</dimen>
     <dimen name="small_font">10px</dimen>
 </resources>

 

获取代码： 

 float dimens = getResources().getDimension(R.dimen.big_font);
 xml_dimens.setTextSize(dimens);
