google-sdk-动态更新手机主题（简单版）

参照google sdk 实例开发的例子：样例中有些勘误

MainActivity.java的代码：

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       
        setTheme(R.style.Theme_Transparent);
        setTheme(R.style.Theme_Translucent2);
        setTheme(R.style.Theme_Translucent);
        setContentView(R.layout.activity_main);
    }

styles.xml中添加style的样例：

<style name="Theme_Translucent">
          <item name="android:windowBackground">@drawable/pink</item>
        <item name ="android:windowNoTitle">false</item>
        <item name = "android:colorForeground">@drawable/blue</item>
        <item name = "android:colorBackground">@drawable/white</item>
    </style>
    <style name="Theme_Translucent2" >
              <item name="android:windowBackground">@drawable/white</item>
        <item name ="android:windowNoTitle">false</item>
        <item name = "android:colorForeground">@drawable/darkgreen</item>
        <item name = "android:colorBackground">@drawable/pink</item>
    </style>
    <style name="Theme_Transparent">
          <item name="android:windowBackground">@drawable/darkgreen</item>
        <item name ="android:windowNoTitle">true</item>
        <item name = "android:colorForeground">@drawable/blue</item>
        <item name = "android:colorBackground">@drawable/pink</item>
    </style>

dimens.xml中添加颜色类型：

<drawable name="blue">#ff0000ff</drawable>
    <drawable name="pink">#ff00ffff</drawable>
    <drawable name="white">#ffffffff</drawable>
   <drawable name="darkgreen">#ff00ff00</drawable>
