安卓手机开发学习之设置Settings

1.在目录res/xml下新建文件perferences.xml(切记小写开头),在strings配置文件中给变量赋值：

<string name="pref_sync">pref_sync</string>
    <string name="pref_sync_summ">pref_sync_summ</string>
    <string name="pref_syncConnectionType">pref_syncConnectionType</string>
    <string name="pref_syncConnectionTypes_default">pref_syncConnectionTypes_default</string>
<string-array name="pref_syncConnectionTypes_entries">
   <item>长沙</item>
   <item>岳阳</item>
   <item>株洲</item>
   <item>湘潭</item>
   </string-array>
   
<string-array name="pref_syncConnectionTypes_values">
</string-array>

2.让原来继承ActionBarActivity的类继承PreferenceActivity,

3.super.OnCreate语句下面增加addPreferencesFromResource(R.xml.preferences);

4.屏蔽SetContentView
