android PreferenceFragment

初始化：

 public SettingPreferenceFragment() {
 }

 public void setArguments(Bundle bundle){
        String targetId = bundle.getString("targetId");
 }

初始化控件：

1、xml 放到 res下的xml文件夹：

 <?xml version="1.0" encoding="utf-8"?>
 <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

     <com.thejoyrun.crew.rong.widget.FontSizeSwitchPreferenceCompat
         android:key="pref_message_top"
         android:title="top"/>

     <com.thejoyrun.crew.rong.widget.FontSizeSwitchPreferenceCompat
         android:key="pref_message_notice"
         android:title="notice"/>

 </PreferenceScreen>

2、查找控件

  @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         addPreferencesFromResource(R.xml.setting);

         pref_message_top = ((SwitchPreference) findPreference("pref_message_top"));
         pref_message_notice = ((SwitchPreference) findPreference("pref_message_notice"));
 }

控件切换事件：

 @Override
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        String key = preference.getKey();
        final boolean result = (boolean) newValue;

        if (key.equals("pref_message_top")) {
        }
        return true;
}    

控件点击事件：

 　　@Override
     public boolean onPreferenceClick(Preference preference) {
         return true;
     }
