SharedPreferences 

能存储一下类型数据

• Boolean
• Float
• Int
• Long
• String
• String Set

A few of the most common preferences are:

CheckBoxPreference

Shows an item with a checkbox for a setting that is either enabled or disabled. The saved value is a boolean (true if it's checked).

ListPreference

Opens a dialog with a list of radio buttons. The saved value can be any one of the supported value types (listed above).

EditTextPreference

Opens a dialog with an EditText widget. The saved value is a String.

 

要想每组有个分割线 就把子元素放到这个标签下面

<PreferenceCategory

监控配置变化的状态。注意的是貌似在onPreferenceChange执行结束之后才会修改sharePreference文件。返回值如果设置false的时候，checkbox不会修改！

public class SettingActivity extends PreferenceActivity  implements OnPreferenceChangeListener {@Overridepublic boolean onPreferenceChange(Preference preference, Object newValue) {System.out.println("preference:"+preference.getKey()+"  "+newValue);// TODO Auto-generated method stubSharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);// System.out.println(prefs.getBoolean("开启声音", true));return true;}
}

自定义带图片PreferenceActivity

自定义一个Perference

public class ImagePreference extends Preference {private ImageView iv_perference_icon;private int _id;private OnClickListener mOnClickListener;public ImagePreference(Context context,int id) {super(context);this._id = id;//设置布局文件setLayoutResource(R.layout.preference_list_item_layout);}
//重绘@Overrideprotected void onBindView(View view) {super.onBindView(view);iv_perference_icon = (ImageView) view.findViewById(R.id.iv_perference_icon);iv_perference_icon.setImageResource(_id);view.setClickable(true);view.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View view) {if(mOnClickListener!=null)mOnClickListener.onClick(view);else return;}});}public void setOnClickListener(OnClickListener mOnClickListener){this.mOnClickListener = mOnClickListener;}}

PreferenceActivity会自动帮你保存配置值到 SharePreference中，下一次启动的时候，会自动帮你显示已经更改的状况。   使用如下方法读取当前文件中保存的值

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);// System.out.println(prefs.getBoolean("开启声音", true));
