上一篇讲述了PreferenceFragment中的各种控件，接下来为各个控件添加监听事件。。。。

主要实现了3个接口OnPreferenceClickListener，OnSharedPreferenceChangeListener和OnPreferenceChangeListener。

onPreferenceClick为点击事件，当点击Preference控件后将触发该方法。但是EditTextPreference等修改内容后再次确认时，不会调用该方法。为了解决这一问题，onSharedPreferenceChanged登场了。当Preference控件内容发生改变时，将触发该方法。最后onPreferenceChange方法用于MultiSelectList和Ringtone的调用。

细节就直接上代码啦，这样比较清楚。。。

public class SettingFragment extends PreferenceFragment implements Preference.OnPreferenceClickListener, SharedPreferences.OnSharedPreferenceChangeListener,Preference.OnPreferenceChangeListener {private CheckBoxPreference checkbox;private EditTextPreference edittext;private MultiSelectListPreference MultiSelectList;private ListPreference list;private RingtonePreference Ringtone;private SwitchPreference Switch;private Preference preference;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);addPreferencesFromResource(R.xml.setting);//根据key值找到控件checkbox = (CheckBoxPreference) findPreference("checkbox");edittext = (EditTextPreference) findPreference("edittext");MultiSelectList = (MultiSelectListPreference)findPreference("MultiSelectList");list = (ListPreference)findPreference("list");Ringtone = (RingtonePreference) findPreference("Ringtone");Switch = (SwitchPreference) findPreference("switch");// 设置监听器checkbox.setOnPreferenceClickListener(this);edittext.setOnPreferenceClickListener(this);Ringtone.setOnPreferenceClickListener(this);MultiSelectList.setOnPreferenceChangeListener(this);Ringtone.setOnPreferenceChangeListener(this);// 得到我们的存储Preferences值的对象，然后对其进行相应操作SharedPreferences shp = PreferenceManager.getDefaultSharedPreferences(this.getActivity());boolean apply_Checked = shp.getBoolean("checkbox", false);//获取历史设置SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this.getActivity());edittext.setSummary(sp.getString("edittext", ""));}@Override// 点击事件触发public boolean onPreferenceClick(Preference preference) {// 对控件进行操作if (preference == checkbox) {Toast.makeText(this.getActivity(), " 点击了checkbox :" + checkbox.isChecked(), Toast.LENGTH_SHORT).show();} else if (preference == edittext) {edittext.setText("");Toast.makeText(this.getActivity(), " 点击了edittext :" + edittext.getText(), Toast.LENGTH_SHORT).show();} else if (preference == Ringtone) {Toast.makeText(this.getActivity(), " 点击了Ringtone :" + Ringtone.getRingtoneType(), Toast.LENGTH_SHORT).show();}return true;}//当Preference发生变化时调用@Overridepublic void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {if (key.equals("edittext")) {edittext.setSummary(edittext.getText());}if (key.equals("list")) {list.setSummary(list.getValue());}if(key.equals("Ringtone")){Ringtone.setSummary(Ringtone.getRingtoneType());}if(key.equals("switch")){Switch.setSummary(String.valueOf(Switch.isChecked()));}}@Overridepublic void onResume() {super.onResume();//注册事件getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);}@Overridepublic void onPause() {//注销事件getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);super.onPause();}@Overridepublic boolean onPreferenceChange(Preference preference, Object newValue) {if (preference == MultiSelectList) {MultiSelectList.setSummary(newValue.toString());return true;}if (preference == Ringtone) {Ringtone.setSummary(newValue.toString());return true;}return false;}
}
