 复制代码 2.然后在preferenceActivity里面引用就好了 
1. import android.app.Activity;
2. import android.os.Bundle;
3. import android.preference.CheckBoxPreference;
4. import android.preference.Preference;
5. import android.preference.Preference.OnPreferenceChangeListener;
6. import android.preference.PreferenceActivity;
7. 
8. public class preferenceScreen extends PreferenceActivity
9. {
10. private CheckBoxPreference chekcb=null;
11. /** Called when the activity is first created. */
12. @Override
13. protected void onCreate(Bundle savedInstanceState) {
14. // TODO Auto-generated method stub
15. super.onCreate(savedInstanceState);
16. addPreferencesFromResource(R.xml.preference);
17. chekcb=(CheckBoxPreference) findPreference("autoBack");//这里就像findViewById一样,不过这里的id其实是key的值..
18. 
19. //下面设置监听器
20. chekcb.setOnPreferenceChangeListener(new myPreferencesChance());
21. }
22. class myPreferencesChance implements OnPreferenceChangeListener{
23. 
24. @Override
25. public boolean onPreferenceChange(Preference preference, Object newValue) {
26. // TODO Auto-generated method stubd
27. System.out.println("newValue"+newValue);
28. return true;
29. }
30. 
31. }
32. }

 有时候因为需要我们需要自己定义个preference选项..系统自带的那些就满足不了我们了..下面让我们来看下如何自定义preference选项,其实很简单..比如说你要定义一个对话框形式的preference..只要继承DialogPreference就可以了,然后在preferenceScreen里面引用,设置一下属性就好了,xml设置,请看上面的preferenceScreen.xml文件..下面是代码 
1. ackage preferenceScreen.hall;
2. 
3. import android.content.Context;
4. import android.preference.DialogPreference;
5. import android.util.AttributeSet;
6. import android.widget.SeekBar;
7. import android.widget.SeekBar.OnSeekBarChangeListener;
8. 
9. public class SeekBarPreference extends DialogPreference implements OnSeekBarChangeListener{
10. 
11. public SeekBarPreference(Context context, AttributeSet attrs) {
12. super(context, attrs);
13. // TODO Auto-generated constructor stub
14. }
15. @Override
16. public void onProgressChanged(SeekBar seekBar, int progress,
17. boolean fromUser) {
18. // TODO Auto-generated method stub
19. 
20. }
21. 
22. @Override
23. public void onStartTrackingTouch(SeekBar seekBar) {
24. // TODO Auto-generated method stub
25. 
26. }
27. 
28. @Override
29. public void onStopTrackingTouch(SeekBar seekBar) {
30. // TODO Auto-generated method stub
31. 
32. }
33. 
34. }
