</PreferenceScreen>

然后在Activity中显示首先要继承PreferenceActivity而不是继承Activity

public class PreFerenceDemo extends PreferenceActivity {

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.addPreferencesFromResource(R.xml.preference);

//标题

PreFerenceDemo.this.setTitle("系统设置");
        mContext=this;
        
        //页面设置

//加载实例化
         set_font=(ListPreference)findPreference("set_font");
         set_ge=(ListPreference)findPreference("set_ge");
         set_image=(ListPreference)findPreference("set_image");
        //网络设置
         set_user=(ListPreference)findPreference("set_user");
         set_server=(ListPreference)findPreference("set_server");

//设置点击事件

       set_yudu.setOnPreferenceClickListener(new onPreferenceClickListenerYudu());
        set_yudu.setOnPreferenceChangeListener(new onPreferenceChangeListenerChangeYudu());
        set_accept.setOnPreferenceClickListener(new onPreferenceClickListenerAccept());

 private class onPreferenceClickListenerYudu implements OnPreferenceClickListener{

        public boolean onPreferenceClick(Preference preference) {
            // TODO Auto-generated method stub
            return false;
        }
        
    }
    
    private class onPreferenceChangeListenerChangeYudu implements OnPreferenceChangeListener{

        public boolean onPreferenceChange(Preference preference, Object newValue) {
            // TODO Auto-generated method stub
            return false;
        }
        
    }
