EditTextPreference 小標題修改爲顯示內容

應用EditTextPreference進行系統配置，感覺EditTextPreference只顯示大小標題，點擊修改才能看到值，不夠簡單明瞭。

想要實現小標題顯示內容效果：

功能實現：

public class SysCfg extends PreferenceActivity {
	@SuppressWarnings("deprecation")
	@Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        this.addPreferencesFromResource(R.xml.syscfg);  
        
        final EditTextPreference serverip = (EditTextPreference)findPreference("ServerIP");
        SharedPreferences shp = PreferenceManager.getDefaultSharedPreferences(this);
        serverip.setSummary(shp.getString("ServerIP", "12.12.12.12"));        
        
        serverip.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
			
			@Override
			public boolean onPreferenceChange(Preference preference, Object newValue) {
				// TODO Auto-generated method stub
				serverip.setSummary(newValue.toString());
				serverip.setDefaultValue(newValue);
				
				return true;
			}
		});
        
    }
	
}

XML

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
    <PreferenceCategory android:title="@string/IPaddress">
	    <EditTextPreference  
		android:key="ServerIP"  
		android:title="服務器IP地址設置"  
		android:summary="點擊輸入"  
		android:dialogTitle="輸入IP地址"  
		android:defaultValue="10.10.10.10"/>  
		
	</PreferenceCategory>
	 <PreferenceCategory android:title="@string/updateset">
	 	<CheckBoxPreference android:title="@string/autoupdate"/>

</PreferenceScreen>
