EditTextPreference 小标题修改为显示内容

应用EditTextPreference进行系统配置，感觉EditTextPreference只显示大小标题，点击修改才能看到值，不够简单明了。

想要实现小标题显示内容效果：

功能实现：

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="服务器IP地址设置"  
        android:summary="点击输入"  
        android:dialogTitle="输入IP地址"  
        android:defaultValue="10.10.10.10"/>  
        
    </PreferenceCategory>
     <PreferenceCategory android:title="@string/updateset">
         <CheckBoxPreference android:title="@string/autoupdate"/>   
     
    </PreferenceCategory>
</PreferenceScreen>
