對於2.3的rom而言，應該修改SystemUI.apk
修改過程如下：
1、添加相關圖片。
2、res\layout\文件夾下添加quickpanel_quick_settings.xml文件
3、在res\values\strings.xml裏添加值：
<string name="quickpanel_wifi_text">Wi-Fi</string>
<string name="quickpanel_bluetooth_text">Bluetooth</string>
<string name="quickpanel_gps_text">GPS</string>
<string name="quickpanel_sound_text">Sound</string>
<string name="quickpanel_sound_vibration_text">"SoundVibration"</string>
<string name="quickpanel_silent_text">Silent</string>
<string name="quickpanel_vibration_text">Vibration</string>
<string name="quickpanel_error_text">Error</string>
<string name="quickpanel_data_text">Data</string>
在res\values-zh-rCN\strings.xml裏添加值：
<string name="quickpanel_bluetooth_text">藍牙</string>
<string name="quickpanel_sound_text">聲音</string>
<string name="quickpanel_sound_vibration_text">聲音振動</string>
<string name="quickpanel_silent_text">靜音</string>
<string name="quickpanel_vibration_text">振動</string>
<string name="quickpanel_error_text">錯誤</string>
<string name="quickpanel_data_text">數據</string>
4、在res\values\ids.xml里加入以下代碼：
<item type="id" name="quickpanel_quick_settings">false</item>
<item type="id" name="quickpanel_wifi_btn_icon">false</item>
<item type="id" name="quickpanel_wifi_btn_text">false</item>
<item type="id" name="quickpanel_wifi_btn_status_icon">false</item>
<item type="id" name="quickpanel_bt_btn_icon">false</item>
<item type="id" name="quickpanel_bt_btn_text">false</item>
<item type="id" name="quickpanel_bt_btn_status_icon">false</item>
<item type="id" name="quickpanel_gps_btn_icon">false</item>
<item type="id" name="quickpanel_gps_btn_text">false</item>
<item type="id" name="quickpanel_gps_btn_status_icon">false</item>
<item type="id" name="quickpanel_sound_btn_icon">false</item>
<item type="id" name="quickpanel_sound_btn_text">false</item>
<item type="id" name="quickpanel_sound_btn_status_icon">false</item>
<item type="id" name="quickpanel_data_btn_icon">false</item>
<item type="id" name="quickpanel_data_btn_text">false</item>
<item type="id" name="quickpanel_data_btn_status_icon">false</item>
5、在mali\com\android\systemui\statusbar\文件夾下添加quickpanel文件夾，並修改16進制數值所對應的新id。
6、在smali\com\android\systemui\R$drawable.smali加入：（排序方式爲英語字母）
此處定義的是19個圖標文件
.field public static final quickpanel_icon_bluetooth_ing:I = 0x7f0200e7
.field public static final quickpanel_icon_bluetooth_off:I = 0x7f0200e8
.field public static final quickpanel_icon_bluetooth_on:I = 0x7f0200e9
.field public static final quickpanel_icon_gps_off:I = 0x7f0200ea
.field public static final quickpanel_icon_gps_on:I = 0x7f0200eb
.field public static final quickpanel_icon_ing:I = 0x7f0200ec
.field public static final quickpanel_icon_off:I = 0x7f0200ed
.field public static final quickpanel_icon_on:I = 0x7f0200ee

.field public static final quickpanel_icon_wifi_off:I = 0x7f0200f6
.field public static final quickpanel_icon_wifi_on:I = 0x7f0200f7
.field public static final quickpanel_quick_settings_background:I = 0x7f0200f8
.field public static final quickpanel_title_background:I = 0x7f0200f9
7、smali\com\android\systemui\R$id.smali中加入\res\values\ids.xml中加入的新id
.field public static final quickpanel_quick_settings:I = 0x7f090016
.field public static final quickpanel_wifi_btn_icon:I = 0x7f090017
.field public static final quickpanel_wifi_btn_text:I = 0x7f090018
.field public static final quickpanel_wifi_btn_status_icon:I = 0x7f090019
.field public static final quickpanel_bt_btn_icon:I = 0x7f09001a
.field public static final quickpanel_bt_btn_text:I = 0x7f09001b
.field public static final quickpanel_bt_btn_status_icon:I = 0x7f09001c
.field public static final quickpanel_gps_btn_icon:I = 0x7f09001d
.field public static final quickpanel_gps_btn_text:I = 0x7f09001e
.field public static final quickpanel_gps_btn_status_icon:I = 0x7f09001f
.field public static final quickpanel_sound_btn_icon:I = 0x7f090020
.field public static final quickpanel_sound_btn_text:I = 0x7f09001
.field public static final quickpanel_sound_btn_status_icon:I = 0x7f09002
.field public static final quickpanel_data_btn_icon:I = 0x7f09003
.field public static final quickpanel_data_btn_text:I = 0x7f09004
.field public static final quickpanel_data_btn_status_icon:I = 0x7f09005
7、smali\com\android\systemui\R$layout.smali中加入\res\layout中新加入的quickpanel_quick_settings.xml所對應的16進制id
.field public static final quickpanel_quick_settings:I = 0x7f030006
8、smali\com\android\systemui\R$string.smali中加入\res\values\string.xml中新加入的新id所對應的id值
.field public static final quickpanel_wifi_text:I = 0x7f070010
.field public static final quickpanel_bluetooth_text:I = 0x7f070011
.field public static final quickpanel_gps_text:I = 0x7f070012
.field public static final quickpanel_sound_text:I = 0x7f070013
.field public static final quickpanel_sound_vibration_text:I = 0x7f070014
.field public static final quickpanel_silent_text:I = 0x7f070015
.field public static final quickpanel_vibration_text:I = 0x7f070016
.field public static final quickpanel_error_text:I = 0x7f070017
.field public static final quickpanel_data_text:I = 0x7f070018
9、smali\com\android\systemui\statusbar\StatusBarService.smali中找到如下代碼：
iget-object v6, p0, Lcom/android/systemui/statusbar/StatusBarService;->mBroadcastReceiver:Landroid/content/BroadcastReceiver;
invoke-virtual {p1, v6, v2}, Landroid/content/Context;->registerReceiver(Landroid/content/BroadcastReceiver;Landroid/content/IntentFilter;)Landroid/content/Intent;
.line 327
return-void
.end method
修改爲：
iget-object v6, p0, Lcom/android/systemui/statusbar/StatusBarService;->mBroadcastReceiver:Landroid/content/BroadcastReceiver;
invoke-virtual {p1, v6, v2}, Landroid/content/Context;->registerReceiver(Landroid/content/BroadcastReceiver;Landroid/content/IntentFilter;)Landroid/content/Intent;
const v6, 0x7f030006
const/4 v9, 0x0
invoke-static {p1, v6, v9}, Landroid/view/View;->inflate(Landroid/content/Context;ILandroid/view/ViewGroup;)Landroid/view/View;
move-result-object v5
check-cast v5, Lcom/android/systemui/statusbar/quickpanel/QuickSettingsView;
.local v5, qsv:Lcom/android/systemui/statusbar/quickpanel/QuickSettingsView;
iget-object v6, p0, Lcom/android/systemui/statusbar/StatusBarService;->mExpandedView:Lcom/android/systemui/statusbar/ExpandedView;
const/4 v2, 0x0
invoke-virtual {v6, v5, v2}, Lcom/android/systemui/statusbar/ExpandedView;->addView(Landroid/view/View;I)V
return-void
.end method
上面0x7f030006爲\res\layout\quickpanel_quick_settings.xml所對應的16進制id
如要修改相關透明，也可修改如下代碼：
.local v7, view:Lcom/android/systemui/statusbar/StatusBarView;
new-instance v0, Landroid/view/WindowManager$LayoutParams;
const/4 v1, -0x1
const/16 v3, 0x7d0
const/16 v4, 0x48
const/4 v5, 0x2
改爲：
.local v7, view:Lcom/android/systemui/statusbar/StatusBarView;
new-instance v0, Landroid/view/WindowManager$LayoutParams;
const/4 v1, -0x1
const/16 v3, 0x7d0
const/16 v4, 0x48
const/4 v5, -0x3
這是修改狀態欄背景透明，要修改狀態欄透明的時候這是必改項！
找到：
.line 1207
const/4 v5, 0x2
修改爲：
.line 1207
const/4 v5, -0x3
這是下拉菜單快捷按鈕背景透明。
10、編譯，並解出classes.dex、resources.arsc、quickpanel_quick_settings.xml和相關圖片，放入SystemUI.apk中。
