以下都是基於Android 6.0 的程式碼去修改的！！！

十四、將桌面workspace、hotseat 大小調整 放大一半 ，

這個要根據自己的需求來制定

 workspace.setPadding(padding.left/2, padding.top/2, padding.right/2, padding.bottom);

 hotseat.setPadding(edgeMarginPx + padding.left/2, 0,
                    edgeMarginPx + padding.right/2,
                    2 * edgeMarginPx);

十三、隱藏Launcher3 桌面介面 上面的 搜尋欄 

packages\apps\Launcher3\src\com\android\launcher3\Launcher.Java

 //mSearchDropTargetBar.addView(mQsb); 註釋掉這一行 就行

十二、修改Launcher3 appall app選單列表背景透明度

\packages\apps\Launcher3\src\com\android\launcher3\allapps\AllAppsContainerView.java

        mContainerView.setBackground(background);

        //mRevealView.setBackground(background.getConstantState().newDrawable());
        mAppsRecyclerView.updateBackgroundPadding(bgPadding);
        mAdapter.updateBackgroundPadding(bgPadding);
mContainerView.getBackground().setAlpha(20);

packages\apps\Launcher3\src\com\android\launcher3\op09\AllAppsContainerView.java

        mContainerView.setBackground(null);
        //mRevealView.setBackground(background.getConstantState().newDrawable());

十一、長按電源鍵 只顯示 關機 一項

我們知道長按Power鍵會彈出選項，如 關機、 重啟、飛航模式。現在想只保留一項  關機 ；

frameworks/base/core/res/res/values/config.xml

搜尋 config_globalActionsList 

    <string-array translatable="false" name="config_globalActionsList">
        <item>power</item>

    </string-array>

以下是參考 ，需要新增的放在上面這個數組裡面就是了  ：

<item>power</item>關機選項
<item>bugreport</item>錯誤報告選項
<item>airplane</item>飛航模式選項
<item>silent</item>靜音振動鈴聲選項
<item>restart</item>重啟選項

<item>reboot</item>//新增重啟功能   <item>settings</item>設定選項
<item>lockdown</item>鎖屏選項
<item>screencapture</item>截圖、錄製選項
<item>users</item>使用者選項

十、無法寫入sn號，需要把這個 巨集 開啟,這個去掉註釋,讓寫的barcode生效,barcode就是SN,不然都是預設的123456789ABCDEF

vendor/mediatek/proprietary/bootable/bootloader/lk/app/mt_boot/mt_boot.c

九、launcher  focus_indicator 桌面 頁面 顯示錶示 （就是桌面上那小白點），在設定系統字型大小後和在app_app介面螢幕旋轉 回到all_app 介面會顯示出來 ，bug，讓它不顯示：

  通話介面 為避免 臉部貼近螢幕 而 設計 黑屏 ，是最好的列子。
