这是我使用/写的代码.

XML DrawerLayout：

最后,这里是我的styles.xml for values-v21：

<?xml version="1.0" encoding="utf-8"?>
<resources>
 
    <style name="AppThemeNavDrawer" parent="Theme.AppCompat.NoActionBar">
        <item name="colorAccent">#F8F8F8</item>
        <item name="android:windowTranslucentStatus">true</item>
 
        <item name="windowActionBar">false</item>
        <item name="windowActionModeOverlay">true</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

我看过2014年的I / O应用源代码以及this的问题,我不知道有什么不同.

这是一个屏幕截图,我到目前为止减去状态栏下的抽屉：

我有一切工作完美,这是我需要做的最后一件事.帮助非常感谢！

编辑：

为了弄清楚,我想像在大多数Google Apps和Google Now中一样,将状态栏中的图像着色.
