android – 将导航栏放在状态栏下

这是我使用/写的代码.

XML DrawerLayout：

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <include layout="@layout/toolbar" />

    </FrameLayout>

    <com.andrewq.planets.util.ScrimInsetsFrameLayout
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/linearLayout"
        android:layout_width="304dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:insetForeground="#4000">

        <ListView
            android:id="@+id/left_drawer"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice" />
    </com.andrewq.planets.util.ScrimInsetsFrameLayout>

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.
