android – 将导航栏放在状态栏下

我试图让我的导航栏进入状态栏.我已经广泛阅读了关于ScrimInsetsFrameLayout视图,我尝试实现它,但由于某种原因,它不会被忽略.

这是我使用/写的代码.

XML DrawerLayout：

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    xmlns:android="http://scheR_817_11845@as.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://scheR_817_11845@as.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>


</android.support.v4.widget.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.

<style name="YourTheme.TranslucentStatus" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowTranslucentStatus">true</item>
</style>

if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
    //enable translucent statusbar via flags
    setTranslucentStatusFlag(true);
}
if (Build.VERSION.SDK_INT >= 19) {
    mActivity.getWindow().getDecorView().setsystemUIVisibility(View.SYstem_UI_FLAG_LAYOUT_STABLE | View.SYstem_UI_FLAG_LAYOUT_FULLSCREEN);
}
if (Build.VERSION.SDK_INT >= 21) {
    //we don't need the translucent flag this is handled by the theme
    setTranslucentStatusFlag(false);
    //set the statusbarcolor transparent to remove the black shadow
    mActivity.getWindow().setStatusBarColor(Color.TRANSPARENT);
}

//add a padding to the content of the drawer (25dp on devices starTing with api v19)
mDrawerContentRoot.setPadding(0,mActivity.getresources().getDimensionPixelSize(R.dimen.tool_bar_top_padding),0);

// define the statusBarColor
mDrawerContentRoot.seTinsetForeground(R_817_11845@StatusBarColor);


private void setTranslucentStatusFlag(Boolean on) {
    if (Build.VERSION.SDK_INT >= 19) {
        Window win = mActivity.getWindow();
        WindowManager.LayoutParams winParams = win.getAttributes();
        final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
        if (on) {
            winParams.flags |= bits;
        } else {
            winParams.flags &= ~bits;
        }
        win.setAttributes(winParams);
    }
}
