What's the difference between bringToFront in Android 4 and Android 5?

I've got this layout with a DrawerLayout and a ScrollView:

Anyone knows why it's look like this in Android 4? (and works perfectly): http://snag.gy/DKgk9.jpg

And why looks like in Android 5? http://snag.gy/WjVXh.jpg

bringChildToFront function does the same.

I've got the solution!

I only need to put a LinearLayout as father of the scrollView:

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:fitsSystemWindows="true"

<LinearLayout
    android:id="@+id/testlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="70dp"
    android:paddingTop="70dp">

    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
