How I can make this:
But expand from bottom???
I was try BottomSheetBehavior, but BottomSheet overlays content.

You can try this. It looks like a CollapasingToolbarLayout:

Use this piece of code to hide your layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>
<!-- Your Remaining Code -->
</android.support.design.widget.CoordinatorLayout>

Try using a collapsingToolbar layout. The material design example is found here but of significance is the below snippet
<com.google.android.material.appbar.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleGravity="top"
app:expandedTitleMarginStart="#dimen/shrine_toolbar_offset_start"
app:expandedTitleMarginTop="#dimen/shrine_toolbar_offset_top"
app:layout_scrollFlags="scroll|exitUntilCollapsed|snap">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/shrine_toolbar_image_offset_top"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.5"/>
<android.support.v7.widget.Toolbar
android:id="#+id/AppBar"
android:layout_width="match_parent"
android:layout_height="#dimen/shrine_toolbar_collapsed_height"
app:layout_collapseMode="pin"/>
</com.google.android.material.appbar.CollapsingToolbarLayout>

transparent status bar with fitsSystemwindows toolbar pushed up

Android Studio 2.3 RC 1
I have created an app that uses a transparent status bar that works ok as the status bar is transparent. The problem is with my toolbar as it seems to get pushed up. I have been trying to solve this issue using fitsSystemWindows to true. However, this has not worked.
Just wondering if there is something I am doing wrong.
The layout:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="me.androidbox.busbymovies.movielist.MovieListViewImp">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbarlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
app:contentScrim="#color/primary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/tool_bar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/primary"
android:fitsSystemWindows="true"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="parallax">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/rvMovieList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/tool_bar"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<android.support.v4.widget.ContentLoadingProgressBar
android:id="#+id/pbMovieList"
style="#style/Widget.AppCompat.ProgressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
</android.support.design.widget.CoordinatorLayout>
My styles:
<style name="AppTheme" parent="BaseTheme">
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:navigationBarColor">#android:color/transparent</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
</style>
And in my onCreate(..) in the main activity
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
final Window window = getWindow();
window.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}

I would suggest, since you have this element:
app:layout_collapseMode="parallax"
that you do actually want some kind of parallax when scrolling. So this tells me that what you really meant to do is use a CoordinatorLayout. So this isn't a direct answer to your question but it will work if you use this method and you can fix both problems. I'm taking into account the image I can see in your screenshot.
<android.support.design.widget.CoordinatorLayout
android:fitsSystemWindows="true"
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent">

I found an awesome library named multiline-collapsingtoolbar, which gives you a custom collapsing toolbar that can deal with multiline titles.
Usage
The library's public API is identical to the version from the support library, so you can use it as a drop-in replacement.
As the Design Support Library, it should be compatible with API 7
(Android 2.1) and above.
XML layout example:
<android.support.design.widget.AppBarLayout
android:layout_height="192dp"
android:layout_width="match_parent">
<net.opacapp.multilinecollapsingtoolbar.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
app:layout_collapseMode="pin"/>
</net.opacapp.multilinecollapsingtoolbar.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
You can find a simple demo application in the demo module.

A simpler approach could be add a custom layout to your Collapsing toolbar and pin it when collapsing, this could be the final output:
