Android: CollapsingToolBar do not setting at one level the icons with the title that appears in the bottom of toolbar after collapse

Screen after collapsed
Using CollapsedToolbarLayout: when picture is hiden and collapsed, the title is going to the top(in toolbar), but not on the same level(line) with the back(and menu) icons. Where can there be a mistake? (Everything is put inside CoordinatorLayout with width and height = match_parent and fitsSystemWindows="true")

Collapsing Toolbar Layout with Custom Toolbar

I've been experimenting with CollapsingToolbarLayout in Android. I am trying to change the shape of the Toolbar when it's collapsed. And like this when collapsed.
I want the Toolbar to look something like this when collapsed. I can do it to a normal Toolbar when it's not in a CollapsingToolbarLayout by creating a custom background for it as shown above. But I'm not able to set it to the toolbar in CollapsingToolbarLayout as setting a background simply leads it to showing up in the expanded view and then shifting upwards when in collapsed form.
Any idea how this can be implemented?
XML Code for the CollapsingToolbar

How to reduce left and bottom space from toolbar title in collapsing action bar android?

I need to reduce left and bottom space from toolbar title in collapsing action bar. I need to do something like whats app. Here is my code.
Thanks for help.
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="300dp"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/img_profile"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/speaker1"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

add this below in your activity where you are setting the title
mBinding.collapseToolbar.setExpandedTitleMarginBottom((int) getResources().getDimension(R.dimen.contact_info_expanded_title_margin));
mBinding.collapseToolbar.setExpandedTitleMarginStart((int) getResources().getDimension(R.dimen.contact_info_expanded_title_margin));
mBinding.collapseToolbar.setTitle("Toolbar title");

AppBarLayout change offset programmatically

How can I change the offset of the AppBarLayout programmatically?
I want a certain offset to the AppBarLayout(partially expanded) when the Activity first loads, then the user could expand it more or collapse it. The current behaviour is that it's fully expanded when the Activity first loads.
my.xml
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="300dp"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:fitsSystemWindows="true"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_collapseParallaxMultiplier="0.7"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_collapseMode="parallax">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="#drawable/pic"/>
<View
android:id="#+id/overlay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/overlay"
app:layout_collapseMode="pin"/>
</FrameLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:title="#string/app_name"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
Need to support API 16+
Thanks!

Use this: ScrollableAppBar
You just have to replace your AppBarLayout with:
<it.michelelacorte.scrollableappbar.ScrollableAppBar
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="380dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
</it.michelelacorte.scrollableappbar.ScrollableAppBar>
and than:
ScrollableAppBar appBarLayout = (ScrollableAppBar) findViewById(R.id.appbar);
//To give the effect "in the middle" of the image (like gif)
appBarLayout.collapseToolbar();
Output:

CollapsingToolbarLayout title overlaps MenuIcons (it doesn't truncate)

I have a problem with long titles in CollapsingToolbarLayout. It looks like this (on the right there is phone and overflow icons):
Code for this (and yes, I know that FAB is wrongly placed, but I keep it just for debug purposes - don't mind it please). I just want title to end (truncate) where icons start):
