</style>

to fix that you need to add android:fitsSystemWindows="true" from root to every child view until the view that you want to show below the status bar and just set android:fitsSystemWindows="false" to those views you want to get auto padding according to status bar height so this will fix the padding issue on image view but now that black gradient act weird and being to the size of the toolbar to fix that i have manually set padding to gradient in code using window insets check code below for that

Originally, I used NestScollView for areas other than AppBarLayout. I tried to change it to a separate xml, and found it invalid. I also tried to add android: fitsSystemWindows="true" to her, which is also invalid

Android Collapsed Toolbar overflow menu has background

I'm using a collapsing toolbar layout in an activity which should have to items always shown in the overflow menu. the issue is that as you can see below (on the top right corner) both items has a background of the collapsed toolbar instead of being on top of the cover image directly like the back arrow.
All used drawables are vector drawables without background.

Removing the theme from toolbar
android:theme="#style/ToolbarTheme" didn't solve the issue, applying a theme that overrides the parent with a transparent background did.

Toolbar elevation/shadow (for pre lollipop) when using CollapsingToolbarLayout

Below is the code I am using to have a collapsing toolbar. It works. But at the same time I am trying to have toolbar elevation which is not working in pre lollipop devices, so I am trying to do that by applying a view with a shadow drawable. It works, but in this case, has an unintended effect as the shadow is visible all the time (see below)
I want the shadow to be visible only when only the toolbar is visible
Any advise?

This is a bug, you can find here is Assigend as Small-Priority to Chris Banes (Android Developer).
https://code.google.com/p/android/issues/detail?id=182083
I suggest you to add the custom shadow view as foreground in your fragment container.
i did same thing in my code like:
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
**android:foreground="#drawable/header_shadow"**>
You can do one more thing put
<item name="header_shadow" type="drawable">#null</item>
attibute in value-21 style.xml and before api 21 add it into your styles.xml like this..
<item name="header_shadow" type="drawable">#drawable/bottom_shadow</item>

I add the image view in a framelayout in the toolbar so that i can have a overlay on the image and a gradient to make the toolbar text visible on some images
But this color line is coming just below the image (see screenshot) on adding the framelayout. If I remove the line
android:fitsSystemWindows="true"
from appbarlayout then the the color line disapperas but toolbar also scrolls away from the view...
Also to show the back button on the toolbar I have added the below code in OnCreate still it does not show
toolbar = FindViewById<Android.Support.V7.Widget.Toolbar>(Resource.Id.anim_toolbar);
SetSupportActionBar(toolbar);
SupportActionBar.SetDisplayHomeAsUpEnabled(true);
SupportActionBar.SetHomeButtonEnabled(true);
SupportActionBar.Title = content.Title;
toolbar.SetNavigationIcon(Resource.Drawable.ic_action);
collapsingToolbar = FindViewById<CollapsingToolbarLayout>(Resource.Id.collapsing_toolbar);
collapsingToolbar.SetTitle(content.Title);
Thanks...
OK got it now had to remove
android:fitsSystemWindows="true"
from
<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">
everything good now
Thanks
Consider adding a fixed width to your app bar layout
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="300dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
