CollapsingToolbarLayout with wrap_content height overlaps views

When I set CollapsingToolbarLayout height to wrap content my views get overlaped, but when setting to exact height in this case 195dp ,it works well ,can someone tell me how can I use wrap _content without overlapping the views ? I want the relative layout to be scrolled under the toolbar.
Thx in advance

I want to keep TitleBar visible and stick at top instead of underneath a collapsing toolbar

I have a AppBarLayout with CollapsingToolbar layout and ImageView in it. TitleBar appears when I ScrollUp. But I want to stick it at top and always visible. I have already tried by changing
app:layout_collapseMode attribute.
Also tried
app:layout_scrollFlags="scroll|exitUntilCollapsed|enterAlways"
But didn't worked either. I have a code as follows:
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="#dimen/height"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true"
>
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true"
app:expandedTitleMarginStart="25dp"
app:expandedTitleMarginEnd="60dp">
<ImageView
android:id="#+id/images"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="top"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/window_background"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:layout_width="30dp"
android:layout_height="20dp"
android:id="#+id/viewDetail"
android:text="View Detail"
android:textColor="#ffffff"
android:gravity="bottom|right|end"
android:onClick="onClick"/>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

Finally I found solution to this. I also add ImageView in ScrollBarLayout. Below code worked fine for me !
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="#dimen/height"
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:layout_gravity="top"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/window_background"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/images"
android:layout_width="match_parent"
android:layout_height="200dp"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<TextView
android:layout_width="30dp"
android:layout_height="20dp"
android:id="#+id/viewDetail"
android:text="View Detail"
android:textColor="#ffffff"
android:gravity="bottom|right|end"
android:onClick="onClick"/>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

Android CollapsingToolbarLayout with Toolbar and TabLayout

I'm making an application which uses CollapsingToolbarLayout with Toolbar and TabLayout.
I want to place the TabLayout to below Toolbar when the header is collapsed.
However, When I try to scroll the view, TabLayout overlays the Toolbar like this linked picture:

I solved this problem by using expedient. I made 2 toolbars including the original one. and I made one of those transparent. then, It looks working fine but I think it is not clear way.
