How to implement snapping in CollapsingToolbarLayout? - android

I have a collapsing toolbar layout, below that a tab layout and below that the corresponding viewpager. I want to implement snapping such that when I collapse the collapsing toolbar layout more than half and leave it, it should snap and collapse completely. How do I do it? Here is my actual layout :

I do not want collapsing toolbar to scroll at all inside coordinator layout

I have a code here which contains of a coordinator layout. Inside that coordinator layout, there is an appbar layout and a nested scrollview beneath it.I want the appbar layout(map) to be still even when nestedscroll view scrolls.I have images to explain my thoughts. Initial stage, stage two. Notice that the map remains still while only nested scroll view scrolls and finally, nested scroll view overlaps entire map fragment.

Try adding
app:behavior_overlapTop="0dp" in your nested scroll view and also add some elevation to the nested scroll view.

NestedScrollView doesnt show cards with wrap content and dynamic data

I have an activity with view pager and I'm loading fragments which has NestedScrollView as parent with cards in it. The data in the card is loaded dynamically and doesn't have fixed height. The card's height is set to wrap_content.
The problem is that the NestedScrollView is not displaying the cards properly after the data is loaded. In some cases the cards overlap each other, while in some, the cards are not visible at all (usually the last).

CollapsingToolbarLayout collapsed with nested scrollview by default

I don't understand why my CollapsingToolbar layout is collapsed when my view is created by default.
I think this the NestedScrollView the responsible but i don't no why.
This make me crazy.
My activity layout :
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
android:fitsSystemWindows="true"

app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v4.view.ViewPager
android:id="#+id/pager_images"
android:layout_width="match_parent"

Rendering :
More strange it still working when i use the NestedScrollView to top. It seems like the NestedScrollView scroll to bottom automatically.

Solved with this thread :
nestedscrollview-scroll-down-itself-when-content-is-fills
android:descendantFocusability="blocksDescendants" to the LinearLayout inside NestedScrollView
Worked for me.

Pull down zoom view inside the android collapsing layout

Collapsing layout image will only collapse and expand. Pull-down zoom view is not supported in the nested scroll view. If we zoom in on the image it does not actually zoom. What is the solution to zooming the image during pull down?
