The issue I am facing now is the fact that all views inside the Constraint Layout that is inside my CollapsingToolbarLayout are not clickable.
I have checked multiple questions on this subject and none helped me - some suggested to make a custom Toolbar class that overrides onTouchEvent() to false always but when I try to use this class it does not show in the XML editor for some reason.
Other solutions I have found accross the net did not provide me with any usefull solutions.
So how can I make the nested views clickable?

Solved, I added the following line to my CollapsingToolbarLayout -
android:descendantFocusability="blocksDescendants"

NestedScrollView and AppBarLayout in a CoordinatorLayout: inability to scroll until the end of NestedScrollView

I have an activity layout that consists of:
A sticky non-collapsing Toolbar on the top of the page
A NestedScrollView that contains two headers for two RecyclerViews
A ConstraintLayout to position the items inside NestedScrollView
Two RecyclerViews

The toolbar is fixed at the top of the page as I wanted. Everything scrolls correctly. However, I can't scroll until the end of the NestedScrollView, i.e. the item was cut off and I cannot scroll to the last item in the second RecyclerView. How do I fix this?

For some reason, this attribute android:fillViewport="true" on CoordinatorLayout caused it to break. Removing that attribute corrects everything.

Weird behavior of a RecyclerView within CoordinatorLayout

I'm having some trouble with a partly hidden RecyclerView on the small devices below 5.5" (Nexus, A3, etc...)
Once the feed's loaded, and added to the adapter items, all the children of the CoordinatorLayout moved up.
You can see the demo here
Here's the hierarchy of the view:

AppBarLayout
LiveCollapsingToolbarLayout
CardView
ConstraintLayout

[Update]
It seems the problem comes from the horizontal recyclerview that is in live_feed_recyclerview as a ViewHolder

EditText not focusing in CoordinatorLayout with NestedScrollView

I have an EditText that is not allowing to Focus and type. The screen has CoordinatorLayout as a root/parent and NestedScrollView with ViewPager.
On the TOP there WILL be google map and at the bottom there are two tabs.
First tab has text content with EDIT TEXT (which is having the issue) and on the second tab there is a recyclerview.
With this layout unable to Focus and Type on the EditText on the First Tab.

You can force the edit text to gain focus programmatically. Inside your TAB1 java class you can do the following that will force the edit text to gain focus.
EditText editText = findViewById(R.id.test_text); //initialize edit text
editText.requestFocus(); //will request focus
//will force the keyboard to show
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

I'm making a collapsing toolbar in android with custom view.

The collapse functioning of the toolbar is working well but the effect is very bad and it jitters while expanding and collapsing. Below is my layout code. Even sometimes the toolbar becomes quite big. I have used a custom view instead of an image in this code. The custom view is constraint Layout. The particular code inside a fragment and the fragment consists of tab layout that has a recyclerview in it. I have used parallax effect for the custom view so I am not quite sure about it.

Try adding all custom components which are currently present inside CollapsingToolbarLayout into a separate layout file. Then use
<include layout="#layout/my_custom_layout"/>.
Don't know why but works for me somehow. See if this works for you.
