Element LinearLayout is not allowed here - inside RelativeLayout - android

I keep getting an error that my LinearLayout isn't allowed in my RelativeLayout object.
I am trying to create a multi-filter search bar. This LinearLayout is meant to hold different elements in the search bar. Here is my code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
Why is this happening? I made sure it is in the updated androidx CardView, so not sure why LinearLayout is still not allowed to be in the RelativeLayout inside CardView.


It looks like you have a typo in your CardView tag:
<androidx.appcompat.widget.CardView
That should look like this instead:
<androidx.cardview.widget.CardView ...
(Replace .appcompat. with .cardview.).

I have add Relative layout and Code like below.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<android.support.v7.widget.RecyclerView
android:id="#+id/listChatGeneral"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/llSendView" />
<LinearLayout
android:id="#+id/llSendView"
android:layout_width="match_parent"

CardView size issue on View Recycle

I have created a recyclerview adapter class, with an item layout which contains a cardview inside which there are some textviews and imageviews. The problem I am facing is that when the views are recycled, my cardview size changes and it hides the content of another cardview.
I think the issue is because I have different card heights for each item. So when an item is recycled, it takes the height of another card which is different. How to fix this? Please help..

RecyclerView itself a ScrollView .
Solution
Call NestedScrollView instead of ScrollView .
STRUCTURE
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
/>
</android.support.v4.widget.NestedScrollView>
FYI
You should add
recyclerViewOBJ.setNestedScrollingEnabled(false);
If this property is set to true the view will be permitted to initiate
nested scrolling operations with a compatible parent view in the
current hierarchy. If this view does not implement nested scrolling
this will have no effect. Disabling nested scrolling while a nested
scroll is in progress has the effect of stopping the nested scroll.

You should take a scrollview outside of Relative layout

Set your Scrollview to NestedScrollView
<android.support.v4.widget.NestedScrollView>
<android.support.v7.widget.RecyclerView>
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.NestedScrollView>
In your recyclerview
recyclerView.setNestedScrollingEnabled(false);
recyclerView.setHasFixedSize(false);

Collapsing Toolbar hide when scroll up and show when scroll Down

In our chat app new message start first. For see old message user scroll up. For this we set reverseLayout true.
Ex: LayoutManager reverse so 0 position is botttom. when user scroll for old message suppose position is 10 . so i want to hide toolbar.when user go below from 10 position to 9 position i want to show toolbar.
LinearLayoutManager linearLayoutManager = new WrapContentLinearLayoutManager(context);
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
linearLayoutManager.setReverseLayout(true);
We want to hide collapsing toolbar when user scroll up for fetch old message and show collapsing toolbar when user scroll down.
Any hints on how to achieve this?

Bottom Sheet with fab partly outside the borders

I'm trying to implement bottom sheet that will overlap exactly a view not a
whole screen. Desirable
.
But here is actual result
end position
.
What I'm doing wrong?
Here is the code. I want to overlap Textview with id content_to_overlap.
<TextView
android:id="#+id/btn1"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="#399"
android:layout_marginBottom="4dp"
android:clipChildren="false"
android:clipToPadding="false"
android:gravity="center"
android:text="Text1" />
<TextView
android:id="#+id/btn2"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_below="#+id/btn1"
android:background="#399"
android:clipChildren="false"
android:layout_marginBottom="4dp"
android:clipToPadding="false"
android:gravity="center"
android:text="Text2Text2Text2Text2" />
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/btn2"
android:clipChildren="false"
android:clipToPadding="false">
<TextView
android:id="#+id/content_to_overlap"
android:layout_width="match_parent"
android:layout_height="64dp"
android:background="#B44"
android:gravity="center"
android:text="Text3" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="24dp"
android:clipChildren="false"
android:clipToPadding="false"
app:behavior_peekHeight="48dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
android:background="#8FF0"
>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="-48dp" />
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>

Code Below is not perfect but is provided to give you an idea
Use anchor for fab
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<TextView
android:id="#+id/btn1"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="#399"
android:layout_marginBottom="4dp"
android:clipChildren="false"
android:clipToPadding="false"
android:gravity="center"
android:text="Text1" />
<TextView
android:id="#+id/btn2"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_below="#+id/btn1"
android:background="#399"
android:clipChildren="false"
android:layout_marginBottom="4dp"
android:clipToPadding="false"
android:gravity="center"
android:text="Text2Text2Text2Text2" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/btn2"
android:clipChildren="false"
android:clipToPadding="false">
<TextView
android:id="#+id/content_to_overlap"
android:layout_width="match_parent"
android:layout_height="64dp"
android:background="#B44"
app:behavior_peekHeight="48dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
android:background="#8FF0"
android:gravity="center"
android:text="Text3" />
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:anchor="#id/content_to_overlap" />
</android.support.design.widget.CoordinatorLayout>
