How to fix some views in Relative Layout

I have implemented simple relative layout for chat inside one of fragments layout called "Chat". The problem is that when I click EditText to type message, Linear Layout for sending messages disappears and messages are superimposed on the items above(I want them no to overlay any element except recycler view).
How to fix it?
Below I put the code of layout and screenshots Layout and Layout after click

Problem 1:
When i set the second cardview height to match_parent then it takes the full screen instead of the left screen at the bottom. It means it will override the first cardview also and reach to the top of parent/screen. So in this case why the set constraint toptobottomof is not working and how can i make it work? As far as i know toptobottomof makes sure that your second view will always remain below of first view which in this case is not working.
Problem 2:
If i keep my layout as it is then the problem is the LineChart is not expanding at all. It is compressing the whole chart height into the wrap content height. It is not behaving like it needs more space as this is what wrap_content attribute is made for instead it is restricting the chart itself to that available height and its not expanding the cardview height at all.
Please help me with these issues.

Change height to 0dp of android.support.v7.widget.CardView , width to 0dp
and use app:layout_constraintBottom_toBottomOf="parent"
This will make the height fill to the parent
Add these
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
Example
<androidx.cardview.widget.CardView
android:id="#+id/card_topplayer"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_margin="#dimen/_5sdp"
android:elevation="#dimen/_8sdp"
app:cardCornerRadius="#dimen/_10sdp"
app:cardPreventCornerOverlap="false"
app:cardUseCompatPadding="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/win_card">
Update
To implement scrollview use fillviewport = true
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:fillViewport = "true"
android:layout_height="0dp">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
And Remove this app:layout_constraintEnd_toEndOf="parent" from second cardview like this
<android.support.v7.widget.CardView
android:id="#+id/card_topplayer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="#dimen/_5sdp"
android:elevation="#dimen/_8sdp"
app:cardCornerRadius="#dimen/_10sdp"
app:cardPreventCornerOverlap="false"
app:cardUseCompatPadding="true"
app:layout_constraintTop_toBottomOf="#+id/win_card"

Layout Problems - Not able to create layout properly in android

I am creating a layout in android but the problem is layout is not created as same in design.
I want to create layout like below image i.e.
but the problem is my design distort in some devices like
enter image description here
<RelativeLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/lay1"
android:layout_margin="#dimen/dp20"
>
<ImageView android:id="#+id/kk"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/move_stock_bar"
android:background="#android:color/transparent"
android:scaleType="centerCrop"
/>
<ImageButton android:id="#+id/ibPlus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_alignParentRight="true"
android:background="#android:color/transparent"
android:src="#drawable/btn_edit"
android:layout_toRightOf="#id/kk"
android:layout_marginLeft="-100dp"
android:layout_marginTop="#dimen/dp10"
/>
<ImageButton android:id="#+id/ibMinus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_alignParentRight="true"
android:background="#android:color/transparent"
android:src="#drawable/btn_edit"
android:layout_toRightOf="#id/kk"
android:layout_below="#id/ibPlus"
android:layout_marginLeft="-100dp"
android:layout_marginTop="-40dp"
/>
</RelativeLayout>

#mishti I have just used this concept to make the design appear to like what you gave. Try this with ImageView using the weight. It displays the same to all screens if we use weight.
<LinearLayout

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="10">
<Button

android:layout_weight="6"
android:text="Image View"/>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_weight="4"
android:layout_gravity="start"
android:gravity="start">
<ImageView
android:layout_marginTop="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/edit_icon"
android:background="#FF0"
android:layout_gravity="start"
/>
<ImageView
android:layout_marginTop="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/edit_icon"
android:background="#FF0"
android:layout_gravity="start"
/>
</LinearLayout>
</LinearLayout>

Use ConstraintLayout for complex layout, it provides you more flexiblity. I did the same layout as in the image attached with question. I am using Guidelines, so i can use this same layout on different screen size and it will work fine.
I am using "app:srcCompat" attribute for setting the image because i am using Vector image here.

RecycleView get cuts at Bottom

This question is raised by so many people but for my case those solution and tips are not working.
I'm using RecycleView in fragment to display gridview for product display but is't cut last item at bottomside, I have gone through many solution like android:clipToPadding="false" and android:paddingBottom="myactionbarsize" but eventually it's doen't work.
Have a look at my code

and how I initialize in my fragment
rv_vendors = view.findViewById(R.id.rv_vendors);
rv_vendors.setHasFixedSize(true);
rv_vendors.setLayoutManager(new GridLayoutManager(mContext, 2));
Here are my Screenshot of emulator Pixel API 24 which cuts the layout at bottom.
and other one which is MIA1 real device Screenshot it's perfect with same propertie.
how this happens any hints ?

Android: LinearLayout going out of screen when using weight

Why is 3rd linear layout (containg two text views) being pushed out of screen in following xml file? Simultaneous design in Android Studio is showing expected behaviour but when testing in phone, 3rd linear layout is being partially visible.
What I am trying to achieve is dividing screen into 3 parts (10%, 80% and 10%).

Even this xml is also being pushed out of screen-

I am using Fragment (Tabbed Activity). When using same xml layout (above snippets) in activity, things are working fine. Problem seems with Fragment.

To avoid nested weights (bad for performance), you can use Relative layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="#+id/topBar"
android:orientation="horizontal"
android:layout_alignParentTop="true"/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="40dp"
android:layout_marginBottom="40dp"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="#+id/bottomBar"
android:orientation="horizontal"
android:layout_alignParentBottom="true"/>
</RelativeLayout>

Instead of using nested weights, which happen to be terribly bad for performance, use ConstraintLayout which is very easy to implement in the layout editor.
If you have never used it before it can appear to be a bit complicated; but that is not the case. Refer to this link to get an idea on how to implement a ConstraintLayout.
Here is the code for what you want to achieve
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

Found it! Problem was not with fragment layout but its container, i.e. ViewPager. I am using Tabbed Activity and by default View Pager was too long (going out of screen).
Here is the solution: Android Tabbed Activity Bottom off Screen
Thanks for effort guys.

Hiiii
I think you don't have proper info, how to use "Weightsum".
well no issue, i will explain you,
When you want to use "Weight" in linear layout you should use "Weightsum" in your main "LinearLayout" after that you can use sub layout or widgets in sum of weight like below code.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1"
android:orientation="horizontal">
<TextView
android:id="#+id/messageTextView"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="0.5"
android:text="Place a stone" />
<Button
android:id="#+id/resetButton"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:layout_width="0dp"
android:text="Reset" />
</LinearLayout>
