CardView not fully Scrollable on my fragment

I am using a fragment to display cardview and a common Bottomnavigation for all fragments. Here I have more than 5 cards as per my data but I am not able to scroll to see all cards. only scrollable up to the second card and the second one is also not fully visible due to the bottom navigation.

Please check my code and help me with this.

This is wrong in your main_activity.xml for fragment android:layout_above="#id/nav_view", it is used for RelativeLayout. Instead use app:layout_constraintBottom_toTopOf="#id/nav_view". This will solve your second issue(the second one is also not fully visible due to the bottom navigation).
Change your ScrollView to NestedScrollView.
In your cardview content you don't need ConstraintLayout, LinearLayout is sufficient as root element (remove ConstraintLayout as you are not utilising its power of flat view hierarchy). And if your LinearLayout background can be moved to background for MaterialCardView then you don't need LinearLayout too.
For your recyclerview set the nestedScrollingEnabled to false either through xml or by code. Try these things, it will solve your problem.

How to set layout height fix in android?

I have created one layout in android. the issue I am facing is in some case there are two lines of description and in some cases there is only one line of description. and My layout height automatically adjust base on that. but I want to fix my layout height in every case. means my layout height should be equal in every case.

You can add in the description TextView this attribute: android:minLines="2"

fill rest of the space using linearlayout

I have a FoodCardFragment that has a CardView at the bottom. I want the CardView to have a height of at least 120dp and fill the rest of the space (so I set its layout_weight to 1).
The FoodCardFragment is put in the RandomFragment (the first tab of MainAcitivity), and also has its layout_weight set to 1 as I want it to fill the rest of the space.
However, as you can tell from the image I posted below, the yellow CardView I mentioned above doesn't fill the rest of the space. How can I achieve my goal?
In case the links won't work:

I am currently using RelativeLayout as the Root Element, and for each row, I am applying a horizontal LinearLayout followed by a vertical LinearLayout.
Based on my current layout, can I receive assistance on how to place the divider lines on my interface, much like the provided picture?
Thank you!

First of all, I would recomend you to use RecyclerView with GridLayoutManager for this purpose. creating recyclerview with gridmanager
but if you want stick with current design, you add line by creating a View in xml
For Vertical line
<View
android:layout_width="2dp" //thickness
android:layout_height="match_parent"
android:background="#color/colorPrimary" />
For Horizontal line
<View
android:layout_width="match_parent"
android:layout_height="2dp"//thickness
android:background="#color/colorPrimary" />
for shading colors you should look for something like Gradient in android. How ro create Gradient in android
code looks like this.

Button under recyclerview is not visible

I'm progrmming app with RecyclerView and bottom buttons. RecyclerView is filling by images, that I got from the server. Top bar is fixed
http://joxi.ru/KAxee4XTEMpPr8
RecyclerView code
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
RecyclerView is filling by ImageViews
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="100dp"
android:scaleType="centerCrop"
android:layout_marginBottom="1dp"
android:layout_marginEnd="1dp"
android:layout_marginStart="1dp"
android:layout_marginTop="1dp" />
Buttons code that invisible

I solved that in another way. I gave a PaddingBottom in RecyclerView calculating the Size of the Button. For example, if total size of button is 40 dp, I gave PaddingBottom 50dp. That's why, Button is not overlap with RecyclerView

Here width of TextView is (15+10+7+7) ~ 40dp. So I gave PaddingBottom 50dp in RecyclerView
