Not able to properly nest GridView inside Cardview

I use a RecyclerView , which renders CardView . This CardView has 2 TextViews and one GridView , The GridView renders CardView (lets call it inside_card )as its child. Now i am unable to change height of this inside_card . Given below is what i want to achieve(Image A) and what i am getting (Image B).
Given Below are my Layouts.
activity_main.xml contains RecylerView

Change in inside_card.xml
-> Increase the height of card view from 45dp to 120dp, tweak as per requirement
-> Set card elevation 0dp, as in the design A, there is no card elevation.
-> Even I will suggest, don't take card view for this, Just take simple LienarLayout and set a drawable shape with stroke for this. Because Setting border on card view is a little tedious task.

In your GridView, set vertical spacing too
<GridView
android:layout_gravity="center"
android:id="#+id/unitsGrid"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_weight="1"

android:verticalSpacing="15dp"
android:numColumns="2"></GridView>

Android App intellij Layout_marginBottom is adding to top

So I have this code in an XML file:
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="500dp"
android:id="#+id/constraintLayout" app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="#+id/text_dashboard">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/scrollView2">
<RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_marginEnd="18dp" android:layout_marginStart="10dp"
android:layout_alignParentBottom="true"
android:layout_marginBottom="50dp" android:layout_margin="0dp"/>
</RelativeLayout>
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
The bottom margin within text view is adding to the top not the bottom, and the text at the bottom of the scroll view gets cut off. Also, when I try to just move the layout instead, if I drag it downward, it moves upward after release, and vice versa for dragging upward. Does anyone know what is happening here???

How to design this Grid view xml page?

I want to design xml page this type. I tried many of the code. Every time new problems are come. I need bottom navigation bar is fixed. In grid view ,i want android:numColums=3, android:verticalSpacing and android:horizontalSpacing Same(Look like instagram profile view grid images ).
XMl Code:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".MainSettingClass">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="175dp"
android:background="#dadada"
android:gravity="center"
android:orientation="vertical">
<ImageView
android:id="#+id/profile_image"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/com_facebook_button_background"/>
<TextView
android:id="#+id/amsc_txt_fbusername"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="TextView"
android:layout_marginTop="2dp" />
</LinearLayout>
<GridView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/grid_test"
android:verticalSpacing="2dp"
android:horizontalSpacing="2dp"
android:background="#FFFFFF"
android:stretchMode="columnWidth"
android:columnWidth="85dp"
android:numColumns="3"/>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_gallery"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#ffffff"
app:menu="#menu/bottom_navigation_gallery"/>
</FrameLayout>

As per your design you need scrollview for 2 above components and your BottomNavigationView is fix (not movable).
In your code you are not using scrollview first and second i'm not sure why you're using framelayout!
Here's my code which is exactly as per your given design try this if any concern you can ask! :)
Here's my code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ScrollView
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottom_gallery">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/rel_titleHolder"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#dadada"
android:gravity="center"
android:orientation="vertical">
<ImageView
android:id="#+id/profile_image"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#mipmap/ic_launcher" />
<TextView
android:id="#+id/amsc_txt_fbusername"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:gravity="center"
android:text="TextView" />
</LinearLayout>
<GridView
android:id="#+id/grid_test"
android:layout_width="match_parent"
android:layout_height="400dp"
android:columnWidth="85dp"
android:horizontalSpacing="2dp"
android:numColumns="3"/>
</LinearLayout>
</ScrollView>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_gallery"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
android:layout_alignParentBottom="true" />
</RelativeLayout>

Why is the bottom of my fragment not displaying?

I created the following DialogFragment in XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/mainLayout"

android:layout_width="match_parent"

android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/quoteLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/buttonLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
<Button
android:id="#id/getMoreButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/getMore"
android:onClick="getMore" />
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/adLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
ads:adSize="BANNER"
ads:adUnitId="#string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>
</LinearLayout>
</LinearLayout>
I've been working along on the quoteLayout section and have it performing as I wish. Now I wanted to fill the other sections with a button and an ad.
The problem is that nothing still shows up in the other parts of the mainLayout. The end of the screen is the end of the quoteLayout.
Any ideas?

You have it orientation set as vertical but in your linearlayout children you have the android:layout_height attribute as match_parent which fills up the layout. It should be wrap_content or use weights to better organize how it should look. At least, that's what looks wrong to me. Try swapping out match_parent to wrap_content or use weight attribute. Note that if you use weight set android:layout_height' to0dp.`
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/mainLayout"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/quoteLayout"

android:paddingRight="0dp"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

ads:adUnitId="#string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>
</LinearLayout>

You have set your quote layout to match_height within another LinearLayout that also matches height. Your button layout and adLayout are simply off the bottom of the screen.
To fix this, I would use layout weights like so:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/mainLayout"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/quoteLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.5"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/buttonLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.3"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
<Button
android:id="#id/getMoreButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/getMore"
android:onClick="getMore" />
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#id/adLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.2"
android:paddingLeft="5dp"
android:paddingRight="0dp"
android:orientation="vertical" >
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
ads:adSize="BANNER"
ads:adUnitId="#string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>
</LinearLayout>
</LinearLayout>
Notice that I have changed layout_height to 0dp and added a layout_weight tag. This tag makes it so that your layout will adjust to a certain percentage of the height based on the values entered.
You could also use wrap_content for height.

Android ImageView getting over linearlayout

I'm developing an android application, The layout is shown in the image below :
Screenshot http://www.lebanon-trading-center.com/daymanager/layout.PNG
The layout contains 2 main linearlayouts : a horizontal layout that takes 90% of the height of the device and a vertical layout that takes 10% of it. Inside the horizontal linearlayout there is three linearlayout ( two red and one containing an imageview). Each red layout is 10% of the width of the screen and the one containing the ImageView is 80%. Here is the xml code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="0.9"
android:weightSum="1"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_weight="0.1"
android:background="#ff0000" >
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal"
android:gravity="center_horizontal"
android:layout_weight="0.8" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_weight="0.1"
android:background="#ff0000" >
</LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="0.1"
android:background="#000000" >
</LinearLayout>
</LinearLayout>
The problem is, when I set a PNG image (1036px X 730px ) as a source to the ImageView, the ImageView will get over the bottom linearlayout ( the black one ) and the two red layouts will be squeezed.
Screenshot http://www.lebanon-trading-center.com/daymanager/layout2.PNG
My question is how can I solve the problem and have the same layouts functional on all kind of tablets ?

Try this way,hope this will help you to solve your problem.
