Layout stretched when setting GridLayout in a ScrollView

I'm trying to put a grid layout in a scroll view but when i put the grid layout in the scrollview all the card inside the grid are stretched like the scroll doesnt get the match parent..
How could i fix that problem?
When i set it normally in the ConstraintLayout all is shown properly.
Here is how it looks like:
While my XML code is the following:

Okay you need to add this line android:fillViewport="true" in you scrollview
ScrollView should be like this
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">

Not showing components following format LinearLayout inside GridLayout contains CardView in LinearLayout

I am implementing card view through GridLayout in android but my card view is not showing up. I want to display main layout is Liner Layout inside Grid Layout its contain Card View . I have tried all things but the card view is not showing up.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>
</androidx.cardview.widget.CardView>
</GridLayout>
</LinearLayout>
</ScrollView>
÷ hope any one fix this problem.

Make the height of the ScrollView as wrap_content as its height is determined at runtime. and also the same for its nested LinearLayout
To make the ImageView & TextView visible use android:gravity="center_vertical" for their surrounding LinearLayout
so change your layout to be:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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_height="wrap_content"
android:background="#drawable/bgapps"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<GridLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:alignmentMode="alignMargins"
android:columnCount="2"
android:columnOrderPreserved="false"
android:rowCount="3">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_rowWeight="1"
android:layout_columnWeight="1"
android:layout_margin="12dp"
app:cardCornerRadius="12dp"
app:cardElevation="6dp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:orientation="vertical"
android:padding="16dp">
<ImageView
android:layout_width="80dp"
android:layout_height="80dp"
android:src="#drawable/bookmark" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="12dp"
android:text="Calendar"
android:textColor="#6f6f6f"
android:textSize="14dp" />
</LinearLayout>
</androidx.cardview.widget.CardView>
</GridLayout>
</LinearLayout>
</ScrollView>
Edit:
Anyone explain why its not showing my GridLayout width as match_parent
I want this :
Solution:
Changes:
Making Gridlayout width to match_parent
Adding android:layout_gravity="center" to the Gridlayout
Making the width & height of all CardViews and underlying
LinearLayouts to "wrap_content" >>>>>> This is the real cause to
the problem.
Making android:gravity="center" to the CardViews underlying
LinearLayout for symmetric purpose >> you can leave it as center_vertical if you wish.

you can ConstrainLayout
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:layout_height="match_parent">
</androidx.constraintlayout.widget.ConstraintLayout>

Anyone explain why its not showing my GridLayout width as match_parent
I want this :

Cardview is not visible when launching on my device

I'm attempting to use a cardview to show 2 images. Everything seems to work in android studio and i can see my layouts in the design tab perfectly. However, when i run on my tablet the cardview is not showing. The layout is working for a virtual device but not for my personal device.

Things i've tried:
adding the dependency: implementation 'com.android.support:cardview-v7:28.0.0'
adding: android:hardwareAccelerated="true" to the manifest file
dragging the layouts in rather than coding them
I know it seems a bit basic, but been stuck for a while and can't seem to find a fix. Any help is much appreciated.

your layout hight is 0. I guess that's the problem.

Any help will be highly appreciated.

You assign android:weightSum="6" to the complete LinearLayout. Therefore, the RelativeLayout makes up a sixth of the total height (android:layout_weight="1"). As your GridLayout is quite large (in relation to your FrameLayout) the FrameLayout becomes big, too (one fifth of the GridLayout to be exact). The image is not large enough to fill the entire FrameLayout and you see that extra space.
You shouldn't use weights in your case. Just assign wrap_content to both your RelativeLayout's and GridLayout's android:layout_height.
Here you can find further explanation about layout weights: https://developer.android.com/guide/topics/ui/layout/linear.html
