Dynamic view height in constraint layout with chain style packed/spread

It has been quite some time since I used XML layout for Android. I am struggling with what seems to be very simple thing, yet I cannot find a quick solution.
I have a constraintLayout with an image, title, description and a button:
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context=".FirstFragment">
<ImageView
android:id="#+id/image_cover"
android:layout_width="200dp"
android:layout_height="300dp"
android:layout_marginStart="10dp"
android:layout_marginTop="10dp"
android:background="#android:color/holo_red_dark"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginHorizontal="5dp"
android:textColor="#color/black"
android:textSize="24sp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#id/image_cover"
app:layout_constraintTop_toTopOf="#id/image_cover"
tools:text="Title" />
<TextView
android:id="#+id/description"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/title"
app:layout_constraintStart_toStartOf="#id/title"
app:layout_constraintBottom_toTopOf="#id/button"
app:layout_constraintEnd_toEndOf="#id/title"
app:layout_constraintVertical_bias="0.0"
app:layout_constraintVertical_chainStyle="spread_inside"
android:text="#string/some_very_long_text"/>
<Button
android:id="#+id/button"
app:layout_constraintTop_toBottomOf="#id/description"
app:layout_constraintBottom_toBottomOf="#id/image_cover"
app:layout_constraintStart_toStartOf="#id/title"
android:layout_width="wrap_content"
android:padding="0dp"
android:layout_margin="0dp"
android:background="#color/black"
android:text="Button"
android:layout_height="36dp"/>
</androidx.constraintlayout.widget.ConstraintLayout>
I want to achieve the following result when the description is short:
Description is aligned to bottom of the title and button aligned to bottom of the image
The following result when description is long:
the button is pushed down/aligned to bottom of the description
I tried to create a chain with either packed (and vertical bias) or spread-inside, however I am only able to achieve either result 1 or 2 and not both.
The idea to do it in XML only, not in Java/Kotlin code.

Since you specify that the button is 39dp in height, you can set a Space widget 39dp from the bottom of the description using a bottom margin. Now set a barrier with a direction = bottom to the Space widget and the description. Now the barrier will float between the bottom of the Space widget and the bottom of the description and will alight on whichever is lower.
Now you can set the top of the button to the bottom of the Barrier and the button will float. The XML is below.
<androidx.constraintlayout.widget.ConstraintLayout

<Space
android:id="#+id/space"
android:layout_width="wrap_content"

app:layout_constraintStart_toStartOf="#id/title" />
<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"

</androidx.constraintlayout.widget.ConstraintLayout>
If you don't explicitly know the height of the button, you can create an invisible clone of the button with the same constraints and use the invisible button for the barrier.
Here is another version that also works, but I am not sure why. It doesn't use a Space.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".FirstFragment">
<ImageView
android:id="#+id/image_cover"
android:layout_width="200dp"
android:layout_height="300dp"
android:layout_marginStart="10dp"
android:layout_marginTop="10dp"
android:background="#android:color/holo_red_dark"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginHorizontal="5dp"
android:text="Title"
android:textColor="#color/black"
android:textSize="24sp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#id/image_cover"
app:layout_constraintTop_toTopOf="#id/image_cover" />
<TextView
android:id="#+id/description"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="#string/some_very_long_text1"
app:layout_constraintBottom_toTopOf="#id/button"
app:layout_constraintEnd_toEndOf="#id/title"
app:layout_constraintStart_toStartOf="#id/title"
app:layout_constraintTop_toBottomOf="#id/title"
app:layout_constraintVertical_bias="0.0"/>
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="36dp"
android:layout_margin="0dp"
android:background="#color/black"
android:padding="0dp"
android:text="Button"
app:layout_constraintBottom_toBottomOf="#id/barrier"
app:layout_constraintStart_toStartOf="#id/title" />
<androidx.constraintlayout.widget.Barrier
android:id="#+id/barrier"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:barrierDirection="bottom"
app:constraint_referenced_ids="image_cover,description" />
</androidx.constraintlayout.widget.ConstraintLayout>
Update: I was curious about the last layout above. Although it works, I wouldn't use it and I have come to the conclusion that it is a bug since the barrier is located below the button but should be immediately below either the description or the image cover. I am using "androidx.constraintlayout:constraintlayout:2.1.4".
More: I no longer think that this is a bug but a reasonable resolution to a, seemingly, impossible condition: The barrier is positioned to the bottom of the TextView and ImageView. The button's bottom is constrained to the barrier while the TextView's bottom is constrained to top of the button. If the barrier is positioned immediately below its referenced views then the wrap_content height of the TextView cannot be honored since the button will intrude into the TextView height (For the long text.)
What is pictured above could be a compromise. The barrier is still below its referenced views, although much farther below, and all constraints and layout sizes can be honored.
It's hard to tell if this is intentional or not or if it will continue to be the case going forward. I believe that the Space solution is the better solution.

How to remove space between cardview and button

I want to remove extra space inside the CardView so the buttons does not have a white border as shown in the picture . This image was captured from my tablet but the Layout looks well in 5 Inch Mobile devices
<LinearLayout

</LinearLayout>
This is the code for the CardViews and the buttons. I didn't paste the whole layout code because I don't think it has effect on my problem and by the way I tried changing margins of the buttons but it didn't solve my problem

From library documentation it is nowhere mentioned that you need to use can completely remove the cardview as it seems unnecessary. You can remove your cardview and enclose your button directly in MaterialRippleLayout to achieve your ripple effect. Check library description here https://github.com/balysv/material-ripple.

screenshot I want

Add this attribute to both your articleAuthor and articleTitle TextViews:
app:layout_constraintEnd_toStartOf="#id/guideline"
Additionally, set the layout_width attribute to 0dp (i.e. "match constraints") for both of these same views:
android:layout_width="0dp"
This will cause the TextViews to be exactly as wide as the space between the left edge of the parent and the right edge of the guideline. For text that is shorter than this width, you'll get one line of left-justified text. For text that is longer than this width, you'll get multiple lines of left-justified text that wrap before the ImageView.

How to design Chips layout for long text

I want go design chip layout like below.
When Text is short enough to fit withing the layout I want to view like this.
When Text is too long to fit in I want it display like this and animate text horizontally.
Is it possible to design a layout that fulfill both about needs.
I have tried solution and i have filed because those layout designs only fulfill one condition.
Solution one
<RelativeLayout
android:id="#+id/relative_store_name_container"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginEnd="10dp"
android:layout_weight="9"
android:visibility="visible">
<FrameLayout
android:id="#+id/relative_shop_name_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/relative_shop_name_text"
android:layout_width="wrap_content"
android:layout_height="21dp"
android:background="#drawable/selected_store_name_text_background"
android:gravity="center_vertical"
android:maxLines="1"
android:paddingStart="10dp"
android:ellipsize="marquee"
android:text="" />
</FrameLayout>
<FrameLayout
android:id="#+id/relative_layout_delete_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="10dp"
android:layout_toEndOf="#id/relative_shop_name_container">
<ImageView
android:layout_width="wrap_content"
android:layout_height="21dp"
android:background="#drawable/selected_store_name_delete_background"
android:paddingEnd="5dp"
android:paddingStart="10dp"
android:src="#drawable/store_name_chip_delete" />
</FrameLayout>
</RelativeLayout>
Problem with this is when text is too long delete button disappears. this layout on work for short text.
Solution two
<LinearLayout
android:id="#+id/store_name_liner_container"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginEnd="10dp"
android:layout_weight="9"
android:orientation="horizontal"
android:visibility="visible"
>
<LinearLayout
android:id="#+id/liner_shop_name_container"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="9">
<TextView
android:id="#+id/liner_shop_name_text"
android:layout_width="wrap_content"
android:layout_height="21dp"
android:background="#drawable/selected_store_name_text_background"
android:gravity="center_vertical"
android:maxLines="1"
android:paddingStart="10dp"
android:text="short Text" />
</LinearLayout>
<FrameLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="10dp"
android:layout_weight="1">
<ImageView
android:layout_width="wrap_content"
android:layout_height="21dp"
android:background="#drawable/selected_store_name_delete_background"
android:paddingEnd="5dp"
android:paddingStart="10dp"
android:src="#drawable/store_name_chip_delete"
/>
</FrameLayout>
</LinearLayout>
Problem with this is when text is short delete button is not going to fit just after text. I can't make that happen by removing weight from both text view container and delete image view container but then I get the same problem in my solution one.
Please give solution to handle this.

You need to make a custom view. That way you can measure the text and resize to fit.

Just add ellipsize="end" to your chip
Just add **ellipsize="end"** to your chip
<com.google.android.material.chip.Chip
<-- android:ellipsize="end" -->
/>

Aligning two images and text in LinearLayout

I want to align two pictures and text. When the first picture is commented out, the text and the second picture are aligned in the middle of a card. But the first picture is always aligned to bottom of the card. I tried all layout properties so far without luck.
See the screenshot for example. I do not understand why the circle is bigger than OK button because when I open these files they have the same dimensions. Where is the issue? I want to use LinearLayout as the simplest layout manager available.
<android.support.v7.widget.CardView
android:layout_gravity="center"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_marginRight="8dp"
android:layout_marginLeft="8dp"
android:layout_marginBottom="4dp"
android:layout_marginTop="4dp"
app:cardCornerRadius="4dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginTop="14dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/badge_type"
android:src="#drawable/ic_gold_circle"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/badge_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="10dp"
android:layout_marginLeft="10dp"
android:text="#string/badge_title_KNIGHT"
style="#style/PlayRecordHeader"
/>
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1" />
<ImageView
android:id="#+id/badge_status"
android:src="#drawable/ic_correct"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="8dp"/>
</LinearLayout>
</android.support.v7.widget.CardView>
Update with layout_gravity="center_vertical"

I think you have to keep
android:layout_gravity="center_vertical"
and remove
android:layout_marginLeft="16dp"
android:layout_marginTop="14dp"
in the LinearLayout
