How to fix TextView position when text in it changes

I have a layout like in this picture below, containing a title, some text view, and a list view. Title is aligned with the top of the screen, and list is aligned with bottom of the screen and should take as much space as possible.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MyActivity">
<TextView
android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:text="Title"
android:textSize="30sp" />
<TextView
android:id="#+id/some_text"
android:layout_below="#id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="6dp"
android:text="Some random text which can change"
android:textSize="14sp" />
<ScrollView
android:id="#+id/list_wrapper"
android:layout_below="#id/some_text"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
After activity is created, text in text view below title can dynamically change, and when it happens it could shrink and list view could change its size. I want to prevent this, so that list view keeps its position and size, and only text view above shrinks and moves down to the list like in this picture below.
How can I accomplish this? I am okay with any layout type, I just used RelativeLayout code above as an example.
It would be easy if list view could have fixed size, but I want list view to take as much space as possible, and after activity is created I want it to stay in place and not change its size.

You can use ConstraintLayout with guideline to tell your list view and your text view exactly where to be on your screen (It will be responsive to all screen sizes).
It Will look something like this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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">
<ListView
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
android:layout_marginBottom="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#+id/guideline31" />
<TextView
android:id="#+id/tes"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="8dp"
android:layout_marginBottom="8dp"
android:text="Text"
app:layout_constraintBottom_toTopOf="#+id/guideline31"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<android.support.constraint.Guideline
android:id="#+id/guideline31"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.2"/>
</android.support.constraint.ConstraintLayout>
And now your layout will look the same with long text or short text for the title:

just add this line in your textview xml android:maxLines="1"
<TextView
android:id="#+id/title"
android:maxLines="1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:text="Title"
android:textSize="30sp" />

ImageView inside ConstraintLayout does not work

I have a problem with correct display of ImageView. I want to display ImageView inside ConstraintLayout. On preview it looks exactly as i need, but when i'm starting it on device it looks completly dirrerent. This layout is places inside recycle view. What is wrong with this code?
<?xml version="1.0" encoding="utf-8"?>

android:layout_marginBottom="12dp"
android:text="Sampe description" />
</LinearLayout>
EDIT: Deep explanation:
I want to create row for RecycleView. Each row have to contains image, title and description. Title have to be in the left bottom corner of the image. Description have to be below the image. After that i have to put gradient (black in the bottom) into the image. Screen with "Preview" is exactly what i need.
EDIT2: Everything with this layout is ok. It is working as expected, i forget that i made some changes in kotlin code... Sory for problem.

First things first, every view should apply the attribute rules of its parent ViewGroup. ConstraintLayout doesn't support match_parent. It supports the 0dp value which means "match constraint". This way the view will expand to fill the constraint bounded space.
Next, ConstraintLayout was created to achieve a flat view hierarchy for better layout performance. So, never nest it inside a LinearLayout as it has the chains feature to get the same behavior in a more flexible way. Plus, you can achieve the structure with a ConstraintLayout at the top level .
Another thing, If you are going to define the same margin in all directions, you can just use layout_margin.
Finally, you have overdraw problems. ConstraintLayout is flexible enough to allow us to position views as backgrounds and help us avoid overlapped backgrounds.
Here's a solution:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/promotionRow"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="10dp">
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#color/colorPrimary"
app:layout_constraintBottom_toBottomOf="#+id/promotion_image"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageView

android:layout_width="0dp"
android:layout_height="wrap_content"

app:layout_constraintHeight_min="150dp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageView

android:layout_height="80dp"
android:adjustViewBounds="true"
android:background="#drawable/fade_image_background"
app:layout_constraintBottom_toBottomOf="#+id/promotion_image"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent" />
<TextView

android:layout_width="0dp"
android:layout_height="wrap_content"
android:padding="8dp"
android:text="Sample title"

android:textStyle="bold"
app:layout_constraintBottom_toBottomOf="#+id/promotion_image"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent" />
<TextView
android:id="#+id/description"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#android:color/white"
android:padding="12dp"
android:text="Sampe description"
android:textSize="13sp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#+id/promotion_image" />
</android.support.constraint.ConstraintLayout>
Try it. Hope this helps!

First of all, trying to write more presicely what do you want? Display image view inside layout it's somthing common words. As for your code, beside you don't have any constraints. You have strange view height, for second ImageView:
android:layout_height="match_parent"
It may overlay all other children view, it's very strange parameter.

How can I make a two textviews wrap content while maintaining a maximum length?

I'm working on a chat function where I want the users messages appear on the right side and messages from others on the left side. The right side is giving some trouble.
As the message is short, it should stick to the right side of the screen, then the name of the user should be right next to it as shown below (Android developers "show layout bounds" is on):
Just some simple LinearLayout with two TextViews aligned to the right, but you can see this doesn't work with longer messages, as they are clipped off and the name is often invisible at all. I've managed to do this with a constraint layout:
]
The ConstraintLayout (wrapper) has a 100dp constraint to the left for the margin and within it, the name and the message are chained. The downside is that short messages don't stick to the right anymore.
How do I manage the layout to automatically align the way I want?

Maybe this could help you, if you already have a ConstraintLayout, play a little bit more with the possible constraint attributes.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:padding="16dp">

android:paddingEnd="8dp"
android:text="Name"
app:layout_constraintEnd_toStartOf="#id/message"
app:layout_constraintHorizontal_chainStyle="spread_inside"
app:layout_constraintStart_toStartOf="parent"/>
<TextView
android:id="#+id/message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="16dp"

app:layout_constrainedWidth="true"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#id/name2"
app:layout_constraintTop_toBottomOf="#id/message"/>
</android.support.constraint.ConstraintLayout>
The magic is: app:layout_constrainedWidth="true" which takes care about the maximum width of the view, depending on the surrounding views (simply constraint with toStartOf ... EndOf)(see: https://developer.android.com/reference/android/support/constraint/ConstraintLayout).
Also app:layout_constraintHorizontal_chainStyle="spread_inside" takes care, that the views always alligned to the maximum left and right, this is Chaining in constraint layouts (https://developer.android.com/training/constraint-layout/)
Hope it helps you to solve your problem.

You should be able to manage this functionality by implementing the constraint Guideline.
With this, you can split your entire layout vertically and separate user messages and responses while formatting each side individually.
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/guideline"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5" />
Try using something like this:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"

Constraint Layout Getting a default top margin for imageview

I am trying to create a layout using constraint layout, with an ImageView on top, a button in the ImageView, a TextView below it and then another TextView below it. Following is the xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView

</android.support.constraint.ConstraintLayout>
</RelativeLayout>
</android.support.v7.widget.CardView>
Everything is correct except for a small margin on top of the first ImageView. Whatever I do I cannot get rid of that margin. See the image below.
Please note the margin between the top of the ImageView and the card, that is what is troubling me.

Your news_image, news_title1, and news_read_more1 views form a chain. Apparently, though I cannot find documentation on this, all views in a vertical chain will share vertical margins. In other words, applying a layout_marginTop or layout_marginBottom attribute to one of those three views will wind up applying it to all three of them.
You will have to re-allocate your margins, keeping this in mind.
Edit
Looks like the behavior is a little more sophisticated than I thought. First of all, it looks like it only applies to views with the spread "chain style" (which is the default). Second, it looks like top margin is applied to the view it is specified on as well as all views above that one in the chain, while bottom margin is applied to the view it is specified on as well as all views below that one in the chain. Finally, it appears that margins are cumulative (so if you had 10dp top margin on your bottom view and 20dp top margin on your middle view, the final result would be 30dp on your top view, 30dp on your middle view, and 10dp on your bottom view).
As for how to solve this problem in your specific case? You should be able to use left/right margins without issue. And then probably you should use bottom margin on your top view to space the three views out.
Edit #2
Muthukrishnan's answer made me realize that you could solve this problem by simply removing the chain from your views. If you delete the app:layout_constraintBottom_toTopOf="#+id/news_title1" constraint from your ImageView, that will break the chain and now the vertical margins aren't shared.

Thanks to the great starter by Ben P, I managed to figure out a solution. There are three(plus one weighed) chaining styles available in ConstraintLayout. According to this great tutorial the chaining styles are explained as:
Spread: The views are evenly distributed. E.g.
app:layout_constraintHorizontal_chainStyle=”spread”
app:layout_constraintVertical_chainStyle=”spread”
Spread inside: The first and last view are affixed to the constraints on each end of the chain and the rest are evenly distributed. E.g.
app:layout_constraintHorizontal_chainStyle=”spread_inside”
app:layout_constraintVertical_chainStyle=”spread_inside”
Packed: The views are packed together (after margins are accounted for). You can then adjust the whole chain’s bias (left/right or up/down) by changing the chain’s head view bias. E.g.
app:layout_constraintHorizontal_chainStyle=”packed”
app:layout_constraintVertical_chainStyle=”packed”
Weighted: When the chain is set to either spread or spread inside, you can fill the remaining space by setting one or more views to “match constraints” (0dp). By default, the space is evenly distributed between each view that's set to "match constraints," but you can assign a weight of importance to each view using thelayout_constraintHorizontal_weight and layout_constraintVertical_weight attributes. If you're familiar with layout_weight in a linear layout, this works the same way. So the view with the highest weight value gets the most amount of space; views that have the same weight get the same amount of space.
spread is the default chaining style. I changed it to spread_inside so that the first and last views are affixed to the constraints on each end of the chain(hence obeying the margins provided). The xml now looks like:

android button same height as textview

I am struggling creating the UI for a list item which should look like this:
I am trying to build a similar layout for my list items like in the picture above. However, I am stuck, because I don't exactly know, how to nest the views so the sell-buttons has the same height as both textviews.
If I use the RelativeLayout than I cannot use the layout_weight attribute anymore which position the views evenly horizontally on the screen.
However, if I use the LinearLayout than I cannot use the relative-attributes like alignTop and so on. I am trying to nest the views in a way so I can achieve this, however I am failing so far... (sry for my poor english skills)
This is what I have so far, however I still cannot get the desired result:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="80dp"
android:padding="16dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="45dp">
<TextView
android:id="#+id/productname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:text="Google Pixel" />
<TextView
android:id="#+id/price"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/productname"
tools:text="699$" />
<TextView
android:id="#+id/quantity_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
tools:text="Quantity" />
<TextView
android:id="#+id/quantity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/quantity_textview"
android:layout_centerHorizontal="true"
tools:text="31" />
</RelativeLayout>
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="45dp"
android:layout_alignParentRight="true"
tools:text="SELL"
android:layout_alignParentTop="true" />
</RelativeLayout>

I'd recommend ConstraintLayout. This will allow you to set the top of the button to be constrained to the top of first text view, the bottom of the button to be constrained to the bottom of the second text view, and maintain the even distribution left to right with a horizontal chain.
Here's a an example I just threw together for funsies:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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">
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_marginTop="0dp"
android:text="TextView"
app:layout_constraintHorizontal_chainStyle="spread_inside"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="#+id/textView4"
app:layout_constraintTop_toTopOf="#+id/textView4"
tools:text="Google Pixel" />
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="0dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="#+id/textView5"
app:layout_constraintLeft_toLeftOf="#+id/textView2"
app:layout_constraintRight_toRightOf="#+id/textView2"
tools:text="6995" />
<TextView
android:id="#+id/textView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:text="TextView"
app:layout_constraintLeft_toRightOf="#+id/textView2"
app:layout_constraintRight_toLeftOf="#+id/button2"
app:layout_constraintTop_toTopOf="parent"
tools:text="Quantity" />
<TextView
android:id="#+id/textView5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="32dp"
android:text="TextView"
app:layout_constraintLeft_toLeftOf="#+id/textView4"
app:layout_constraintRight_toRightOf="#+id/textView4"
app:layout_constraintTop_toBottomOf="#+id/textView4"
tools:text="31" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="0dp"
android:layout_marginRight="8dp"
android:layout_marginTop="0dp"
android:text="Button"
app:layout_constraintBottom_toBottomOf="#+id/textView5"
app:layout_constraintLeft_toRightOf="#+id/textView4"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="#+id/textView4"
tools:text="Sell" />
</android.support.constraint.ConstraintLayout>
This gives you this layout in the preview:
And this is what the preview looks like showing the constraints. You can see the button being constrained to the two views (dashed lines), and the chain across the "Google Pixel" label, the "Quantity" label, and the button that keeps everything evenly distributed.
Note that if you want the button to be smaller to shrink down to match the bottom of the second text view, you have to set the button's minHeight attribute to 0. You'll probably also have to replace the default background of the button if you want pixel-perfect alignment of the top and bottom as the default background drawable has some built-in padding.
Hope that helps!

Try using Frame Layout, with it you will be able to align your views according to your need.
Or you can use a listview with a custom adapter for creating this kind of view. You can refer to this link
