I'm using my android phone with 5'5 screen size and still cut out my
my imgView_icon and my btnConnectFacebook. I can't see them on my screen.
what's wrong then in my XML?

please let me know if I need to upload the images for a better perspective of my problem.
maybe because my images are big?
if my images are big how can I proportionally set a width and height for my photos
where it can dynamically adjust to its parent size or screen size?
This may happen because you are using android:layout_height="wrap_content"
on your imageView.
If your image is too large your layout won't be responsive anymore (because 900dp image, for example, will take all the screen size while using wrap_content).
how can i proportionally set a width and height
You can tell your image or any other view what size to be in precents like this:
<Button
android:id="#+id/button"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintWidth_percent="0.5" //50% of the screen Width
app:layout_constraintHeight_percent="0.5" //50% of the screen Height
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
I think below solution might work for you.
Remove app:layout_constraintBottom_toTopOf="#+id/tvHeaderText" from ImageView Icon
and Remove app:layout_constraintTop_toBottomOf property from all other views.
Hope it will solve your issue. :)

I am trying to set up a layout for a counting app, which has a large circular button slightly above the centre of the screen and a counter display below it. I'm having trouble keeping the circle circular, entirely on the screen, and not overlying the other view in all situations.
The setup I'm currently using is a ConstraintLayout with two TextViews. The button TextView uses an xml oval as its background, and is set to be circular with the "layout_constraintDimensionRatio" attribute set to one. In portrait mode the width is set to 80% of the available space, and all is well when the screen is fairly standard in normal use.
The problem occurs if the available screen dimensions for the app are more square so that the vertical dimension is smaller than the horizontal dimension. In this case the width is still set first so my circle covers the other view or partially slips off screen.
Currently in the landscape layout I have the timer off to one side. Ideally in the landscape layout I would keep the button centred and the counter to the right, but to stop increasing the size of the button if there is not enough space for the timer.
I think that ideally I would set the layout up to check whether the horizontal or the vertical space is shorter initially, then set the smaller dimension first. Is this possible? Or perhaps is there a better approach to achieving my desired layout?
Any help would be really appreciated,
Thank you,
Katie

As you suggest, the primary issue with your layout is the percentage width/height set at 80% and driving the rest of the layout. You are losing control of the circle height and nothing keeps it from growing to cover other views.
Take a look at ConstraintLayout chains. They are a powerful tool and will let you tie your views together so they don't trounce one another. They will help you solve the overlay problem.
You will still want to set the width of the circle to 80% of the width or height depending on the orientation of the device. I assume that you want the side margins to be such that the circle can be 80% of the view but will allow the circle to be smaller if it needs to fit the screen and not overlap the other views. One way to do this is to define two Space widgets that are 10% of the layout width and 10% high. Place one in the upper left corner of the layout and the other in the lower right. Constrain the circle to these Space widgets on the left, top and right. Place the circle in a vertical chain with the TextView below.
Here is a mock up of what it would look like. You will have to work with your layout to get it right, but these are some concepts that should help. (Is seems to me that this can also be done without the Space widgets, but that solution is not occurring to me right now. I'll post back if it dawns on me.)
The XML follows the GIF.

I am trying to display an image view next a label and a text box. The end result should look like this:
The height of the image view should be the same as whatever space the label and the text box take up and the width should be the same as the height so it is a square.
I have looked at this question to make an image view with equal width and height.
I have also looked at this other question which is similar to mine but using weightSum and layout_weight made the image view take up too much space or become distorted. I have also tried combining answers from the two questions but nothing worked.
You can achieve this very simply using ConstraintLayout:
<?xml version="1.0" encoding="utf-8"?>

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHeight_percent="0.3"
app:layout_constraintHorizontal_bias="1.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageView

app:layout_constraintDimensionRatio="1:1"
app:layout_constraintBottom_toBottomOf="#+id/button2"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#+id/button2"
android:background="#color/colorAccent"/>
<TextView
android:id="#+id/textView3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:elevation="6dp"
android:layout_marginLeft="8dp"

This will look like this
The important attributes:
To make your image square:
app:layout_constraintDimensionRatio="1:1"
To make your views responsive:
app:layout_constraintWidth_percent
app:layout_constraintHeight_percent
Together with:
android:layout_width="0dp"
android:layout_height="0dp"
To make your views over the container so it looks like they are inside it (in this example I have used a button but feel free to use any kind of view)android:elevation="6dp"
I wonder how to implement the following design in Android xml. The contents will have height wrap-contents with the most priority, and it could even fill the whole screen if there are enough contents. The image above it should fill up the remaining height - however it also has a limited max-height of 160dp. It seems if I use layout-weight or match-parent, the max-height param does not work anymore. Is there a way to do this in the xml? Or do I have to do it in the Java file programmatically? Thanks.
try something like this:
I'm using two textView just for test

those are the important lines

I have an imageview that I will place different images.
This images can have many sizes like 200x200 200x400 400x200...
Above imageview I have an adview and below this imageview I need 4 buttons.
The problem is, I'd like the image be below adview, but stop jumping position when ad loads. It goes down when an ad loads, I'd to stop this move, make the image fix, but above the adview.

TL;DR
The fastest solution would be to change your ad view android:layout_height="wrap_content" into android:layout_height="fixed size" so your ad view will have a single height and won't change because of its wrap_content attribute (If your ad view is not loaded you can think of wrap_content as height of 0 and only after its loaded it will have height, thus the layout jump).
Why is it bad?
your layout won't be responsive.
How to fix?
Read the answer below.
Long but better answer:
You can use guidelines with app:layout_constraintGuide_percent=".2" to tell your guideline to be at the top of your screen (80%) and constraint your ad view to your guideline - this way your layout will won't jump (it will have its space to load into).
Another thing, different phones got different screen size, in your layout you are using fixed size on your view (fixed size is 50dp for example) and the result is that what may look good on one screen (your android studio preview screen) will not look good on another screen (your actual phone).

Here is how it will look (I am adding a screenshot from the layout editor for better understanding ConstaintLayout)
Some extra information:
ConstraintLayout is not meant to have nested view groups (in your case you have LinearLayout inside constraintlayout).
ConstraintLayout allows you to create large and complex layouts with a flat view hierarchy (no nested view groups). It's similar to RelativeLayout in that all views are laid out according to relationships between sibling views and the parent layout, but it's more flexible than RelativeLayout and easier to use with Android Studio's Layout Editor.
You can Use ConstraintLayout with guidelines and Chains to support different screen sizes, you won't have to use fixed sizes on your views and you will be able to use a single layout to support different screen size.
Give the adview or it's surrounding layout a minimum height equal to the smart banner content in your case likely 90px.
It's jumping because with no content loaded your wrap_content height = 0, then it gets a new height of x, so your imageview shifts down x.
I've been experimenting with ConstraintLayout, is there a way to set the max width of a view to a percentage of the parent (and a height of match constraint and dimension ratio of 1:1)?
Here is the code without using max width:
<?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:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/frameLayout3"
android:layout_width="0dp"
android:layout_height="259dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:background="#android:color/black"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintStart_toEndOf="#+id/imageView"
app:layout_constraintTop_toTopOf="parent"/>
<ImageView
android:id="#+id/imageView"
android:layout_width="0dp"
android:layout_height="0dp"
android:src="#android:drawable/ic_menu_add"
app:layout_constraintBottom_toBottomOf="#+id/frameLayout3"
app:layout_constraintDimensionRatio="1:1"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_percent="0.3"/>
</android.support.constraint.ConstraintLayout>
This is the result:
Tablet:
Phone:
I achieved the max width percentage using two attributes:
app:layout_constraintWidth_max="wrap"
app:layout_constraintWidth_percent="0.4"
Example:
<TextView
android:id="#+id/textView2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:text="Helo world"
android:textAlignment="viewStart"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_max="wrap"
app:layout_constraintWidth_percent="0.4" />
The text width will increase to 40% of parent and then wrap if the content exceeds that.
If I'm understanding your problem right then You're almost there. I think you're giving frameLayout static height that's why it is not giving the appropriate result on tablet.. because you set the height according to phone preview. What you need to do is make the height of frameLayout relative to imageView.. so when imageView grows in size the frameLayout also grows with it.
I think you should do 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"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageView"
android:layout_width="0dp"
android:layout_height="0dp"
android:src="#android:drawable/ic_menu_add"
app:layout_constraintDimensionRatio="1:1"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_percent="0.3" />
<FrameLayout
android:id="#+id/frameLayoutTwo"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#android:color/black"
app:layout_constraintBottom_toBottomOf="#+id/imageView"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/imageView"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
I checked and this gives the same result in phone and tablet. Correct me if I misunderstood your problem.
No, there is not. I think we should file a feature request. I am pretty sure that PercentRelativeLayout also does not have this feature. (This answer is accurate for ConstraintLayout 1.1)
You can set a LinearLayout or other ViewGroup as exact percent width and place your wrap_content view inside this layout.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/image_place_holder"
android:layout_width="0dp"
android:layout_height="0dp"
android:scaleType="centerCrop"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<!-- This LinearLayout will have exact 80% of parent width-->
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_percent="0.8">
<!-- This MaterialCardView will get a wrap_content width,
with a max width of his parent LinearLayout, which is 80% -->
<com.google.android.material.card.MaterialCardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="#dimen/half_activity_horizontal_margin"
android:layout_marginTop="#dimen/half_activity_vertical_margin"
android:layout_marginEnd="#dimen/half_activity_horizontal_margin"
android:layout_marginBottom="#dimen/half_activity_vertical_margin"
android:backgroundTint="?attr/colorPrimary">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:paddingStart="#dimen/half_activity_horizontal_margin"
android:paddingEnd="#dimen/half_activity_horizontal_margin"
android:text="Lorem ipsum"
android:textAppearance="?attr/textAppearanceCaption" />
</com.google.android.material.card.MaterialCardView>
</LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
