I'm making xml of list-adapter item using Framelayout in Android Studio and I want to make it like pic1.
pic1
But I think it doesn't work. Because I can't bring product name or price in front of product image. And it works like this pic2.
pic2
I know that textView(id:price) would be the most recent child on top of the stack but it doesn't work.

I think it's because you have set android:elevation in your first ImageView. You either need to set a higher elevation for your TextViews, or remove the elevation if it's not necessary.

ConstraintLayout: How to center a text between two buttons of varying sizes

I'm making a dialog with a header that contains a "Cancel" button, a title and finally a "Save" button. See image. The title is constrained between the buttons. However, when one of the buttons are longer than the other the title moves to one side as it is told to stay in the middle between the buttons.
How can I make the title view be centered below the drag handle and at the same time let it expand all the way to the buttons without overlapping them?
Thanks!

I just implement the same functionality on three buttons that align horizontal and don't overlap each other.
Please create views in the same way below implementation.
<Button
android:id="#+id/btnExit"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="#dimen/dp_1"
android:background="#drawable/bluebtn_gradient_rectangle"
android:text="#string/exit"
android:textColor="#android:color/white"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintEnd_toStartOf="#+id/btnMemoryPreview"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/tvFill" />
<Button
android:id="#+id/btnMemoryPreview"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="#dimen/dp_1"
android:background="#drawable/bluebtn_gradient_rectangle"
android:text="#string/user_memory_preview"
android:textColor="#android:color/white"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/UserMemoryWrite"
app:layout_constraintStart_toEndOf="#+id/btnExit"
app:layout_constraintTop_toBottomOf="#+id/tvFill" />
<Button
android:id="#+id/UserMemoryWrite"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="#dimen/dp_1"
android:background="#drawable/bluebtn_gradient_rectangle"
android:text="#string/rfid_write"
android:textColor="#android:color/white"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/btnMemoryPreview"
app:layout_constraintTop_toBottomOf="#+id/tvFill" />

this is the only hack where you can set title without overlapping in centre of the screen
make one temp button same as long button in invisible mode

android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="long cancel"

</androidx.constraintlayout.widget.ConstraintLayout>
EDIT
this is another way, but this will be a mess when you have a very large title
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button

app:layout_constraintTop_toTopOf="parent" />
<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="save"
app:layout_constraintLeft_toRightOf="#id/txt"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView

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

android:gravity="center"
android:padding="#dimen/_10sdp"

app:layout_constraintTop_toTopOf="parent" />
<androidx.constraintlayout.widget.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5" />
</androidx.constraintlayout.widget.ConstraintLayout>
Edit
if you know max length of long cancel button you can set app:layout_constraintWidth_percent to TextView based on that button width
<TextView
android:id="#+id/txt"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#color/black"
android:gravity="center"
android:padding="#dimen/_10sdp"
android:text="title dfgfd gdg dfgdfg dfgdfg fdgfdfgd fgddf dfgdgdfgdfg dfg dfgfdg df"
android:textColor="#color/white"
app:layout_constraintLeft_toRightOf="#id/guideline"
app:layout_constraintRight_toLeftOf="#id/guideline"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintWidth_percent="0.4" />

Ok, so inspired by some of your answers I started looking at guidelines. The idea was to use two guidelines, one on each side of the view, and set the distance from the parent to the guideline as the width of the biggest button plus any margin. Final code looks like this:
val biggestWidth = if (cancelButton.width > saveButton.width) {
cancelButton.width + cancelButton.marginStart
} else {
saveButton.width + saveButton.marginEnd
}
guidelineRight.setGuidelineEnd(biggestWidth)
guidelineLeft.setGuidelineBegin(biggestWidth)
The title is centered between the two guidelines.
Note that this width calculation must happen after the view has been laid out. Use view.doOnLayout { } and call your calculation from there.

Your drag handle seems to be at the center of the layout. So you can relate the title to left and right of the parent instead buttons. But still overlapping could be possible if title and cancel button text is lengthy.

You can center the title with respect to the drag handle but then cannot expand the TextView between cancel and save button. I think both cannot be done simultaneoulsy.
You can use the below code to center the title w.r.t the drag handle
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:textAlignment="center"
app:layout_constraintEnd_toEndOf="#id/view"
app:layout_constraintStart_toStartOf="#id/view"
app:layout_constraintTop_toBottomOf="#id/view" />
<Button
android:id="#+id/cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="cancel"
android:textSize="#dimen/sp_16"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toStartOf="#id/title"
app:layout_constraintTop_toBottomOf="#id/view" />

app:layout_constraintStart_toEndOf="#id/title"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/view" />
</androidx.constraintlayout.widget.ConstraintLayout>

TextView
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
Cancel button
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toStartOf="#id/your_text_view_id"
Save button
app:layout_constraintStart_toEndOf="#id/your_text_view_id"
app:layout_constraintEnd_toEndOf="parent"
That way your buttons can expand freely without overlapping the text at the centre.

Remove Constrainsts button to textView and set TextView Constraints to left and right of layout.

How to add textview to the left side of the button in android

I'm developing the Quiz application in android and I have to display options A, B, C, D inside the button on the left side.
So I know one way, which can be setting the image by drawableLeft property of the button. But putting the four images is not so good.
So I want to know that if there is any other way of doing this may be setting textview inside the button or some other way?
Here is my xml code:

Here is the output:

Yes you can add textview at left of the button by giving it an elevation. Set constraints of textview : top to the top of button, start to the start of button and bottom to the bottom of button. And then add elevation, so that textview will be displayed above the button.

Just use LinearLayout instead of a button,set gravity to left, set the option first (A,B,C,D) and then the text view with an answer instead.
No difference visible since you are using custom background for the buttons.
Don't forget to add an OnClickListener() to the new LinearLayout button.

How to center align views in Android layout

I am trying to build the following layout on Android:
As indicated by the dotted lines:
- The two TextViews should be left aligned.
- The ImageView should be center aligned with the title TextView
The labels should be anchored relative to the parent and each other as indicated in the sketch.
I have tried to implement this using ConstrainedLayout which gets me pretty far. But the tricky part is the alignment of image and title.
I would need an attribute like layout_constraintCenter_toCenterOf which unfortunately does not exist.
EDIT: ### removed hard-coded height ###
There was an unwanted hardcoded height in my code (marked in example below). After removing that it works fine for me.
But the question stands: What is the 'right' way to center-align views?
My solution feels like a hack.

I have tried to work around by aligning top and bottom which looks right in the preview but causes glitches in the real app:

app:layout_constraintTop_toTopOf="#+id/image1"
Maybe ConstrainedLayout is the wrong tool for the job altogether.

Dynamically set the view width using constraint layout

I am new to ConstraintLayout, Below is my xml file in this I am trying to achieve my Textview width dynamically. If my #+id/btn1 visibility is gone then TextView (#+id/tv1) should expand to full width. Please suggest what approach I should use to solve this problem with in the same way.
<?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="match_parent"
android:layout_margin="#dimen/default_gap"
app:layout_anchorGravity="right">
<TextView
android:id="#+id/tv1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="First thing first, if you have a min SDK lower than 17, you can now shift to using only start and end attribute and don’t repeat yourself for right and left"
app:layout_constraintEnd_toEndOf="#+id/guideline_center"
app:layout_constraintStart_toStartOf="parent" />
<Button
android:id="#+id/tv_cur_type"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RS"
app:layout_constraintTop_toBottomOf="#+id/tv1" />
<android.support.constraint.Guideline
android:id="#+id/guideline_center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5" />
<Button
android:id="#+id/btn1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:visibility="visible"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/guideline_center" />
<TextView
android:id="#+id/tv2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Payment Mode"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/guideline_center"
app:layout_constraintTop_toBottomOf="#+id/btn1" />
</android.support.constraint.ConstraintLayout>
Below is the screenshot,enter image description here how it's looks now

Remove textview endconstraint and connect to button & make horizontal chain between button & textview then textview takes fullwdith when button view is gone.
Try this
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="20dp"
android:layout_marginBottom="20dp"
android:layout_marginEnd="21dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="21dp"
android:layout_marginStart="20dp"
android:layout_marginTop="20dp"
app:layout_anchorGravity="right">
<TextView
android:id="#+id/tv1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"
android:text="First thing first, if you have a min SDK lower than 17, you can now shift to using only start and end attribute and don’t repeat yourself for right and left"
app:layout_constraintEnd_toStartOf="#+id/btn1"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/tv_cur_type"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RS"
app:layout_constraintTop_toBottomOf="#+id/tv1" />
<android.support.constraint.Guideline
android:id="#+id/guideline_center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5" />
<Button
android:id="#+id/btn1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:visibility="visible"
app:layout_constraintBottom_toTopOf="#+id/tv2"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toEndOf="#+id/tv1"
app:layout_constraintTop_toTopOf="parent"
/>
<TextView
android:id="#+id/tv2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:text="Payment Mode"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/guideline_center"
app:layout_constraintTop_toBottomOf="#+id/btn1" />
</android.support.constraint.ConstraintLayout>
