Image view not clipped inside constraint layout with drawable shape background

This is my drawable shape
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<corners android:topLeftRadius="20dp"
android:topRightRadius="20dp"
android:bottomLeftRadius="20dp"
android:bottomRightRadius="60dp"/>
<solid android:color="#color/primary_blue"/>
</shape>
My layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="296dp"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:clipChildren="true"
android:clipToPadding="false"
android:background="#drawable/bg_shape_bottom_right_curved"
app:cardPreventCornerOverlap="false"
android:outlineProvider="background"
android:layout_height="198dp">
<ImageView

android:adjustViewBounds="true"/>
</LinearLayout>
The image keeps on being square and not getting the shape of drawable. Please help
When i add shape to the layout its showing the shape . But when i set image src its showing sqaure image , when setting background, it getting into right shape. But i need to load image from glide . so i need to make it work with src

Unfortunately, your background drawable does not qualify for clipping. From Clip Views:
Only rectangle, circle, and round rectangle outlines support clipping, as determined by the Outline.canClip() method.
Your background drawable does not qualify as a rounded rectangle but is implemented internally as a path (I believe). This is one reason clipping is failing for you.
Let's create a simple rounded rectangle drawable:
simple_rounded_rectangle.bg
<shape android:shape="rectangle" >
<corners android:radius="30dp"/>
<solid android:color="#color/primary_blue"/>
</shape>
Also, let's modify the layout a little:
activity_main.xml
<LinearLayout
android:id="#+id/layout"
android:layout_width="400dp"
android:layout_height="198dp"
android:background="#drawable/simple_rounded_rectangle"
android:outlineProvider="background">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:src="#drawable/phase_banner" />
</LinearLayout>
We will also need to add some code to direct the view system to clip the view to the outline:
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val layout = findViewById<LinearLayout>(R.id.layout)
layout.clipToOutline = true
}
}
The main thing in this code is the line
layout.clipToOutline = true
which indicates that clipping should occur. There should be an XML attribute that does the same thing android:clipToOutline but there isn't below API 31. See the android:clipToOutline bug report.
Putting it altogether we see the following. (The image is one I supplied.)
If you use your drawable for the background, it will not be clipped for the reason I mentioned above.
You will need to fall back to a different method of clipping if you need asymmetric corners on your drawable. You may want to look at applications of clipPath. You will find information on how to do this if you do some online searching. I also suggest the Medium post Clipping and shadows on Android for other alternatives.
Take a look at the Material Components Library. MaterialCardView and ShapeableImageView may be useful.

This is your drawable shape.
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:topLeftRadius="20dp"
android:topRightRadius="20dp"
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
/>
<solid android:color="#color/primary_blue"/>
</shape>
Layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="400dp"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:clipChildren="true"
android:clipToPadding="false"
app:cardPreventCornerOverlap="false"
android:outlineProvider="background"
android:layout_height="198dp">

How to make image view with rounded edge at bottom with shadow

I want to make my ImageView curved at the bottom with shadow effect.
Similar to this image
But I don't have any idea about how to do this.
Whenever I search on Google or StackOverflow it shows me results related to curved corners but I want curved edge at bottom.

you can make shape use layer-list
for example,
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:left="-150dp"
android:right="-150dp"
android:top="-200dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#C72C2F" />
</shape>
</item>
</layer-list>
it show like this.
And then use this in background,
<?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=".MainActivity">
<LinearLayout
app:layout_constraintTop_toTopOf="parent"
android:background="#drawable/round"
android:elevation="30dp"
android:layout_width="match_parent"
android:layout_height="700dp"/>
</androidx.constraintlayout.widget.ConstraintLayout>
it make like this.
Also for make shadow effect, I use android:elevation it make shadow, and if you increase value, it can make more depth.
And obviously add image view for show images. I believe you can do this.

How to add a fully transparent to semi-transparent gradient in Android

I have a situation where I want to add an image view doing the same effect as this app
As you notice there is a drawable or something hiding the bottom side of the view adding a transparent gradient. How can I achieve the same effect?

Well, you can use fadingEdge attribute of the listView in your xml. Make a listView, then add items xml (images in particular as you've mentioned above).
android:fadingEdge="horizontal"
android:fadingEdgeLength="30dp"
android:fillViewport="false"
android:requiresFadingEdge="vertical"

Place this drawable in the bottom of your layout:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#FFFFFF"
android:endColor="#android:color/transparent"
android:angle="90" />
</shape>
Your layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white" >
<View
android:layout_width="match_parent"
android:layout_height="20dp"
android:background="#drawable/gradient"
android:layout_gravity="bottom"/>
</FrameLayout>

I think you can change alpha value of that image View. Go through
this and this for more details.

Custom RelativeLayout to have circular boundary

I have a requirement to show a View which need to have a circular boundary.
I know it can be done by Extending the RelativeLayout. But exactly dont know what all methods to override except constructors and what code changes I have to make for it to show circular boundary.
Updated question with Image.
So basically this is an animation.
and minutely the view goes out from screen from the circumference of the circle (And not as rectangular view).
So I have to create a circular view (Relative Layout) that is having child of these images.

Use android.support.v7.cardview and put a RelativeLayout as its child.
https://developer.android.com/reference/android/support/v7/widget/CardView.html
Note from the above link:
Due to expensive nature of rounded corner clipping, on platforms
before L, CardView does not clip its children that intersect with
rounded corners. Instead, it adds padding to avoid such intersection
(See setPreventCornerOverlap(boolean) to change this behavior).

i think you need to make any layout with rounded border. using below code for make layout rounded.
round.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item><shape>
<solid android:color="#color/list_row_bg" />
<corners android:bottomLeftRadius="4dp"
android:bottomRightRadius="4dp"
android:topLeftRadius="4dp"
android:topRightRadius="4dp" />
<stroke android:width="1dp" android:color="#color/header_bg" />
</shape></item>
</selector>
put this round.xml file drawable folder. and use as backgournd in your layout.
my_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="25dp" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/round" />
</LinearLayout>

how to create rounded corner videoview in android?

In my application, I want to display videoview as a rounded corners. I have tried placing videoview/surfaceview inside linearlayout with rounded corner set to linearlayout. but it does not work perfectly. I can not set rounded corner to videoview/surfaceview. I want to set view as below image:
Anyone have idea how to do this?

Not sure why there are so many bad answers when the solution is really simple (as long as you're min sdk > 21). Creating a shape and putting it overtop of the video won't work because you obviously want the background to be transparent to see the views behind it.
I found the answer here Android View Clipping. You just put the video view in a frame layout, add a rounded background to the frame layout, add an outline provider and clip the frame layout to the outline.
The background rounded_video_background:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#000000"/>
<corners android:radius="16dp" />
</shape>
The frame layout and video view inside of it:
<FrameLayout
android:id="#+id/video_view_container"
android:layout_width="90dp"
android:layout_height="120dp"
android:background="#drawable/rounded_video_background"
android:outlineProvider="background">
<VideoView
android:id="#+id/video_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
/>
</FrameLayout>
And the final step is clipping to the outline (didn't see a way to do it in xml so I did it programatically):
video_view_container.clipToOutline = true

Its worked for me,
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_gravity="center"
android:layout_width="match_parent"
card_view:cardCornerRadius="25dp"
android:layout_height="wrap_content">
<VideoView
android:id="#+id/video"
android:layout_width="match_parent"
android:layout_height="215dp" />
</android.support.v7.widget.CardView>

You can make it using a FramLayout & an XML drawable
FramLayout
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<VideoView
android:layout_width="match_parent"
android:layout_height="#dimen/dp_240"
android:layout_margin="#dimen/dp_24"/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rounded_corner_video_bg" />
</FrameLayout>
XML Drawable
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="#dimen/dp_24"
android:color="#color/md_white_1000" />
<corners android:radius="#dimen/dp_24" />
</shape>

You could try layering different views on top of each other to create the rounded corners you are looking for. Try placing four ImageViews over the VideoView in each corner, to achieve the desired rounded corners. I have had success using a RelativeLayout to accomplish this, but you could also try using a FrameLayout to hold the Views together.

It is directly not possible, but you can do this by draw a imageview on top of videoview and set an image having transparent from between and solid color in rounded shape on the corners.

Its simple,
1. Create a drawable with rounded corners as mentioned by #sunil kumar
2. Set that drawable to your layout as a background
3. When using that layout set layout(your layout item name).clipToOutline = true

This is XML code of rounded VideoView.
<androidx.cardview.widget.CardView
android:id="#+id/videoCard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="16dp"
android:layout_marginBottom="16dp"
app:cardCornerRadius="20dp"
card_view:cardBackgroundColor="#color/white">
<VideoView
android:id="#+id/relativeVideo"
android:layout_width="match_parent"
android:layout_height="225dp"
android:paddingTop="-10dp"
android:paddingBottom="-10dp" />
</androidx.cardview.widget.CardView>
Negative padding is important otherwise height of VideoView is smaller than cardview by half of cornerRadius in both top and bottom side. You can set height whatever you want but negative padding should be half of cardCornerRadius all the time. Purple in the image is a video preview, not related to xml.
Have a nice day!

put rounded.xml in your drawable folder and set on framelayout of video like android:background="#drawable/rounded.xml"
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#FFFFFFFF" />
<corners android:radius="7dp" />
</shape>

Create an xml file in drawable folder called shape_video.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners android:radius="6dp" />
</shape>
Change the radius according to your rqmnt and in the background attribute of your videoview, give
android:background="#drawable/shape_video"
