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"

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

</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">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/phase_banner"

android:scaleType="centerCrop"
android:adjustViewBounds="true"/>

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.

How to make a ripple effect over a linear layout, without overriding the background color on its children?

I have a LinearLayout that looks like this.
I want each row to be clickable. The LinearLayout code for a row looks like this:
<LinearLayout
style="#style/home_menu_item_container"
android:id="#+id/home_menu_acronyms_button"
>
<ImageView
style="#style/home_menu_item_left"
android:background="#color/greyLight"
/>
<TextView
style="#style/home_menu_item_right"
android:text="#string/home_menu_option_2"
android:background="#color/grey"
/>
</LinearLayout>
How can I add a ripple effect that expands over the entire row (parent) - not just one child view in the row? The tricky part here is to let the ripple go over the two colored row.

So far, I found out the easiest way to do so is define a <ripple> in your drawable and then set the background of the LinearLayout to this drawable resource.
Define your drawable-v21/item_selector.xml
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/your_background_color">
<item android:id="#android:id/mask"
<!--color here doesn't matter-->
android:drawable="#android:color/white" />
</ripple>
Set the background of your LinearLayout to drawable/item_selector.
<LinearLayout
style="#style/home_menu_item_container"
android:background="#drawable/item_selector"
android:id="#+id/home_menu_acronyms_button" >
...
</LinearLayout>
Besides, if you don't have your own background color, then there is no need to define a item_selector at all. You can simply define background as android:background="?android:attr/selectableItemBackground" for your LinearLayout.

It is a little bit complicated for that what you need but I don't think there is another way,...
You need to put your ImageView's into a ListView so that every ImageView is a ListItem and then you can set the ripple but you also need to set drawSelectorOnTop="true" otherwise it won't work correctly

I too faced this problem, finally found a simple solution
In linear Layout just add android:clickable="true";
and set background with ur ripple effect as
android:background="#drawable/ripple_effect"
code:
<LinearLayout
android:clickable="true"
android:background="#drawable/ripple_effect"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- Add your child views here -->
</LinearLayout>
add ripple_effect.xml in drawable
ripple_effect.xml:
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:color="#f87d05c2"
tools:targetApi="lollipop">
<item android:id="#android:id/mask">
<shape android:shape="rectangle">
<solid android:color="#f87d05c2" />
</shape>
</item>
</ripple>

<RelativeLayout
android:id="#+id/rll_privacy_policy"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="?android:attr/selectableItemBackground"
android:orientation="vertical">
<TextView
android:id="#+id/txt_privacy_policy"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/layout_margin_16"
android:text="#string/privacy_policy"
android:layout_centerVertical="true"
android:textColor="#color/link_acc"
android:textSize="#dimen/txt_title_20" />
</RelativeLayout>

Another option is to make the ripple's background color transparent. This way only the ripple can be seen. The ripple's xml file (in your drawable-v21/ folder) is thus:
<-- Ripple in some ghastly color, like bright red so you can see it -->
<ripple
xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/red"
>
<!-- background color uses a transparent mask set to full #ffffff (white) -->
<item
android:id="#android:id/mask"
android:drawable="#android:color/white"
/>
Note that if you are supporting pre-lollipop devices, you need to have a dummy file with the same name in your drawable/ folder. An empty selector is sufficient for that file. And remember that those older devices will not ripple.

answer above dont work for me,
here is my solution:
ripple.xml:
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="?android:colorControlHighlight">
<item android:id="#android:id/mask">
<shape android:shape="rectangle">
<solid android:color="?android:colorAccent" />
</shape>
</item>
</ripple>
list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
>
...put het your design
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/ripple" />
</FrameLayout>

Inset drawable not working as described in documentation

As described on Android Developer site:
A drawable defined in XML that insets another drawable by a specified
distance. This is useful when a View needs a background that is
smaller than the View's actual bounds.
http://developer.android.com/guide/topics/resources/drawable-resource.html#Inset
Instead of just moving the background and leaving the content in place in my case the inset is also moving the TextView.
This is the layout:
<?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:background="#android:color/white"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg_inset"
android:orientation="horizontal" >
<TextView
android:id="#+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some text"
android:textSize="23sp" />
</LinearLayout>
This is the bg_inset drawable
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="#android:color/darker_gray"
android:insetLeft="100dp" />
And this is the result I get:

By default, setting a background drawable also applies that drawable's padding to the view. Set the padding explicitly if you don't want it to match the background drawable.

Try to use shape with left-padding instead of inset:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#android:color/darker_gray"/>
<padding android:left="100dp"/>
</shape>

Another option: if you want to use DP instead of PX, try my suggestion below. From my experience, InsetDrawable only works with pixels, which I find... unhelpful. To be honest, I am not happy with this solution, but hey, it works.
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="10dp"
android:drawable="#drawable/image_placeholder"
android:top="10dp" />
</layer-list>

Layout with buttons inside Google Maps

I want to put a Layout with Buttons inside Google Maps with a gradient background as in this app:
i have done many combinations but they not works. How I can to make it?

it just put a maps and button inside relative layout it works for me
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent">
<com.google.android.gms.maps.MapView
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/textView_for_welcome"
android:apiKey="#string/live_key_for_map"
android:clickable="true" >
</com.google.android.gms.maps.MapView>
<LinerLayout
android:id="#+id/textView_for_welcome"
android:layout_width="fill_parent"
android:layout_height="80dp"
android:background="#drawable/backgroud_layout"
android:gravity="center"
>
----inside put all ur Views ----
</LinerLayout>
</RelativeLayout>
also use gradient background for button (or any layout) u want but important thing is u must specify next to map
You can use backgroud_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#AA474946"
android:endColor="#FFFFFFFF"
android:angle="270"/>
<corners android:radius="5dp" />
</shape>
to drawable folder
use FF-Alpha FF-Red FF-blue FF-Green
