Add foreground within borders

I have a recylcerview with borders, and i want to add an animation to the bordered area only, how do i add it? I want to add android:foreground="?attr/selectableItemBackground" such that when row is clicked, only the bordered area displays the animation, not the whole row
Recycler View
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

You could use the ripple tag instead of layer-list to acheive the required behaviour.
Note: This will work only for API 21+(Lollipop).
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
tools:targetApi="lollipop" android:color="?colorControlNormal">
<item
android:left="8dp"
android:right="3dp"
android:top="8dp"
android:bottom="2dp">
<shape android:shape="rectangle">
<solid android:color="#CBAAAAAA"
android:width="1dp"/>
<corners android:radius="5dp" />
</shape>
</item>
<item
android:left="5dp"
android:right="5dp"

custom seekbar not showing

I created a custom seekbar.
It looks normal on the Android emulator, but only the thumb is visible on the actual device.
If you subtract the android:progressDrawable or android:thumb attributes from the properties of the seekbar in the xml file, the thumb or progressbar will look normal.
The seekbar is not visible properly when you apply two properties at the same time.
here is source.

Shadow text view in Android

I am trying shadow text view like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="top|center"
android:background="#drawable/gradient">
<TextView
android:layout_width="300dp"
android:layout_height="50dp"
android:text="#string/ph"
style="#style/TextBox"
android:textSize="16sp"/>
</LinearLayout>
gradient.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<gradient
android:endColor="#FFFFFF"
android:startColor="#FFFFFF"
android:type="linear"
android:centerColor="#E3F2FD"
android:angle="90">
</gradient>
</shape>
</item>
This code can't get my design. Is it possible to textview like my picture?

Here i tried to create same shadow as your requirement which will look like this. I know the shadow color is not blur as u want
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#drawable/shadow"
android:orientation="vertical"
android:paddingBottom="5dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/rectangle_shape"
android:padding="10dp"
android:text="Phone Number" />
</LinearLayout>
drawable/shadow.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#220000ff" />
<corners android:radius="20dp" />
</shape>
drawable/rectangle_shape.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FFFFFF" />
<corners android:radius="20dp" />
</shape>

make xml backround_with_shadow and paste this code-
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item >
<shape
android:shape="rectangle">
<solid android:color="#87ceeb" />
<corners android:radius="5dp"/>
</shape>
</item>
and set xml as background of layout
<item android:right="1dp" android:left="1dp" android:bottom="2dp">
<shape
android:shape="rectangle">
<solid android:color="#android:color/white"/>
<corners android:radius="5dp"/>
</shape>
</item>
</layer-list>

Half circle shape not work

I try to create half circle background, in development IDE preview it works, but when I launch in emulator it doesn't work.
Here is my shape code :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:height="50dp">
<shape>
<solid android:color="#color/colorAccentDark" />
</shape>
</item>
<item android:top="-500dp" android:bottom="0dp" android:left="-100dp" android:right="-100dp">
<shape>
<corners android:radius="500dp" />
<solid android:color="#color/colorAccentDark" />
</shape>
</item>
</layer-list>
And here is my layout code :
<?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">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_profile"
android:layout_weight="1">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/profile_avatar"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/ic_default_avatar"
android:layout_centerHorizontal="true"
android:layout_marginTop="50dp"/>
<TextView
android:id="#+id/profile_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/profile_avatar"
android:layout_marginTop="20dp"
android:textColor="#color/neutralWhite"
android:textStyle="bold"
android:textSize="18sp"
android:text="Avatar Ang"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="4.04">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello Android!"/>
</RelativeLayout>
</LinearLayout>
Maybe any other tweak to handle that?
Thank you

you can try this :
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#900021df"/>
<size
android:width="10dp"
android:height="5dp"/>
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"/>
</shape>
it gives this shape:

curve_toolbar_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle"/>
</item>
<item
android:bottom="0dp"
android:left="-100dp"
android:right="-100dp"
android:top="-80dp">
<shape android:shape="oval">
<solid android:color="#color/colorPrimary" />
</shape>
</item>
</layer-list>
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="0dp"
android:layout_height="?android:attr/actionBarSize"
android:background="#drawable/rounded_corner"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0">
</android.support.v7.widget.Toolbar>
</android.support.constraint.ConstraintLayout>

You cannot create a semicircle from xml. but you could achieve what you are looking for using a circle with appropriate margin & padding.
You can use a circle shape .xml file.
Create a fixed sized circle like this:
Example:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval"
android:useLevel="false" >
<solid android:color="#006AC5" />
<size
android:height="50dp"
android:width="50dp" />
</shape>

Try this. Remove the gradient part then it will look like same as you want.
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#00B0EA" />
</shape>
</item>
<item
android:bottom="400dp"
android:left="-100dp"
android:right="-100dp"
android:top="-200dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<gradient
android:angle="90"
android:endColor="#65FFFFFF"
android:startColor="#65FFFFFF" />
</shape>
</item>
<item
android:bottom="402dp"
android:left="-100dp"
android:right="-100dp"
android:top="-280dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#FFFFFF" />
</shape>
</item>

Background.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FFFFFF" />
</shape>
</item>
<item
android:bottom="410dp"
android:left="-100dp"
android:right="-100dp"
android:top="-300dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#7181A1" />
</shape>
</item>
</layer-list>
Output like

You can try to use ShapeOfView.
<io.github.florent37.shapeofview.shapes.ArcView
android:layout_width="match_parent"
android:layout_height="300dp"
android:elevation="4dp"
app:shape_arc_height="20dp"

Rectangle Shape with Arrow using XML

How to implement this shape of Departments header using shape and xml without 9-patch ?
I mean rectangle with arrow on the left.
My code snippet:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="1px"
android:left="#dimen/edittext_border"
android:right="#dimen/edittext_border"
android:top="#dimen/edittext_border">
<shape android:shape="rectangle">
<stroke
android:width="#dimen/edittext_border_width"
android:color="#color/menu_divider" />
<solid android:color="#color/background" />
<corners android:radius="4dp" />
</shape>
</item>
</layer-list>

if you are looking for someting like this, try the following code..
Make a xml arrow_shape in your drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<rotate android:fromDegrees="45" android:toDegrees="45"
android:pivotX="-40%" android:pivotY="87%" >
<shape android:shape="rectangle" >
<stroke android:color="#c6802a" android:width="10dp"/>
<solid android:color="#c6802a" />
</shape>
</rotate>
</item>
</layer-list>
Make a xml rectangle_shape in your drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<solid android:color="#B2E3FA" />
</shape>
</item>
In your main xml file
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:gravity="center"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.stpl.myapplication.MainActivity">
<RelativeLayout
android:id="#+id/arrow"
android:layout_width="30dp"
android:layout_height="30dp"
android:background="#drawable/arrow_shape"
android:rotation="270" />
<RelativeLayout
android:id="#+id/rectangle"
android:layout_width="150dp"
android:layout_height="50dp"
android:background="#drawable/rectangle_shape"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:android="http://schemas.android.com/tools" />
</LinearLayout>

A solution with a gradient:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:width="2dp" android:height="2dp"
android:top="4dp" android:left="3dp">
<rotate android:fromDegrees="45"
android:pivotX="0"
android:pivotY="0">
<shape>
<solid android:color="#D83945"/>
</shape>
</rotate>
</item>
<item android:width="50dp" android:height="11dp" android:left="3dp">
<shape>
<gradient
android:startColor="#D83945"
android:endColor="#F9700C"
/>
<corners
android:radius="2dp"
/>
</shape>
</item>
</layer-list>
The final result is:
