How to achieve custom shape match parent?

I created custom shape in XML:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
<shape android:shape="rectangle">
<size android:width="160dp"/>
<size android:height="30dp"/>
<solid android:color="#color/white"/>
<padding android:right="15dp"/>
<stroke android:width="1dp" android:color="#color/main_color"/>
<corners android:radius="15dp"/>
</shape>
</item>
<item
android:drawable="#drawable/down_arrow_red"
android:width="10dp"
android:height="6dp"
android:gravity="center|right"/>
</layer-list>
</item>
</selector>
Since match parent wasn't allowed while defining of width and height, I am worried how this shape will look like on different size screens. How to make this shape match parent screen? Thanks!

I think what you want to ask is about sizing.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<item>
<shape
android:layout_width="match_parent"
android:shape="rectangle">
<size android:height="30dp" />
<solid android:color="#color/white" />
<padding android:right="15dp" />
<stroke
android:width="1dp"
android:color="#color/teal_200" />
<corners android:radius="15dp" />
</shape>
</item>
<item
android:width="10dp"
android:height="6dp"
android:drawable="#android:drawable/arrow_down_float"
android:gravity="center|right" />
</layer-list>

Android custom radiobutton

I want to make custom radio button.I have created a drawable for normal(radio_normal) state.But I find it difficult to create a shape for checked state(radio_pressed).I have tried creating my desired way.But didn't work out well.I don't know if I have done it the right way.For checked state the shape should look like this.The outer border and the inner circle must be white in color.Can anybody help me with that?
radio_normal:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="ring"
android:useLevel="false">
<solid

</shape>
radio_pressed:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

android:layout_centerInParent="true"
android:layout_width="10dp"
android:button="#drawable/radio_bg"
android:layout_marginTop="100dp"

This is about as close as I can get you, hope it works on your side and that it helps :)

Let me know if this worked for you :)

Is this maybe what you were looking for ?

Reaction to comment:
The code:
<?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="ring"
android:useLevel="false">
<solid android:color="#android:color/white" />
<size
android:width="150dp"
android:height="150dp" />
</shape>
</item>
<item
android:bottom="50dp"
android:left="50dp"
android:right="50dp"
android:top="50dp">
<shape
android:shape="oval"
android:useLevel="false">
<solid android:color="#android:color/white" />
</shape>
</item>
</layer-list>
Note: The only changes made was in the sizes to accomodate your imageview of 150dp X 150dp. When using it for your radio button I highly reccomend using the 10x10dp sizes

Drawable xml with horizontal line and circle in middle

I want to create a drawable xml file for the shape below. It will be like a horizontal line should fill the width of the layout and a circle in the middle.
Can anyone help me on this? Thanks in advance.

Keep it simple
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:height="1dp"
android:gravity="center">
<shape android:shape="rectangle">
<solid android:color="#ff0000" />

</item>
<item
android:width="56dp"
android:height="56dp"
android:gravity="center">
<shape android:shape="oval">
<solid android:color="#ff0000" />
</shape>
</item>
</layer-list>
output

hope this helps

Create your drawable file and put below code.
And change your color code red.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#color/colorAccent" />
<size
android:width="10dp"
android:height="10dp" />
</shape>
</item>
<item>
<rotate
android:fromDegrees="180"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="90">
<shape
android:shape="line"
android:top="1dp">
<stroke
android:width="0.5dp"
android:color="#color/colorAccent" />
</shape>
</rotate>
</item>

Use below drawable XML into your views background :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:width="100dp"
android:height="100dp"
android:gravity="center">
<shape android:shape="oval">
<solid android:color="#android:color/holo_red_dark" />
<!--background color of box-->
</shape>
</item>
<item
android:height="10dp"
android:gravity="center">
<shape android:shape="rectangle">
<solid android:color="#android:color/holo_red_dark" />
<!--background color of box-->
</shape>
</item>
</layer-list>

Attributes height and width in <item/> are supported since 23 api.
For earlier versions you can use following code:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:gravity="center">
<shape android:shape="rectangle">
<size android:height="1dp" />
<solid android:color="#ff0000" />
</shape>
</item>
<item android:gravity="center">
<shape android:shape="oval">
<size
android:width="30dp"
android:height="30dp" />
<solid android:color="#ff0000" />
</shape>
</item>

Drawing a rectangle inside an oval doesn't give the desired result

I tried to make a button wherein a square shape should be inside a circle shape. It works well on a square with a circle but not with the other way around and I wonder why. Here's my xml code so far for this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="#dimen/tab_space" android:right="#dimen/tab_space">
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<size android:width="80dp" android:height="80dp" />
<gradient android:angle="-90" android:startColor="#990000" android:endColor="#550000" />
<stroke android:width="1dp" android:color="#110000" />
</shape>
</item>
<item android:left="#dimen/tab_space" android:right="#dimen/tab_space">
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<size android:width="50dp" android:height="50dp" />
<gradient android:angle="-90" android:startColor="#ff0000" android:endColor="#990000" />
<stroke android:width="1dp" android:color="#440000" />
</shape>
</item>
</layer-list>
Any solution for this?

You can try this. It worked for me.
chat_icon.xml:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<padding android:left="7pt" android:top="8pt" android:right="7pt" android:bottom="8pt"/>
<solid android:color="#android:color/white" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<stroke android:color="#color/jade" android:width="2dip"/>
<solid android:color="#color/white" />
</shape>
</item>
Then, to use it in your layout, declare it as follows:
<ImageView
android:id="#+id/chat_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/chat_icon"
