Shape not getting applied to Button Selector in Android

Shape Radius defined in xml is not getting applied to Button Focus & Pressed state.
I have
instagram_button_style.xml as below:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/instagram_button_shape" android:state_focused="true" android:textColor="#color/colorAccent" />
<item android:drawable="#drawable/instagram_button_shape" android:state_pressed="true" android:textColor="#color/colorAccent" />
<item android:drawable="#color/colorButton" />
</selector>
and My instagram_button_shape.xml as:
<?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">
<corners android:radius="30dp" />
<solid android:color="#color/colorButton" />
</shape>
</item>
<item android:drawable="#drawable/instagram_gradient" >
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="30dp" />
</shape>
</item>
</layer-list>
Where
instagram_gradient is a jpg image
Using it in button like :
android:background="#drawable/instagram_button_style"
My Initial Button State:
My Pressed Button State
Expectation: I was expecting pressed state to have oval button, but Radius is not getting applied.
FINAL Update:
At last, after numerous research I ended up changing my .JPG gradient file to android_gradient shape file.

You need to set android:radius="30dp" in your #drawable/instagram_gradient
Try this way
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<Button
android:id="#+id/tvKioskMode"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:background="#drawable/instagram_button_style"
android:padding="10dp"
android:text="OPEN IN"

try this to change instagram_button_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">

</shape>
</item>
<item

android:drawable="#drawable/instagram_gradient"
android:left="30dp"
android:right="30dp"
android:top="30dp">
<shape android:shape="rectangle">
<solid android:color="#color/colorButton" />
<corners android:radius="30dp" />
</shape>
</item>
</layer-list>

The <layer-list> has items, and you define this item incorrectly:
<item android:drawable="#drawable/instagram_gradient">
<shape android:shape="rectangle">
<corners android:radius="30dp" />
</shape>
</item>
Indeed, android:drawable defines the Drawable used to render the layer. The nested shape is just ignored.
You have three options to reach your goal:
use a shape with a gradient, and remove the android:drawable="#drawable/instagram_gradient"
use a PNG with transparency and rounded corners for the the #drawable/instagram_gradient
and of course implement a custom Drawable

The simplest way is wrap your button with CardView. It has property called CornerRadius. That way you can round your button into custom corner shape.

Try this Updated,
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/instagram_button_shape"
android:state_selected="true" />
<item android:drawable="#drawable/instagram_button_shape" />
<item android:drawable="#color/colorButton" />
</selector>
now, when you click this botton set
buttonId.setSelected(true);

Android: selectableItemBackground not working on button with xml drawable

I made a rounded button with xml drawable and applied android:foreground="?attr/selectableItemBackground" in hope of getting a ripple effect. However, ripple effect does not work. Is there anyway to make the ripple effect work? As a workaround I wrapped the button with a FrameLayout and applied android:foreground="?attr/selectableItemBackground" to it, but in that case the ripple is rectangular and goes beyond button (as it is rounded).
xml:
<Button
android:id="#+id/reg_next"
android:layout_width="125dp"
android:layout_height="40dp"
android:text="#string/next"
android:layout_gravity="center"
android:textAllCaps="false"
android:textColor="#color/colorPrimary"
android:textSize="18sp"
android:background="#drawable/rounded_button_background"
android:foreground="?attr/selectableItemBackground"/>
rounded_button_background:
<?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="#ebeff1"/> <!-- this one is ths color of the Rounded Button -->
<stroke android:width="1px" android:color="#979797" />
<corners
android:radius="20dp"
android:bottomLeftRadius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp"/>
</shape>

You need to create ripple drawable and set it as button background (without foreground attribute):
rounded_button_background.xml
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#2793c9">
<item>
<shape
android:padding="10dp"
android:shape="rectangle">
<solid android:color="#ebeff1" /> <!-- this one is ths color of the Rounded Button -->
<stroke
android:width="1px"
android:color="#979797" />
<corners
android:bottomLeftRadius="20dp"
android:radius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>
</item>
</ripple>
If you want support api bellow 21 (without ripple effect), add this drawable to directory drawable-v21 and in directory drawable create these files:
rounded_btn_normal.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle">
<solid android:color="#ebeff1" /> <!-- this one is ths color of the Rounded Button -->
<stroke
android:width="1px"
android:color="#979797" />
<corners
android:bottomLeftRadius="20dp"
android:radius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>
rounded_btn_active.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle">
<solid android:color="#2793c9" /> <!-- this one is ths color of the Rounded Button -->
<stroke
android:width="1px"
android:color="#979797" />
<corners
android:bottomLeftRadius="20dp"
android:radius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>
rounded_button_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/rounded_btn_active" android:state_enabled="true" android:state_pressed="true" />
<item android:drawable="#drawable/rounded_btn_normal" android:state_enabled="true" />
</selector>

Android: Check box selector not working properly

I am developing an application in which i am using check box and applied selector on that. My code of check box is as follows :
<CheckBox
android:id="#+id/checkBox"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="0.5"
android:button="#drawable/custom_checkbox"
android:clickable="false"
android:focusable="false"
android:gravity="center" />
custom_checkbox.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/checkbox_checked" android:state_checked="true"/>
<item android:drawable="#drawable/checkbox_checked" android:state_pressed="true"/>
<item android:drawable="#drawable/checkbox_unchecked"/>
</selector>
checkbox_checked
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/green_tic"/>
<item>
<shape android:shape="rectangle" >
<corners android:radius="#dimen/corner_radius_for_ask_option"/>
<size
android:height="20dp"
android:width="20dp" />
</shape>
</item>
</layer-list>
checkbox_unchecked
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<stroke
android:width="2px"
android:color="#color/color_light_grey" />
<corners android:radius="#dimen/corner_radius_for_ask_option" />
<size
android:height="20dp"
android:width="20dp" />
</shape>
</item>
</layer-list>
The above code is working fine on Note 3 and same kind of phone. It looks like :
But on samsung s2 it looks like :

Try adding a transparent solid to your shapes:
<shape android:shape="rectangle" >
<corners android:radius="#dimen/corner_radius_for_ask_option"/>
<size
android:height="20dp"
android:width="20dp" />
<solid android:color="#android:color/transparent"/>
</shape>
Same for the other drawable XML.

How to customize button in android without using image

you can create like this below image by programmatically.

Border on the left side of the button only

Here is my button_style.xml which i am including with my button. However, I still can't seem to get the border on the left. Can anyone help me here please?
ps - My background should be transparent
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<layer-list>
<item android:left="2dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#999999"/>
</shape>
</item>
</layer-list>
</selector>

Try this
<?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="#android:color/transparent" />
</shape>
</item>
<item
android:bottom="-2dp"
android:right="-2dp"
android:top="-2dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="2dp"
android:color="#FFF" />
</shape>
</item>
</layer-list>

There is some inherit problem with the borders of the button. But I found the best way to do it. Let say if you want a border only on the left side of the button. In the MainActivity xml file where the button is placed do it like this -
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/newstyle"
android:orientation="vertical" >
<Button
android:id="#+id/button3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
android:gravity="center_vertical"
android:paddingLeft="10sp"
android:text="Button"
android:textAllCaps="false"
android:textColor="#939393"
android:textSize="20sp" />
</LinearLayout>
For the newstyle.xml file which will be located in the drawable use this code -
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:bottom="0sp"
android:left="-2sp"
android:right="-2sp"
android:top="-2sp">
<shape android:shape="rectangle" >
<solid android:color="#ffffff" />
<stroke
android:width="1sp"
android:color="#d6d6d6" />
</shape>
</item>
</layer-list>
So the whole idea is -
Keep the background of the button as #null and keep the button in the linera layout. Give the background to the liner layout and voila its done..:)..

Try this
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<padding android:left="1dp" />
<solid android:color="#999999" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#android:color/transparent" />
</shape>
</item>
</layer-list>

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<layer-list>
<item android:left="2dp"
android:right="0dp"
android:top="0dp"
android:bottom="0dp"
>
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#999999"/>
</shape>
</item>
</layer-list>
</selector>
try this it may work
