How to give Round corners and blurred background to a linear layout?

I am trying to add a linear layout with rounded corners and blurred background in my app. So far ive managed to give the layout rounded corners but i cant figure out how to give it a blurred background.Ive tried setting an alpha attribute in the xml file but it dosent work.
Heres what i want to achieve:
The Drawable resource file:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#fff"/>
<stroke android:width="0.5dp" android:color="#B1BCBE" />
<corners android:radius="160dp"/>
<padding android:left="0dp" android:top="0dp" android:right="0dp" android:bottom="0dp" />
</shape>
The Xml code of the layout:
<LinearLayout
android:id="#+id/team_lay"
android:layout_width="match_parent"
android:layout_height="95dp"
android:layout_marginTop="40dp"
android:background="#drawable/layout_bg"
android:orientation="horizontal">
</LinearLayout>
What i have achieved so far:
How can i achieve the desired results?
TIA..!!!

You can achieve it by create a blur background as a xml file and then set background of your container view to it.
Try my example:
blur_background.xml
<?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="#4CAF50" />
</shape>
</item>
<item>
<shape
android:shape="rectangle">
<solid android:color="#AA000000" />
</shape>
</item>
</layer-list>
And your container layout:
<LinearLayout
android:id="#+id/team_lay"
android:layout_width="match_parent"
android:layout_height="95dp"
android:layout_marginTop="40dp"
android:background="#drawable/blur_background"
android:orientation="horizontal">
</LinearLayout>
Hope it help. ^^

So i fount the solution myself. I changed the transparency of the solid color in the drawable resouce file(as mentioned here https://stackoverflow.com/a/41865518/8175719 ) and it worked.

I want to add strokes to a view

I'm trying to add strokes to a view using drawable.
But I want add it only in side parts(left and right), not in whole parts.
Is there any good way to add stroke in side parts?
Below is my drawable xml code. (leanear_border_gray.xml)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="2dp"
android:color="#778899"/>
</shape>
and below is my target view xml code.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/linear_border_gray"
android:layout_weight="1">
....
</LinearLayout>

You need to wrap your shape into layer-list drawable with rectangular shape, add stroke and using top and bottom margins with negative values "hide" top and bottom lines, like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-4dp" android:bottom="-4dp">
<shape android:shape="rectangle">
<stroke android:width="2dp" android:color="#778899"/>
</shape>
</item>
</layer-list>

You can do it by using layer-list drawable suggested by #iDemigod
Your Layout should be like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="vertical"
android:layout_marginTop="20dp"
android:background="#drawable/border_left_right"
android:layout_gravity="center"
android:layout_weight="1">
</LinearLayout>
Note: If you are giving android:layout_height="match_parent" and android:layout_weight="1" then you must have to set android:layout_width="0dp" and vice versa for android:layout_width="match_parent".
File: border_left_right.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-4dp" android:bottom="-4dp">
<shape android:shape="rectangle">
<stroke android:width="2dp" android:color="#07060b"/>
</shape>
</item>

Edittext as spinner

I have a editext which I would like to show as drop down. SO for that I have background.xml file:
<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
<shape>
<solid android:color="#ffffff" />
<stroke android:width="1dp" android:color="#000000" />
<padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
</shape>
</item>
<item>
<bitmap android:gravity="right" android:src="#drawable/ic_arrow_drop_down" />
</item>
</layer-list>
</item>
</selector>
And added that as background for my edittext. This is what I get:
As you can see there is slight gap between the image and editext border. I would like to make my edittext like this:
How can I achieve this?

Try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/bg"
android:orientation="horizontal">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#android:color/transparent" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerInParent="true"
android:background="#drawable/bgnew"
android:src="#drawable/ic_android_black_24dp" />
</LinearLayout>
</LinearLayout>
Create bg.xml like this
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Background Color -->
<solid android:color="#ffffff" />
<!-- Border Color -->
<stroke android:width="1dp" android:color="#ff9900" />
</shape>
create a bgnew.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Background Color -->
<solid android:color="#ffffff" />
<!-- Border Color -->
<stroke android:width="1dp" android:color="#color/colorAccent" />
</shape>
Output

Create a RelativeLayout with EditText and ImageView UI Components :).
Don't complicate yourself.

Just try Linear layout with layout orientation horizontal of EditText and ImageView. It is simple.

Shadow Layout with 9-patch and background color transparent?

I would like to add a custom layout an edge with shadow, exactly one like this:
http://inloop.github.io/shadow4android/
The problem is that I use this to add a semi / transparent background color: (corners_main_layout.xml)
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="6dp" />
<solid android:color="#color/bright_foreground_disabled_material_dark" />
</shape>
So I can not use for background 9-patch.
Is there any way to 9-patch with shadows and transparent background color?
If not .... How could make the effect?
PS: I have seen many custom XML to add shadows, but all are very poor.
Here example:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_recover_pass"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="...RecoverPassActivity"
android:background="#mipmap/fondo_01"
android:orientation="vertical">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/corners_main_layout">
</LinearLayout>
I Need shadow border rectangle White (it is transparent) similar to example 9-patch
------------EDIT---------------
I modified mi corners_main_layout.xml:
<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="6dp" />
<solid android:color="#color/bright_foreground_disabled_material_dark" />
</shape>
</item>
<item android:drawable="#drawable/shadow_custom" />
and result :-( :

yeah! i have solution!
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="6dp" />
<solid android:color="#color/bright_foreground_disabled_material_dark" />
</shape>
</item>
<item android:drawable="#drawable/shadow_custom_9patch"/>
</layer-list>
thanks for help!
