how to create android linearlayout cornar crap color?

I am new android devloper..
I want to do android linearlayout cornar crap color. I tried. I did not get the corner grab I saw. Below is my silk to give my linearlayout.
LinearLayout
<LinearLayout
android:orientation="horizontal"
android:background="#color/gnt_ad_green"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="4.0">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1.0"
android:text="Intergiration"
android:drawableLeft="#drawable/ic_filter"
android:drawablePadding="10.0dip"
android:gravity="center|left"
android:padding="15.0dip"
android:textColor="#color/colorWhite"
android:textSize="16.0sp" />
<LinearLayout
android:background="#color/colorBackgroundLight"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="3.0">
<TextView android:textSize="12.0sp"
android:textColor="#color/colorPrimary"
android:gravity="center"
android:text="sdfsdf gd"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</LinearLayout>
I want a design like this
simple image

You can try this
rect_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="#F00" />
</shape>
</item>
<item>
<rotate
android:fromDegrees="110"
android:pivotX="90%"
android:pivotY="90%"
>
<shape android:shape="rectangle" >
<solid android:color="#FFF" />
</shape>
</rotate>
</item>
</layer-list>
layout.xml
<?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" >
<View
android:layout_width="200dp"
android:layout_height="50dp"
android:background="#drawable/rect_background"/>
</LinearLayout>

maybe you have to use the image for this (add an image which contains a shape like this) and set this image as a background of your linear layout.

What's wrong with this layout that's causing the elevation shadow not to appear?

I'm trying to use Android Elevation to achieve the 'shadow' look for a view. The following is the layout xml:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.sample.app.Main2Activity">
<LinearLayout
android:layout_width="395dp"
android:layout_height="match_parent"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:orientation="vertical"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:clipChildren="false">
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="165dp"
android:background="#FFFFFF"
android:padding="30dp"
android:layout_margin="30dp"
android:elevation="10dp"
android:text="TextView" />
</LinearLayout>
</android.support.constraint.ConstraintLayout>
This is how the layout looks:
Look ma, no shadows!
Any suggestions to fix this?

Here you go.... maybe you need someone to do it for you then....
I used a card view instead...
xml layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:id="#+id/card_view"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:layout_gravity="center"
android:layout_margin="5dp"
card_view:cardCornerRadius="5dp"
card_view:contentPadding="10dp">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/textView"
android:text="hello"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:textStyle="bold"/>
<TextView
android:id="#+id/textView2"
android:text="world"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/textView"
android:layout_marginTop="10dp"/>
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
Add these to your app gradle file
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:cardview-v7:25.1.0'
result:
and if you dont want to use a card view.....
xml -> layout

<shape android:shape="rectangle">
<solid android:color="#fff"/>
<padding android:bottom="10dp" android:top="10dp"/>
</shape>
</item>
</layer-list>
result:
happy coding....

I'll get to the answer, but some background first. I was trying to achieve the look with a custom view that used a ConstraintLayout. This view would be used in another layout. I was when I tried using a simple TextView that I realised that the shadows weren't being rendered because, thus destroying my assumption that it was something ConstraintLayout related.
What worked?
I know, from the documentations, that shadows and rendered using a View's background. This, I have, and indeed, it was a solid color with no alpha value (as others on SO have mentioned).
Much like so:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>
It was after I added android:radius to this, and then the shadows were rendered.
<?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="1dp" />
</shape>
And if you were wondering, why not set it to 0dp? Well, the shadows disappear again when the radius values were set to 0dp.

How to add colored border on cardview?

I am new to Android and this is my first question here.
I am trying to add a colored vertical border at the beginning of the cardview. How can I achieve it on xml ? I tried adding it with empty textview but it is messing up the whole cardview itself. Please check the picture link posted below for example.
activity_main.xml
<android.support.v7.widget.CardView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
card_view:contentPadding="16dp"
card_view:cardElevation="2dp"
card_view:cardCornerRadius="5dp">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
style="#style/Base.TextAppearance.AppCompat.Headline"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Title" />
<TextView
style="#style/Base.TextAppearance.AppCompat.Body1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Content here" />
</LinearLayout>
</android.support.v7.widget.CardView>
Many thanks

Start From the material design update, it support app:strokeColor and also app:strokeWidth. see more
to use material design update. add following code to build.gradle(:app)
dependencies {
// ...
implementation 'com.google.android.material:material:1.0.0'
// ...
}
and Change CardView to MaterialCardView

try doing:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
card_view:cardElevation="2dp"
card_view:cardCornerRadius="5dp">
<FrameLayout
android:background="#FF0000"
android:layout_width="4dp"
android:layout_height="match_parent"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:orientation="vertical">
<TextView
style="#style/Base.TextAppearance.AppCompat.Headline"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Title" />
<TextView
style="#style/Base.TextAppearance.AppCompat.Body1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Content here" />
</LinearLayout>
</android.support.v7.widget.CardView>
this removes the padding from the cardview and adds a FrameLayout with a color. You then need to fix the padding in the LinearLayout then for the other fields
Update
If you want to preserve the card corner radius create card_edge.xml in drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#F00" />
<size android:width="10dp"/>
<padding android:bottom="0dp" android:left="0dp" android:right="0dp" android:top="0dp"/>
<corners android:topLeftRadius="5dp" android:bottomLeftRadius="5dp"
android:topRightRadius="0.1dp" android:bottomRightRadius="0.1dp"/>
</shape>
and in the frame layout use android:background="#drawable/card_edge"

As the accepted answer requires you to add a Frame Layout, here how you can do it with material design.
Add this if you haven't already
implementation 'com.google.android.material:material:1.0.0'
Now change to Cardview to MaterialCardView
<com.google.android.material.card.MaterialCardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
app:cardCornerRadius="8dp"
app:cardElevation="2dp"
app:strokeWidth="1dp"
app:strokeColor="#color/black">
Now you need to change the activity theme to Theme.Material. If you are using Theme.Appcompact I will suggest you to move to Theme.Material for future projects for having better material design in you app.
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">

I think this solution may not be efficient but it serves the purpose and adds flexibility with the border width.
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="40dp"
android:layout_gravity="center"
card_view:cardBackgroundColor="#color/some_color"
card_view:cardCornerRadius="20dp"
card_view:contentPadding="5dp"> <!-- Change it to customize the border width -->
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
card_view:cardCornerRadius="20dp"
card_view:contentPadding="5dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Add your UI elements -->
</RelativeLayout>
</android.support.v7.widget.CardView>
</android.support.v7.widget.CardView>

CardView extends FrameLayout, so it support foreground attribute. Using foreground attribute can also add border easily.
layout as follows:
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/link_card"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:foreground="#drawable/bg_roundrect_ripple_light_border"
app:cardCornerRadius="23dp"
app:cardElevation="0dp">
</androidx.cardview.widget.CardView>
bg_roundrect_ripple_light_border.xml
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/ripple_color_light">
<item>
<shape android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="#DDDDDD" />
<corners android:radius="23dp" />
</shape>
</item>
<item android:id="#android:id/mask">
<shape android:shape="rectangle">
<corners android:radius="23dp" />
<solid android:color="#color/background" />
</shape>
</item>
</ripple>

my solution:
create a file card_view_border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/white_background"/>
<stroke android:width="2dp"
android:color="#color/red" />
<corners android:radius="20dip"/>
</shape>
and set programmatically
cardView.setBackgroundResource(R.drawable.card_view_border);

I would like to improve the solution proposed by Amit. I'm utilizing the given resources without adding additional shapes or Views. I'm giving CardView a background color and then nested layout, white color to overprint yet with some leftMargin...
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
card_view:cardElevation="2dp"
card_view:cardBackgroundColor="#color/some_color"
card_view:cardCornerRadius="5dp">
<!-- The left margin decides the width of the border -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:layout_marginLeft="5dp"
android:background="#fff"
android:orientation="vertical">
<TextView
style="#style/Base.TextAppearance.AppCompat.Headline"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Title" />
<TextView
style="#style/Base.TextAppearance.AppCompat.Body1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Content here" />
</LinearLayout>
</android.support.v7.widget.CardView>

I solved this by putting two CardViews in a RelativeLayout. One with background of the border color and the other one with the image. (or whatever you wish to use)
Note the margin added to top and start for the second CardView. In my case I decided to use a 2dp thick border.
<android.support.v7.widget.CardView
android:id="#+id/user_thumb_rounded_background"
android:layout_width="36dp"
android:layout_height="36dp"
app:cardCornerRadius="18dp"
android:layout_marginEnd="6dp">
<ImageView
android:id="#+id/user_thumb_background"
android:background="#color/colorPrimaryDark"
android:layout_width="36dp"
android:layout_height="36dp" />
</android.support.v7.widget.CardView>
<android.support.v7.widget.CardView
android:id="#+id/user_thumb_rounded"
android:layout_width="32dp"
android:layout_height="32dp"
app:cardCornerRadius="16dp"
android:layout_marginTop="2dp"
android:layout_marginStart="2dp"
android:layout_marginEnd="6dp">
<ImageView
android:id="#+id/user_thumb"
android:src="#drawable/default_profile"
android:layout_width="32dp"
android:layout_height="32dp" />
</android.support.v7.widget.CardView>

You can keep <androidx.cardview.widget.CardView
with android:foreground="#drawable/black_border"
black_border :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/white" />
<stroke
android:width="1dp"
android:color="#android:color/black" />
</shape>

Top border on a LinearLayout with transparent background

I am trying to add a top border to a LinearLayout with a transparent background.
The result should be like the following image, where the border is the top border of the "Jp Project" LinearLayout. The background color comes from a FrameLayout who is used as container.
This is the linear layout XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/menuItem"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/icon"
android:layout_width="45dp"
android:layout_height="45dp"
android:src="#drawable/notification_action"
android:padding="10dp"/>
<TextView
android:id="#+id/menuItemName"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:textSize="19sp"
android:textColor="#color/white"/>
<TextView android:id="#+id/counter"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_vertical"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#color/counter_text_color"
android:background="#drawable/counter_bg"/>
</LinearLayout>
This is the style code I am using at the moment:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:width="2dp"
android:color="#color/base_app_color" />
<solid android:color="#android:color/transparent"/>
</shape>
Which draws:
Have you got any way to fix it just using styles?

Set as your LinearLayout background the drawable with this code:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="-2dp" android:bottom="-2dp" android:right="-2dp">
<shape android:shape="rectangle">
<stroke android:width="2dp" android:color="#color/borderColor" />
<solid android:color="#color/backgroundColor" />
</shape>
</item>
</layer-list>

As the line should be middle aligned vertically between the Workplaces and Project menu items. I am identifying the Project item as an especial menu item and applying a different layout.
The layout code is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal"
android:background="#drawable/project_top_line">
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/icon"
android:layout_width="45dp"
android:layout_height="45dp"
android:src="#drawable/notification_action"
android:padding="10dp"/>
<TextView
android:id="#+id/menuItemName"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:textSize="19sp"
android:textColor="#color/white"/>
<TextView android:id="#+id/counter"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_vertical"
android:textAppearance="#android:style/TextAppearance.Medium"
android:textColor="#color/counter_text_color"
android:background="#drawable/counter_bg"/>
</LinearLayout>
</LinearLayout>
The style code is:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:width="2dp"
android:color="#color/base_app_color" />
<solid android:color="#android:color/transparent"/>
</shape>
which draws a line in the middle of the first linear layout.

I think you only need a blue line so you can do something like this:
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#android:color/holo_blue_dark" />

Make a file called border.xml and add this to your layout for making only top border.
<item
android:left="-1dp"
android:right="-1dp"
android:bottom="-1dp"
android:top="1dp">
<shape
android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="#color/black" />
<solid android:color="#android:color/transparent" />
</shape>
</item>
like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/kellton_logo"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:background="#drawable/border"

implementation 'com.makeramen:roundedimageview:2.3.0'
on your xml file
<com.makeramen.roundedimageview.RoundedImageView
android:id="#+id/img_home_assistance"
android:layout_width="match_parent"
android:layout_height="123dp"
app:riv_corner_radius="#dimen/padding_margin_15"
android:layout_marginTop="6.8dp"
android:layout_marginLeft="7.3dp"
android:layout_marginRight="7.5dp"
android:src="#drawable/migrate"
android:scaleType="centerCrop"/>
