Android LinearLayout Add border with shadow around a LinearLayout

Question

I would like to create the same border of this LinearLayout as the example      In this example  we can see that the border is not the same all around the linearLayout  How can I create this using an XML drawable file   For now  I have only able to create a simple border all around the LinearLayout like this     lt  xml version  1 0  encoding  utf-8   gt   lt shape xmlns android  http   schemas android com apk res android  android shape  rectangle  gt     lt corners       android radius  1dp        android topRightRadius  0dp        android bottomRightRadius  0dp        android bottomLeftRadius  0dp    gt     lt stroke       android width  1dp        android color   E3E3E1    gt      lt solid android color   color blanc    gt    lt  shape gt

I found the best way to tackle this     You need to set a solid rectangle background on the layout  Use this code - ViewCompat setElevation view   value  On the parent layout set android clipToPadding  false

1 First create a xml file name  shadow xml in  drawable  folder and copy the below code into it     lt  xml version  1 0  encoding  utf-8   gt       lt layer-list xmlns android  http   schemas android com apk res android  gt           lt item gt               lt shape android shape  rectangle  gt                   lt solid android color   CABBBBBB    gt                   lt corners android radius  10dp    gt               lt  shape gt           lt  item gt            lt item             android bottom  6dp              android left  0dp              android right  6dp              android top  0dp  gt               lt shape android shape  rectangle  gt                   lt solid android color   android color white    gt                   lt corners android radius  4dp    gt               lt  shape gt           lt  item gt       lt  layer-list gt    Then add the the layer-list as background in your LinearLayout    lt LinearLayout         android id    id header bar          android layout width  match parent          android layout height  wrap content          android background   drawable shadow          android orientation  vertical  gt

As an alternative  you might use a 9 patch image as the background for your layout  allowing for more  natural  shadows     Result     Put the image in your  res drawable folder  Make sure the file extension is  9 png  not  png  By the way  this is a modified  reduced to the minimum square size  of an existing resource found in the API 19 sdk resources folder  I left the red markers  since they don t seem to be harmful  as shown in the draw9patch tool    EDIT   About 9 patches  in case you never had anything to do with them   Simply add it as the background of your View     The black-marked areas  left and top  will stretch  vertically  horizontally   The black-marked areas  right  bottom  define the  content area   where it s possible to add text or Views - you can call the unmarked regions  padding   if you like to    Tutorial  http   radleymarx com blog simple-guide-to-9-patch

I know this is late but it could help somebody   You can use a constraintLayout and add the following property in the xml           android elevation  4dp

This is so simple   Create a drawable file with a gradient like this   for shadow below a view below shadow xml   lt  xml version  1 0  encoding  utf-8   gt   lt shape xmlns android  http   schemas android com apk res android  gt      lt gradient     android startColor   20000000      android endColor   android color transparent      android angle  270   gt   lt  gradient gt   lt  shape gt    for shadow above a view above shadow xml   lt  xml version  1 0  encoding  utf-8   gt   lt shape xmlns android  http   schemas android com apk res android  gt      lt gradient     android startColor   20000000      android endColor   android color transparent      android angle  90   gt   lt  gradient gt   lt  shape gt    and so on for right and left shadow just change the angle of the gradient

Use this single line and hopefully you will achieve the best result   use   android elevation  3dp   Adjust the size as much as you need and this is the best and simplest way to achieve the shadow like buttons and other default android shadows  Let me know if it worked
