setBackground vs setBackgroundDrawable Android

Question

I want to set background drawable of a view  There are two methods for this  as far as I see   setBackground and setBackgroundDrawable    When I use setBackground  it says it has been added in API level 16 but my project s min SDK version is 7  I assume it s not going to work on anything below 16  am I right  But when I use setBackgroundDrawable  it says it s deprecated   What am I supposed to use

I also had this problem  but I made a workaround using a ImageView   Try using a RelativeLayout and add a ImageView inside it  width and height  fill parent  scaleType  center     Also make sure the imageview is the first element inside the RelativeLayout  so it will act as background

i know this is an old question but i have a similar situation  and my solution was  button setBackgroundResource  R drawable ic button    Drawable d   button getBackground      and then you can play with the  Drawable   applying color filters  etc

seems that currently there is no difference between the 2 functions  as shown on the source code  credit to this post     public void setBackground Drawable background          noinspection deprecation     setBackgroundDrawable background       Deprecated public void setBackgroundDrawable Drawable background            so it s just a naming decision  similar to the one with fill-parent vs match-parent

Now you can use either of those options  And it is going to work in any case   Your color can be a HEX code  like this   myView setBackgroundResource ContextCompat getColor context  Color parseColor   FFFFFF        A color resource  like this   myView setBackgroundResource ContextCompat getColor context R color blue background      Or a custom xml resource  like so   myView setBackgroundResource R drawable my custom background     Hope it helps

You can also do this   try        myView getClass   getMethod android os Build VERSION SDK INT  gt   16    setBackground     setBackgroundDrawable   Drawable class  invoke myView  myBackgroundDrawable     catch  Exception ex            do nothing     EDIT  Just as pointed out by  BlazejCzapp it is preferable to avoid using reflection if you can manage to solve the problem without it  I had a use case where I was unable to solve without reflection but that is not case above  For more information please take a look at http   docs oracle com javase tutorial reflect index html

It s deprecated but it still works so you could just use it  But if you want to be completly correct  just for the completeness of it    You d do something like following   int sdk   android os Build VERSION SDK INT  if sdk  lt  android os Build VERSION CODES JELLY BEAN        setBackgroundDrawable      else       setBackground        For this to work you need to set buildTarget api 16 and min build to 7 or something similar
