Trying to set a background image of a relativelayout

I am trying to set a background drawable image to a relativelayout that i have. I am using setBackground and it asks for a drawable not an int. I can giving it a drawable and it stills gives me an error. Here a section of my code.

rl.setBackground(R.drawable.loginbackground3);

This is the error I'm getting.

setBackground (android.graphics.drawable.Drawable) in View cannot be applied to (int).

Very confused please help?

Because of inconsistency of library from android itself, First, you need to create method getDrawable :

private Drawable getDrawable(int id) {
  final int sdk = android.os.Build.VERSION.SDK_INT;
  if (sdk >= android.os.Build.VERSION_CODES.LOLLIPOP)  {
    return ContextCompat.getDrawable(getContext(), id);
  } else {
    return getContext().getResources().getDrawable(id);
  }
}

Then, create method setBackgroundView :

private void setBackgroundView(View v, int drawable_Rid) {
  Drawable background = getDrawable(drawable_Rid);
  final int sdk = android.os.Build.VERSION.SDK_INT;
  if (sdk >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
    v.setBackground(background);
  } else {
    v.setBackgroundDrawable(background);
  }
}

And finally call the setBackgroundView with drawable name like this :

setBackgroundView(rl, R.drawable.loginbackground3);

Try this: 

rl.setBackgroundResource(R.drawable.loginbackground3);

or if you want to do like yours in that case you need to check build version(if you are building for lower version's).

final int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    rl.setBackgroundDrawable( getResources().getDrawable(R.drawable.loginbackground3) );
} else {
    rl.setBackground( getResources().getDrawable(R.drawable.loginbackground3));
}

//assuming your Layout is named relativelayout1:

 RelativeLayout r1 = (RelativeLayout) findViewById(R.id.relativelayout1);
 r1.setBackgroundResource(R.drawable.sample);

You need to load the drawable using that drawable reference.

Drawable background = rl.getContext().getResources().getDrawable(R.drawable.loginbackground3);
rl.setBackground(background);

Note that if you're using the support libraries you can solve the deprecation of getDrawable like so:

Drawable background = ContextCompat.getDrawable(rl.getContext(), R.drawable.loginbackground3);
rl.setBackground(background);
