Android button.setBackground

I want to set background for the button. With Android 4.1.2 everything works fine, but if launch with Android 4.0 I've got an error 

java.lang.NoSuchMethodError: android.widget.Button.setBackground

with code 

LayerDrawable composite = new LayerDrawable(layers);
button.setBackground(composite);

So how can I set LayerDrawable background but with Android 4.0 or earlier?

Solution

  • While Both of the above answers are close you should really use 

    Build.VERSION.SDK_INT

    as Build.VERSION.SDK returns a string, and has been deprecated since API 4

    if(Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN){
         LayerDrawable composite = new LayerDrawable(layers);
         button.setBackgroundDrawable(composite);
}else{
         LayerDrawable composite = new LayerDrawable(layers);
         button.setBackground(composite);
}
