How to programmatically set drawableRight on Android Edittext?

You can use the function below:

editText.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.drawableRight, 0);

or (if you want to pass the drawable itself instead of its ID)

editText.setCompoundDrawablesWithIntrinsicBounds(null, null, ContextCompat.getDrawable(context,R.drawable.drawableRight), null)

The order of params corresponding to the drawable location is: left, top, right, bottom
