Remarks

Sets the right-hand compound drawable of the TextView to the specified icon and sets an error message that will be displayed in a popup when the TextView has focus. The icon and error message will be reset to null when any key events cause changes to the TextView's text. The drawable must already have had Drawable#setBounds set on it. If the error is null, the error message will be cleared (and you should provide a null icon as well).
