Citation:
A LinearLayout which contains an ImageView and a TextView can be more efficiently handled as a compound drawable (a single TextView, using the drawableTop, drawableLeft, drawableRight and/or drawableBottom attributes to draw one or more images adjacent to the text). If the two widgets are offset from each other with margins, this can be replaced with a drawablePadding attribute.
Pour faire simple, tu dois pouvoir réduire certains linearlayout contenant 1 texte + 1 image à un simple textview.
