android - Skew custom layout -

-

i've got custom layout , skew this: 

@override protected void ondraw(canvas canvas) {     canvas.skew(0f, 0.2f);     super.ondraw(canvas); }

and achieve enter image description here

although, want skew other side (i want right higher left) decided flip horizontally this

@override protected void ondraw(canvas canvas) {     canvas.scale(-1f, 1f, super.getwidth() * 0.5f, super.getheight() * 0.5f);     canvas.skew(0f, 0.2f);     super.ondraw(canvas); }

but button, can see below, flips too. can suggest me how flip layout not children inside?
