Can I draw outside the bounds of an Android Canvas

try to set

android:clipChildren="false" 

to the parent view

The answer @numan gave is almost ok, the problem is memory allocation with that approach, so we should be doing this, instead:

// in constructor/elsewhere
Rect newRect = new Rect();

// in onDraw
canvas.getClipBounds(newRect);
newRect.inset(0, -20);  //make the rect larger
canvas.clipRect(newRect, Region.Op.REPLACE);

That solves the problem :-)

If you want to draw text out of bounds in TextView, you should be doing this instead:

<TextView
    ...
    android:shadowColor="#01000000"
    android:shadowDx="100" // out of right bound
    android:shadowDy="0"
    android:shadowRadius="1"
.../>

It's not working to use clipRect() like @numan's answer because TextView clip it's own rect in onDraw():

if (mShadowRadius != 0) {
    clipLeft += Math.min(0, mShadowDx - mShadowRadius);
    clipRight += Math.max(0, mShadowDx + mShadowRadius);

    clipTop += Math.min(0, mShadowDy - mShadowRadius);
    clipBottom += Math.max(0, mShadowDy + mShadowRadius);
}

canvas.clipRect(clipLeft, clipTop, clipRight, clipBottom);

Last but not least, Don't forget to set android:clipChildren="false" and android:clipToPadding="false" in your parent ViewGroup

If what you want is just draw outside the view bounds (programmatically), cut the long story short.

parentLayout.setClipChildren(false);

or via xml :

 android:clipChildren="false"
