From java code

Or if you prefer, assign the values using java methods.

mDrawView.setDrawColor(newPaint.getColor())
         .setPaintStyle(newPaint.getStyle())
         .setDither(newPaint.isDither())
         .setDrawWidth((int) newPaint.getStrokeWidth())
         .setDrawAlpha(newPaint.getAlpha())
         .setAntiAlias(newPaint.isAntiAlias())
         .setLineCap(newPaint.getStrokeCap())
         .setFontFamily(newPaint.getTypeface())
         .setFontSize(newPaint.getTextSize())
         .setZoomEnabled(true)
         .setMaxZoomFactor(15)
         .setZoomRegionScale(4)
         .setZoomRegionScaleMin(2)
         .setZoomRegionScaleMax(5);

I use a new Paint instance and read all the attributes from that, but you can assign it directly.
