Effect shadow in rectangle canvas
提问by eric.itzhak
I have drawn a rectangle with canvas and I wonder if there is any property or way of giving a small shadow.
我用画布绘制了一个矩形，我想知道是否有任何属性或方法可以提供一个小阴影。
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint pincel1 = new Paint();
pincel1.setColor(Color.rgb(151, 217, 69));
RectF rectangle = new RectF(30, 20,200,100);
canvas.drawRoundRect (rectangle, 6, 6, pincel1);
}
Thanks
谢谢

Thisquestion contained the following code :
这个问题包含以下代码：
Paint mShadow = new Paint();
// radius=10, y-offset=2, color=black
mShadow.setShadowLayer(10.0f, 0.0f, 2.0f, 0xFF000000);
// in onDraw(Canvas)
canvas.drawBitmap(bitmap, 0.0f, 0.0f, mShadow);
So customize it a bit to your needs and that will do the trick.
因此，根据您的需要对其进行一些自定义，这样就可以解决问题。
In your case just add pincel1.setShadowLayer(10.0f, 0.0f, 2.0f, 0xFF000000);to your code.
在您的情况下，只需添加pincel1.setShadowLayer(10.0f, 0.0f, 2.0f, 0xFF000000);到您的代码中。
