我画了个画布的矩形, 我在想,有没有 任何财产或方式 给一个小影子。
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);
}
谢谢 谢谢
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);
所以根据你的需求量身定做,这样就能解决问题了。
在您的情况中, 请在您的代码中添加 pincel1. setShadowLayer( 1.0 0. 0f, 0.0f, 2.0f, 0xFF000000); 。
