使用样式:填充绘制箭头的代码如下:

The code for drawing an arrow with Style: Fill is given below:

paint.setColor(Color.parseColor("#bdc0dc"));
paint.setStyle(Style.FILL);

paint.setColor(Color.BLACK);
paint.setStyle(Style.STROKE);
paint.setStrokeWidth(2);
canvas.drawPath(arrowPath, paint);

我得到的输出是这样的:

现在我想要做的是将样式设置为 Gradient(Style.gradient not present in android...) 以获得类似于下面给出的图像的箭头:

推荐答案

使用下面的代码..

paint.setShader(new LinearGradient(0, 0, 0, getHeight(), Color.BLACK, Color.WHITE, Shader.TileMode.MIRROR));
    canvas.drawPath(arrowPath, paint);
