Given a closed Path object result is like this:

虽然这是我在寻找一些东西，与任何闭合路径工程的矩形。

Although that is a rectangle I'm looking for something which works with any closed Path.

推荐答案

虽然steelbytes的回答可能让您欣赏到渐变的各个部分更多的控制，你可以做到这一点不带路径：

While steelbytes' answer will probably give you more control over the individual sections of the gradient, you can do it without the path:

protected void onDraw(Canvas canvas)
{
    super.onDraw(canvas);
    Paint p = new Paint();
    // start at 0,0 and go to 0,max to use a vertical
    // gradient the full height of the screen.
    p.setShader(new LinearGradient(0, 0, 0, getHeight(), Color.BLACK, Color.WHITE, Shader.TileMode.MIRROR));
    canvas.drawPaint(p);
}
