推荐答案

延长搜索栏类并覆盖其的OnDraw（）方法。有，但是你想，你可以画拇指和进步的背景。

Extend the Seekbar class and override its onDraw() method. There you can draw the thumb and progress background however you want.

创建进度绘制静态背景（更容易比计划绘制），并加入到资源。您可以将此作为XML或自定义类的构造函数的进步绘制。

Create a drawable progress background statically (easier than drawing in program.) and add to resources. You can set this as progress drawable in xml or in your custom class constructor.

class MySeekbar extends Seekbar {

    // In Constructor load the thumb image into static members.

    // override onDraw draw the thumb.
    void onDraw(Canvas canvas) {
         canvas.save();
         canvas.drawBitmap(mThumb, left, top, right, bottom);
         canvas.restore();
    }
}
