推荐答案

您不能让搜索栏绘制其拇指比水平偏移任何其他方式。

You can't make SeekBar to draw its thumb any other way than offset horizontally.

在code，实际上吸引拇指在AbsSeekBar.onDraw，有它看到，它只是水平偏移。
然而，你可能让自己的小部件延长进度，这将得出所需的任何方式拇指（弧）。但你也需要做出响应触摸它，进度预计转换为线性范围。

The code that actually draws thumb is in AbsSeekBar.onDraw, and there it's seen it's just horizontal offset. You may however make your own widget extending ProgressBar, which would draw thumb whatever way is needed (in arc). But you'll also need to make response to touches to translate it to linear range that ProgressBar expects.
