如何使用可自定义的拇指制作圆形 SeekBar? [英] How to make a Circular SeekBar with a customizable thumb?
问题描述
我正在使用 Android Studio，我需要一个这样的组件:
I'm using Android Studio and I need to have a component like this:
这些功能很重要:- 接受渐变颜色的progressDrawable；- 我可以作为组件获取的拇指，以便制作动画或在其上方放置文本(如图像中所示)；- 我可以自定义图像的拇指，而不仅仅是颜色；- ProgressBar/SeekBar 必须是圆形.- 我希望能够为动画目的以编程方式设置进度；
Those features are important: - progressDrawable that accepts gradient colors; - thumb that I can get as a component in order to animate or to put texts above it (like in the image); - thumb that I can customize with images, not just colors; - the ProgressBar/SeekBar must have a circular shape. - I want to be able to set the progress programmatically for animation purposes;
我对此进行了研究，只能接近我想要的结果，但这还不够.通过使用 Sliders，我可以根据需要自定义拇指，但我无法像在 ProgressBar 中那样控制背景来一点一点地设置它.通过使用 SeekBars 或 ProgressBars，我需要在自定义拇指或使组件循环之间进行选择.
I've made researches about it and I could only get close to the result that I wanted, but it's not enough. By using Sliders, I could customize the thumb as I wanted, but I don't have control over the background to set it bit by bit as in a ProgressBar. By using SeekBars or ProgressBars I need to choose between customize the thumb or making the component circular.
有什么办法吗?
或者至少，如果我可以使用常规的 Circular SeekBar，我会很满意，但可以访问拇指的位置，以便我可以用我选择的组件替换它.
Or at least, I would be satisfied if I could use a regular Circular SeekBar, but having access to the position of the thumb so I could replace it with a component of my choice.

有什么办法吗?
嗯，总有很多方法可以做到！
Well, There's always many ways to do it!
有很多库可以为你做这件事，所以没有必要重新发明轮子，但在你的情况下，我认为你可能必须发明你的自定义 轮子 因为您正在寻找的所有选项并不在一个库中，但是这些可能会让您感到高兴！: SeekArc , CircularSeekBar 和 CircularSeekBar.
There are lots of libraries that do it for you, so there is no need to re-invent the wheel, but in your case I think you probably must invent your custom wheel because all the options you're looking for is not in a library together, However these may make you happy! : SeekArc , CircularSeekBar and CircularSeekBar.
但是如果它们不能满足您的需求，您可以简单地分叉并将您的自定义选项添加到它们中.也许你应该看看 RoundedBitmapDrawable如果您想将圆形位图添加到 SeekBar 和 RadialGradient 如果你想使用渐变颜色.
But if they didn't satisfy your needs, you can simply fork and add your custom options to them. Maybe you should take a look at RoundedBitmapDrawable in case you want to add a circular bitmap to the SeekBar and RadialGradient if you want use gradient color for it.
