我的应用程序需要以编程方式创建一个小的进度。 进度条没有方法来设置样式（我想一个小 进度条）。构造可以采取的AttributeSet，但它是一个 接口和要求我实现了一组功能。有没有一种方法 设置进度条的小风格？ （我不能使用XML创建 进度条）

My application need to create a small progressBar programmatically. ProgressBar doesn't have method to set the style (I want a small progressBar). The constructor can take a AttributeSet, however it is a interface and require me implements a set of functions. Is there a way to set the progressBar small style? ( I can't use xml to create progressBar)

推荐答案

在大多数情况下，如果你提供了一个的AttributeSet 手动你必须使用Android的之一。幸运的是，他们已经暴露，描述了一个小的进度条的属性集。使用此code：

Most of the time if you provide an AttributeSet manually you have to use one of Android's. Luckily, they've exposed the attribute set that describes a small progress bar. Use this code:

progressBar = new ProgressBar(activity, null, android.R.attr.progressBarStyleSmall);
