But with code like this:
但是用这样的代码：
LinearLayout buttons = new LinearLayout(parentContext);
buttons.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout.LayoutParams buttonsParams =
new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
topLayout.addView(buttons, buttonsParams);
buttons.setLayoutParams(buttonsParams);
Button btnAdd = new Button(context);
btnAdd.setText("Add");
How can I set the style of the buttons (use a button bar) programmitically?

Well, Stylescan be applied to a Viewat initialization phase. For example:
好吧，样式可以应用于View初始化阶段。例如：
LinearLayout button = new LinearLayout(context, null, android.R.style.ButtonBar);

This worked for me:
这对我有用：
int buttonStyle = R.style.your_button_style;
Button button = new Button(new ContextThemeWrapper(context, buttonStyle), null, buttonStyle)

This is the only answer that actually delivered what I was looking for: http://belencruz.com/2013/04/set-styles-programmatically-in-android/
这是实际提供我正在寻找的唯一答案：http: //belencruz.com/2013/04/set-styles-programmatically-in-android/
Essentially, create a layout XML file that simply has a <Button/>element with the style you want. Then, inflate it programmatically and just customize the button text.
本质上，创建一个布局 XML 文件，该文件只包含<Button/>具有所需样式的元素。然后，以编程方式对其进行充气并自定义按钮文本。
Something along the lines of:
类似的东西：
<?xml version="1.0" encoding="utf-8"?>
<Button style="@style/your_custom_style_here"/>
In code:
在代码中：
Button button = (Button)getLayoutInflater().inflate(R.layout.your_custom_button_layout_file, null);
button.setText("Your Text");

LinearLayout button = new LinearLayout(context, null, android.R.style.ButtonBar);
(which is, judging by the comments, API dependable) I have also read ridoys answer from here [ Android Button Styling Programatically] which is
（也就是说，从评论来看，API 可靠）我还从这里阅读了ridoys 的答案 [ Android Button Styling Programatically]，它是
transferBtn.setBackgroundResource(R.layout.buttonstyle);
(exposing the above answers because one of these may also work for you, depending of API version you use),
（公开上述答案，因为其中一个也可能对您有用，具体取决于您使用的 API 版本），
But this is what worked for me(mind the change from "layout" to "drawable"):
但这对我有用（注意从“布局”到“可绘制”的变化）：
Button b = new Button(this);
b.setBackgroundResource(R.drawable.button_custom_green);

In my case style was not loaded at all when I pass them into Buttonconstructor.
It seems that was because I was using the material design view. Here what solved my case:
在我的情况下，当我将它们传递给Button构造函数时，根本没有加载样式。似乎是因为我使用的是材料设计视图。这里是什么解决了我的案子：
val themeWrapper = ContextThemeWrapper(
context,
R.style.AppTheme_ButtonPrimary // my button style
)
val button = MaterialButton(themeWrapper)
Please note that MaterialButtonwas created instead of Button.
请注意，MaterialButton是创建而不是Button.
