动态创建按钮并将其添加到 LinearLayout

fun but_gen (line:String, dec:String, contactframe:LinearLayout, tag:String) {
    val contacts = "Vasya|Fedya|Masha".split("|")
    for (contact in contacts) {
        val button = Button(this).apply {
            text = contact
        }
        contactframe.addView(button)
    }
}

如何为他们创建一个组监听器setOnClickListener并通过文本进行识别？如果它是在按钮之前创建的，它还能运行吗？

在布局上，我将 upline 块放在 parentline 的顶部，并通过 css 样式将其压到顶部。Bootstrap 4中是否有内置方法？我没有找到Murzilka。

.upline {
    z-index: 1100;
    position: absolute;
    background-color: green;
  width: 300px;
  height: 100px
}
.parentline {
    background-color: blue;
  width: 300px;
    height: 200px
}
