如何在Android中动态添加新的Android芯片? [英] How can I add the new android chips dynamically in Android?

问题描述

我有一个名为Question的类，其中包含标签的String数组.我正在尝试使用Kotlin在Recyclerview中显示每个问题，并在新芯片中显示每个标签.这些芯片将包含在ChipGroup中.

I have a class called Question which contains a String array of tags. I'm trying to show every question in a Recyclerview using Kotlin and every tag in a new chip. These chips will be included inside a ChipGroup.

我的问题是:

如何将阵列的每个标签元素添加到新芯片中? 我正在尝试执行此操作，但显然不起作用.

How can I add every tag element of the array into a new Chip? I'm trying to do this but It's obviously not working.

if (tags != null) {
    for (tag in tags) {
        val chip = Chip(itemView.context)
    }
}

谢谢大家！

推荐答案

您可以像添加其他任何ViewGroup一样添加Chip，如下所示:

You can add Chips the same way as any other ViewGroup like so:

for (index in tags.indices) {
  val chip = Chip(chipGroup.context)
  chip.text= "Item ${tags[index]}"

  // necessary to get single selection working
  chip.isClickable = true
  chip.isCheckable = true
  chipGroup.addView(chip)
}

对于singleSelection，请不要忘记添加到您的chipGroup中:

for singleSelection don't forget to add to your chipGroup:

chipGroup.isSingleSelection = true

或xml

app:singleSelection="true"

祝你好运，编码愉快！
