android - Kotlin-将项目添加到ExpandableListView

我正在尝试使用Kotlin在Android Studio内部动态填充可扩展列表 View 。但是到目前为止，我还无法找到任何最新的函数来执行此操作，我发现的所有函数似乎都已过时。这是我的基本代码:

private val shows = listOf("First", "Breaking Bad", "Game of Thrones", "Bob and Martin...")

    private val expandableListView: ExpandableListView by bind(R.id.theListView)

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        //Add items to expandable list view here
    }

提前致谢

最佳答案

对我来说，它工作正常。
在定义 list 数据的 Activity 中，执行以下操作:

private ArrayList<HeaderInfo> SectionList = new ArrayList<>();
...
//create the adapter by passing your ArrayList data
listAdapter = new ExpandableListAdapter(MyListActivity.this, SectionList);
//attach the adapter to the list
expandableListView.setAdapter(listAdapter);

这是我的可扩展列表适配器中的构造函数

public class ExpandableListAdapter extends BaseExpandableListAdapter {

private Context context;
private ArrayList<HeaderInfo> SectionList;

public ExpandableListAdapter(Context context, ArrayList<HeaderInfo>
SectionList) {
    this.context = context;
    this.SectionList = SectionList;
}
...
