Android 如何将字符串数组从 RecyclerView 适配器传递到片段

Question

我正在从适配器中检索值并将值存储在 ArrayList<String> 中。我正在将 ArrayList 转换为字符串数组并将数组从 RecyclerView 适配器传递到其他片段，但我在其他 [=14] 中得到空值=].
这是将 ArrayList<String> 转换为字符串数组并发送到其他片段

的代码

String []tablesId=new String[tableId.size()];
           tablesId=tableId.toArray(tablesId);
        TableAssignConfirm confirm=new TableAssignConfirm();
           Bundle bundle=new Bundle();
               bundle.putStringArray("tablesIds",tablesId);
               confirm.setArguments(bundle);

这是从其他片段

中的 Bundle 检索值的代码

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View v=inflater.inflate(R.layout.table_assign_confirm, container, false);
       // Bundle bundle=getArguments().getStringArray("tableIds");
        String []getTables=getArguments().getStringArray("tableIds");
        Log.i("ids", Arrays.toString(getTables));
        return v;
    }

如何解决这个问题并获取值？

Answer 1

检查您的 getStringArray() 值。应该是getStringArray("tablesIds")。下次注意点))

Answer 2

Create an interface in your adapter

public interface OnItemClickListener {
  void onItemClicked(int position, ArrayList<DeliveryTimeSlot> list);
}

in your adapter call from fragment

Adapter adapter = new Adapter(context, list, new Adapter.OnItemClickListener() {
            @Override
            public void onItemClicked(int position, ArrayList<String> list) {
                  // Handle list and perform actions here
            }
        });

on your adapter

private OnItemClickListener onItemClickListener; // Global scope

in constructor call:

this.onItemClickListener = onItemClickListener;

on your item clicked event :

itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
      onItemClickListener.onItemClicked(position, _list);
    }
});

Answer 3

试试这个

Bundle bundle=getArguments();
if(bundle!=null){
    String []getTables=bundle.getStringArray("tableIds");
 }

在您的代码中

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View v=inflater.inflate(R.layout.table_assign_confirm, container, false);
       Bundle bundle=getArguments();
       if(bundle!=null){
          String []getTables=bundle.getStringArray("tableIds");
        }
        Log.i("ids", Arrays.toString(getTables));
        return v;
    }
