我尝试使用recylerView创建一个不同公司的列表。所以发生了什么我显示底部工作表片段，其中我填充了不同公司名称的列表。我要求用户添加任何公司的不同名称，如果他们想要的。我从对话框中获得公司名称，并将该名称添加到recylerView列表。
但是当底部表单消失时，我丢失了用户添加的公司名称。我希望保留用户添加的公司名称。基本上，我希望创建一个列表视图，并希望使用对话框从用户那里获得列表视图项。
希望我能详细解释我的问题。下面是我的代码。

public class Item
  {
public String companyName;

public Item(String companyName) {
    this.companyName = companyName;
}

public String getCompanyName() {
    return companyName;
}

public void setCompanyName(String companyName) {
    this.companyName = companyName;}}`

在它下面我的适配器类

public class CustomAdapter_1 extends RecyclerView.Adapter<CustomAdapter_1.myViewHolder> {
List<Item> customAdapters;
Context context;

public CustomAdapter_1(Context context, List<Item> customAdapters) {
    this.customAdapters = customAdapters;
    this.context = context;

}

@NonNull
@Override
public myViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View v = LayoutInflater.from ( parent.getContext () ).inflate ( R.layout.custom_adapter_1, parent, false );
    myViewHolder myViewHolder = new myViewHolder ( v );
    return myViewHolder;
}

@Override
public void onBindViewHolder(@NonNull myViewHolder holder, int position) {
    holder.radioButton.setText ( customAdapters.get ( position ).getCompanyName () );

}

@Override
public int getItemCount() {
    return customAdapters.size ();
}

public class myViewHolder extends RecyclerView.ViewHolder {
    RadioButton radioButton;
    TextView textView;

    public myViewHolder(@NonNull View itemView) {
        super ( itemView );
        radioButton = (RadioButton) itemView.findViewById ( R.id.rdbtn1 );

    }
}

public void AddItem(Item item, int position) {
    customAdapters.add ( position, item );

}}

这是我的碎片

public class CustomFragment_1 extends BottomSheetDialogFragment {

private RecyclerView recyclerView;
private CustomAdapter_1 mAdapter;
ArrayList<Item> listOfItem = new ArrayList<> ();

String cName, listString;
StringBuffer sb = new StringBuffer ();
Button btn;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate ( R.layout.fragment_custom_1, container, false );

    recyclerView = (RecyclerView) view.findViewById ( R.id.customRV );
    btn = (Button) view.findViewById ( R.id.button1 );
    LinearLayoutManager linearLayoutManager = new LinearLayoutManager ( getContext () );
    recyclerView.setLayoutManager ( linearLayoutManager );

    mAdapter = new CustomAdapter_1 ( getContext (), listOfItem );
    recyclerView.setAdapter ( mAdapter );
    listOfItem.add ( new Item ( "Company 1" ) );
    listOfItem.add ( new Item ( "Company 2" ) );
    listOfItem.add ( new Item ( "Company 3" ) );

    btn.setOnClickListener ( new View.OnClickListener () {
        @Override
        public void onClick(View view) {

            final FlatDialog flatDialog = new FlatDialog ( getActivity () );
            flatDialog.setTitle ( "Company Name" )
                    .setSubtitle ( "Please add the name of the company" )
                    .setFirstTextFieldHint ( "Company Name" )
                    .setFirstButtonText ( "ADD" )
                    .setSecondButtonText ( "CANCEL" )
                    .withFirstButtonListner ( new View.OnClickListener () {
                        @Override
                        public void onClick(View view) {
                            cName = flatDialog.getFirstTextField ();
                            listOfItem.add ( new Item ( flatDialog.getFirstTextField () ) ) ;
                            flatDialog.dismiss ();

                        }
                    } )
                    .withSecondButtonListner ( new View.OnClickListener () {
                        @Override
                        public void onClick(View view) {
                            flatDialog.dismiss ();
                        }
                    } )
                    .show ();

        }
    } );

    return view;
}}

我真的很感谢你的时间，我感谢所有的时间。谢谢
