RecyclerView ItemClickListener 在 OnBindViewHolder 中不起作用

Question

在 RecyclerView 中单击时如何获取特定文本视图的 getText(string)？ 我在 OnBindViewHolder 中尝试过 holder.itemview.setOnclickListener 但我在日志中没有看到任何内容。

我得到了解决方案，但它只适用于双击。 单击任何解决方案？？？

请检查下面我的适配器 class 代码

public class AddressAdapter extends FirestoreRecyclerAdapter<AddressModel, AddressAdapter.viewHolder> {
    

    public AddressAdapter(@NonNull FirestoreRecyclerOptions<AddressModel> options) {
        super(options);
    }


    @Override
    protected void onBindViewHolder(@NonNull viewHolder holder, final int position, @NonNull final AddressModel model) {
        holder.name.setText(model.getName());
        holder.locationID.setText(String.valueOf(holder.getAdapterPosition()+1) );
        holder.address.setText(model.getAddress());
        holder.address.setMovementMethod(new ScrollingMovementMethod());
        holder.name.setPaintFlags(holder.name.getPaintFlags() |  Paint.UNDERLINE_TEXT_FLAG);
   
         //Guys this is not works in single click only works in double click
        holder.imgDeleteLoc.setOnClickListener(v -> {
Toast.makeText(v.getContext(), "clicked", Toast.LENGTH_SHORT).show();
         
            Log.d("cl",holder.getText().toString());
        });
    }

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


    class viewHolder extends RecyclerView.ViewHolder {
         TextView locationID,name,address;
        ImageView imgDeleteLoc;

        public viewHolder(@NonNull View itemView) {
            super(itemView);
            locationID=itemView.findViewById(R.id.tvAddressIdCounter);
            name=itemView.findViewById(R.id.tvName);
            address=itemView.findViewById(R.id.tvAddress);
            imgDeleteLoc=itemView.findViewById(R.id.imgDeleteLoc);
           
        }
    }
}

请任何人在单击 recyclerview 时帮助获取特定的 textview 内容。

Answer 1

你只需要打电话

holder.imgDeleteLoc.setOnClickListener(v -> {
        Log.d("cl",holder.address.getText().toString());
    });

Answer 2

您不应该再次使用 findViewById ，您可以尝试通过以下任一方式获取文本：

• holder.address.getText()
• model.getAddress()

Answer 3

首先用我的代码在这里更新：

 class viewHolder extends RecyclerView.ViewHolder { TextView locationID,name,address; ImageView imgDeleteLoc; public viewHolder(@NonNull View itemView) { super(itemView); locationID=itemView.findViewById(R.id.tvAddressIdCounter); name=itemView.findViewById(R.id.tvName); address=itemView.findViewById(R.id.tvAddress); imgDeleteLoc=itemView.findViewById(R.id.imgDeleteLoc); } }

试试这个：

 String getAddress = holder.address.getText().toString();

Answer 4

如下更新ImageView或者您可以使用ImageButton

<ImageView
        android:id="@+id/imgDeleteLoc"
        android:clickable="true"
        android:layout_width="30dp"
        android:layout_height="40dp"
        android:clickable="true"
        android:focusable="true"
        android:src="@drawable/ic_baseline_delete_24"
        android:layout_gravity="end"
        android:layout_marginEnd="15dp"
        android:layout_marginTop="15dp"/>
