android - 将 onClickListener 设置为 onBindViewHolder 中的整个项目

Question

我有一个 RecyclerView 适配器，我想将 onClick 设置为整个项目，但是这个代码以及当我也尝试使用 myViewHolder.view 时。 setOnClickListener(..) 两者仍然只监听复选框的点击。

如何将 onClickListener 设置为整个 item ？

public class DeliveryPointSelectionAdapter extends RecyclerView.Adapter<DeliveryPointSelectionAdapter.MyViewHolder> {
    private static final String TAG = MyViewHolder.class.getSimpleName();
    private List<DeliveryPoint> deliveryPointList;

    interface OnItemCheckListener {
        void onItemCheck(DeliveryPoint deliveryPoint);
        void onItemUncheck(DeliveryPoint deliveryPoint);
    }

    @NonNull
    private OnItemCheckListener onItemCheckListener;

    public DeliveryPointSelectionAdapter(List<DeliveryPoint> deliveryPointList, @NonNull OnItemCheckListener onItemCheckListener) {
        this.deliveryPointList = deliveryPointList;
        this.onItemCheckListener = onItemCheckListener;
    }

    @NonNull
    @Override
    public DeliveryPointSelectionAdapter.MyViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int viewType) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.dialog_select_deliverypoints_to_change_item, viewGroup, false);
        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, int i) {
        DeliveryPoint deliveryPoint = deliveryPointList.get(i);
        myViewHolder.tvFormattedString.setText(deliveryPoint.domesticAddress.formattedString);
        myViewHolder.checkBox.setChecked(deliveryPoint.isCheckedForLocationUpdate);

        myViewHolder.linearLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DeliveryPoint deliveryPoint1 = deliveryPointList.get(myViewHolder.getAdapterPosition());
                if (myViewHolder.checkBox.isChecked()) {
                    deliveryPoint1.setCheckedForLocationUpdate(true);
                    onItemCheckListener.onItemCheck(deliveryPoint1);
                } else {
                    deliveryPoint1.setCheckedForLocationUpdate(false);
                    onItemCheckListener.onItemUncheck(deliveryPoint1);
                }
            }
        });

//        myViewHolder.checkBox.setOnCheckedChangeListener((buttonView, isChecked) -> {
//            DeliveryPoint deliveryPoint1 = deliveryPointList.get(myViewHolder.getAdapterPosition());
//            if (myViewHolder.checkBox.isChecked()) {
//                deliveryPoint1.setCheckedForLocationUpdate(true);
//                onItemCheckListener.onItemCheck(deliveryPoint1);
//            } else {
//                deliveryPoint1.setCheckedForLocationUpdate(false);
//                onItemCheckListener.onItemUncheck(deliveryPoint1);
//            }
//        });
    }

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

    @Override
    public int getItemViewType(int position){
        return position;
    }

    public static class MyViewHolder extends RecyclerView.ViewHolder {
        TextView tvFormattedString;
        CheckBox checkBox;
        LinearLayout linearLayout;
        View view;

        MyViewHolder(View view) {
            super(view);
            tvFormattedString = (TextView) view.findViewById(R.id.tv_formatted_string);
            checkBox = view.findViewById(R.id.cb_deliverypoint_checked);
            linearLayout = view.findViewById(R.id.ll_delivery_points_layout);
            this.view = view;
        }
    }
}

项目 View 布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/ll_delivery_points_layout"

    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

        <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:id="@+id/cb_deliverypoint_checked"/>

        <TextView
            android:id="@+id/tv_formatted_string"
            android:layout_width="match_parent"

            android:gravity="center_vertical"
            android:paddingStart="25dp"
            android:paddingTop="15dp"
            android:paddingEnd="25dp"
            android:textColor="@color/gray_text_light"
            android:textSize="18sp"

            tools:ignore="RtlSymmetry" />
    </LinearLayout>
</LinearLayout>

像其他用户已经提到的 myViewHolder.itemView.setOnClickListener 在 recyclerView 持有者上设置 onClick。 但是，如果我错了，请纠正我，您似乎希望您的复选框仅通过持有者单击来选中/取消选中。在这种情况下，您需要通过在布局 xml 中添加以下代码来禁用它

               android:clickable="false"
               android:focusable="false"
               android:focusableInTouchMode="false"

否则点击复选框将被点击而不执行你为itemview点击编写的代码。

由于您根据 deliveryPoint.isCheckedForLocationUpdate 将其设置为选中，因此您可以 notifyItemChanged(position) 在单击后更新持有人复选框。

看看这是否有帮助。

编辑: 根据评论，如果您实际上是在尝试切换 View 中的复选框，则应使用以下内容:同样，如果您创建一个新对象 deliveryPoint1 ，则不会对您在查看

myViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (myViewHolder.checkBox.isChecked()) {
                    deliveryPoint.setCheckedForLocationUpdate(false);
                    onItemCheckListener.onItemUncheck(deliveryPoint);
                } else {
                    deliveryPoint.setCheckedForLocationUpdate(true);
                    onItemCheckListener.onItemCheck(deliveryPoint);
                }
            }
        });
