如何在recyclerView 的图片上添加onClickListener？

Question

我正在尝试使用 Glide 框架在这段代码中的图像上附加 onclick 侦听器，但我找不到解决方案。有人可以帮忙吗？

图像已经显示在模拟器中。

import android.content.Context
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ImageView
import android.widget.Toast

import com.bumptech.glide.Glide

import kotlinx.android.synthetic.main.item_custom_row.view.*

class ItemAdapter(private val context: Context, private val urls: ArrayList<String>) :
    RecyclerView.Adapter<ItemAdapter.ViewHolder>() {


    /**
     * Inflates the custom view which is designed in xml layout file
     */
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        return ViewHolder(
            LayoutInflater.from(context).inflate(
                R.layout.item_custom_row,
                parent,
                false
            )
        )
    }


    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        // Array with urls
        val url = urls[position]

        Glide.with(context)
            .load(url)
            .diskCacheStrategy(DiskCacheStrategy.ALL)
            .placeholder(R.drawable.placeholder)
            .into(holder.imageView)
    }

    // Gets the number of items in the list
    override fun getItemCount(): Int {
        return urls.size
    }
     // A ViewHolder describes an item view and metadata about its place within the RecyclerView.

    class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {

        val imageView: ImageView = view.iv_image
     }
}

我是 Java 开发人员，所以我无法使用 Kotlin 进行编码，但我将向您展示如何在 imageView 上设置 OnClickListener。在 imageView 上使用 OnclickListener 不需要 Glide 库。只需在您的 onBindViewHolder

中添加以下几行

holder.imageView.setOnClickListener(view -> {
            Toast.makeText(context, "this is number: "+position+" Image Selected", Toast.LENGTH_SHORT).show();
            // or your code for imageView
        });

您的新代码如下所示：-

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        // Array with urls
        val url = urls[position]

//code for onClick on image
holder.imageView.setOnClickListener(view -> {
            Toast.makeText(context, "this is number: "+position+" Image Selected", Toast.LENGTH_SHORT).show();
            // or your code for imageView
        });


        Glide.with(context)
            .load(url)
            .diskCacheStrategy(DiskCacheStrategy.ALL)
            .placeholder(R.drawable.placeholder)
            .into(holder.imageView)
    }

确保将我的代码中的 JAVA 更改为 Kotlin。如果您有任何问题，请告诉我
