单击事件在自定义弹出窗口内不起作用

问题描述

我正在使用带有 2 个 TextViews 的自定义视图的 PopupWindow，我正在尝试响应单击事件，但单击事件未触发，以下是我正在使用的代码

    /* Get the binding object */
    val binding: XYZBinding = XYZBinding.inflate(
        LayoutInflater.from(applicationContext),null,false
    )
    binding.clickHandler = this
    
    /* Set the popup menu window */
    popupWindow = PopupWindow(binding.root)
    popupWindow.contentView = LayoutInflater.from(applicationContext)
        .inflate(R.layout.popup_menu_gang,false)

    popupWindow.isTouchable = true
    popupWindow.isFocusable = true
    popupWindow.isOutsidetouchable = true
    popupWindow.width = WindowManager.LayoutParams.WRAP_CONTENT
    popupWindow.height = WindowManager.LayoutParams.WRAP_CONTENT
    popupWindow.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))

    popupWindow.setondismissListener(PopupWindow.OndismissListener {
        window.attributes.alpha = alpha
        window.addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND)
        window.decorView.invalidate()
    })
    popupWindow.showAsDropDown(binding.layoutHeader.imageViewMenu)

我也尝试过直接使用 onClickListener 但效果不佳

    binding.textViewGangPopupRenameButtons.setonClickListener(View.OnClickListener {
        Toast.makeText(applicationContext,"working",Toast.LENGTH_SHORT).show()
    })

以下是我使用的xml

    <?xml version="1.0" encoding="utf-8"?>
    <layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto">

            </androidx.cardview.widget.CardView>

    </layout>

解决方法

使用 PopupView 设置文本视图的 ID .. 像这样

      ` val layoutInflater = activity!!
                .getSystemService(AppCompatActivity.LAYOUT_INFLATER_SERVICE) as 
           LayoutInflater
            val popupView: View = 
      layoutInflater.inflate(R.layout.custom_grid_bottomnav,null)
            val popupWindow = PopupWindow(
                popupView,ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT
            )

            // popupWindow.dismiss()
            val tx = popupView.findViewById<TextView>(R.id.text1) //change
            tx.setOnClickListener(object : View.OnClickListener {
                override fun onClick(v: View?) {
                   //Do what you want

} }`
