Question

[我试图制作AlertDialog，但是遇到了崩溃错误问题，我尝试了多种方法，但是仍然没有用，从通过添加ID将constrainlayout更改为LinearLayout，但此方法仍然有效

xml

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

            app:layout_constraintTop_toBottomOf="@+id/btnContonuewPayment" />

    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.cardview.widget.CardView>

我通过添加id并将其更改为Linearlayout尝试了此方法how to fix androidx.appcompat.widget.AppCompatButton cannot be cast to com.rey.material.widget.Button，但仍然崩溃

kotlin

private fun showDialog() {

    val dialogBuilder = AlertDialog.Builder(this)
    val viewDialogForget = layoutInflater.inflate(R.layout.dialog_payment,null)
    val continuew = viewDialogForget.findViewById<ImageView>(R.id.btnContonuewPayment)
    val cancel = viewDialogForget.findViewById<ImageView>(R.id.btnCancel)
    dialogBuilder.setView(viewDialogForget)
    dialogBuilder.setCancelable(false)
    val dialog = dialogBuilder.create()
    dialog.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))


    continuew.setOnClickListener {
        dialog.dismiss()
    }

    cancel.setOnClickListener {
        finish()
    }

    dialog.show()
}

无需在xml中为警报对话框创建其他按钮，可以通过编码顺利完成。这是一个例子。

private fun setupAlertDialogButton() {
    alertDialogButton.setOnClickListener {
        MaterialAlertDialogBuilder(this)
            .setTitle("Discard draft?")
            .setMessage("Your message.")
            .setPositiveButton("Discard") { dialog, which ->
                Toast.makeText(this, "Clicked discard", Toast.LENGTH_SHORT).show()
            }
            .setNegativeButton("Cancel") { dialog, which ->
                Toast.makeText(this, "Clicked cancel", Toast.LENGTH_SHORT).show()
            }
            .show()
    }
}

alertDialogBu​​tton应该是您的后退按钮ID
