如何在Android上显示Yes/No对话框?

是的，我知道有AlertDialog。但我很惊讶地知道在Android中显示对话框有多么困难(好吧，至少不是程序员友好的)。

我曾经是一名。net开发人员，我想知道在android上是否有类似的功能?

if (MessageBox.Show("Sure?", "", MessageBoxButtons.YesNo) == DialogResult.Yes){
    // Do something...
}

你可以在Kotlin中轻松完成:

 alert("Testing alerts") {
    title = "Alert"
    yesButton { toast("Yess!!!") }
    noButton { }
}.show()

Kotlin在Android::

    override fun onBackPressed() {
        confirmToCancel()
    }

    private fun confirmToCancel() {
        AlertDialog.Builder(this)
            .setTitle("Title")
            .setMessage("Do you want to cancel?")
            .setCancelable(false)
            .setPositiveButton("Yes") {
                dialog: DialogInterface, _: Int ->
                dialog.dismiss()
                // for sending data to previous activity use
                // setResult(response code, data)
                finish()
