单击自定义通知操作按钮后显示对话框

如何解决单击自定义通知操作按钮后显示对话框

我使用了以下代码并且能够在 Android 应用中显示自定义通知。

MainActivity.kt

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // Create and register notification channel api 26+
        val channelId = "My_Channel_ID"
        val notificationId = 1

        createNotificationChannel(channelId)

        // Create an explicit intent for an activity in this app
        val intent = Intent(this,MainActivity::class.java)
        intent.apply {
            flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
        }
        val pendingIntent = PendingIntent.getActivity(this,intent,0)


        val deleteIntent = Intent(this,BharosaBroadcastReceiver::class.java)
        deleteIntent.apply {
            action = "Delete"
            putExtra("UserId","100")
            putExtra("notificationId",notificationId)
        }
        val deletePendingIntent = PendingIntent.getBroadcast(this,deleteIntent,0)

        var btn : Button = findViewById(R.id.btn)

        btn.setOnClickListener{
            val contentView = RemoteViews(packageName,R.layout.custom_push)
            contentView.setImageViewResource(R.id.image,R.mipmap.ic_launcher)
            contentView.setTextViewText(R.id.title,"Hello World")
            contentView.setTextViewText(R.id.text,"Please click the delete btton to delete")

            val notificationBuilder = NotificationCompat.Builder(this,channelId)
                    .setSmallIcon(R.drawable.ic_action_info)
                    .setColor(Color.GREEN)
                    .setCustomContentView(contentView)
                    .setStyle(NotificationCompat.DecoratedCustomViewStyle())
                    .setPriority(NotificationCompat.PRIORITY_DEFAULT)
                    .setContentIntent(pendingIntent)
                    contentView.setOnClickPendingIntent(R.id.delete,deletePendingIntent)
            with(NotificationManagerCompat.from(this)){
                notify(notificationId,notificationBuilder.build())
            }
        }
    }

    private fun createNotificationChannel(channelId:String) {
        // Create the NotificationChannel,but only on API 26+ (Android 8.0) because
        // the NotificationChannel class is new and not in the support library
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
            val name = "My Channel"
            val channelDescription = "Channel Description"
            val importance = NotificationManager.IMPORTANCE_DEFAULT

            val channel = NotificationChannel(channelId,name,importance)
            channel.apply {
                description = channelDescription
            }

            // Finally register the channel with system
            val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            notificationManager.createNotificationChannel(channel)
        }
    }
}

MyBroadcastReceiver.kt

class MyBroadcastReceiver: BroadcastReceiver(){
    override fun onReceive(context: Context?,intent: Intent?) {
        intent?.apply {
            val ussreId = getStringExtra("UserId")
            val notificationId = getIntExtra("notificationId",0)

            Toast.makeText(context,"Deleted ID: $ussreId",Toast.LENGTH_SHORT).show()

            context?.apply {
                // Remove the notification programmatically on button click
                NotificationManagerCompat.from(this).cancel(notificationId)
            }
        }
    }
}

我需要在以下通知中单击“删除”按钮时显示一个对话框：

对话框的代码如下：

var dialog = AlertDialog.Builder(requireContext())
dialog.setTitle("Delete?")
dialog.setMessage("Please confirm to delete it")
dialog.setPositiveButton("Delete",DialogInterface.OnClickListener { dialog,whichButton ->
        
    })

dialog.setNegativeButton("No",null)

var dialogUI = dialog.create();

dialogUI.setOnShowListener {

    val view = (it as AlertDialog).window
    view?.setBackgroundDrawableResource(R.drawable.alert_dialog_layout)

    // change positive button yes background
    val positiveButton: Button = (it as AlertDialog).getButton(DialogInterface.BUTTON_POSITIVE)
    positiveButton.background = resources.getDrawable(R.drawable.yes_alert_background)
    positiveButton.setTextColor(requireContext().resources.getColor(R.color.white))

    val negativeButton = it.getButton(DialogInterface.BUTTON_NEGATIVE)
    negativeButton.setTextColor(requireContext().resources.getColor(R.color.dialog_no_text))
}

dialogUI.show() 

请帮助我在单击自定义通知操作按钮后显示此对话框。
