键入的文本不会显示在通知中

问题描述 投票：0回答：1

我创建了一个应用程序，允许您输入通知的内容并选择应显示通知的日期和时间。一切正常，除了用户在 EditText 中输入的文本不会出现在显示的通知中。怎么解决呢？预先感谢您！

  • 首先，您必须从用户输入通知文本的EditText 获取文本。假设您有一个带有 ID 提醒编辑文本的 EditText。你会得到这样的文字：
val editTextR = findByView<EditText>(R.id.reminderEditText) 
val userText = reminderEditText.text.toString()
  • 其次，将输入文本传递给Intent：
reminderIntent.putExtra("REMINDER_TEXT", userText)

方法设置提醒：

@RequiresApi(Build.VERSION_CODES.S)
private fun setReminder(year: Int, month: Int, day: Int, hourOfDay: Int, minute: Int) {
    val calendar = Calendar.getInstance()
    calendar.set(year, month, day, hourOfDay, minute)

    if (calendar.timeInMillis > System.currentTimeMillis()) {
        if (alarmManager.canScheduleExactAlarms()) {
            val reminderIntent = Intent(this, ReminderReceiver::class.java)
            val editTextReminder = findViewById<EditText>(R.id.reminderEditText)
            val userText = editTextReminder.text.toString()
            reminderIntent.putExtra("REMINDER_TEXT", userText)
            reminderIntent.putExtra("REMINDER_TIME", calendar.timeInMillis)
            val pendingIntent = PendingIntent.getBroadcast(
                this, 0, reminderIntent, PendingIntent.FLAG_IMMUTABLE
            )

            alarmManager.setExactAndAllowWhileIdle(
                AlarmManager.RTC_WAKEUP,
                calendar.timeInMillis,
                pendingIntent
            )

            Toast.makeText(
                this,
                "Notification set at: ${calendar.time}",
                Toast.LENGTH_SHORT
            ).show()
        } else {
            Toast.makeText(this, "Device doesn't support exact alarms", Toast.LENGTH_SHORT).show()
        }
    } else {
        Toast.makeText(this, "Enter date from the future", Toast.LENGTH_SHORT).show()
    }
}

请记住将 R.id.reminderEditText 替换为布局中 EditText 的实际 ID。
