Как выбрать секунду с помощью TimePicker, Android

Я думаю, что лучшее решение — создать свой собственный TimePicker, используя класс Time и три NumberPicker.

Я опубликовал проект с открытым исходным кодом на GitHub, в котором есть TimePicker с секундами:

https://github.com/IvanKovac/TimePickerWithSeconds

Взглянуть.

Один быстрый и грязный способ - использовать два TimePickers, один для часов, минут и использовать минуты на другом как секунды. Скройте неиспользованные часы под первыми минутами. Это работает только в 24-часовом режиме. Сначала необходимо объявить таймер для секунд, поэтому он находится под.

<RelativeLayout
  <TimePicker
    android:id="@+id/timePicker_Sec"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="76dp" />
  <TimePicker
    android:id="@+id/timePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignTop="@+id/timePicker_Sec"   
    android:layout_marginLeft="0dp" />
</RelativeLayout>

Лучшим способом обойти это было бы создать три отдельных «выборщика чисел» вместо таймера... Я поместил их в линейный макет, и он отлично работает.

Затем все, что вам нужно сделать, это сохранить значения внутри трех отдельных переменных. int часы, int минуты, int секунды и сделайте свой расчет.

Это был мой способ обойти это без загрузки каких-либо внешних источников, которые могут содержать вирусы.

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center">

            <NumberPicker
                android:id="@+id/numpicker_hours"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content">

            </NumberPicker>

            <NumberPicker
                android:id="@+id/numpicker_minutes"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="8dp"
                android:layout_marginRight="8dp">

            </NumberPicker>

            <NumberPicker
                android:id="@+id/numpicker_seconds"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content">

            </NumberPicker>

        </LinearLayout>

Для этого я написал функцию расширения Kotlin. Это грязно, но он выполняет свою работу:

/**
 * Adds seconds number picker into the [TimePicker] format programmatically.
 * */
fun TimePicker.addSeconds() {
    val system = Resources.getSystem()
    val idHour = system.getIdentifier("hour", "id", "android")
    val idMinute = system.getIdentifier("minute", "id", "android")
    val idAmPm = system.getIdentifier("amPm", "id", "android")
    val idLayout = system.getIdentifier("timePickerLayout", "id", "android")
    val spinnerHour = findViewById<View>(idHour) as NumberPicker
    val spinnerMinute = findViewById<View>(idMinute) as NumberPicker
    val spinnerAmPm = findViewById<View>(idAmPm) as NumberPicker
    val outerLayout = findViewById<View>(idLayout) as LinearLayout
    val layout = outerLayout.getChildAt(0) as LinearLayout
    layout.removeAllViews()
    (spinnerAmPm.parent as ViewGroup).removeView(spinnerAmPm)

    layout.addView(spinnerHour)
    setImeOptions(spinnerHour, 0)
    layout.addView(spinnerMinute)
    setImeOptions(spinnerMinute, 1)

    val spinnerSecond = createSecondPicker(spinnerHour.context)
    layout.addView(spinnerSecond)
    setImeOptions(spinnerAmPm, 2)
    val params = spinnerHour.layoutParams
    spinnerSecond.layoutParams = params

    layout.addView(spinnerAmPm)
    setImeOptions(spinnerAmPm, 3)
}

private fun createSecondPicker(context: Context): NumberPicker {
    val spinnerSecond = NumberPicker(context)
    spinnerSecond.id = R.id.second
    spinnerSecond.setFormatter { i -> String.format("%02d", i) }
    spinnerSecond.minValue = 0
    spinnerSecond.maxValue = 59
    return spinnerSecond
}

Вам также нужно будет добавить этот идентификатор в res/values/ids.xml, чтобы вы могли программно ссылаться на поле секунд, используя R.id.second

<item name="second" type="id"/>

Привет этому сообщению за идею: https://stackoverflow.com/a/60601077/1709354

Я создал свой собственный выбор времени с секундами. Вы можете попробовать это здесь.

Я добавил некоторые другие функции.
