私はTimePickerを使用して、ユーザーが時間を選択できるようにしました。こことここも参照してください。しかし、ユーザーに2番目を選択させる方法も見つかりませんでした。これで、ユーザーは時と分を選択できますが、秒は選択できません。02:05:10の時間を設定したい場合は、どうすればよいですか？TimePickerを使用して秒を選択する方法は？

私はGitHubでオープンソースプロジェクトを公開しました。これには秒単位のTimePickerがあります。

迅速で汚い方法の1つは、2つのTimePickersを使用することです。1つは時間、分、もう1つは秒として使用します。最初の数分間で未使用の時間を非表示にします。これは24時間モードでのみ機能します。最初に秒単位のタイムピッカーを宣言する必要があるため、下に配置します。
<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>

最善の解決策は、Timeクラスと3つのNumberPickerを使用して、独自のTimePickerを作成することだと思います。

これを回避する最善の方法は、タイムピッカーの代わりに3つの別々の「ナンバーピッカー」を作成することです...私はそれらを線形レイアウト内に配置し、正常に機能しました。
次に、3つの別々の変数内に値を格納するだけです。int Hours、int Minutes、int Secondsを使用して、計算を行います。
これは、ウイルスを含む可能性のある外部ソースをダウンロードせずに回避する方法でした。

これを行うためにKotlin拡張関数を作成しました。それは厄介ですが、それは仕事を成し遂げます：
/**
* 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
}
res/values/ids.xmlプログラムで秒フィールドを参照できるように、このIDをに追加する必要もあります。R.id.second
<item name="second" type="id"/>
