TimePickerDialogAndroidで選択可能な最大時間と最小時間を設定し、デフォルトの分間隔を1分から5分に変更する方法を探しています。
簡単だと思いましたが、道が見つかりません！

この回答は古くなっています
Android5以降では動作しません。
これはフィドラーの答えの拡張です。一部のAndroidバージョンでは、どういうわけかonTimeChangedListenerがTimePickerDialogによって設定されていません。
そのためのonTimeChangedメソッドは呼び出されません！現在、この問題の最善の解決策は、フィドルの最小/最大ロジックを使用してカスタムTimePickerDialogをコーディングすることです。
より醜い回避策はこれです。（リフレクションを使用してリスナーを追加する）また、現在選択されている時間を表示するようにタイトルを更新します。

ロリポップ以降のバージョンのAndroidの場合、この変更されたRangeTimePickerDialogクラスを使用できます
（lolipopから、Timepickerはデフォルトとしてクロックモード（マテリアルデザイン）を使用するため、古いカスタムクラスは機能しません。最新バージョンのスピナーにモードを変更して、クラスを再利用できます）

これを出発点として使用できます。
TimePickerDialogを拡張し、2つのメソッドsetMinとを追加しましsetMaxた。
このonTimeChanged方法では、新しい時間が最小/最大時間に対して有効であることを確認します。
それでもまだ磨きが必要です...
public class BoundTimePickerDialog extends TimePickerDialog {
private int minHour = -1, minMinute = -1, maxHour = 100, maxMinute = 100;
private int currentHour, currentMinute;
public BoundTimePickerDialog(Context context, OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView) {
super(context, callBack, hourOfDay, minute, is24HourView);
}
public void setMin(int hour, int minute) {
minHour = hour;
minMinute = minute;
}
public void setMax(int hour, int minute) {
maxHour = hour;
maxMinute = minute;
}
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
super.onTimeChanged(view, hourOfDay, minute);
boolean validTime;
if(hourOfDay < minHour) {
validTime = false;
}
else if(hourOfDay == minHour) {
validTime = minute >= minMinute;
}
else if(hourOfDay == maxHour) {
validTime = minute <= maxMinute;
}
else {
validTime = true;
}
if(validTime) {
currentHour = hourOfDay;
currentMinute = minute;
}
else {
updateTime(currentHour, currentMinute);
}

フィドラーのコードをリファクタリングした後：

// Somehow the onTimeChangedListener is not set by TimePickerDialog
// in some Android Versions, so, Adding the listener using
// reflections
try {
Class<?> superclass = getClass().getSuperclass();
Field mTimePickerField = superclass.getDeclaredField("mTimePicker");
mTimePickerField.setAccessible(true);
TimePicker mTimePicker = (TimePicker) mTimePickerField.get(this);
mTimePicker.setOnTimeChangedListener(this);
} catch (NoSuchFieldException e) {

最大/最小時間を設定するネイティブの方法はありませんが、延長するonTimeChangedかupdateTime、時間を範囲外の値に設定できないようにすると、おそらく機能します。

リフレクト付きのカスタムTimePickerを使用して、値を設定できます。
@Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
try {
Class<?> classForid = Class.forName("com.android.internal.R$id");
Field field = classForid.getField("minute");
NumberPicker mMinuteSpinner = (NumberPicker) findViewById(field.getInt(null));
mMinuteSpinner.setMinValue(5);
mMinuteSpinner.setMaxValue((60 / timeInterval) - 1);
List<String> displayedValues = new ArrayList<>();
for (int i = 0; i < 60; i += timeInterval)
displayedValues.add(String.format("%02d", i));
mMinuteSpinner.setDisplayedValues(displayedValues.toArray(new String[0]));
mMinuteSpinner.setWrapSelectorWheel(true);
} catch (Exception e) {
e.printStackTrace();
}
}
だからあなたはあなたが望む値を設定することができます

@Zarookaのソリューションを出発点として取り上げました。でもバグを見つけたと思います。すでに範囲外の開始時刻がある場合は、「onChanged」が拒否されていたため、それ以上移動できませんでした。そのため、最小値/最大値を設定するときに有効な範囲に移動するために、setMaxとsetMinを拡張しました。
