    <p>I have modified the code from first answer:</p> <ul> <li>it stores selected time in long form (milliseconds) which is easier to work with (using Calendar) then string</li> <li>it automatically shows selected time in summary field in user's format (12 or 24 hour)</li> </ul> <p>Updated code:</p> <pre><code>public class TimePreference extends DialogPreference { private Calendar calendar; private TimePicker picker = null; public TimePreference(Context ctxt) { this(ctxt, null); } public TimePreference(Context ctxt, AttributeSet attrs) { this(ctxt, attrs, android.R.attr.dialogPreferenceStyle); } public TimePreference(Context ctxt, AttributeSet attrs, int defStyle) { super(ctxt, attrs, defStyle); setPositiveButtonText(R.string.set); setNegativeButtonText(R.string.cancel); calendar = new GregorianCalendar(); } @Override protected View onCreateDialogView() { picker = new TimePicker(getContext()); return (picker); } @Override protected void onBindDialogView(View v) { super.onBindDialogView(v); picker.setCurrentHour(calendar.get(Calendar.HOUR_OF_DAY)); picker.setCurrentMinute(calendar.get(Calendar.MINUTE)); } @Override protected void onDialogClosed(boolean positiveResult) { super.onDialogClosed(positiveResult); if (positiveResult) { calendar.set(Calendar.HOUR_OF_DAY, picker.getCurrentHour()); calendar.set(Calendar.MINUTE, picker.getCurrentMinute()); setSummary(getSummary()); if (callChangeListener(calendar.getTimeInMillis())) { persistLong(calendar.getTimeInMillis()); notifyChanged(); } } } @Override protected Object onGetDefaultValue(TypedArray a, int index) { return (a.getString(index)); } @Override protected void onSetInitialValue(boolean restoreValue, Object defaultValue) { if (restoreValue) { if (defaultValue == null) { calendar.setTimeInMillis(getPersistedLong(System.currentTimeMillis())); } else { calendar.setTimeInMillis(Long.parseLong(getPersistedString((String) defaultValue))); } } else { if (defaultValue == null) { calendar.setTimeInMillis(System.currentTimeMillis()); } else { calendar.setTimeInMillis(Long.parseLong((String) defaultValue)); } } setSummary(getSummary()); } @Override public CharSequence getSummary() { if (calendar == null) { return null; } return DateFormat.getTimeFormat(getContext()).format(new Date(calendar.getTimeInMillis())); } } </code></pre>

    1. COGreat, but how do you supply a default value in a numeric format? When I use android:defaultValue="3600000" the defaultValue is a String, so it first needs to be parsed to Long.

    2. COYou are right I have added long parsing to the code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
