    <p>To be able to delete some event you need its <strong>_id</strong> when fetching list of events. You can get it with adding <code>"_id"</code> to your selection array. Delete method could look like following </p> <pre><code>private void deleteEvent(int eventId) { Uri CALENDAR_URI = Uri.parse("content://com.android.calendar/events"); Uri uri = ContentUris.withAppendedId(CALENDAR_URI, eventId); getContentResolver().delete(uri, null, null); } </code></pre> <p><strong>Important:</strong> You should know that calling this does not really delete event database record, but only mark the record to delete with setting column deleted to 1. This is because of sync adapter to enable sync the deletion on server.</p> <p>With knowing that, you should edit your not deleted event query to not return deleted events. Example follows:</p> <pre><code>private List&lt;CalendarEntry&gt; readCalendar() { // Fetch a list of all calendars synced with the device, their title and _id // Notice that there is selection deleted = 0. Cursor cursor = getContentResolver().query(Uri.parse("content://com.android.calendar/events"), (new String[]{"_id", "title"}), "deleted = ?", new String[]{"0"}, null); List&lt;CalendarEntry&gt; calendarIds = new ArrayList&lt;CalendarEntry&gt;(); while (cursor.moveToNext()) { int _id = cursor.getInt(0); String title = cursor.getString(1); calendarIds.add(new CalendarEntry(_id, title)); } cursor.close(); return calendarIds; } </code></pre> <p>That you can just browse the list and select the event to delete.</p> <p>Here comes full working sample of list with deleting event on item click.</p> <pre><code>public class DeleteCalendarEventsActivity extends ListActivity { private TestAdapter mTestAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.list); mTestAdapter = new TestAdapter(this); setListAdapter(mTestAdapter); refreshList(); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { int eventId = mTestAdapter.getItem(position).mId; deleteEvent(eventId); refreshList(); } private void deleteEvent(int eventId) { Uri CALENDAR_URI = Uri.parse("content://com.android.calendar/events"); Uri uri = ContentUris.withAppendedId(CALENDAR_URI, eventId); getContentResolver().delete(uri, null, null); } private void refreshList() { mTestAdapter.clear(); for (CalendarEntry calendarEntry : readCalendar()) { mTestAdapter.add(calendarEntry); } } private List&lt;CalendarEntry&gt; readCalendar() { // Fetch a list of all calendars synced with the device, their title and _id Cursor cursor = getContentResolver().query(Uri.parse("content://com.android.calendar/events"), (new String[]{"_id", "title"}), "deleted = ?", new String[]{"0"}, null); List&lt;CalendarEntry&gt; calendarIds = new ArrayList&lt;CalendarEntry&gt;(); while (cursor.moveToNext()) { int _id = cursor.getInt(0); String title = cursor.getString(1); calendarIds.add(new CalendarEntry(_id, title)); } cursor.close(); return calendarIds; } static class TestAdapter extends ArrayAdapter&lt;CalendarEntry&gt; { TestAdapter(Context context) { super(context, 0); } @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = LayoutInflater.from(getContext()).inflate(android.R.layout.simple_list_item_1, null); } TextView textView = (TextView) convertView; textView.setText(getItem(position).mTitle); return convertView; } } static class CalendarEntry { private final int mId; private final String mTitle; CalendarEntry(int id, String title) { mId = id; mTitle = title; } } } </code></pre>

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.

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