1final Button view = (Button) findViewById(_list.get(i));
2 view.setOnClickListener(new View.OnClickListener()
3 {
4
5 @Override
6 public final void onClick(final View _v)
7 {
8 final TimePickerDialog.OnTimeSetListener listener = new TimePickerDialog.OnTimeSetListener()
9 {
10 public final void onTimeSet(final TimePicker _view, final int _hourOfDay, final int _minute)
11 {
12 final TextView timeView = (TextView) findViewById(_timeTextViews.get(index));
13 final StringBuilder builder = new StringBuilder().append(_hourOfDay).append(":");
14 builder.append(_minute < 10 ? "0" + _minute : _minute);
15 timeView.setText(builder);
16 }
17 };
18
19 final TimePickerDialog dialog = new TimePickerDialog(ScheduleActivity.this, listener, 12, 0, false);
20 dialog.show();
21 }
22 });
