copied!<p>Have you tried following the <a href="http://developer.android.com/resources/tutorials/views/hello-timepicker.html" rel="nofollow">tutorial on the developers page</a> for the timepicker?</p> <p><strong>Edit:</strong></p> <p>Ok, so following the tutorial we have the update method for the textview that will show your time: </p> <pre><code>private void updateDisplay() { mTimeDisplay.setText( new StringBuilder() .append(pad(mHour)).append(":") .append(pad(mMinute))); } private static String pad(int c) { if (c >= 10) return String.valueOf(c); else return "0" + String.valueOf(c); } </code></pre> <p>The dialog that will be created for the user to pick the time:</p> <pre><code>@Override protected Dialog onCreateDialog(int id) { switch (id) { case TIME_DIALOG_ID: return new TimePickerDialog(this, mTimeSetListener, mHour, mMinute, false); } return null; } </code></pre> <p>And here is where I would add the restriction that you want, the callback method when the user sets the time. You need to get the current hour and minute, and if the user selects a past time, you do not display his changes and send him a Toast or something.</p> <p>Using the Calendar you can easily get it:</p> <pre><code>Calendar c = Calendar.getInstance(); // the callback received when the user "sets" the time in the dialog private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() { public void onTimeSet(TimePicker view, int hourOfDay, int minute) { if (mHour >= Integer.getInteger(c.get(Calendar.HOUR_OF_DAY)) && mMinute >= Integer.getInteger(c.get(Calendar.MINUTE))) { mHour = hourOfDay; mMinute = minute; updateDisplay(); } else //Display a toast or something to inform the user that he can't pick a past time. } </code></pre> <p>Now if you want the user to not be able to pick a previous time in the Dialog you created, you have to create your own hour picking screen, because the TimePickerDialog has no restrictions about what values you can pick. </p> <p>Hope it helps!</p>
