Question

I have a widget which is a TimePicker that retrieves the time saved in a field in a database.

Thing is that when the user changes the time value in the widget, this is not being saved in the database.

So I came across the setOnTimeChangedListener method that works like a charm, if you are only using the plus and minus signs in the widget. It does not capture the change if you are using the keyword.

Here is my code:

pickedTime.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {

        public void onTimeChanged(TimePicker arg0, int arg1, int arg2) {
            System.out.println("What time is it? "
                    + String.valueOf(arg0.getCurrentHour()) + ":"
                    + String.valueOf(arg0.getCurrentMinute()));
        }

    });

I’ve also tried unsuccessfully:

pickedTime.setOnFocusChangeListener and pickedTime.setOnKeyListener methods.

As mon3t found out, the option is to set android:AddStatesFromChildren=”true” in the XML file, as:

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:addStatesFromChildren="true" />
<TimePicker
    android:id="@+id/timePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:addStatesFromChildren="true" />

Or you can set that by code:

    datePicker.setAddStatesFromChildren(true);
    timePicker.setAddStatesFromChildren(true);

I really cannot understand what is the point of the default being the way it is.
