    <p>I have a TimePicker which I'd like to use to determine a length of time a user can stay connected. Lets say the time now is 10:00 if the user selects 11:00 - I'd like the source code below to determine that there are 60 minutes between the current time - and the time selected and set that to a string/long (minutes) which I then have displayed as a textview. </p> <p>I've coded everything as I thought it should be - however the textview never seems to update with minutes value. Everytime I attempt to view the data - I get a value of 0 not matter what the timepicker is set to.</p> <p>Anyone have any suggestions? I'm stumped at the moment and I'm not sure what else to try. </p> <p>ADDEDITDEVICE.JAVA (where the timepicker and minutes determination takes place)</p> <pre><code>public class AddEditDevice extends Activity { private long rowID;

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).
