Android how to measure time (few days) in app -


Sorry, if the title is confusing, then I will explain: I am creating an app that registers the user's action , Writes it as a string in the form of a database (eg, 17 July 2014 17:45), and then, when the first entry is made, then I have to measure 3 days, so when it lasts 3 days , Then I will ask the user to do something. How can I do this?

You should use Unix and make it long .

Long time = System TimeTimilis (); 3 day difference: 
  Boolean ish daydaily (long time saved time) {if (SystemCurrenttime milliseconds) - saved time> 1000 * 3600 * 24 * 3) back true; return false; }

edit value corrected

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
