java - Sharing a variable between many Activities in Android App -


I am giving my user login to Facebook, Twitter and G + on my app. After they log in, I want to know that they are logged in to every activity in my app. I want to find a way to find it on every activity. I know that you use activity in this way You can parse by: 

  intent = intent (new activity), main activity. Intent.putExtra ("Login Mode", "Facebook"); StartActivity;

But is there a problem with doing 10+ activities? Is there any easy way?

Which I want you to implement shared priorities ... are going on this By the way 

  shared preferences = priority manager .get defaults shared context (getApplicationContext ()); SharedPreferences.Editor Editor = preferences.edit (); Editor.putstring ("loginMethod", "Facebook"); Editor.commit;

And whenever you want to check the login mode, call the priority value ... 

  Shared Preferences = Preference Manager .get defaults shared context (getApplicationContext ()); String login mode = values ​​= preferences.getString ("loginMethod", "");

If you need more help then I would be happy to help you.

c# - Showing a SelectedItem's Property -

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...
