android - Call a method in MainActivity.java on event that happens in a library file -


itemprop = "text">

I included the library in my Android project In the mainActvitiy.java, the onCreate method contains something like this: 

  SimpleCardStackAdapter adapter = new simple cardstock adapter (this); // This library should also be done on an event in class: adapter.add (new cardmodel ("Heading 2", "Description 2 goes here", R.ZDraravable (Arrowable Picture 2));

Now, in CardContainer.java (which is related to the swipeable card library) is an event on which I have a new item adapter adapter.add (. ..) . The adapter was defined in mainactivity.java as you can see above. How can I get it?

I first thought about defining a new method in main activity and then calling it from its library category, like: 

  Public Zero Call Frame Library () {Adapter.add (...); }

However, the method and adapters need to define static, except that I do not know how to make this method of main activity available in CardContainer.java.

I believe that I need to create a kind of listener to check the menactivity that happens in CardContainer. I do not know how to do this.

Any help is appreciated!

card dialogue to communicate by main activity For, you can define an interface in cardcontainer and implement it in MainActivity . This event occurs in CardContainer , when it can call the interface method to add the adapter to cardmodel . 

  Public class card container extends ... {CardContainer Event Listener M-Mailback; // Define an Interface Public Interface CardContainerEventListener {Public Zero AddToAdapter (); } // Callback Request Register method to register callback {activity callback} {mCallback = (CardContainer Event Listener) Callback; } Some functions (nothing less) than {//}, callback method mCallback.addToAdapter (); }} The implementation of public class main activity activity cardcountainer is spread. Cardcontainer listener {// Make sure you register the main activity with CardContainer, // Card Container. Call the registrar callback (this), AdoAdapter () {adapter.add (...); }}

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. 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
