The onCreate() method is invoked when the activity is started. The first thing you should do is chain upward to the superclass, so the stock Android activity initialization can be done. In our implementation, we then create the button instance (new Button(this)), tell it to send all button clicks to the activity instance itself (via setOnClickListener()), call a private updateTime() method (shown shortly), and then set the activity s content view to be the button itself (via setContentView()). NOTE: All widgets extend the View base class. You usually build the user interface out of a hierarchy of views, but in this example, we are using a single view. We will discuss that magical Bundle icicle in 16. For the moment, consider it an opaque handle that all activities receive upon creation.

The ContactInformation class will be similar to the previous Address class in that it will contain only contact information for an individual, company, or user. Figure 7-14 shows the ContactInformation class diagram.

There are five additional properties that can control one widget s alignment relative to another: android:layout_alignTop indicates that the widget s top should be aligned with the top of the widget referenced in the property. android:layout_alignBottom indicates that the widget s bottom should be aligned with the bottom of the widget referenced in the property. android:layout_alignLeft indicates that the widget s left side should be aligned with the left side of the widget referenced in the property. android:layout_alignRight indicates that the widget s right side should be aligned with the right side of the widget referenced in the property. android:layout_alignBaseline indicates that the baselines of the two widgets should be aligned. The last property in the list is useful for aligning labels and fields so that the text appears natural. Since fields have a box around them and labels do not, android:layout_alignTop will align the top of the field s box with the top of the label, which will cause the text of the label to be higher on-screen than the text entered into the field. So, if we want Widget B to be positioned to the right of Widget A, in the XML element for Widget B we need to include android:layout_toRight = "@id/widget_a" (assuming @id/widget_a is the identity of Widget A).

The ShoppingCart class will be for the shopping cart within the application. This class will outline the items that are added to the shopping cart while customers are shopping at the vineyard s online store. Figure 7-15 shows the ShoppingCart class diagram.

public void onClick(View view) { updateTime(); }

When processing a payment for merchandise, the customer will submit their credit card for payment. As you can see in the class diagram shown in Figure 7-16, the individual information of the specific credit card will be contained within the CreditCard class. You will not be storing any credit card information on the server or database, but the class will be used to pass the information along within the application.

In Swing, a JButton click raises an ActionEvent, which is passed to the ActionListener configured for the button. In Android, a button click causes onClick() to be invoked in the OnClickListener instance configured for the button. The listener is provided to the view that triggered the click (in this case, the button). All we do here is call that private updateTime() method:

What makes this even more complicated is the order of evaluation. Android makes a single pass through your XML layout and computes the size and position of each widget in sequence. This has a couple of ramifications: You cannot reference a widget that has not yet been defined in the file. You must be careful that any uses of fill_parent in android:layout_width or android: layout_height do not eat up all the space before subsequent widgets have been defined.

Summary

To examine how to use some of the techniques discussed so far, let s look at the ScreenSizes/EU4You sample application. This application has one activity (EU4You) that contains a ListView with the roster of European Union (EU) members and their respective flags (http://www.wpclipart.com/flags/Countries/index.html). Clicking one of the countries brings up the mobile Wikipedia page for that country. In the source code to this book, you will find four versions of this application. We start with an application that is ignorant of screen size and slowly add in more screenrelated features.
