iSpectrum－用Java编写iPhone程序 2
iSpectrum－用Java编写iPhone程序 1
?? ?官方提供的demo截图
?? ?先分析一下iSpectrum官方demo的框架
1 Launcher是程序入口，类似于main.m，实际上代码解构也差不多
?
public void applicationDidFinishLaunching(UIApplication app){ UIWindow window = new UIWindow();window.initWithFrame(UIScreen.mainScreen().bounds());nav = new UINavigationController();UIViewController ctr = new UIViewController();ctr.init();ctr.setTitle("Action sheet");ctr.setView(new MainView(nav));nav.initWithRootViewController(ctr);window.addSubview(nav.view());window.makeKeyAndVisible();}?2 看看mainview，没有delloc确实很爽，不过由于没有nib，所以只能用initWithFrame很原始的添加组件了。
?
public class MainView extends UIView {/** * Fields */private UIActionSheet actionSheet;private UINavigationController nav;/** * * @param nUINavigationController containing this view. */public MainView(UINavigationController n){super();init();nav = n;/* * ActionSheet */actionSheet = new UIActionSheet();actionSheet.init();actionSheet.setActionSheetStyle(UIActionSheetStyle.UIActionSheetStyleBlackOpaque);actionSheet.setDelegate(new ActionSheetDelegate(this));actionSheet.setTitle("How many items do you want to display ?");actionSheet.addButtonWithTitle("Cancel");actionSheet.setCancelButtonIndex(0);actionSheet.dismissWithClickedButtonIndexAnimated(0, true);actionSheet.addButtonWithTitle("One item");actionSheet.addButtonWithTitle("Two items");actionSheet.addButtonWithTitle("Three items");actionSheet.addButtonWithTitle("Four items");/* * Button * Being used to open the UIActionSheet. */UIButton button = new UIButton(){//@Overridepublic void controlEvent() {// Display the UIActionSheetactionSheet.showInView(this.superview());}};button.initWithFrame(CGRect.CGRectMake(85, 30, 150, 31));button.setBackgroundImageForState(UIImage.imageNamed("buttonBackground.tiff"), 0);button.setTitleForState("Create view", 0);button.setTitleColorForState(UIColor.blackColor(), 0);button.addTargetActionForControlEvents(UIControlEvents.UIControlEventTouchUpInside);addSubview(button);}/** * * @returnnavCurrent UINavigationController. */public UINavigationController getNavigationController(){return nav;}}?3 同样也有delegation类
?
public class ActionSheetDelegate extends UIActionSheetDelegate {/** * Field */private MainView view;/** * * @param vMainView that create this object. */public ActionSheetDelegate(MainView v){super();init();view = v;}/** * Method called by system when user select a button on action sheet. * @param actionSheetActionSheet calling this method. * @param buttonIndexIndex of selected button. * *///@Overridepublic void actionSheetClickedButtonAtIndex(UIActionSheet actionSheet,int buttonIndex) {if(buttonIndex == 0){// Click on "cancel" buttonreturn;}else {UIView newView = new UIView().init();// Add to the new UIView as many subviews as user wants.for(int i=1; i<=buttonIndex; i++){UIImageView imageView = new UIImageView();imageView.initWithFrame(CGRect.CGRectMake(i*40, 100, 30, 30));imageView.setImage(UIImage.imageNamed("img"+i+".tiff"));newView.addSubview(imageView);}UIViewController viewController = new UIViewController().init();if(buttonIndex == 1)viewController.setTitle(buttonIndex + " added item");elseviewController.setTitle(buttonIndex + " added items");viewController.setView(newView);// Push this new view into UINavigationController stack.view.getNavigationController().pushViewControllerAnimated(viewController, false);}}}?? ? 从简单的demo中似乎看不到有用java的必要，因为完全无法用到java中很多功能和开源的代码，而且受到插件开发者的限制。
