本地通知（二）

以前写过一篇文章：本地通知，本文是基于此基础的一个简单的例子。

localnotificationAppDelegate.h

#import <UIKit/UIKit.h>

@class localnotificationViewController;

@interface localnotificationAppDelegate : NSObject <UIApplicationDelegate> {
	UIWindow *window;
	localnotificationViewController *viewController;
}

@property(nonatomic, retain) IBOutlet UIWindow *window;
@property(nonatomic, retain) IBOutlet localnotificationViewController *viewController;

@end

localnotificationAppDelegate.m

#import "localnotificationAppDelegate.h"
#import "localnotificationViewController.h"

@implementation localnotificationAppDelegate

@synthesize window;
@synthesize viewController;

#pragma mark -
#pragma mark Application lifecycle

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
	application.applicationIconBadgeNumber = 0;
	[self.window addSubview:viewController.view];
	[self.window makeKeyAndVisible];
	
	return YES;
}

#pragma mark -
#pragma mark Memory management

- (void)dealloc {
	[viewController release];
	[window release];
	[super dealloc];
}

@end

localnotificationViewController.h

#import <UIKit/UIKit.h>

@interface localnotificationViewController : UIViewController {
	IBOutlet UILabel *myLable1;
	IBOutlet UILabel *myLable2;
	IBOutlet UILabel *myLable3;
}

@property(nonatomic, retain) UILabel *myLable1;
@property(nonatomic, retain) UILabel *myLable2;
@property(nonatomic, retain) UILabel *myLable3;

- (IBAction)onChangeValue:(id)sender;

@end

localnotificationViewController.m

#import "localnotificationViewController.h"

@implementation localnotificationViewController

@synthesize myLable1, myLable2, myLable3;

- (void)viewDidLoad {
	[super viewDidLoad];
	[[UIApplication sharedApplication] cancelAllLocalNotifications];
}

- (void)viewDidUnload {
	self.myLable1 = nil;
	self.myLable2 = nil;
	self.myLable3 = nil;
}

- (void)dealloc {
	[myLable1 release], myLable1 = nil;
	[myLable2 release], myLable2 = nil;
	[myLable3 release], myLable3 = nil;
	[super dealloc];
}

#pragma mark -
#pragma mark onChageValue

- (IBAction)onChangeValue:(id)sender {
	UISwitch *switchBtn = (UISwitch *)sender;
	if (switchBtn.on) {
		UILocalNotification *notification = [[UILocalNotification alloc] init]; 
		NSDate *now = [NSDate date];  
		notification.timeZone = [NSTimeZone defaultTimeZone]; 
		notification.repeatInterval = NSDayCalendarUnit;
		notification.applicationIconBadgeNumber = 1;
		notification.alertAction = NSLocalizedString(@"显示", nil);
		switch (switchBtn.tag) {
			case 0:
			{
				notification.fireDate = [now dateByAddingTimeInterval:5];
				notification.alertBody = self.myLable1.text; 
			}
				break;
			case 1:
			{
				notification.fireDate = [now dateByAddingTimeInterval:10];
				notification.alertBody = self.myLable2.text; 
			}
				break;
			case 2:
			{
				notification.fireDate = [now dateByAddingTimeInterval:15];
				notification.alertBody = self.myLable3.text; 
			}
				break;
			default:
				break;
		}
		[notification setSoundName:UILocalNotificationDefaultSoundName];
		NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:
												 [NSString stringWithFormat:@"%d", switchBtn.tag], @"key", nil];
		[notification setUserInfo:dic];
		[[UIApplication sharedApplication] scheduleLocalNotification:notification];
	} else {
		NSArray *array = [[UIApplication sharedApplication] scheduledLocalNotifications];
		for (int i = 0; i < [array count]; i++) {
			UILocalNotification	*myUILocalNotification = [array objectAtIndex:i];
			if ([[[myUILocalNotification userInfo] objectForKey:@"key"] intValue] == switchBtn.tag) {
				[[UIApplication sharedApplication] cancelLocalNotification:myUILocalNotification];
			}
		}
	}
}

[2] 被TranslateAnimation弄晕了

来源: 互联网发布时间: 2014-02-18

被TranslateAnimation搞晕了。

bottomFrameAnimationOut = new TranslateAnimation(TranslateAnimation.RELATIVE_TO_SELF, 0f, TranslateAnimation.RELATIVE_TO_SELF, 0f, TranslateAnimation.ABSOLUTE, -205, TranslateAnimation.ABSOLUTE, 0);

原来这里的每一个参数都是相对于当前view的值。

如果你想点击一个按钮然后把一个view从一个地方移到另一个地方的话。

        mailboxHeaderBar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                final LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) mailboxHeaderBar.getLayoutParams();
                int bottomMargin = layoutParams.bottomMargin;
                if (bottomMargin < 0) {
                    mailboxHeaderBar.startAnimation(bottomFrameAnimationIn);
                    layoutParams.bottomMargin = 0;
                }else{
                    mailboxHeaderBar.startAnimation(bottomFrameAnimationOut);
                    layoutParams.bottomMargin = -205;
                }
                mailboxHeaderBar.setLayoutParams(layoutParams);
            }
        });

其实在你startAnimation的时候View的位置已经变了。 Animation里面的参数值是需要相对你移动view之后的值。有点晕 fuck

Dialog调用dismiss方法出现异常解决方法
本文原创，转载请保留原文地址： http://maosidiaoxian.iteye.com/blog/1547445

在使用Dialog时，调用dismiss方法，有时会出现异常：java.lang.IllegalArgumentException: View not attached to window manager

出现这个异常的原因可能是，在dismiss对话框的时候，它所在的activity因为一些原因已经先退出了，所以会出现这个异常。
目前我认为最好的解决方法是，使用Activity里面封装好的showDialog(int id)和dismissDialog(int id)方法。
使用示例代码如下（代码取自我的一个项目，去掉与本主题无关内容，如果有小的错误，请自行调试）：
