仿qq弹出列表的actionSheet用oc ,swift2和安卓的简单实现

本文主要是介绍仿qq弹出列表的actionSheet用oc ,swift2和安卓的简单实现，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在这公司上班也是醉了，一个产品公司不大利于程序员的发展，最主要的是公司不关心员工的成长，每天就知道在公司优化代码和换下公司的界面等一些繁琐的事情，完全是在浪费时间，倒不如学一些新的东西，今天学ios的时候发现了qq5.0版的那个退出程序时的上弹提示菜单栏，以前也就是用popwindow来实现的，今天看ios的代码实现起来确实是如此的简单，也就是已经封装好的一个控件UIActionSheet,想起安卓实现这功能是如此的操蛋，不得不觉得iphoe真的是有很大优势的，特别是去年6月出的swift语言，据说是比oc简单的多，学ios也是辛苦的，今天我也来实现一个安卓版的actionSheet。

先看下ios的实现这功能的截图和代码：

                                    

是不是很漂亮的界面，再看代码：

OC实现

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {self.window=[[UIWindow alloc]initWithFrame:[[UIScreen mainScreen] bounds]];
        self.window.backgroundColor=[UIColor whiteColor];
        [self.window makeKeyAndVisible];
        self.button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
        self.button.frame=CGRectMake(50, 250, 280, 50);
        [self.button setTitle:@"show actionSheet" forState:UIControlStateNormal];
        [self.button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        // self.button.font = [UIFont fontWithName:@"STHeiti-Medium.ttc" size:10];
        self.button.backgroundColor=[UIColor blueColor];
        [self.button addTarget:self action:@selector(click) forControlEvents:UIControlEventTouchUpInside];
        [self.window addSubview:self.button];
        return YES;
        }-(void)click{//底部弹出dialog
        UIActionSheet *sheet=[[UIActionSheet alloc]initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"发送给好友" otherButtonTitles:@"转载到空间相册",@"上传到群相册",@"保存到手机",@"收藏",@"查看聊天图片",nil];
        [sheet showInView:self.window];
        }

由于是初学者，所以用的是代码添加控件的方式

swift 2实现

 说实在的个人是喜欢使用

class ViewController: UIViewController {var actionSheetController : UIAlertController?var dataArray : Array<String> = ["取消","发送给好友","转载到空间相册","上传到群相册","保存到手机","收藏","查看聊天图片"]override func viewDidLoad() {super.viewDidLoad()}override func didReceiveMemoryWarning() {super.didReceiveMemoryWarning()}override func viewDidAppear(animated: Bool) {self.showActionSheet()}func showActionSheet(){self.actionSheetController = UIAlertController(title:nil, message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)self.actionSheetController?.addAction(UIAlertAction(title: self.dataArray[0], style: UIAlertActionStyle.Cancel, handler: { (action) -> Void in}))self.actionSheetController?.addAction(UIAlertAction(title: self.dataArray[1], style: UIAlertActionStyle.Default, handler: { (action) -> Void in}))self.actionSheetController?.addAction(UIAlertAction(title: self.dataArray[2], style: UIAlertActionStyle.Default, handler: { (action) -> Void in}))self.actionSheetController?.addAction(UIAlertAction(title: self.dataArray[3], style: UIAlertActionStyle.Default, handler: { (action) -> Void in}))self.actionSheetController?.addAction(UIAlertAction(title: self.dataArray[4], style: UIAlertActionStyle.Default, handler: { (action) -> Void in}))self.actionSheetController?.addAction(UIAlertAction(title: self.dataArray[5], style: UIAlertActionStyle.Default, handler: { (action) -> Void in}))self.actionSheetController?.addAction(UIAlertAction(title: self.dataArray[6], style: UIAlertActionStyle.Default, handler: { (action) -> Void in}))self.presentViewController(self.actionSheetController!, animated: true) { () -> Void in}}
}

说实在的和写java程序一样，是不是特别给力。

android 实现

然后下面是安卓来实现：

actionSheet.java

搞了下，很简单的代码也就不需要介绍了，下面直接上图看效果

我也是醉了，截屏工具出问题，手机拍照的
