我想在android中使用形状绘制水平和垂直虚线.

我想这样画

对于水平线

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line" >

    <stroke
        android:dashGap="6px"
        android:dashWidth="6px"
        android:color="#C7B299" />

</shape>

对于垂直线

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line" >
<size
     android:height="400dp"/>
    <stroke
        android:dashGap="6px"
        android:dashWidth="6px"
        android:color="#C7B299" />

</shape>

但不显示我的输出的垂直虚线显示如下

如何绘制垂直线.

我在自己的UI设计中使用了自动布局的故事板.在android中基本上有三种不同的属性,如Visible,Invisible和不见了.

例如:

   1) android:visibility="gone" // used to hide the control and as well as space
      (or)
      CONTROLNAME.setVisibility(View.GONE);
   2)  android:visibility="invisible" // used to hide the control but it will take space
      (or)
      CONTROLNAME.setVisibility(View.INVISIBLE);

在IOS,

Objective-C的

  1) ?
  2) [CONTROLNAME setHidden:TRUE]; // used to hide the control but it will take space

迅速

  1) ?
  2) CONTROLNAME.isHidden = true  // used to hide the control but it will take space

作为IOS 消失的行为我从谷歌搜索但我无法找到解决方案.

该示例显示:

我创建一个简单的模块(斐波那契计算器)我启动pycharm控制台,导入模块,在控制台内运行函数,它的工作原理.现在我在模块中编辑一些打印文本.回到控制台并运行"import fibagain"
控制台似乎没有抱怨就这样做了.但是当我运行fib()函数时,它仍然给我早期版本的结果.我无法让控制台看到fibagain.py文件的更新版本.如果我删除控制台并再次打开它,那么'import fibagain',运行fib(3)将给我最新版本.

抱歉,但不允许在此处发布正确的图片链接.这个地址显示了screencapture:

我想在iOS7上设置NSString的背景cornerRadius.但是,NSString没有图层......

请告诉我,如何在iOS7上设置NSString的背景cornerRadius？

我正在使用Microsoft aad:adal4j来处理来自Mobile的动态crm登录.实施后我得到以下例外.

我究竟做错了什么？

像上面的代码一样,标题中的默认日期格式将是MM/dd/yyyy,但我需要修改该格式.

retrieve.php

<?php
  $data = file_get_contents('php://input');
  header('Location: http://192.168.12.45/enroll/info?'.$data, true, 301);
?>

info是一个目录,而不是一个页面,我在这个目录中创建了index.php,我在$ _GET中获取了数据.

但我能从php获得.

但我想使用java servlet,我在servlet url上的mobileconfig文件中更改了url,但我无法在java中获取任何值.

检索Java代码

    Enumeration headerNames = request.getHeaderNames();
    while (headerNames.hasMoreElements()) { …

我有一个tweeter json(保存在一个名为latest.json的文件中),我解析为"jasonvalue doc",我尝试读取它并打印特定数据.下面的代码每次打印相同的数据,而不是数据形成整个json.

auto content = to!string(read("latest.json"));
 JSONValue doc = parseJSON(content).object; 
 while (i<3){
    writeln(doc.object["created_at"].str,"\n");
    writeln(doc.object["text"].str,"\n");
    writeln(doc.object["retweet_count"].integer,"\n");
    i++;
 }

我怎么能读到所有的杰森？

我想设计一个像这样的登录页面

在采用箱阴影在IOS当前页我试图层阴影像这样 但是这一个未示出像上述图像PLZ指南.

我试过了

imageView.layer.shadowColor = [UIColor purpleColor].CGColor;
imageView.layer.shadowOffset = CGSizeMake(0, 1);
imageView.layer.shadowOpacity = 1;
imageView.layer.shadowRadius = 1.0;
imageView.clipsToBounds = NO;

但它表明

提前致谢

更新

使用holex代码:

UIImageView *imag = (UIImageView*)[self.view viewWithTag:1];
    imag = [[UIImageView alloc] initWithFrame:CGRectMake((screenWidth/100)*12, (screenHeight/100)*10, (screenWidth/100)*75, (screenHeight/100)*61)];
    [imag setBackgroundColor:[UIColor whiteColor]];
    [imag.layer setOpacity:0.4];
    [imag.layer setShadowOpacity:1.0];
    [imag.layer setShadowColor:[[UIColor blackColor] CGColor]];
    [imag.layer setShadowOffset:CGSizeMake(0.0, 0.0)];
    [imag.layer setShadowRadius:8.0];
    [imag setClipsToBounds:FALSE];
    [imag.layer setMasksToBounds:FALSE];
    [self.view addSubview:imag];

ios 6它显示如下图像,但它在ios 7上工作

我试图使用forceStopPackage()杀死另一个应用程序.但我的应用程序显示运行时错

错误:

java.lang.SecurityException: Permission Denial: forceStopPackage() from pid=10377, uid=10200 requires android.permission.FORCE_STOP_PACKAGES

在我的清单文件中,我添加了以下权限.

<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />

    <permission
        android:name="android.permission.FORCE_STOP_PACKAGES"
        android:permissionGroup="android.permission-group.SYSTEM_TOOLS"
        android:protectionLevel="signature"
        android:sharedUserId="android.uid.system" />

代码:

ActivityManager am = (ActivityManager) 
         context.getSystemService(Context.ACTIVITY_SERVICE);
Method forceStopPackage = am.getClass().
          getDeclaredMethod("forceStopPackage", String.class);  
    forceStopPackage.setAccessible(true);  
    forceStopPackage.invoke(am, packageName);

如何解决问题.

我需要在iPhone模拟器上安装.ipa文件.

我试图将扩展名.ipa更改为.zip并将其解压缩.

我收到Payload文件夹并将应用程序内部移动到我的iPhone模拟器应用程序文件夹中:

 /Library/Application\ Support/iPhone Simulator/6.1/Applications/

应用程序出现在iPhone模拟器上,但应用程序没有运行.如何解决问题然后如何运行应用程序.
