我在ViewPager中有一个ViewPager,我得到了这个例外

我刚刚下载了Android 3.0 SDK并用它启动了一个模拟器.我用Ctrl-F12将模拟器旋转到纵向模式,然后打开,用2.2和整个模拟器构建的活动是颠倒的(因为模拟器是倒置的,主页按钮位于顶部,屏幕是颠倒的) .有没有办法以另一种方式旋转它或者我完全错过了什么？(我已经尝试过按Ctrl-F11或Num pad,结果相同)

我有一个Android WebView,其JavaScript通过addJavascriptInterface方法调用Android方法:

myWebview.addJavascriptInterface(new JavascriptBridge(), "Android");

public class JavascriptBridge {

    public String getAString() {          
        return "my_str";
    }
}

这很好用.我想将一个int列表返回给WebView.试过这个:

public class JavascriptBridge {

    public int[] getMyInts() {          
        return new int[]{1,2,3};
    }
}

但是在JS中调用此函数会返回undefined:

var myInts = Android.getMyInts();

是否有Android Javascript界面​​的有效返回类型列表？它只是原始人吗？

如果我为cloudfront执行自定义源并且返回set-cookie标头,那么cloudfront会为响应缓存set-cookie标头吗？如果没有,是否会有CDN？

我有一个android项目,它有一个测试模块,可以在git目录的子目录中删除并重新创建.apk文件.

我已将这些添加到.gitignore(目录,显式文件和*.apk),然后我就完成了

git rm -r --cached src/main/Tests/bin

和git告诉我:

rm 'src/main/Tests/bin/Tests-debug-unaligned.apk'
rm 'src/main/Tests/bin/Tests-debug.apk'
rm 'src/main/Tests/bin/Tests.ap_'
rm 'src/main/Tests/bin/classes.dex'

我然后

git commit . -m "removed apk files"

我再次运行测试,删除文件并重新创建它们.我运行git status并显示为已修改.看来.gitignore没有用.这是我的.gitignore文件

*ipr
*iml
*iws
.gitignore
out/
*apk
src/main/Tests/bin
src/main/Tests/bin/*
src/main/Tests/bin/Tests-debug-unaligned.apk

Sinatra是所有标题名称的骆驼套管,导致'P3P'出现问题.码:

require 'rubygems'
require 'sinatra'

configure :production do
  # Configure stuff here you'll want to
  # only be run at Heroku at boot

  # TIP:  You can get you database information
  #       from ENV['DATABASE_URI'] (see /env route below) 
end

# Quick test
get '/track' do
  #response.headers['Cache-Control'] = 'public, max-age=300'
  response.set_cookie("visited",1)
  response['this-that'] = "CP=\"CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE\""
  response['P3P'] = "CP=\"CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL …

ImageMagick将gif分成jpgs,但其中一些有白色像素,有些则没有.

convert -strip tree.gif tree.jpg

将gif拆分为86 jpgs.这是#68和#69.

#68

和#69

和有问题的GIF:

约1/3有类似的编码问题.

我正在使用Imagemagick将gif转换为相应的jpgs系列,我试图确定每个jpg何时发生在一个系列中.

被盗如何检测每秒动画GIF的刻度？:identify -format "%T ticks: %f: Frame[%s] %m %wx%h %P%O %r %z-bit\n" tree.gif

我正在尝试模拟一个SimpleDateFormat对象，但 Mockito 说我的参数数量错误。代码：

 SimpleDateFormat spyDateFormat = spy(new SimpleDateFormat(DateFormatManager.MAIN_ACTIVITY_TITLE_FORMAT));
 // exception points to below line
 when(spyDateFormat.format(any(Date.class))).thenReturn("foo format");

例外：

org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Invalid use of argument matchers!
3 matchers expected, 1 recorded:

该方法存在于其父 DateFormat 中：

http://docs.oracle.com/javase/7/docs/api/java/text/DateFormat.html#format(java.util.Date)

尝试切换到 DateFormat，使用spy. 没有运气。

我有一个模拟器,我想模拟在我的应用程序中丢失数据连接.我正确设置了接收器,但我需要一种通过adb更改数据连接的方法.

是否有ADB命令关闭数据连接？
