我试图创建MATCH_PARENT宽度的DialogFragment这样的对话框几乎全屏幕(离开填充周围的边缘为流动的样子).我在Android中看到过这个解决方案Full Screen DialogFragment,但我试图避免将宽度设置为1000dp的黑客攻击.以我目前的布局,我是使用FILL_PARENT或MATCH_PARENT它似乎是设置宽度和高度WRAP_CONTENT.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
我已经将此解决方案用于Dialog(而不是DialogFragment),它按预期工作:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
我正在构建自定义安装程序.如何在开始菜单中创建可执行文件的快捷方式？这是我到目前为止所提出的:
string pathToExe = @"C:\Program Files (x86)\TestApp\TestApp.exe";
string commonStartMenuPath = Environment.GetFolderPath(Environment.SpecialFolder.CommonStartMenu);
string appStartMenuPath = Path.Combine(commonStartMenuPath, "Programs", "TestApp");
// TODO: create shortcut in appStartMenuPath
我的目标是Windows 7.
最近我在Eclipse中的内容辅助方面遇到了越来越多的问题.在我的一些项目中,我没有从内容协助中获得任何提议,而在其他项目中,我得到了部分或全部预期提案.通常,Eclipse中没有"错误",但是当我收到错误时,这是一个示例:
"内容辅助"没有正常完成.有关更多信息,请参阅日志.铅(324)式android.support.v4.app.LoaderManager $ LoaderCallbacks不能得到解决.它是从所需的.class文件间接引用的
我已经尝试了类似问题的各种建议(包括但不限于以下两个),没有运气.我甚至没有删除和重新安装eclipse并重新创建项目而没有任何Eclipse元数据或设置.
任何帮助是极大的赞赏.

我正在尝试将我的Android项目从eclipse迁移到Android Studio.安装最新的Android Studio和Gradle后,我按照http://developer.android.com/sdk/installing/migrate.html上的说明进行操作.当我尝试导入主项目时,我收到此错误:
Could not fetch model of type 'IdeaProject' using Gradle installation 'C:\gradle-1.6'.
Settings file 'C:\P4\java\EIQBlackberry\workspace\settings.gradle' line: 1
A problem occurred evaluating settings 'workspace'.

这就是我的settings.gradle样子:
include ':C::P4:java:EIQBlackberry:workspace:ActionBarSherlock4'
include ':C::P4:java:EIQBlackberry:workspace:ViewPagerIndicatorSherlock'
... (a few more include lines just like the above for the other projects)
有什么建议？

我正在寻找一种方法,使用Microsoft.Web.Administration.dll在IIS 7中添加处理程序映射.有没有我可以在ServerManager对象上使用的方法？
如果通过GUI添加,这些是要遵循的步骤,但同样,我需要以编程方式完成此操作.http://coderock.net/how-to-create-a-handler-mapping-for-an-asp-net-iis-7-with-application-running-in-integrated-mode/
这是我用来启用ISAPI限制的代码,处理程序映射是否有类似的东西？

addElement["path"] = path;
addElement["allowed"] = isAllowed;
addElement["description"] = description;
