我想要一个简单的网页启动并运行,它使用TreeView以及SiteMapDataSource.TreeView用于列出Web应用程序上的链接.我的网站导航数据源是XML文件(Web.sitemap).

当我在我的Web浏览器中运行此应用程序时,我收到错误:"无法连接到任何指定的MySQL主机."

它说我的错误在285行:

Line 283:    <siteMap>
Line 284:      <providers>
Line 285:        <add name="MySqlSiteMapProvider" type="MySql.Web.SiteMap.MySqlSiteMapProvider, MySql.Web, Version=6.9.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="LocalMySqlServer" applicationName="/" />
Line 286:      </providers>
Line 287:    </siteMap>

源文件:C:\ Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config行:285

我没有使用MySQL或任何RDBMS作为我的站点地图,所以我不确定为什么我会收到此错误.我在我的系统上安装了MySQL,以及Visual Studio 2015的插件,所以这可能是问题吗？

谢谢.

我最近将Android Studio从1.5升级到2.0.我的应用程序将在Android 1.5上构建并运行良好.现在,当我尝试在智能手机上运行应用程序时,它会给我这个错误:

Error:Execution failed for task ':app:transformClassesWithInstantRunForDebug'.
> 24

在Android Studio 2.0上打开我的项目时,会出现一个消息框,告诉我将我的gradle升级到版本2,我做了.我不知道为什么我会收到这个错误.

这是我尝试在手机上运行应用程序时获得的输出:

我最近将ExoPlayer添加到了我的Android项目中。有了他们的网站，设置它并播放音频剪辑相对简单。我可以从我的API中获取音频文件并进行播放，但是问题是，播放开始后PlayerControlView消失了。有没有一种方法可以强制PlayerControlView在音频剪辑的整个播放过程中停留？这是包含PlayerControlView的片段的XML：

我正在尝试在 TabLayout 中设置两个选项卡。第一个选项卡是显示配置文件，第二个选项卡是显示活动。我有 TabLayout 和 ViewPager 设置。我还创建了将两个片段链接到 tablayout 所需的适配器。当我在我的手机上运行它时，两个屏幕和选项卡会显示，但它们不会显示在选项卡区域内 - 它们覆盖了实际的选项卡。我正在使用设计支持库 (v23.1.1)

我有一个带有片段区域的主活动文件，它根据用户想要做什么来改变视图。

我该怎么做才能让标签内容显示在标签内部而不是标签顶部？这是我的代码：

编辑：这是 profile_fragment.xml 文件（这是我希望选项卡出现的地方）：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:app="http://schemas.android.com/apk/res-auto"
         xmlns:tools="http://schemas.android.com/tools"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         tools:context="Fragments.ProfileFragment">

<!-- TODO: Update blank fragment layout -->

    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id = "@+id/ProfileTabLayout"

    app:tabGravity="fill"
    app:tabMode="fixed"
    app:tabTextColor="@color/colorIcons"
