在Java中,我如何将StringBuffer转换为字节数组？

<a4j:ajax event="click" render="tempval" listener="#{question.setParameters}" />

当我们使用此代码时,服务器会抛出该消息的异常

#{...} is not allowed in template text

这是怎么造成的,我该如何解决？

我想访问与View Pager附加的子片段中的父片段视图.意味着父片段包含一个视图寻呼机和视图寻呼机然后有一个片段,我想在当前的寻呼机片段中使用父片段视图.

父片段---->(包含)查看寻呼机------>(包含)子片段.Child Fragment想要使用Parent Fragment多个视图.请提出任何解决方案.

提前致谢.

我在Android中实现了一个群聊机制,我通过Openfire的REST API插件创建了群组并添加了成员​​.将消息发送到同一组但不向同一组的所有成员发送消息.请查看我的错误日志,并建议我有任何相同的解决方案.

我有一个问题,我想获得在视频视图中运行的视频的总长度我使用视频视图的getDuration方法但是当我将它与currentPosition进行比较时它总是返回-1.实际上我想要的是,如果视频的当前位置等于视频的总长度,那么它应该从第0位开始意味着开始.意思是我想说我想比较视频当前位置和视频的总长度,我该怎么做？

提前致谢.

码:

videoPosition=VideoPositionFinding(IDValue,video.getDuration());
    video.seekTo(videoPosition);
    if(video.getCurrentPosition()==video.getDuration()){
        videoPosition=0;
    }
     locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
     System.out.println("The Video Duration: "+video.getCurrentPosition());

     video.start();

我在网格视图的标题中添加一个按钮,但Visual Studio突出显示这个错误:

'EVAL名称在当前上下文中不存在'.

为什么会发生这种情况,如何解决？

 <asp:gridview  runat="server" >    
      <Columns>
         .....
         <asp:TemplateField>
             <ItemTemplate>
                  <asp:Literal runat="server" ID="litFamily" Text='<%# EVAL("CompanyAddress") %>'></asp:Literal>

可能重复:
SMTP服务器需要安全连接或客户端未经过身份验证.服务器响应为:5.5.1需要身份验证

我运行此代码时出现问题,然后发生错误"SMTP服务器需要安全连接或客户端未经过身份验证.服务器响应为:5.5.1需要身份验证."

我的代码是:
