小编Pan*_*thu的帖子

我正在研究一个Android教程,它希望我从另一个项目中导入库.导入工作正常,项目正常工作.但是我注意到,这样做会搞砸我的其他几个项目(那些使用Android 2.1的项目),显然是搞乱了构建路径.现在,而不是在gen我看到的文件夹下看到"Google API [Android 2.1]" "Unable to get system library for project".

我验证了以下内容:

我右键单击了该项目并转到Properties我看到正确的项目构建目标被选中(Google API [Android 2.1]),但"无法获取项目的系统库"仍然显示在assets文件夹上方和gen和Android下方依赖.清理所有项目没有帮助.

我该如何解决这个问题？有没有办法在全球范围内解决这个问题,还是我必须逐个解决这个问题？

我正在使用Retrofit来处理来自Mobile的Serverside数据.实施改造后,我得到以下例外.

我究竟做错了什么？

如何以编程方式使用EPPlus更改Excel饼图的默认颜色.

下面是我的代码

var pieChart = worksheet.Drawings.AddChart("piechart", eChartType.Pie3D) as ExcelPieChart;
            //Set top left corner to row 1 column 2
            pieChart.SetPosition(18, 0, 0, 0);
            pieChart.SetSize(350, 300);
            pieChart.Series.Add(ExcelRange.GetAddress(12, 2, 15, 2),ExcelRange.GetAddress(12, 1, 15, 1) );
            pieChart.Legend.Position = eLegendPosition.Bottom;
            pieChart.Legend.Border.Fill.Color = Color.Green;
            pieChart.Legend.Border.LineStyle = eLineStyle.Solid;              
            pieChart.Legend.Border.Fill.Style = eFillStyle.SolidFill;
            pieChart.Title.Text = "Current Status";               
            pieChart.DataLabel.ShowCategory = false;
            pieChart.DataLabel.ShowPercent = true;

我想将默认颜色更改为一些明亮的颜色.

建议并对此进行一些说明.

这是我的HTML

<script src="/ClientScripts/swfobject.js" language="javascript" type="text/javascript"> </script>
<div class="contentDetails">
<div id="ctl00_MainContentPlaceHolder_ContentDetailsBodyDivision" class="body">
<div align="justify">

<p align="center"><img width="500" height="352" alt="MVM315" src="/UserUpload/Image/1(825).jpg" /></p>
<p align="center"><img width="500" height="352" alt="MVM315" src="/UserUpload/Image/2(598).jpg" /></p>

我如何src="/UserUpload/Image/1(825).jpg"用jsoup 获得{ }？

我有这个代码,但没有工作

Document doc = Jsoup.parse(html);
Elements mElements = doc.select("div[id^=ctl00_MainContentPlaceHolder_ContentDetailsBodyDivision]");
Result = mElements.get(0).tagName("img").toString();

Solr有一个Admin UI,我们可以在其中检查部署到Solr Cloud的每个集合.例如,我可以在集合中看到Slice/Shard,如下面的URL中所述.

出于安全原因,我们的生产环境不提供对此管理UI的访问.我需要提供一个API来获取每个集合的状态,以及它的分片和每个分片的副本.我正在使用Solr API来做到这一点

http://lucene.apache.org/solr/4_7_2/solr-solrj/index.html

CloudSolrServer server = new CloudSolrServer(<zk quorum>);
ZkStateReader reader = server.getZkStateReader();
Collection<Slice> slices = reader.getClusterState().getSlices(collection);
Iterator<Slice> iter = slices.iterator();
while (iter.hasNext()) {
    Slice slice = iter.next();
    System.out.println(slice.getName());
    System.out.println(slice.getState());
}

上面的代码总是仅作为分片的状态返回Active,甚至它的副本在UI中显示.我假设这只返回分片的状态,而不是分片的领导者或副本的状态.

如何通过Solr API获取副本状态？这有什么API吗？Solr Admin UI正在使用什么API来获取分片的副本/领导者状态？

谢谢
