format

I want the number being displayed in my EditText upto 1 decimal place with no leading zeroes e.g. 25.0 not like 025.0 how can i do this? this is in android You can use DecimalFormat DecimalFormat format = new DecimalFormat("##.#"); String formattedText = format.format(025.0); editText.setText(formattedText); You will get result in EditText as 25.0 you can set it in xml file. Like <EditText android:id="@+id/editText1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/imageView1" android:layout_below="@+id/imageView1" android:layout

笔者的hadoop在不间断的写文件的过程中报了如下错误 经查看发现是hadoop所在服务器的磁盘空间不足导致的。 好了，知道问题后笔者需要配置相关参数来避免该问题 1、与mapred.local.dir相关的参数 * mapred.local.dir.minspacestart：在mapreduce运行任务之前，检查temporary 目录下是否还有该选项配置的空闲空间，如果少于该配置，则map或reduce task不会分配到该TaskTracker上，以避免由于磁盘空间不足导致的task失败。默认设置为0，disable该功能 * mapred.local.dir.minspacekill：如果该磁盘卷下剩余的磁盘空间不足该配置，则将正在运行的Task 杀掉。默认为0，diabled该功能 另，如果服务器有多个块设备最好将mapred.local.dir设置成多个目录，每个目录对应一个块设备，这样多个task在同一个TaskTracker上运行的时候，就可以分别写不同的磁盘写入点，以增大作业运行的磁盘吞吐率。 2、与dfs.data.dir相关的参数 * dfs.datanode.du.reserved：dfs写文件块时，如果当前datanode上的dfs.data.dir下剩余磁盘空间不足该选项配置的空间大小，就不往该datanode继续写数据块 * dfs.datanode

I wrote the following file in Visual Studio 2008 as a new XML file, and it reports the following error. What is the error message about and why it is treated as a wrong format XML file? Here is the XML file and related error message. <?xml version="1.0" encoding="utf-8"?> <Foo>&#x2;</Foo> Error 1 Character ' ', hexadecimal value 0x2 is illegal in XML documents. XMLFile1.xml 2 6 Miscellaneous Files thanks in avdance, George Your problem is the reference to &#x02, which essentially is random binary data that can not be printed. This is not allowed in XML1.0 (it is in XML 1.1 and higher, but it's

I'm writing a java program to import private keys from files within the file system and make a private key object, using java... I could do it for files in .pem format but, with .der format, I had no idea what to do, since I couldnt firstly detect the algorithm used to generate the keys. within .pem files I could determine the algorithm from the header for PKCS#1 which have a header like -----BEGIN RSA PRIVATE KEY---- formats and used the bouncycastle pem reader for those in PKCS#8 which have a header -----BEGIN PRIVATE KEY----- but with those in .der format no idea :( also if anyone have an

I have this function: void Log::Write(string logline){ //2011-10-12 13:07:40 correct format time_t rawtime; struct tm * timeinfo; time ( &rawtime ); timeinfo = localtime ( &rawtime ); m_stream.write( asctime (timeinfo), 24 ); m_stream << " - " << logline << std::endl; } The output is like this: Thu Oct 13 12:35:30 2011 but I wanna see the output like the comment section: 2011-10-12 13:07:40 How is it possible? It's very possible. Look at the manpage for strftime() . In this case, you'd want: void Log::Write(string line) { time_t rawtime; struct tm * timeinfo; char buffer [80]; time ( &rawtime
