本文介绍了一个用于生成XML文件的Java类实例。该类通过构造函数初始化串行化器和字符串写入器，并创建设备信息对象。主要方法createXmlFile()负责生成包含测试结果和设备信息的XML文件。

1. 生成XML类：

public class WriteXml {

	String name = "http://www.w3.org/2001/XMLSchema-instance";
	String value = "http://www.w3.org/2001/XMLSchema";
	private XmlSerializer serializer;
	private StringWriter writer;
	private DevicesInfo devicesInfo;
	private String[] MeasurementData = { "Name", "Status", "Result", "LowerLimit", "UpperLimit", "Units", "CompType", "LogCount", "LogTime" };

	public WriteXml(Context context) {
		writer = new StringWriter();
		serializer = Xml.newSerializer();
		// serializer = new FastXmlSerializer();

		devicesInfo = new DevicesInfo(context);

		Test();
	}

	public String createXmlFile() {
		try {
			serializer.setOutput(writer);
			serializer.startDocument("UTF-8", true);
			serializer.setFeature("http://xmlpull.org/v1/doc/features.html#indent-output", true);
			serializer.startTag(null, "TestResults");
			serializer.attribute(null, "xmlns:xsi", name);
			serializer.attribute(null, "xmlns:xsd", value);

			createAllResult();
			createDevicesInfo();

			serializer.startTag(null, "TestDatas");
			Map<String, String> map0 = mList.get(0);
			Map<String, String> map1 = mList.get(1);
			createTestDatas(map0, "SAMPLER_SETUP_STATUS", "PASS", false);
			createTestDatas(map1, "ENUMERATION_STATUS", "PASS", false);
			createTestDatas(map1, "FUNCTIONS_TEST_RESULTS", "PASS", true);
			serializer.endTag(null, "TestDatas");

			serializer.endTag(null, "TestResults");
			serializer.endDocument();
			return writer.toString();
		} catch (Exception e) {
			throw new RuntimeException(e);
		}
	}

	private void createAllResult() {
		try {
			serializer.startTag(null, "OverallResult");
			serializer.startTag(null, "Result");
			serializer.text("PASS");
			serializer.endTag(null, "Result");
			serializer.startTag(null, "ErrorCode");
			serializer.text("NoError");
			serializer.endTag(null, "ErrorCode");
			serializer.startTag(null, "ErrorMessage");
			serializer.endTag(null, "ErrorMessage");
			serializer.startTag(null, "ErrorTestName");
			serializer.endTag(null, "ErrorTestName");
			serializer.startTag(null, "ErrorFullTestName");
			serializer.endTag(null, "ErrorFullTestName");
			serializer.startTag(null, "ErrorDetails");
			serializer.endTag(null, "ErrorDetails");
			serializer.endTag(null, "OverallResult");
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalStateException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	private void createDevicesInfo() {
		try {
			serializer.startTag(null, "UnitSerialNumber");
			serializer.text(devicesInfo.getSerialNumber());
			serializer.endTag(null, "UnitSerialNumber");
			serializer.startTag(null, "StartDate");
			serializer.text(devicesInfo.getCurrentTime());
			serializer.endTag(null, "StartDate");
			serializer.startTag(null, "StopDate");
			serializer.text(devicesInfo.getCurrentTime());
			serializer.endTag(null, "StopDate");
			serializer.startTag(null, "ModelName");
			serializer.text(devicesInfo.getModelName());
			serializer.endTag(null, "ModelName");
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalStateException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	private void createTestDatas(Map<String, String> map, String name, String status, boolean isloop) {
		try {
			serializer.startTag(null, "TestData");
			serializer.attribute(null, "Name", name);
			serializer.attribute(null, "Status", status);
			serializer.startTag(null, "Measurements");
			if (isloop) {
				for (int i = 0; i < 9; i++) {
					serializer.startTag(null, "MeasurementData");
					createMeasurementData(map);
					serializer.endTag(null, "MeasurementData");
				}
			} else {
				serializer.startTag(null, "MeasurementData");
				createMeasurementData(map);
				serializer.endTag(null, "MeasurementData");
			}

			serializer.endTag(null, "Measurements");
			serializer.endTag(null, "TestData");
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalStateException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	private void createMeasurementData(Map<String, String> map) {
		try {
			for (int i = 0; i < 9; i++) {
				serializer.attribute(null, MeasurementData[i], map.get(MeasurementData[i]));
			}
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalStateException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	ArrayList<Map<String, String>> mList = new ArrayList<Map<String, String>>();

	private void Test() {
		for (int j = 0; j < 2; j++) {
			Map<String, String> map = new HashMap<String, String>();
			for (int i = 0; i < 9; i++) {
				map.put(MeasurementData[i], devicesInfo.getData(i));
			}
			mList.add(map);
		}
	}
}

2. 获取属性类：

public class DevicesInfo {
	private Context context;

	public DevicesInfo(Context context) {
		this.context = context;
		
		initData();
	}

	public String getSerialNumber() {
		return android.os.Build.SERIAL;
	}

	public String getModelName() {
		return android.os.Build.MODEL;
	}

	public String getCurrentTime() {
		SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss.ssssss");
		return sDateFormat.format(new java.util.Date());
	}

	// String[] data = {"STATUS","PASS","NoError","NoError","NoError","None","EQ","0",""};

	String[] data = new String[9];

	private void initData() {
		for (int i = 0; i < data.length; i++) {

			switch (i) {
			case 0:
				data[i] = "STATUS";
				break;
			case 1:
				data[i] = "PASS";
				break;
			case 2:
				data[i] = "NoError";
				break;
			case 3:
				data[i] = "NoError";
				break;
			case 4:
				data[i] = "NoError";
				break;
			case 5:
				data[i] = "None";
				break;
			case 6:
				data[i] = "EQ";
				break;
			case 7:
				data[i] = "0";
				break;
			case 8:
				data[i] = getCurrentTime();
				break;
			}
		}
	}
	
	public String getData(int i){
		return data[i];
	}
}

3.写成文件：

public boolean WriteFileData(String dirPath, String str) {
		OutputStream out = null;
		try {
			File f = new File(dirPath);
			out = new FileOutputStream(f);
		} catch (Exception e) {
			return false;
		}
		OutputStreamWriter outw = new OutputStreamWriter(out);
		try {
			outw.write(str);
			outw.close();
			out.close();
		} catch (Exception e) {
			return false;
		}
		return true;
	}
