Android中组装xml文件内容
下面这段xml文件内容是我们的需求。
1. <?xml version='1.0' encoding='utf-8' standalone='no' ?>
2. <persons>
3. <person key="one">
4. <name>zhangsan</name>
5. <age>26</age>
6. </person>
7. <person key="two">
8. <name>lisi</name>
9. <age>25</age>
10. </person>
11. </persons>
下面是组装xml文件内容的代码。
[java] view plaincopy

3. import android.os.Bundle;
4. import android.util.Log;
5. import android.util.Xml;
6. import java.io.IOException;
7. import java.io.StringWriter;

9. public class MainActivity extends Activity {
10.
11. public static final String TAG = "MainActivity";
12.
13. @Override
14. public void onCreate(Bundle savedInstanceState) {
15. super.onCreate(savedInstanceState);
16. setContentView(R.layout.activity_main);
17.
18. Log.d(TAG, createXMLData());
19. }
20.
21. /**
22. * create xml data
23. *
24. * @return
25. */
26. protected String createXMLData() {
27.
28. XmlSerializer serializer = Xml.newSerializer();
29. StringWriter stringWriter = new StringWriter();
30.
31. try {
32. serializer.setOutput(stringWriter);
33. serializer.startDocument("utf-8", false);
34. // start persons
35. serializer.startTag(null, "persons");
36.
37. // one
38. serializer.startTag(null, "person");
39. serializer.attribute(null, "key", "one");
40.

67.
68. serializer.endDocument();
69.
70. } catch (IOException e) {
71. e.printStackTrace();
72. }
73. return stringWriter.toString();
74. }
75. }
