Hello ,
developing application with form having multiple fields, at the end
user need to submit the information.
On this event, all the data need to be stored in XML file.
thus XML write is required. plus when user asks for particular id then
the data filled by that id is also to be displayed thus XML read is
required.(search operation)
Following is the code I tried for generating sample xml.
/////////////////////////////////////////////////////////////////////////////////////////////
FileOutputStream fileos = null;
try{
fileos=openFileOutput("newxml.xml",Context.MODE_PRIVATE);
Log.v("info","fileoutput open");
// fileos = new
FileOutputStream(newxmlfile);
}catch(FileNotFoundException e){
Log.e("FileNotFoundException", "can't
create
FileOutputStream");
}
// create a XmlSerializer in order to write xml
data
XmlSerializer serializer = Xml.newSerializer();
try {
//we set the FileOutputStream as output
for the
serializer, using UTF-8 encoding
serializer.setOutput(fileos,
"UTF-8");
//Write <?xml declaration with
encoding (if encoding not null)
and standalone flag (if standalone not null)
serializer.startDocument(null,
Boolean.valueOf(true));
//set indentation option
//serializer.setFeature("http://xmlpull.org/v1/doc/
features.html#indent-output", true);
//start a tag called "root"
serializer.startTag(null,
"root");
//i indent code just to have a
view similar to xml-tree
serializer.startTag(null, "child1");
serializer.endTag(null,
"child1");
serializer.startTag(null, "child2");
//set an attribute
called "attribute" with a "value" for
<child2>
serializer.attribute(null, "attribute", "value");
serializer.endTag(null,
"child2");
serializer.startTag(null, "child3");
//write some text
inside <child3>
serializer.text("some
text inside child3");
serializer.endTag(null,
"child3");
serializer.endTag(null, "root");
serializer.endDocument();
//write xml data into the
FileOutputStream
serializer.flush();
//finally we close the file
stream
fileos.close();
//TextView tv =
(TextView)this.findViewById(R.id.result);
//tv.setText("file has been
created on SD card");
Log.v("info","file has been
created on SD card");
return true;
} catch (Exception e) {
Log.e("Exception","error
occurred while creating xml file");
return false;
}
//////////////////////////////////////////////////////////////////////////////////////////////////////
executed this with actual device but, no new xml file is created.
where to store this programatically created xml file?
On emulator if I want to test this application, where the xml file
will get stored?
Pls guide me whats going wrong?
Thanks.
