KmlParser.Java
使用XMLSerializer创建KML文件，但不将其保存在android内部存储中。我不知道在创建文件还是仅保存在内部存储中是否有问题。任何人请帮助。可以节省我的时间。谢谢。
public class KmlParser {
private FileOutputStream fileos = null;
private XmlSerializer xmlSerializer;
File file;
public void writeKml(Context ctx, ArrayList<Double> coor_la, ArrayList<Double> coor_lo) {
//StringBuilder sb1 = new StringBuilder();
StringBuilder sb = new StringBuilder();
try {
File myDir = ctx.getDir("KML",Context.MODE_PRIVATE);
file = new File(myDir, "LandMap.kml");
//file.createNewFile();
//fileos = new FileOutputStream(file);
fileos = ctx.openFileOutput("LandMap.kml", Context.MODE_PRIVATE);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
// Here begins the KML creation
try {
xmlSerializer = XmlPullParserFactory.newInstance().newSerializer();
} catch (XmlPullParserException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
//Toast.makeText(PathGoogleMapActivity.this, "Error en serializer", Toast.LENGTH_SHORT).show();
}
try {
/* This KML file has a really basic structure, if you need
* styles and other fancy stuff, you are always free to add
* those style lines or anything you might need in order to

我不知道创建KML文件是否正确。我只是在StackOverflow中阅读过。
