How to read kmz file of google map in android

问题

I have the KMZ file and I want to parse that KMZ file so that I can read the data of that file I tried to use KmlLayer but didn't get any help from it here is my code

InputStream inputStream = new FileInputStream(path);
KmlLayer layer = new KmlLayer(mMap, inputStream, getApplicationContext());
layer.addLayerToMap();

but I got Parsing exception while I am creating the object of KmlLayer any solution.

回答1:

Because KMZ is zipped KML you should unzip .kmz file to .kml before reading data or use ZipInputStream instead of FileInputStream like in this createLayerFromKmz() method:

private KmlLayer createLayerFromKmz(String kmzFileName) {
    KmlLayer kmlLayer = null;

    InputStream inputStream;
    ZipInputStream zipInputStream;

    try {
        inputStream = new FileInputStream(kmzFileName);
        zipInputStream = new ZipInputStream(new BufferedInputStream(inputStream));
        ZipEntry zipEntry;

        while ((zipEntry = zipInputStream.getNextEntry()) != null) {
            if (!zipEntry.isDirectory()) {
                String fileName = zipEntry.getName();
                if (fileName.endsWith(".kml")) {
                    kmlLayer = new KmlLayer(mGoogleMap, zipInputStream, getApplicationContext());
                }
            }

            zipInputStream.closeEntry();
        }

        zipInputStream.close();
    }
    catch(IOException e)
    {
        e.printStackTrace();
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    }

    return kmlLayer;
}

And you can use it e.g. this way:

@Override
public void onMapReady(GoogleMap googleMap) {
    mGoogleMap = googleMap;

    // path to your kmz file 
    String kmzFileName = Environment.getExternalStorageDirectory() + "/KMZ/markers.kmz";
    try {
        KmlLayer kmlLayer = createFromKmz(kmzFileName);
        kmlLayer.addLayerToMap();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    }

}

NB! createLayerFromKmz() works only on "flat" KMZ structure.
