Question

I am using a SAX XML Parser to get values out of a XML file that works fine. This is the method in my main activity:

public void parseXML() {

    String parsedData = "";

    try {

        Log.w("AndroidParseXMLActivity", "Start");
        /** Handling XML */
        SAXParserFactory spf = SAXParserFactory.newInstance();
        SAXParser sp = spf.newSAXParser();
        XMLReader xr = sp.getXMLReader();

        XMLContentHandler myXMLHandler = new XMLContentHandler();
        xr.setContentHandler(myXMLHandler);

        AssetManager assetManager = getAssets();
        InputStream inputStream = null;
        try {
            inputStream = assetManager.open("calimero.xml");
        } catch (IOException e) {
            Log.e("tag", e.getMessage());
        }
        xr.parse(new InputSource(inputStream)); 

        ArrayList<Datapoint> itemsList = myXMLHandler.getItemsList();
        int datapoint_size = itemsList.size();
        String xml_names[]  = new String [datapoint_size];
        String xml_states[]  = new String [datapoint_size];
        String xml_dptIDs[] = new String [datapoint_size];
        String xml_groupadresses[]  = new String [datapoint_size];
        String xml_mainNumbers[]  = new String [datapoint_size];

        for(int i=0;i<itemsList.size();i++){
            Datapoint item = itemsList.get(i);
            parsedData = parsedData + "----->\n";
            parsedData = parsedData + "Name: " + item.getName() + "\n";
            xml_names[i] = item.getName();
            parsedData = parsedData + "stateBased: " + item.getStateBased() + "\n";
            xml_states[i] = item.getStateBased();
            parsedData = parsedData + "mainNumber: " + item.getMainNumber() + "\n";
            xml_mainNumbers[i] = item.getMainNumber();
            parsedData = parsedData + "dptID: "+ item.getDptID() + "\n";
            xml_dptIDs[i] = item.getDptID();
            parsedData = parsedData + "Groupadress: "+ item.getGroupadress() + "\n";
            xml_groupadresses[i] = item.getGroupadress();
        }
        Log.w("AndroidParseXMLActivity", "Done");
    }
    catch (Exception e) {
        Log.w("AndroidParseXMLActivity",e );
    }
    Log.w("AndroidParseXMLActivity", names[0]);
    Log.w("AndroidParseXMLActivity", mainNumbers[2]);
    Log.w("AndroidParseXMLActivity", dptIDs[3]);
    //xmlOutput.setText(parsedData);
}

I want to use the values like name, mainNumber and so on outside my method. But I don’t get it… I know this are java basic….
Please help me, thanks!

If you want to use your String array in the whole class you have to define it in the class. Then the variable are avaliable for all functions in your class.

    public class Test {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        StringArray testString = new StringArray();
        testString.setArray();
        testString.printArray();
    }

    static private class StringArray{
        String test[];

        public void setArray(){
            test = new String[5];
            for (int i = 0 ; i < test.length; i++){
                test[i] = "test";
            }
        }

        public void printArray(){
            for (int i = 0 ; i < test.length; i++){
                System.out.println(test[i]);
            }
        }
    }
}
