XmlPullParser mit eigenem Adapter

theAydinator · 2013-08-29T22:41:32+0200

Hallo lieber Forum,

bin neu hier und ich hoffe und wünsche mir,
dass ich hier dazulerne.

In meinem Skript versuche ich eine XML Datei (res/xml) mit Hilfe eines custom Adapters in eine Liste zu laden.

EmployeeXmlParser.java

Code:

package de.jfd.xmlparsing;

import java.io.IOException;
import java.util.ArrayList;
 
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
 
import android.content.Context;
 
public class EmployeeXmlParser {
 
    // names of the XML tags
    static final String BITTGEBETE = "bittgebete";
    static final String BITTGEBET = "bittgebet";
    static final String ID = "id";
    static final String NAME = "name";
    static final String AR = "ar";
    static final String DE = "de";
    static final String QUELLE = "quelle";
 
    ArrayList<Bittgebete> bittgebeteList = null;
    private Bittgebete currentBittgebet = null;
    private boolean done = false;
    private String currentTag = null;
 
    public ArrayList<Bittgebete> parse(Context context) {
 
        XmlPullParser parser = context.getResources().getXml(R.xml.hisnulmuslim);
 
        try {
 
            int eventType = parser.getEventType();
 
            // Following logic modified from http://www.ibm.com/developerworks/library/x-android/
            // Also look at http://developer.android.com/training/basics/network-ops/xml.html
 
            while (eventType != XmlPullParser.END_DOCUMENT && !done) {
 
                switch (eventType) {
                case XmlPullParser.START_DOCUMENT:
                    bittgebeteList = new ArrayList<Bittgebete>();
                    break;
                case XmlPullParser.START_TAG:
                    currentTag = parser.getName();
                    if (currentTag.equalsIgnoreCase(BITTGEBET)) {
                        currentBittgebet = new Bittgebete();
                    } else if (currentBittgebet != null) {
                        if (currentTag.equalsIgnoreCase(ID)) {
                            currentBittgebet.setId(Integer.parseInt(parser.nextText()));     
                            // currentBittgebet.setId(parser.nextText());
                        } else if (currentTag.equalsIgnoreCase(NAME)) {
                            currentBittgebet.setname(parser.nextText());
                        } else if (currentTag.equalsIgnoreCase(AR)) {
                            currentBittgebet.setar(parser.nextText());
                        } else if (currentTag.equalsIgnoreCase(DE)) {
                            currentBittgebet.setde(parser.nextText());
                        } else if (currentTag.equalsIgnoreCase(QUELLE)) {
                            currentBittgebet.setquelle(parser.nextText());
                        }
                    }
                    break;
                case XmlPullParser.END_TAG:
                    currentTag = parser.getName();
                    if (currentTag.equalsIgnoreCase(BITTGEBET) && currentBittgebet != null) {
                        bittgebeteList.add(currentBittgebet);
                    } else if (currentTag.equalsIgnoreCase(BITTGEBETE)) {
                        done = true;
                    }
                    break;
                }
                eventType = parser.next();
            }
 
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
 
        return bittgebeteList;
 
    }
 
}

ListViewAdapter.java

Code:

package de.jfd.xmlparsing;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Locale;

import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class ListViewAdapter extends BaseAdapter {

	// Declare Variables
	Context context;
	LayoutInflater inflater;
	ArrayList<HashMap<String, String>> data;
	private List<Bittgebete> bittgebete = null;
	private ArrayList<Bittgebete> arraylist;

	public ListViewAdapter(Context context,
			List<Bittgebete> bittgebete) {
		this.context = context;
		this.bittgebete = bittgebete;
		inflater = LayoutInflater.from(context);

		this.arraylist.addAll(bittgebete);
	}

	public class ViewHolder {

	}

	@Override

		return view;
	}

	// Filter Class
	public void filter(String charText) {

				if (wp.getname().toLowerCase(Locale.getDefault())
						.contains(charText)) {
					bittgebete.add(wp);
				}
			}
		}
		notifyDataSetChanged();
	}
}

MainActivity.java

Code:

package de.jfd.xmlparsing;

import java.util.List;

import android.app.ListActivity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.Menu;
 
//  GOAL: Build a native android Mobile Employee Directory 
 
//  ** The result is similar to the sample with Flex and Flash Builder 
//  see http://www.adobe.com/devnet/flex/articles/employee-directory-android-flex.html
 
//  PURPOSE: Learning how to build an Android App.
 
//  Step 2: Load data into the ListActivity from an XML file via XmlParser
//          1) employee_list.xml  (in res/xml)
//          2) Employee.java
//          3) EmployeeXmlParser.java
 
public class MainActivity extends ListActivity {
 
    public List<Bittgebete> bittgebete = null;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
 
        /*
         * This will work, but best practice is to place in a non-ui thread like below.
         *
         * EmployeeXmlParser parser = new EmployeeXmlParser();
         * bittgebete = parser.parse(this);
         *
         * ArrayAdapter<Employee> adapter = new ArrayAdapter<Employee>(this, android.R.layout.simple_list_item_1, bittgebete);
         * setListAdapter(adapter);
         */
 
        // Parse xml data in a non-ui thread
        new LoadbittgebeteTask().execute();
    }
 
    private class LoadbittgebeteTask extends AsyncTask<String, Void, List<Bittgebete>> {
 
        @Override
        protected List<Bittgebete> doInBackground(String... args) {
 
            // CALL XMLPULLPARSER & RETURN A LIST
            EmployeeXmlParser parser = new EmployeeXmlParser();
            bittgebete = parser.parse(getBaseContext());
 
            return bittgebete;
        }
 
        @Override
        protected void onPostExecute(List<Bittgebete> bittgebete) {
 
            //ArrayAdapter<Bittgebete> adapter = new ArrayAdapter<Bittgebete>(getBaseContext(), android.R.layout.simple_list_item_1, bittgebete);
 
        	ListViewAdapter adapter = new ListViewAdapter(MainActivity.this, bittgebete);
        	
            setListAdapter(adapter);
 
        }
 
    }
 
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
 
}

Wie man in der MainActivity sehen kann, habe ich den ArrayAdapter kommentiert nachdem es problemlos lief und wollte mit dem custom adapter versuchen, welches gescheitert ist.

Bittgebete.java

Code:

package de.jfd.xmlparsing;

public class Bittgebete {
    Integer _id;
    String _name;
    String _ar;
    String _de;
    String _quelle;
 
    // constructor
    public Bittgebete() {
 
    }
 
    // constructor with parameters
    public Bittgebete(Integer id, String name, String ar, String de, String quelle) {
        this._id = id;
        this._name = name;
        this._ar = ar;
        this._de = de;
        this._quelle = quelle;
    }
 
    // All set methods
 
    public void setId(Integer id) {
        this._id = id;
    }
 
    public void setname(String name) {
        this._name = name;
    }
 
    public void setar(String ar) {
        this._ar = ar;
    }
 
    public void setde(String de) {
        this._de = de;
    }
 
    public void setquelle(String quelle) {
        this._quelle = quelle;
    }
 
    // All get methods
 
    public Integer getId() {
        return this._id;
    }
 
    public String getname() {
        return this._name;
    }
 
    public String getar() {
        return this._ar;
    }
 
    public String getde() {
        return this._de;
    }
 
    public String getquelle() {
        return this._quelle;
    }
 
    //
    @Override
    public String toString() {
        return _name + " " + _ar + "\n" + _de;
    }
 
}

ICH WÜRDE MICH ÜBER JEGLICHE HILFE SEHR FREUEN

Danke schonmal im Vorraus
