Hi I am new to this android. I am just confused by base adapter. My problem is that consider In an array I have 10 items(from 0 to 9). In the getview() option of baseadapter I am displaying this in textview. But after executing 5 times correctly once again the position is resetting to 0. So items are repeating twice.
This is my adapterclass:
public class ListViewwithimageAdapter extends BaseAdapter
{
private static Context contxt;
final String URL = "http://xxxx.in/SSDAA.xml";
final String[] kickerimage = new String[150];
ListViewwithimageAdapter(Context conxt)
{
// System.out.println("inside cons");
this.contxt=conxt;
}
{
}
public String[] getelement()
{
// System.out.println("Insid getelement");
ArrayList<String> menuItems = new ArrayList<String>();
TaplistingParser parser = new TaplistingParser();
String xml= parser.getXmlFromUrl(URL);
Document doc=parser.getDomElement(xml);
// System.out.println("sssss="+doc);
NodeList nl=doc.getElementsByTagName("article");
final String[] url= new String[nl.getLength()];
// String headings = null;
for(int i=0; i < nl.getLength(); i++ )
{
// System.out.println("i="+i);
HashMap<String, String> map = new HashMap<String, String>();
Element e = (Element) nl.item(i);
// map.put("Title", parser.getValue(e, "title"));
// map.put("Date", parser.getValue(e, "create_date"));
url[i]=parser.getValue(e, "url");
// System.out.println("b4 kick");
// System.out.println("value="+parser.getValue(e, "title"));
kickerimage[i]=parser.getValue(e, "kickerimage");
// System.out.println("after kick");
// System.out.println("kick="+kickerimage[i]);
menuItems.add(parser.getValue(e, "title"));
}
// System.out.println("b4 items array");
String[] itemsarray = new String[menuItems.size()];
// System.out.println("subbu");
itemsarray=menuItems.toArray(itemsarray);
// System.out.println("subbu1");
// System.out.println("in last");
return itemsarray;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return getelement().length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return getelement()[position];
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
// System.out.println("pos in id="+position);
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
// TODO Auto-generated method stub
System.out.println("pos in id="+position); ------------------->This soutline gives output as(0,1,2,3,4,5,0).
Bitmap bitmap = DownloadImage(
kickerimage[position] );
LayoutInflater inflater = (LayoutInflater) contxt
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View listView;
if (convertView == null)
{
listView = new View(contxt);
listView = inflater.inflate(R.layout.homelistrow, null);
System.out.println("pos="+position);
System.out.println("item="+getItem(position));
TextView textView = (TextView) listView
.findViewById(R.id.name_label);
textView.setText(getelement()[position]);
ImageView imageView = (ImageView) listView
.findViewById(R.id.icon);
imageView.setImageBitmap(bitmap);
}
else
{
listView = (View) convertView;
}
return listView;
}
private Bitmap DownloadImage(String URL)
{
// System.out.println("image inside="+URL);
Bitmap bitmap = null;
InputStream in = null;
try {
in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in);
in.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// System.out.println("image last");
return bitmap;
}
private InputStream OpenHttpConnection(String urlString)
throws IOException
{
InputStream in = null;
int response = -1;
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
if (!(conn instanceof HttpURLConnection))
throw new IOException("Not an HTTP connection");
try{
HttpURLConnection httpConn = (HttpURLConnection) conn;
httpConn.setAllowUserInteraction(false);
httpConn.setInstanceFollowRedirects(true);
httpConn.setRequestMethod("GET");
httpConn.connect();
response = httpConn.getResponseCode();
if (response == HttpURLConnection.HTTP_OK) {
in = httpConn.getInputStream();
}
}
catch (Exception ex)
{
throw new IOException("Error connecting");
}
return in;
}
}
My Homerowlist:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="@+id/icon"
android:layout_width="80dp"
android:layout_height="80dp"
android:paddingLeft="10dp"
android:paddingRight="10dp" />
<TextView
android:id="@+id/name_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@+id/icon"
android:paddingBottom="10dp"
android:textColor="#ffffff"
android:textSize="16dp" />
</RelativeLayout>
In my activity setting adapter:
ListView l2= (ListView)findViewById(R.id.list);
ListViewwithimageAdapter adapter = new ListViewwithimageAdapter(this);
l2.setAdapter(adapter);
Please help me. Thanks in advance.
