I am getting data from database and putting it into a array.Array contain CODE (int) and DESCRIPTION (String).Code is in the gridview and i want that if someone clicks on a code then realted description should be shown in a new activity.i have used OnItemclicklistener but dont know how to get only String from the array to show it on a new activity. "i want that the code from arraylist should be printed on first screen and when clicked description ll be printed in new activity as textview"
private void show_data() {
final GridView gv = (GridView) findViewById(R.id.gridView);
// final ListView listview = (ListView) findViewById(R.id.listView1);
final Database_handler db = new Database_handler(this);
Cursor cur = db.fetchAllData();
final ArrayList<String> array_list = new ArrayList<String>();
if (cur.moveToFirst()) {
do {
array_list.add(cur.getString(0));
array_list.add(cur.getString(1));
} while (cur.moveToNext());
}
final StableArrayAdapter adapter = new StableArrayAdapter(this,
android.R.layout.simple_list_item_1, array_list);
// listview.setAdapter(adapter);
gv.setAdapter(adapter);
gv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
/*SOME CODE*/ }
This is Stablearrayadapter class
public class StableArrayAdapter extends ArrayAdapter<String> {
HashMap<String, Integer> mIdMap = new HashMap<String, Integer>();
public StableArrayAdapter(Context context, int textViewResourceId, List<String> objects) {
super(context, textViewResourceId, objects);
for (int i = 0; i < objects.size(); ++i) {
mIdMap.put(objects.get(i), i);
}
}

activty for description
public class desc_view extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); //To change body of overridden methods use File | Settings | File Templates.
setContentView(R.layout.desc_view);

tv.setText(array_list_recvd.get(intValue));
setContentView(tv);
} catch (Exception e) {
Log.d("Error Second :", e.toString());
