Hi,
I tried to select an item from the list, but not getting somebody
please help. I struck here for a long time. Actually in this, i am
using Baseadapter. So How can i select. I tried with onItemClick, but
null pointer exception coming..
public class ListQuery extends ListActivity implements
OnItemClickListener {
SQLiteDatabase myDatabase = null;
int size = 20;
String[] iStuffarea = new String[size];
String[] iStuffage = new String[size];
String[] iStuffsex = new String[size];
String[] iStuffheight = new String[size];
String[] iStuffweight = new String[size];
String[] iStuffcity = new String[size];
String[] iStuffcountry = new String[size];
String[] uStuffarea = new String[size];
String[] uStuffage = new String[size];
String[] uStuffsex = new String[size];
String[] uStuffheight = new String[size];
String[] uStuffweight = new String[size];
String[] uStuffcity = new String[size];
String[] uStuffcountry = new String[size];
int count = 0;
ArrayList<String> results = new ArrayList<String>();
