Accessing of the data is not proper?

I am using android 2.1 platform.The code I have will display the Name number and email ID of all the persons from the Emulator contact list,by using this code I will get the requirement as on above.I have some contacts in my emulator, I created two more contacts (say C and D). BUT the issues are
Issue 1. If I create a new contact having name and number not email, This contact will take the email ID from the contact just down to it.for eg: if I create a name C has no email ID but D has email ID, D is the contact already in the Emulator. C will take D's email ID.C and D have same email ID.
Issue 2. If again I create a new contact having name email but not number, This contact will take the number from the contact I previously created.for eg: if I create the name E has no number but it will take the number of the contact C. so C and E have the same number .
I am using this code
public class GetAllDatas extends Activity {
ListView lvItem;
private Button btnAdd;
String displayName="", emailAddress="", phoneNumber="";
ArrayList<String> contactlist=new ArrayList<String>();
ArrayAdapter<String> itemAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lvItem = (ListView)this.findViewById(R.id.lvitems);
btnAdd = (Button)this.findViewById(R.id.btnAddItem);
itemAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,contactlist);
lvItem.setAdapter(itemAdapter);
btnAdd.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
readContacts();
}
});
}
private void readContacts()
{
ContentResolver cr =getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (cursor.moveToNext())
{
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Cursor emails = cr.query(Email.CONTENT_URI,null,Email.CONTACT_ID + " = " + id, null, null);
while (emails.moveToNext())
{
emailAddress = emails.getString(emails.getColumnIndex(Email.DATA));
break;
}
emails.close();
if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{id}, null);
while (pCur.moveToNext())
{
phoneNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
break;
}
pCur.close();
}
// To display the Details
contactlist.add(displayName+", "+phoneNumber+", "+ emailAddress+"\n");
itemAdapter.notifyDataSetChanged();
}
Collections.sort(contactlist);
cursor.close();
}
}
How can I solve this problem ?

As i Understand your question..
Before add new item in reference variables just erase the previous one..
like,
emailAddress = "" ;
displayName = "" ;
phoneNumber = "" ;
in your while loop for fetching contact information and adding it to list..
private void readContacts()
{
ContentResolver cr =getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (cursor.moveToNext())
{
emailAddress = "" ;
displayName = "" ;
phoneNumber = "" ;
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Cursor emails = cr.query(Email.CONTENT_URI,null,Email.CONTACT_ID + " = " + id, null, null);
while (emails.moveToNext())
{
emailAddress = emails.getString(emails.getColumnIndex(Email.DATA));
break;
}
emails.close();
if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{id}, null);
while (pCur.moveToNext())
{
phoneNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
break;
}
pCur.close();
}
// To display the Details
contactlist.add(displayName+", "+phoneNumber+", "+ emailAddress+"\n");
}
Collections.sort(contactlist);
itemAdapter.notifyDataSetChanged();
cursor.close();
}

try this one ..........
public void readContacts(){
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
contactName=new String[cur.getCount()];
contactNumber=new String[cur.getCount()][];
contactEmail=new String[cur.getCount()][];
int i=0;
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contactName[i]=name;
Log.e("Contact Name",contactName[i]);
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
contactNumber[i]=new String[pCur.getCount()];
int j=0;
while (pCur.moveToNext()) {
String phone = pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactNumber[i][j]=phone;
Log.d("Contact number",contactNumber[i][j]);
j++;
}
pCur.close();
}
// get email and type
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
contactEmail[i]=new String[emailCur.getCount()];
int k=0;
while (emailCur.moveToNext()) {
String email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String emailType = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
contactEmail[i][k]=email;
Log.v("Contact email",contactEmail[i][k]);
k++;
}
emailCur.close();
}
} i++;
}

Exception while reading contact list

Hi guys i'm getting the following Exception while readying contact list.
04-13 13:51:15.210: E/AndroidRuntime(7343): java.lang.IllegalStateException: get field slot from row 0 col -1 failed
Here is my getContact function
public static ContactList getContactList(Context context){
ContactList contactList = new ContactList(RequestStatus.CONTACT_LIST);
Cursor people = context.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
String number = people.getString(numberFieldColumnIndex);
contactList.addContact(new Contact(contact,number));
}
people.close();
return contactList;
}
The exception is being thrown at following line.
String number = people.getString(numberFieldColumnIndex);
what could be wrong?

You can use the below method to get a list of contacts::
private ContactList getDetails(){
ContactList contactList = new ContactList(RequestStatus.CONTACT_LIST);
Uri uri = contactsContract.CommonDataKinds.Phone.CONTENT_URI;
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER };
Cursor names = getContentResolver().query(uri, projection, null, null, null);
int indexName = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexNumber = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
names.moveToFirst();
do {
String name = names.getString(indexName);
Log.e("Name new:", name);
String number = names.getString(indexNumber);
Log.e("Number new:","::"+number);
contactList.addContact(new Contact(name,number));
} while (names.moveToNext());
return contactList;
}

You need to move to first column before, to make sure that the cursor is on valid index:
if (people.moveToFirst()) {
do {
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
String number = people.getString(numberFieldColumnIndex);
contactList.addContact(new Contact(contact,number));
}while(people.moveToNext());
}

I can tell you about exception. This was just about I not rturning the row which your required. either you requesting for invalid column

use
public static void getContactNumbers(Context context) {
String contactNumber = null;
int contactNumberType = Phone.TYPE_MOBILE;
String nameOfContact = null;
if (ApplicationConstants.phoneContacts.size() <= 0) {
ContentResolver cr = context.getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur
.getColumnIndex(BaseColumns._ID));
nameOfContact = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer
.parseInt(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor phones = cr
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id },
null);
while (phones.moveToNext()) {
contactNumber = phones.getString(phones
.getColumnIndex(Phone.NUMBER));
contactNumberType = phones.getInt(phones
.getColumnIndex(Phone.TYPE));
Log.i(TAG, "...Contact Name ...." + nameOfContact
+ "...contact Number..." + contactNumber);
}
phones.close();
}
}
}// end of contact name cursor
cur.close();
}
}
thats what help for me when I was the same problem

If any one know this please help me.

You only need access to an android.content.Context object to access the ContentResolver and thus query ContentProviders. Activity extends Context, so that works. android.app.Service also extends Activity, so that works too. android.app.Application also extends Context, so that will work too.

Organization has its own MIME type, so you'll also need to query for that.. This should help:
public Organization getContactOrg(String id) {
Organization org = new Organization();
String where = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] whereParameters = new String[]{id,
ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE};
Cursor orgCur = this.cr.query(ContactsContract.Data.CONTENT_URI, null, where, whereParameters, null);
if (orgCur.moveToFirst()) {
String orgName = orgCur.getString(orgCur.getColumnIndex(ContactsContract.CommonDataKinds.Organization.DATA));
String title = orgCur.getString(orgCur.getColumnIndex(ContactsContract.CommonDataKinds.Organization.TITLE));
if (orgName.length() > 0) {
org.setOrganization(orgName);
org.setTitle(title);
}
}
orgCur.close();
return(org);
}
