Accessing the Contact name, Number and Email ID?

Question

I am trying to access the contact name number and email ID using this code :

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;

public class GetAllDatas extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    readContacts();
}   

private void readContacts() {
    // TODO Auto-generated method stub

    ContentResolver cr = 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(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                System.out.println("name : " + name + ", ID : " + id);

                    // get the <span id="IL_AD1" class="IL_AD">phone number</span>


                Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
                                       ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
                                       new String[]{id}, null);
                while (pCur.moveToNext()) {
                      String phone = pCur.getString(
                             pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                      System.out.println("phone" + phone);
                }
                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);
                 while (emailCur.moveToNext()) {
                     // This would allow you get several email addresses
                         // if the email addresses were stored in an array
                     String email = emailCur.getString(
                                   emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                     String emailType = emailCur.getString(
                                   emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));

                   System.out.println("Email " + email + " Email Type : " + emailType);
                 }
                 emailCur.close();
            }
        }
    }

}
    }

When I run this code nothing would be displayed in my activity.

I need to access Contact name, number and email ID from my entire contact list on the activity window.

Where are you trying to display the contact information? The code above only reads from the database and there is no widget(like textview) used to display the received information. — Arun George, Jun 12 '12 at 08:57
Actually I need to display the retrieved information as a list, I am a beginner to Android, so please help me to do the display as a list — BigBoss, Jun 12 '12 at 09:13

Check with this

   package stack.examples;

import java.util.ArrayList;

public class StackOverFlowGetContactsActivity 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.listView_items);  
       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() {

               readContacts();

                contactlist.add("DisplayName: "+displayName+", PhoneNumber: "+phoneNumber+", EmailAddress: "+ emailAddress+"\n");
                itemAdapter.notifyDataSetChanged();
        }

now i am using your code...there are two errors like 1. Cursor.Close(); -- syntax error ,identifier expected after this token 2. public class Contact -- public type Contact must be defined in its own file any solutiion ? — BigBoss, Jun 12 '12 at 09:39
Thanks for editing ,the code have no error it's working but nothing will be displayed in main activity. Will I add any Widget to xml file ? — BigBoss, Jun 12 '12 at 10:02
you can disply this with listview or any Widget suitable for this — Ponmalar, Jun 12 '12 at 10:14
No man I was searching for the past 1 hour. I know how to use the list view by using the string [],on this we store the values,then by extending activity to ListActivity but it don't work in this problem we need a dynamic list view ? Do u know how to do ? — BigBoss, Jun 12 '12 at 11:57
Ponmalar Code is working properly got the desired output also.You did a great job to me thanks.thanks a lot. — BigBoss, Jun 13 '12 at 06:38
I got the correct answer but little more editing is required,if you are not free let me put the code in to a new question ? — BigBoss, Jun 13 '12 at 11:42
See the edited code, clear the values displayName="";emailAddress=""; phoneNumber=""; for every time before adding new. — Ponmalar, Jun 15 '12 at 10:08
