How to Call Android Contacts List

How to call Android contacts list?

I'm not 100% sure what your sample code is supposed to do, but the following snippet should help you 'call the contacts list function, pick a contact, then return to [your] app with the contact's name'.

There are three steps to this process.

1. Permissions

Add a permission to read contacts data to your application manifest.

<uses-permission android:name="android.permission.READ_CONTACTS"/>

2. Calling the Contact Picker

Within your Activity, create an Intent that asks the system to find an Activity that can perform a PICK action from the items in the Contacts URI.

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

Call startActivityForResult, passing in this Intent (and a request code integer, PICK_CONTACT in this example). This will cause Android to launch an Activity that's registered to support ACTION_PICK on the People.CONTENT_URI, then return to this Activity when the selection is made (or canceled).

startActivityForResult(intent, PICK_CONTACT);

3. Listening for the Result

Also in your Activity, override the onActivityResult method to listen for the return from the 'select a contact' Activity you launched in step 2. You should check that the returned request code matches the value you're expecting, and that the result code is RESULT_OK.

You can get the URI of the selected contact by calling getData() on the data Intent parameter. To get the name of the selected contact you need to use that URI to create a new query and extract the name from the returned cursor.

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);

  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  getContentResolver().query(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          // TODO Whatever you want to do with the selected contact name.
        }
      }
      break;
  }
}

You can try LoaderManager

Create following fields

private static final int CONTACTS_LOADER_ID = 101;

private static final String[] PROJECTION = {
        ContactsContract.Contacts._ID,
        ContactsContract.Contacts.DISPLAY_NAME_PRIMARY,
        ContactsContract.CommonDataKinds.Phone.NUMBER
};

Create follwoing class

public class Contact {

    private String id;
    private String name;
    private String number;

    public Contact(String id, String name, String number) {
        this.id = id;
        this.name = name;
        this.number = number;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

}

[1] Create instance of LoaderManager.LoaderCallback

private LoaderManager.LoaderCallbacks<Cursor> loaderCallbacks = new LoaderManager.LoaderCallbacks<Cursor>() {
        @Override
        public Loader<Cursor> onCreateLoader(int id, Bundle args) {

            switch (id) {
                case CONTACTS_LOADER_ID:

                    return new CursorLoader(
                            getActivity(),
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            PROJECTION,
                            null,
                            null,
                            ContactsContract.Contacts.DISPLAY_NAME_PRIMARY + " ASC"
                    );
                default:
                    return null;
            }
        }

        @Override
        public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
            switch (loader.getId()) {
                case CONTACTS_LOADER_ID:

                   //Use ContactUtils class here


                    break;
            }
        }

        @Override
        public void onLoaderReset(Loader<Cursor> loader) {

        }
    };

[2] Use following class to convert cursor data to List<Contact>

import android.content.ContentResolver;
import android.database.Cursor;
import android.provider.ContactsContract;

import java.util.ArrayList;
import java.util.List;

public class ContactUtils {

    private ContactUtils() {
    }

    public static List<Contact> parseContacts(Cursor cursor) {
        List<Contact> contacts = new ArrayList<>();

        if (cursor.getCount() == 0) {
            return contacts;
        }

        int nameColumnIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME_PRIMARY);
        int idColumnIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID);
        int numberColumnIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

        while (cursor.moveToNext()) {
            String contactName = cursor.getString(nameColumnIndex);
            String id = cursor.getString(idColumnIndex);
            String number = cursor.getString(numberColumnIndex);

            Contact contact = new Contact(id, contactName, number);
            if(!isContactAddedInList(contact, contacts)){
                contacts.add(contact);
            }

        }

        return contacts;
    }

public boolean isContactAddedInList(Contact contact, List<Contact> contacts) {

    for (Contact listContact : contacts
            ) {
        if (listContact.number.equals(contact.name)) {
            return true;
        }
    }

    return false;
}


}

[3] Call getLoaderManager().initLoader method to load contacts in your Fragment or Activity's onStart method

getLoaderManager().initLoader(CONTACTS_LOADER_ID, null, loaderCallbacks);

Add <uses-permission android:name="android.permission.READ_CONTACTS" /> permission in menifest file
You need to ask for runtime permission before calling getLoaderManager().initLoader

How to get contact number from contactlist in Android?

I got this answer from the following link

http://tutorials-android.blogspot.in/2011/11/how-to-call-android-contacts-list.html

I need to call a particular number in the contacts

You just want to initiate the intent with ACTION_CALL like this.

First of all grab the phone number from the item from which the click happens.And use the code to initiate a call.

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+phonenumber));
startActivity(callIntent);

Hope you got the answer.

android get all contacts

Try this too,

private void getContactList() {
    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);

    if ((cur != null ? cur.getCount() : 0) > 0) {
        while (cur != null && cur.moveToNext()) {
            String id = cur.getString(
                    cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(
                    ContactsContract.Contacts.DISPLAY_NAME));

            if (cur.getInt(cur.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()) {
                    String phoneNo = pCur.getString(pCur.getColumnIndex(
                            ContactsContract.CommonDataKinds.Phone.NUMBER));
                    Log.i(TAG, "Name: " + name);
                    Log.i(TAG, "Phone Number: " + phoneNo);
                }
                pCur.close();
            }
        }
    }
    if(cur!=null){
        cur.close();
    }
}
