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;
}
}

Looking around for an API Level 5 solution using ContactsContract API you could slightly modify the code above with the following:
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
startActivityForResult(intent, PICK_CONTACT);
And then in onActivityResult use the column name:
ContactsContract.Contacts.DISPLAY_NAME
Here is the code snippet for get contact:
package com.contact;
import android.app.Activity;
import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class GetContactDemoActivity extends Activity implements OnClickListener {
private Button btn = null;
private TextView txt = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn = (Button) findViewById(R.id.button1);
txt = (TextView) findViewById(R.id.textView1);
btn.setOnClickListener(this);
}
@Override
public void onClick(View arg0) {
if (arg0 == btn) {
try {
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, 1);
} catch (Exception e) {
e.printStackTrace();
Log.e("Error in intent : ", e.toString());
}
}
}
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
try {
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
Cursor cur = managedQuery(contactData, null, null, null, null);
ContentResolver contect_resolver = getContentResolver();
if (cur.moveToFirst()) {
String id = cur.getString(cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String name = "";
String no = "";
Cursor phoneCur = contect_resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);
if (phoneCur.moveToFirst()) {
name = phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
no = phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
Log.e("Phone no & name :***: ", name + " : " + no);
txt.append(name + " : " + no + "\n");
id = null;
name = null;
no = null;
phoneCur = null;
}
contect_resolver = null;
cur = null;
// populateContacts();
}
} catch (IllegalArgumentException e) {
e.printStackTrace();
Log.e("IllegalArgumentException :: ", e.toString());
} catch (Exception e) {
e.printStackTrace();
Log.e("Error :: ", e.toString());
}
}
}
I do it this way for Android 2.2 Froyo release: basically use eclipse to create a class like: public class SomePickContactName extends Activity
then insert this code. Remember to add the private class variables and CONSTANTS referenced in my version of the code:
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intentContact, PICK_CONTACT);
}//onCreate
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode == PICK_CONTACT)
{
getContactInfo(intent);
// Your class variables now have the data, so do something with it.
}
}//onActivityResult
protected void getContactInfo(Intent intent)
{
Cursor cursor = managedQuery(intent.getData(), null, null, null, null);
while (cursor.moveToNext())
{
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if ( hasPhone.equalsIgnoreCase("1"))
hasPhone = "true";
else
hasPhone = "false" ;
if (Boolean.parseBoolean(hasPhone))
{
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
while (phones.moveToNext())
{
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
// Find Email Addresses
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);
while (emails.moveToNext())
{
emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emails.close();
Cursor address = getContentResolver().query(
ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + contactId,
null, null);
while (address.moveToNext())
{
// These are all private class variables, don't forget to create them.
poBox = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
street = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
city = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
state = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
postalCode = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
country = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));
type = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE));
} //address.moveToNext()
} //while (cursor.moveToNext())
cursor.close();
}//getContactInfo
