How to search contacts by name and phone number?

I am using Contacts.CONTENT_FILTER_URI to search for contacts.
Uri contentUri = Uri.withAppendedPath(
ContactsContract.Contacts.CONTENT_FILTER_URI,
Uri.encode(searchString));
The searchstring can be either a number or a name. That works great.
My only problem is that the result does not contain a contact phone number.
I know that I can get it by querying ContactsContract.Data.CONTENT_URI. However, I would like to find a solution that will give me a contact name and phone number with a single query.

You should use Phone.CONTENT_FILTER_URI instead of Contacts.CONTENT_FILTER_URI
Docs say:
The filter is applied to display names as well as phone numbers.
Try this:
Uri filterUri = Uri.withAppendedPath(Phone.CONTENT_FILTER_URI, Uri.encode(searchString));
String[] projection = new String[]{ Phone.CONTACT_ID, Phone.DISPLAY_NAME, Phone.NUMBER };
Cursor cur = getContentResolver().query(filterUri, projection, null, null, null);

How to get the Contact Names of Array of ContactNumbers from Contacts in Android?

I have a requirement when I need to get the Contact name of the selected numbers from the ANDROID_CONTACTS.
I can get the name of a particular number using ->
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = cr.query(uri, new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
if (cursor == null) {
return;
}
How can I pass a list of numbers and get their respective names?

Here's the naive approach:
String[] phones = new String[] { "(212) 555-1111", "(212) 555-2222", "(212) 555-3333"};
String selection = Phone.NUMBER + "IN (?,?,?)";
String[] selectionArgs = phones;
String[] projection = new String[] { Phone.NUMBER, Phone.CONTACT_ID, Phone.DISPLAY_NAME };
Cursor cur = getContentResolver().query(Phone.CONTENT_URI, projection, selection, selectionArgs, null);
DatabaseUtils.dumpCursor(cur); // dumps the cursor to logcat
However, this will only work if you enter the phone number in exactly the same format as it is stored in the ContactsContract DB under NUMBER.
The nice thing about the PhoneLookup.CONTENT_FILTER_URI API you've used is that the format of the number doesn't matter, it'll find it in the DB in any format you use.
To replicate something like that, you can try using another field called NORMALIZED_NUMBER which should always hold the number in a specific format called E164.
So you can run a query like this:
String[] e164_phones = new String[] { "+12125551111", "+12125552222", "+12125553333"};
String selection = Phone.NUMBER + "IN (?,?,?)";
String[] selectionArgs = e164_phones; // all phones here must be in e164 format
String[] projection = new String[] { Phone.NUMBER, Phone.CONTACT_ID, Phone.DISPLAY_NAME };
Cursor cur = getContentResolver().query(Phone.CONTENT_URI, projection, selection, selectionArgs, null);
You'll probably need a way to convert a phone number to E164 format for this code, check out this answer then.

How to get contact id by phone number

I query the phone's calllog into a ListView. So when the user long clicks an item, a dialog comes up with options, including "View contact". To be able to view the contact the intent needs the contact id.
My problem is that I not always get to see the right contact. I click on Peter, and Peter's contact sheet comes up. I click on Sarah, and Jason's contact sheet comes up.
I must have been using this code the wrong way. Please help.
ContentResolver contentResolver = getContentResolver();
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phone));
Cursor cursor = contentResolver.query(uri, new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID}, null, null, null);
if(cursor!=null) {
while(cursor.moveToNext())
{
String contactName = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
contactid2 = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup._ID));
}
cursor.close();
}
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + contactid2));
startActivity(intent_contacts);
Maybe what I need is not the PhoneLookup._ID, but some other ID.
I also tried Felipe's answer here, same happens.
Edit:
on a HTC Desire HD (2.3.5) I get the proper contacts in 99% of the
cases.
on a ZTE Blade (2.2) I get the proper contacts in 60% of the cases.
on a Samsung Galaxy Ace (2.3.3) I get the proper contacts in 5% of the cases.
What the hell is going on???

After digging myself into theme, I found sven's help on googlegroups. The problem was that I was using a depracated intent. I read through many pages on the developer site, I must have missed it somehow.
I also post the full code.
contactid26 = null;
ContentResolver contentResolver = getContentResolver();
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phonenumintolist));
Cursor cursor =
contentResolver.query(
uri,
new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup._ID},
null,
null,
null);
if(cursor!=null) {
while(cursor.moveToNext()){
String contactName = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
contactid26 = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup._ID));
}
cursor.close();
}
if (contactid26 == null) {
Toast.makeText(DetailedCallHistory.this, "No contact found associated with this number", Toast.LENGTH_SHORT).show();
}
else {
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(contactid26)));
//Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + contactid26));
startActivity(intent_contacts);
}

Here in this case i am going to show you that how to get the ID, and
Name of any contact no, which you have enter and want to search, For
Example if you enter a no and want to search its Name and id then use
this code, it is working 100%, if you want further modification in
this, then you can tell me
Uri lookupUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,Uri.encode(phnno.getText().toString()));//phone no
String[] proj = new String[]
{///as we need only this colum from a table...
Contacts.DISPLAY_NAME,
Contacts._ID,
};
String id=null;
String sortOrder1 = StructuredPostal.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor crsr = getContentResolver().query(lookupUri,proj, null, null, sortOrder1);
while(crsr.moveToNext())
{
String name=crsr.getString(crsr.getColumnIndex(Contacts.DISPLAY_NAME));
id = crsr.getString(crsr.getColumnIndex(Contacts._ID));
Toast.makeText(this,"Name of this cntct is : " +name +"\n id is : "+id ,Toast.LENGTH_SHORT).show();
}
crsr.close();

How to display numbers from contact list?

I use the code below to display contact numbers, but it is displaying names and numbers from the contact list.
public void getContacts(Context context){
context.startActivity(new Intent(Intent.ACTION_PICK, People.CONTENT_URI));
}
Like the above code how can I use the below code for getting only contact numbers from the contact list? I need to display only contact numbers without showing names. Please help with the right solution to solve this problem.
Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, personId);
Uri phonesUri = Uri.withAppendedPath(personUri, People.Phones.CONTENT_DIRECTORY);
String[] proj = new String[] {Phones._ID, Phones.TYPE, Phones.NUMBER, Phones.LABEL}
Cursor cursor = contentResolver.query(phonesUri, proj, null, null, null);

Try and look at this site:
Query contacts.
There are multiple methods for retrieving different content from contacts.
Hopefully that could help.
