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 do a rtrim() to a Android Cursor query?

I have the following query:
Cursor c = sd.query(itemsTable.Table_Name, columns, itemsTable.ItemNumber + "= ?", selectionArgs, null, null, null);
I need to be able to do this:
'SQL Query I am running on the database using for testing
select * from items where rtrim(itemnumber) = '292664'
Where itemnumber is my selectionArgs.
The SQL query returns the correct results but the cursor query returns null.
I would rather not change the way I am running queries and would like to know if there is a way to convert my existing query to work the same as the SQL query.

Try the following:
String selection = "RTRIM(" + itemsTable.ItemNumber + ") = ?";
String[] selectionArgs = new String[] {"292664"}; // or whatever
Cursor c = sd.query(itemsTable.Table_Name, columns, selection, selectionArgs, null, null, null);

Get details of contact in single query

Hi all I am trying to get contact information from the contact database using ContentResolver with these field want to get name, number, FORMATTED_ADDRESS, PHOTO
details for a contact in one single query.
So basically I need to make 3 queries per contact to obtain these
details.
What I want to know is that, is there a simpler and more efficient way
to achieve what this.
but using the below code i am getting exception.
java.lang.IllegalArgumentException: Invalid column data1
Can any body help me for finding the solution for the same.
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS,
ContactsContract.CommonDataKinds.Photo.PHOTO};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor contacts = getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);

Maybe problem will be at selection. Replace yours method with mine.
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS,
ContactsContract.CommonDataKinds.Photo.PHOTO};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = ?";
String[] selectionArgs = { String.valueOf(1) };
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor contacts = getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);
You should always use parametrized statements. Your approach is dangerous. And your URI was bad.

Here you go
Replace
ContactsContract.Contacts.CONTENT_URI;
with
ContactsContract.CommonDataKinds.Phone.CONTENT_URI;

android ContactsContract query to show in listview

i am querying contacts through
private Cursor cursor;
private static final String SORT_ORDER = ContactsContract.Contacts.DISPLAY_NAME + " ASC ";
String[] myProjection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
ContactsContract.Contacts.STARRED};
cursor = managedQuery(ContactsContract.Contacts.CONTENT_URI, myProjection, null, null, SORT_ORDER);
and its giving me all contacts details.But my issue is its showing contacts with no entries as well.I want to query and show only those contacts which have at least an email or phone number .If contacts have no phone or email attached to it i dont want to show in my list view. What selection parameters should i need to give to filter them in my query.
Thanks

After query for your requirement use something like this:
if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
//show in Listview
}
else
{
Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",new String[]{id}, null);
if(emailCur.moveToNext())
{
//show in Listview
}
}

How to perform an SQLite query within an Android application?

I am trying to use this query upon my Android database, but it does not return any data. Am I missing something?
SQLiteDatabase db = mDbHelper.getReadableDatabase();
String select = "Select _id, title, title_raw from search Where(title_raw like " + "'%Smith%'" +
")";
Cursor cursor = db.query(TABLE_NAME, FROM,
select, null, null, null, null);
startManagingCursor(cursor);
return cursor;

This will return you the required cursor
Cursor cursor = db.query(TABLE_NAME, new String[] {"_id", "title", "title_raw"},
"title_raw like " + "'%Smith%'", null, null, null, null);

Alternatively, db.rawQuery(sql, selectionArgs) exists.
Cursor c = db.rawQuery(select, null);

This will also work if the pattern you want to match is a variable.
dbh = new DbHelper(this);
SQLiteDatabase db = dbh.getWritableDatabase();
Cursor c = db.query(
"TableName",
new String[]{"ColumnName"},
"ColumnName LIKE ?",
new String[]{_data+"%"},
null,
null,
null
);
while(c.moveToNext()){
// your calculation goes here
}

I came here for a reminder of how to set up the query but the existing examples were hard to follow. Here is an example with more explanation.
SQLiteDatabase db = helper.getReadableDatabase();
String table = "table2";
String[] columns = {"column1", "column3"};
String selection = "column3 =?";
String[] selectionArgs = {"apple"};
String groupBy = null;
String having = null;
String orderBy = "column3 DESC";
String limit = "10";
Cursor cursor = db.query(table, columns, selection, selectionArgs, groupBy, having, orderBy, limit);
Parameters
table: the name of the table you want to query
columns: the column names that you want returned. Don't return data that you don't need.
selection: the row data that you want returned from the columns (This is the WHERE clause.)
selectionArgs: This is substituted for the ? in the selection String above.
groupBy and having: This groups duplicate data in a column with data having certain conditions. Any unneeded parameters can be set to null.
orderBy: sort the data
limit: limit the number of results to return

Try this, this works for my code
name is a String:
cursor = rdb.query(true, TABLE_PROFILE, new String[] { ID,
REMOTEID, FIRSTNAME, LASTNAME, EMAIL, GENDER, AGE, DOB,
ROLEID, NATIONALID, URL, IMAGEURL },
LASTNAME + " like ?", new String[]{ name+"%" }, null, null, null, null);
