Android: Retrieve Contact Name from Phone Number

Android: Retrieve contact name from phone number

For that you need to use the optimized PhoneLookup provider as described.

Add the permission to AndroidManifest.xml:

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

Then:

public String getContactName(final String phoneNumber, Context context)
{
    Uri uri=Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,Uri.encode(phoneNumber));

    String[] projection = new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME};

    String contactName="";
    Cursor cursor=context.getContentResolver().query(uri,projection,null,null,null);

    if (cursor != null) {
        if(cursor.moveToFirst()) {
            contactName=cursor.getString(0);
        }
        cursor.close();
    }

    return contactName;
}

Get contact name given a phone number in Android

Use reflections instead of comparing sdk version.

public String getContactName(final String phoneNumber) 
{  
    Uri uri;
    String[] projection;
    mBaseUri = Contacts.Phones.CONTENT_FILTER_URL;
    projection = new String[] { android.provider.Contacts.People.NAME }; 
    try {
        Class<?> c =Class.forName("android.provider.ContactsContract$PhoneLookup");
        mBaseUri = (Uri) c.getField("CONTENT_FILTER_URI").get(mBaseUri);
        projection = new String[] { "display_name" };
    } 
    catch (Exception e) {
    }

    uri = Uri.withAppendedPath(mBaseUri, Uri.encode(phoneNumber)); 
    Cursor cursor = this.getContentResolver().query(uri, projection, null, null, null); 

    String contactName = "";

    if (cursor.moveToFirst()) 
    { 
        contactName = cursor.getString(0);
    } 

    cursor.close();
    cursor = null;

    return contactName; 
}

Android: Get contact name using phone number

You didn't initialize the value context in your activity, and you are calling from activity so you can call like this,

contactName = getContactName(this, number);

or you can set the context value and call like this,

context = this;
contactName = getContactName(context, number);

Android. Retrieve first name and last name from contact book by phone number

PhoneLookup is a nice and quick way to get contact data by a phone number, but it returns a cursor limited to the columns mentioned in the docs.

You can see there's DISPLAY_NAME you can access, but not GIVEN_NAME, FAMILY_NAME.

GIVEN_NAME & FAMILY_NAME are fields stored in the Data table, which means you need to query that table separately to get to those fields.

So, you can just add another query using the contact ID you got from PhoneLookup (note that for each looked up phone there might be multiple contacts returned).

Here's a sample method to get first/last names from contact ID:

private void addNames(MyContact contact, long contactId) {
    String[] projection = new String[] {StructuredName.GIVEN_NAME, StructuredName.FAMILY_NAME};
    
    // filter to just StructuredName rows from the data table for the given contact
    String selection = Data.CONTACT_ID + "=" + contactID + " AND " + Data.MIMETYPE + "=" + StructuredName.CONTENT_ITEM_TYPE;
    
    Cursor cursor = getContentResolver().query(Data.CONTENT_URI, projection, selection, null, null);
    if (cursor.next()) {
        contact.setFirstName(cursor.getString(0));
        contact.setLastName(cursor.getString(1));
    }
    cursor.close();
}

Get phone number by contact name

Try this code out. You will need to set the permission in the manifest "android.permission.READ_CONTACTS" on true.

public String getPhoneNumber(String name, Context context) {
    String ret = null;
    String selection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" like'%" + name +"%'";
    String[] projection = new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER};
    Cursor c = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            projection, selection, null, null);
    if (c.moveToFirst()) {
        ret = c.getString(0);
    }
    c.close();
    if(ret==null)
        ret = "Unsaved";
    return ret;
    }

UPDATE:

This code snippet will allow you to read all messages from a particular contact:

StringBuilder smsBuilder = new StringBuilder();
       final String SMS_URI_INBOX = "content://sms/inbox"; 
        final String SMS_URI_ALL = "content://sms/";  
        try {  
            Uri uri = Uri.parse(SMS_URI_INBOX);  
            String[] projection = new String[] { "_id", "address", "person", "body", "date", "type" };  
            Cursor cur = getContentResolver().query(uri, projection, "address='123456789'", null, "date desc");
             if (cur.moveToFirst()) {  
                int index_Address = cur.getColumnIndex("address");  
                int index_Person = cur.getColumnIndex("person");  
                int index_Body = cur.getColumnIndex("body");  
                int index_Date = cur.getColumnIndex("date");  
                int index_Type = cur.getColumnIndex("type");         
                do {  
                    String strAddress = cur.getString(index_Address);  
                    int intPerson = cur.getInt(index_Person);  
                    String strbody = cur.getString(index_Body);  
                    long longDate = cur.getLong(index_Date);  
                    int int_Type = cur.getInt(index_Type);  

                    smsBuilder.append("[ ");  
                    smsBuilder.append(strAddress + ", ");  
                    smsBuilder.append(intPerson + ", ");  
                    smsBuilder.append(strbody + ", ");  
                    smsBuilder.append(longDate + ", ");  
                    smsBuilder.append(int_Type);  
                    smsBuilder.append(" ]\n\n");  
                } while (cur.moveToNext());  

                if (!cur.isClosed()) {  
                    cur.close();  
                    cur = null;  
                }  
            } else {  
                smsBuilder.append("no result!");  
            } // end if  
            }
        } catch (SQLiteException ex) {  
            Log.d("SQLiteException", ex.getMessage());  
        }
