Display the Contacts in sorting order ContactsContract.Contacts of Content Resolver

问题

My intention is to display the contacts in sorting order using content resolver in android.

For that i am writing:

Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?", new String[] { id }, null);

It needs that the last parameter in query method should not be null for sorting the elements by Name. Which part of code I have to replace the null parameter to achieve sorting by name ? Or please help me querying in such a case...

Thanks in advance

To sort result according to name use Phone.DISPLAY_NAME constant with ASC as last parameter to query method. do it as:

  Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
                   null, 
                   ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?",
                   new String[] { id },
                   ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");

You can use Upper() to sort for both lower as well as upper case contact name.

ContentResolver cr = getContentResolver();

Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
        null, null,  "upper("+ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + ") ASC");

It would be better to use SORT_KEY_PRIMARY or SORT_KEY_ALTERNATIVE on API level 11 and later.

Cursor cursor = getContentResolver().query(
    ContactsContract.Contacts.CONTENT_URI,
    null, null, null,
    ContactsContract.Contacts.SORT_KEY_PRIMARY + " ASC");

回答4:

The ContentResolver.query() method takes many arguments but to sort the content provider records, you have to edit the last argument of this method.

It should be like this:

Cursor cursor=getContentProvider().query(.......,"DISPLAY_NAME ASC")

This will arrange the contacts in Ascending order of their name.

Note: This argument should be in a String datatype.
