Create query for contacts

 Public classQuery {//ways to query contacts         Public StaticList<contact>Querycontact (Context context) {//Create a Collection objectList<contact> contacts=NewArraylist<contact>(); //Query the Raw_contact table first the table has several contact data//because contact data is exposed through the content provider, we can manipulate the database through content resolutionUri uri=uri.parse ("Content://com.android.contacts/raw_contacts"); Uri Datauri=uri.parse ("Content://com.android.contacts/data"); Cursor Cursor=context.getcontentresolver (). Query (URI,Newstring[]{"contact_id"},NULL,NULL,NULL);  while(Cursor.movetonext ()) {String contact_id=cursor.getstring (0); if(contact_id!=NULL) { Contact Contact=NewContact ();                    Contact.setid (contact_id); Cursor Cursor1=context.getcontentresolver (). Query (Datauri,Newstring[]{"Data1", "MimeType"}, "Raw_contact_id=?",NewSTRING[]{CONTACT_ID},NULL);  while(Cursor1.movetonext ()) {String data1=cursor1.getstring (0); String mimetype=cursor1.getstring (1); //Distinguishing Types                        if("Vnd.android.cursor.item/name". Equals (MimeType))                        {contact.setname (data1); }                        Else if("Vnd.android.cursor.item/phone_v2". Equals (MimeType))                        {Contact.setphone (data1); }                    }                    //put the contact into the collectionContacts.add (Contact); }            }            returncontacts; }}

Create a Contact wrapper class

 Public classContact {PrivateString ID; PrivateString name; PrivateString Phone;  PublicString getId () {returnID; }     Public voidsetId (String id) { This. ID =ID; }     PublicString GetName () {returnname; }     Public voidsetName (String name) { This. Name =name; }     PublicString Getphone () {returnphone; }     Public voidSetphone (String phone) { This. Phone =phone; }}
