26 | The easiest and quickest way to receive all contacts (with their default profiles) 27 | 28 | ```kotlin 29 | // MainActivity#onCreate 30 | val viewModel = ViewModelProviders.of(this).get(ContactViewModel::class.java) 31 | var contacts: LiveData> = viewModel.getContacts() 32 | ``` 33 | This will load the contacts in an asynchronous thread with the following projections 34 | * CONTACT_ID 35 | * DISPLAY_NAME_PRIMARY 36 | * PHOTO_URI 37 | * PHOTO_THUMBNAIL_URI 38 | 39 | To change the default projection, you can parametrize the ```getContent``` method with your own projection 40 | 41 | ```kotlin 42 | val myNewProjection: Array = arrayOf( 43 | ContactsContract.Contacts._ID, 44 | ContactsContract.Contacts.DISPLAY_NAME_PRIMARY, 45 | ContactsContract.Contacts.PHOTO_URI, 46 | ContactsContract.Contacts.PHOTO_THUMBNAIL_URI) 47 | var contacts: LiveData> = viewModel.getContacts(projection = myNewProjection) 48 | ``` 49 | 50 | ```getContacts()``` will return ```LiveData>``` so you can access the data when the data is loaded 51 | 52 | ```kotlin 53 | viewModel.contacts.observe(this, Observer { 54 | myListAdapter.submitList(it) 55 | }) 56 | ``` 57 | 58 | The Contact class contains a map which stores the profiles from the contact. The key is representing the MimeType and the value the column which stores the account data. 59 | 60 | Example 61 | 62 | ```kotlin 63 | val MAIL = Pair( 64 | ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE, 65 | ContactsContract.CommonDataKinds.Email.ADDRESS 66 | ) 67 | ``` 68 | 69 | This Library supports per default the following profile types 70 | * Number 71 | * Mail 72 | * WhatsApp 73 | * Telegram 74 | * Signal 75 | 76 | you can easily extend this list by adding your own profile map 77 | 78 | ```kotlin 79 | val myProfiles = mapOf(DefaultProfiles.NUMBER, 80 | DefaultProfiles.MAIL, 81 | Pair("vnd.android.cursor.item/vnd.org.telegram.messenger.android.profile", "data1")) 82 | 83 | viewModel.setProfilesToReceive(myProfiles) 84 | ``` 85 | If you want to check if the contact has WhatsApp 86 | 87 | ```kotlin 88 | //ContactAdapter#onBindViewHolder 89 | val contact = getItem(position) 90 | if (contact.hasWhatsApp()) { 91 | // do stuff 92 | } 93 | ... 94 | ``` 95 | to check your custom profile types 96 | 97 | ```kotlin 98 | if (contact.hasProfile("vnd.android.cursor.item/email_v2") { 99 | // do stuff 100 | } 101 | ... 102 | ``` 103 | 104 | #
