July 04, 2015
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
ContentProviderOperation
android.content.ContentProviderOperation is used to insert, update and delete contacts. In our example we will insert contacts. Find the some methods of ContentProviderOperation.newDelete(Uri uri): Creates builder to delete the contact.
newInsert(Uri uri): Creates builder to insert the contact.
newUpdate(Uri uri): Creates builder to update the contact.
ContentProviderOperation.Builder
A builder class which is instantiated by above methods ofContentProviderOperation. Find some methods which are commonly used.
withValue(String key, Object value) : Adds value to builder that will be inserted or updated. key is the name of value and value is value itself.
withValueBackReference(String key, int previousResult): Adds content values back refrence.
To insert a contact we write code as follows.
contentProviderOperations.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
.withValue(RawContacts.ACCOUNT_TYPE, null).withValue(RawContacts.ACCOUNT_NAME, null).build());
//insert contact display name using Data.CONTENT_URI
contentProviderOperations.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, 0).withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
.withValue(StructuredName.DISPLAY_NAME, displayName).build());
//insert mobile number using Data.CONTENT_URI
contentProviderOperations.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0).withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
.withValue(Phone.NUMBER, number).withValue(Phone.TYPE, Phone.TYPE_MOBILE).build());
getApplicationContext().getContentResolver(). applyBatch(ContactsContract.AUTHORITY, contentProviderOperations);
Code to Write Contacts
Here we are proving complete code to write contact. Using for loop we will write three contacts with display name and phone number.MainActivity.java
