（推荐）也可以这样获取联系人信息Uri：Uri uri = ContactsContract.Contacts.CONTENT_URI;

2.查询与添加联系人的操作（单元测试用例）

public class ContactTest extends AndroidTestCase {private static final String TAG = "ContactTest";/** * 获取通讯录中所有联系人的简单信息 * @throws Throwable */public void testGetAllContact() throws Throwable{//获取联系人信息的UriUri uri = ContactsContract.Contacts.CONTENT_URI;//获取ContentResolverContentResolver contentResolver = this.getContext().getContentResolver();//查询数据，返回CursorCursor cursor = contentResolver.query(uri, null, null, null, null);while(cursor.moveToNext()){StringBuilder sb = new StringBuilder();//获取联系人的IDString contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); //获取联系人的姓名String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); //构造联系人信息sb.append("contactId=").append(contactId).append(",Name=").append(name);//查询电话类型的数据操作Cursor phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); while(phones.moveToNext()){String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));//添加Phone的信息sb.append(",Phone=").append(phoneNumber);}phones.close();//查询Email类型的数据操作Cursor emails = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null); while (emails.moveToNext()) { String emailAddress = emails.getString(emails.getColumnIndex( ContactsContract.CommonDataKinds.Email.DATA)); //添加Email的信息 sb.append(",Email=").append(emailAddress); } emails.close();Log.i(TAG, sb.toString());}cursor.close();}/**添加联系人的第一种方法： * 首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获取系统返回的rawContactId * 这时后面插入data表的依据，只有执行空值插入，才能使插入的联系人在通讯录里面可见 */public void testInsert() {ContentValues values = new ContentValues();//首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获取系统返回的rawContactId Uri rawContactUri = this.getContext().getContentResolver().insert(RawContacts.CONTENT_URI, values);//获取idlong rawContactId = ContentUris.parseId(rawContactUri);//往data表入姓名数据values.clear();values.put(Data.RAW_CONTACT_ID, rawContactId); //添加idvalues.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);//添加内容类型（MIMETYPE）values.put(StructuredName.GIVEN_NAME, "凯风自南");//添加名字，添加到first name位置this.getContext().getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);//往data表入电话数据values.clear();values.put(Data.RAW_CONTACT_ID, rawContactId);values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);values.put(Phone.NUMBER, "13921009789");values.put(Phone.TYPE, Phone.TYPE_MOBILE);this.getContext().getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);//往data表入Email数据values.clear();values.put(Data.RAW_CONTACT_ID, rawContactId);values.put(Data.MIMETYPE, Email.CONTENT_ITEM_TYPE);values.put(Email.DATA, "kesenhoo@gmail.com");values.put(Email.TYPE, Email.TYPE_WORK);this.getContext().getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);}/**添加联系人的第二种方法： * 批量添加联系人 * @throws Throwable */public void testSave() throws Throwable{//官方文档位置：reference/android/provider/ContactsContract.RawContacts.html//建立一个ArrayList存放批量的参数ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();int rawContactInsertIndex = ops.size();ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI).withValue(RawContacts.ACCOUNT_TYPE, null).withValue(RawContacts.ACCOUNT_NAME, null).build());//官方文档位置：reference/android/provider/ContactsContract.Data.html//withValueBackReference后退引用前面联系人的idops.add(ContentProviderOperation.newInsert(android.provider.ContactsContract.Data.CONTENT_URI).withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex).withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE).withValue(StructuredName.GIVEN_NAME, "小明").build());ops.add(ContentProviderOperation.newInsert(android.provider.ContactsContract.Data.CONTENT_URI) .withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex) .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE) .withValue(Phone.NUMBER, "13671323809") .withValue(Phone.TYPE, Phone.TYPE_MOBILE) .withValue(Phone.LABEL, "手机号") .build());ops.add(ContentProviderOperation.newInsert(android.provider.ContactsContract.Data.CONTENT_URI) .withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex) .withValue(Data.MIMETYPE, Email.CONTENT_ITEM_TYPE) .withValue(Email.DATA, "kesen@gmail.com") .withValue(Email.TYPE, Email.TYPE_WORK) .build());ContentProviderResult[] results = this.getContext().getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);for(ContentProviderResult result : results){Log.i(TAG, result.uri.toString());}}}
