【通信录操作】

使用ContentResolver对通信录中的数据进行添加、删除、修改和查询操作：
加入读写联系人信息的权限
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />

加入读取联系人信息的权限
<uses-permission android:name="android.permission.READ_CONTACTS"/>

content://com.android.contacts/contacts 操作的数据是联系人信息Uri
content://com.android.contacts/data/phones 联系人电话Uri
content://com.android.contacts/data/emails 联系人Email Uri

读取联系人信息
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,  
    null, null, null, null);  
  while (cursor.moveToNext()) {  
   String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));  
   String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));  
   
   Cursor phones = getContentResolver().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));  
     Log.i("RongActivity", "phoneNumber="+phoneNumber);
    }  
    phones.close();  
   
    Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,  
       null,  
       ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,  
       null, null);  
       while (emails.moveToNext()) {  
        // This would allow you get several email addresses  
        String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
        Log.i("RongActivity", "emailAddress="+ emailAddress);
       }  
       emails.close();  
  }  
  cursor.close(); 

==================== 添加联系人 ===========================
方法一：
    /**
     * 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);
        long rawContactId = ContentUris.parseId(rawContactUri);
        //往data表入姓名数据
        values.clear();
        values.put(Data.RAW_CONTACT_ID, rawContactId); 
        values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);//内容类型
        values.put(StructuredName.GIVEN_NAME, "李天山");
        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, "liming@itcast.cn");
        values.put(Email.TYPE, Email.TYPE_WORK);
        this.getContext().getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);
    }

方法二：批量添加,处于同一个事务中
    public void testSave() throws Throwable{
        //文档位置：reference\android\provider\ContactsContract.RawContacts.html
        ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
        int rawContactInsertIndex = 0;
        ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
                .withValue(RawContacts.ACCOUNT_TYPE, null)
                .withValue(RawContacts.ACCOUNT_NAME, null)
                .build());
        //文档位置：reference\android\provider\ContactsContract.Data.html
        ops.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, "赵薇")
                .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, "liming@itcast.cn")
                 .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());
        }
    }
