本文介绍如何使用ContentResolver在Android应用中实现联系人的创建、读取、更新和删除（CRUD）操作。通过示例代码展示了如何插入新的联系人及其电话信息，并查询联系人的详细信息。

插入：

  ContentResolver cr =  getContentResolver();
        //向联系人中 插入一行数据
       ContentValues values = new ContentValues();
       Uri uri =  cr.insert(RawContacts.CONTENT_URI, values);
       Long raw_contact_id = ContentUris.parseId(uri);
       values.clear();
       //插入人名
       values.put(StructuredName.RAW_CONTACT_ID, raw_contact_id);
       values.put(StructuredName.DISPLAY_NAME, "张三三");
       values.put(StructuredName.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
       uri = cr.insert(Data.CONTENT_URI, values);
       //插入电话信息
       values.clear();
       values.put(Phone.RAW_CONTACT_ID,raw_contact_id);
       values.put(Phone.NUMBER,"13333333333");
       values.put(Phone.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
       uri = cr.insert(Data.CONTENT_URI, values);

查询：：



    ContentResolver cr = getContentResolver();
        Cursor c = cr.query(Contacts.CONTENT_URI, new String[] { Contacts._ID,
                Contacts.DISPLAY_NAME }, null, null, null);
        if (c != null) {
            while (c.moveToNext()) {
                int id = c.getInt(c.getColumnIndex("_id"));
                Log.i("info", "_id:" + id);
                Log.i("info",
                        "name:" + c.getString(c.getColumnIndex("display_name")));
                Cursor c1 = cr.query(Phone.CONTENT_URI, new String[] {
                        Phone.NUMBER, Phone.TYPE },
                        Phone.CONTACT_ID + "=" + id, null, null);
                // 根据联系人ID查询出联系人的电话号码
                if (c1 != null) {
                    while (c1.moveToNext()) {
                        int type = c1.getInt(c1.getColumnIndex(Phone.TYPE));
                        if (type == Phone.TYPE_HOME) {
                            Log.i("info",
                                    "家庭电话："
                                            + c1.getString(c1
                                                    .getColumnIndex(Phone.NUMBER)));
                        } else if (type == Phone.TYPE_MOBILE) {
                            Log.i("info",
                                    "手机："
                                            + c1.getString(c1
                                                    .getColumnIndex(Phone.NUMBER)));
                        }
                    }
                    c1.close();
                }
                // 根据联系人的ID去查询出联系人的邮箱地址
                Cursor c2 = cr.query(Email.CONTENT_URI, new String[] {
                        Email.DATA, Email.TYPE }, Email.CONTACT_ID + "=" + id,
                        null, null);
                if (c2 != null) {
                    while (c2.moveToNext()) {
                        int type = c2.getInt(c2.getColumnIndex(Email.DATA));
                        if (type == Email.TYPE_WORK) {
                            Log.i("info",
                                    "工作邮箱："
                                            + c2.getString(c2
                                                    .getColumnIndex(Email.DATA)));
                        }
                    }
                    c2.close();
                }
            }
            c.close();
        }
    }
