啟動(dòng)DataAbility

啟動(dòng)DataAbility會(huì)獲取一個(gè)工具接口類對(duì)象（DataAbilityHelper）。啟動(dòng)DataAbility的示例代碼如下：

import featureAbility from '@ohos.ability.featureAbility';
import ability from '@ohos.ability.ability';

let uri: string = 'dataability:///com.samples.famodelabilitydevelop.DataAbility';
let DAHelper: ability.DataAbilityHelper = featureAbility.acquireDataAbilityHelper(uri);

訪問(wèn)DataAbility

訪問(wèn)DataAbility需導(dǎo)入基礎(chǔ)依賴包，以及獲取與DataAbility子模塊通信的URI字符串。

其中，基礎(chǔ)依賴包包括： 開(kāi)發(fā)前請(qǐng)熟悉鴻蒙開(kāi)發(fā)指導(dǎo)文檔 ：[gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md]

訪問(wèn)DataAbility的示例代碼如下：

創(chuàng)建工具接口類對(duì)象。

import featureAbility from '@ohos.ability.featureAbility';
import ohos_data_ability from '@ohos.data.dataAbility';
import ability from '@ohos.ability.ability';
// 作為參數(shù)傳遞的URI,與config中定義的URI的區(qū)別是多了一個(gè)"/",有三個(gè)"/"
let uri: string = 'dataability:///com.samples.famodelabilitydevelop.DataAbility';
let DAHelper: ability.DataAbilityHelper = featureAbility.acquireDataAbilityHelper(uri);

構(gòu)建數(shù)據(jù)庫(kù)相關(guān)的RDB數(shù)據(jù)。

import ohos_data_ability from '@ohos.data.dataAbility';
import rdb from '@ohos.data.rdb';
let valuesBucket_insert: rdb.ValuesBucket = { name: 'Rose', introduction: 'insert' };
let valuesBucket_update: rdb.ValuesBucket = { name: 'Rose', introduction: 'update' };

  { name: 'Rose', introduction: 'batchInsert_two' } as rdb.ValuesBucket);
let columnArray = new Array('id', 'name', 'introduction');
let predicates = new ohos_data_ability.DataAbilityPredicates();
