集成代码
1集成集成，用于分享演示，IDL实现与华为分享服务的过程。
在“java”目录同级目录中创建“idl”接口目录（可手动添加或通过DevEco Studio创建）：com/huawei/hwshare/third（固定路径），然后创建名为IHwShareCallbackidl和IHwShareService.idl的IDL。文件。
IHwShareCallback.idl :
interface com.huawei.hwshare.third.IHwShareCallback {
[oneway] void notifyState([in] int state);
}
IHwShareService.idl :
sequenceable ohos.interwork.utils.PacMapEx;
interface com.huawei.hwshare.third.IHwShareCallback;
interface com.huawei.hwshare.third.IHwShareService {
int startAuth([in] String appId, [in] IHwShareCallback callback);
int shareFaInfo([in] PacMapEx pacMapEx);
}
2.创建FaManager类，分享管理方与华为的连接通道和数据分享使用。

代码实现
xml代码绘制一个文本按钮，
<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
xmlns:ohos="http://schemas.huawei.com/res/ohos"
ohos:height="match_parent"
ohos:width="match_parent"
ohos:alignment="center"
ohos:orientation="vertical">
<Text
ohos:id="$+id:text_huaweiShare"
ohos:height="match_content"
ohos:width="match_content"
ohos:background_element="$graphic:background_ability_main"
ohos:layout_alignment="horizontal_center"
ohos:text="华为分享"
ohos:text_size="40vp"
/>
</DirectionalLayout>
java代码给按钮实现点击事件，需要注意的必选参数，代码变成
package com.harmony.alliance.myapplication.slice;
import com.harmony.alliance.myapplication.MainAbility;
import com.harmony.alliance.myapplication.ResourceTable;
import com.harmony.alliance.myapplication.ShareFaManager;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.Component;
import ohos.global.resource.Resource;
import ohos.interwork.utils.PacMapEx;
public class MainAbilitySlice extends AbilitySlice {
@Override
public void onStart(Intent intent) {
super.onStart(intent);
super.setUIContent(ResourceTable.Layout_ability_main);
findComponentById(ResourceTable.Id_text_huaweiShare).setClickedListener(new Component.ClickedListener() {
@Override
public void onClick(Component component) {
try {
PacMapEx pacMap = new PacMapEx();
//todo 必选参数 分享的服务的bundleName
pacMap.putObjectValue(ShareFaManager.HM_BUNDLE_NAME, getBundleName());
//todo 分享的服务的Ability类名，最大长度1024，必选参数。
pacMap.putObjectValue(ShareFaManager.HM_ABILITY_NAME, MainAbility.class.getName());
//todo 卡片展示的服务介绍信息，最大长度1024，必选参数。
pacMap.putObjectValue(ShareFaManager.SHARING_CONTENT_INFO, "卡片展示的服务介绍信息");
Resource resource = getResourceManager().getRawFileEntry("resources/base/media/icon.png").openRawFile();
int size = resource.available();
byte[] buffer = new byte[size];
resource.read(buffer);
resource.close();
//todo 卡片展示服务介绍图片，最大长度153600，必选参数。
pacMap.putObjectValue(ShareFaManager.SHARING_THUMB_DATA, buffer);
// 携带的额外信息，可传递到被拉起的服务界面 ，最大长度10240，非必选参数。
pacMap.putObjectValue(ShareFaManager.SHARING_EXTRA_INFO, "分享的参数");
//服务图标，如果不传递此参数，取分享方默认服务图标，最大长度32768，非必选参数。
pacMap.putObjectValue(ShareFaManager.HM_FA_ICON, buffer);
//卡片展示的服务名称，最大长度1024，非必选参数。如果不传递此参数，取分享方默认服务名称。
pacMap.putObjectValue(ShareFaManager.HM_FA_NAME, "FAShareDemo");
// todo 第一个参数为appid，在华为AGC创建原子化服务时自动生成。
ShareFaManager.getInstance(MainAbilitySlice.this).shareFaInfo("自己的项目的appid", pacMap);
}catch (Exception e){
e.printStackTrace();
}
}
});
}
@Override
public void onActive() {
super.onActive();
}
@Override
public void onForeground(Intent intent) {
super.onForeground(intent);
}
}
运行效果
