实训第三周（1）
本周完成了如下工作：
上一周未完成的NimUserHandler
(1)初始化
通过NimClient的getService接口获取到UserService(用户资料操作相关接口)服务实例，调用getUserInfo方法从本地数据库中获取用户资料
通过NimClient的getService接口获取到UserServiceObserve（用户资料变更通知）服务实例，调用observeUserInfoUpdate方法进行用户资料变更观察者通知
public void init(){
mUserInfo = NIMClient.getService(UserService.class).getUserInfo(mMyAccount);
mUpdateListeners = new ArrayList<>();
// 初始化监听
//用户资料托管接口，提供获取用户资料，修改个人资料等
NIMClient.getService(UserServiceObserve.class)
.observeUserInfoUpdate(new Observer>() {
@Override
public void onEvent(List userInfoList) {
NimUserInfo userInfo = userInfoList.get(0);
Log.e(TAG,"UserInfoUpdate"+userInfo.toString());
}
},true);
} （2）从服务器账户数据到本地数据库
通过NimClient的getService接口获取到UserService（用户资料操作相关接口）服务实例，调用fetchUserInfo从服务器获取用户资料
三种情况：同步成功，同步失败，同步出错
public void fetchAccountInfo(){
List accounts = new ArrayList<>();
accounts.add(mMyAccount);
NIMClient.getService(UserService.class).fetchUserInfo(accounts)
.setCallback(new RequestCallback>() {
@Override
public void onSuccess(List param) {
Log.e(TAG,"fetchAccountInfo onSuccess ");
mUserInfo = param.get(0);
// 同步成功，通知刷新
for (OnInfoUpdateListener listener : mUpdateListeners){
listener.myInfoUpdate();
}
}
@Override
public void onFailed(int code) {
Log.e(TAG,"fetchAccountInfo onFailed code " + code);
}
@Override
public void onException(Throwable exception) {
Log.e(TAG,"fetchAccountInfo onException message " + exception.getMessage());
}
});
} （3）将数据更新到服务器
将各项属性值（头像、生日、地址、签名、昵称、性别）存储到fields
再通过NimClient的getService接口获取到UserService（用户资料操作相关接口）服务实例，调用updateUserInfo更新本人用户资料
上传更新过程同样有三种情况：上传成功（更新本地数据库（调用fetchAccountInfo））,上传失败，上传出错
public void syncChange2Service(){
Map fields = new HashMap<>();
if(!TextUtils.isEmpty(mLocalAccount.getHeadImgUrl())){
fields.put(UserInfoFieldEnum.AVATAR,mLocalAccount.getHeadImgUrl());
}
if (!TextUtils.isEmpty(mLocalAccount.getBirthDay())){
fields.put(UserInfoFieldEnum.BIRTHDAY,mLocalAccount.getBirthDay());
}
if (!TextUtils.isEmpty(mLocalAccount.getLocation())){
fields.put(UserInfoFieldEnum.EXTEND,mLocalAccount.getLocation());
}
if (!TextUtils.isEmpty(mLocalAccount.getSignature())){
fields.put(UserInfoFieldEnum.SIGNATURE,mLocalAccount.getSignature());
}
fields.put(UserInfoFieldEnum.Name,mLocalAccount.getNick());
fields.put(UserInfoFieldEnum.GENDER,mLocalAccount.getGenderEnum().getValue());
NIMClient.getService(UserService.class).updateUserInfo(fields)
.setCallback(new RequestCallback() {
@Override
public void onSuccess(Void param) {
Log.e(TAG,"syncChange2Service onSuccess");
// 上传成功，更新本地数据库
fetchAccountInfo();
}
@Override
public void onFailed(int code) {
Log.e(TAG,"syncChange2Service onFailed code " + code);
//TODO 同步失败应当后台服务上传
}
@Override
public void onException(Throwable exception) {
Log.e(TAG,"syncChange2Service onException message " + exception.getMessage());
}
});
}
其中mLocalAccount为LocalAccountBean类，LocalAccountBean.java:
设置本地账户中的各项属性以及获取属性的方法
package com.ezreal.ezchat.bean;
import com.netease.nimlib.sdk.uinfo.constant.GenderEnum;
import java.io.Serializable;
/**
* Created by 张静.
*/
public class LocalAccountBean implements Serializable {
private String mHeadImgUrl;
private String mAccount;
private String mNick;
private GenderEnum mGenderEnum;
private String mBirthDay;
private String mLocation;
private String mSignature;
public String getHeadImgUrl() {
return mHeadImgUrl;
}
public void setHeadImgUrl(String headImgUrl) {
mHeadImgUrl = headImgUrl;
}
public String getAccount() {
return mAccount;
}
public void setAccount(String account) {
mAccount = account;
}
public String getNick() {
return mNick;
}
public void setNick(String nick) {
mNick = nick;
}
public GenderEnum getGenderEnum() {
return mGenderEnum;
}
public void setGenderEnum(GenderEnum genderEnum) {
mGenderEnum = genderEnum;
}
public String getBirthDay() {
return mBirthDay;
}
public void setBirthDay(String birthDay) {
mBirthDay = birthDay;
}
public String getLocation() {
return mLocation;
}
public void setLocation(String location) {
mLocation = location;
}
public String getSignature() {
return mSignature;
}
public void setSignature(String signature) {
mSignature = signature;
}
}public LocalAccountBean getLocalAccount() {
mLocalAccount = new LocalAccountBean();
mLocalAccount.setAccount(mUserInfo.getAccount());
mLocalAccount.setHeadImgUrl(mUserInfo.getAvatar());
mLocalAccount.setBirthDay(mUserInfo.getBirthday());
mLocalAccount.setNick(mUserInfo.getName());
mLocalAccount.setSignature(mUserInfo.getSignature());
mLocalAccount.setGenderEnum(mUserInfo.getGenderEnum());
String extension = mUserInfo.getExtension();
if (!TextUtils.isEmpty(extension)){
mLocalAccount.setLocation(extension);
}
return mLocalAccount;
}附上完整NimUserHandler.java
package com.ezreal.ezchat.handler;
