PS：也不知道为什么，自从加了融云之后在虚拟机里使用的时候一直会报俩错，估计应该是跟6.0的适配有关吧，不过真机不报错，并且也不影响使用，那就先这样放着吧
PPS：一开始账号打错了，我还真是老年人记忆力......囧
今天使用Bmob来实现好友关系的存储，融云的IM来实现好友间的聊天
先做好准备工作，融云的依赖添加好，首先是下最新的kit包，然后导入两个module，并且添加依赖
//融云IM依赖 compile project(':IMKit') 这里还有一些相关的设置，暂且不说，官网上有文档
这还不算完，因为这个程序里我们没有后台（竞赛提交作品要能直接演示，当然了，客观原因是我也不是很喜欢挂后台，挺麻烦的），所以我们得在客户端里实现后台的功能，所以我们需要导入一些融云的工具类
它们在哪下载呢，可以下载一个java的融云的后台demo，然后把其中的io.rong包复制过来，粘贴到项目里
这就算把先头工作做的差不多了，然后一步一步来
还是类似上一个活动模块的布局样式
activity_friend_info_fragm.xml
布局完了就是跟一个Activity
FriendInfoFragmActivity.java
public class FriendInfoFragmActivity extends Fragment { public static FriendInfoFragmActivity newInstance() { return new FriendInfoFragmActivity(); } @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.activity_friend_info_fragm, container, false); //Fragment+ViewPager+FragmentViewPager组合的使用 ViewPager viewPager = (ViewPager) view.findViewById(R.id.friendViewPaper); FriendPagerAdapter adapter = new FriendPagerAdapter(getActivity().getSupportFragmentManager(), getContext()); viewPager.setAdapter(adapter); //TabLayout TabLayout tabLayout = (TabLayout) view.findViewById(R.id.friendTabLayout); tabLayout.setupWithViewPager(viewPager); return view; }} 接着是建一个viewpager的adapter
FriendPagerAdapter.java
public class FriendPagerAdapter extends FragmentPagerAdapter { public final int COUNT = 2; private String[] titles = new String[]{"消息列表", "我的好友"}; private Context context; private Fragment conversationList; private Fragment conversationFragment = null; public FriendPagerAdapter(FragmentManager fm, Context context) { super(fm); this.context = context; } @Override public Fragment getItem(int position) { if(position==0){ conversationList = initConversationList();//获取融云会话列表的对象 return conversationList; }else if(position==1){ return FriendPageFragment.newInstance(); } return null; } @Override public int getCount() { return COUNT; } @Override public CharSequence getPageTitle(int position) { return titles[position]; } private Fragment initConversationList() { /** * appendQueryParameter对具体的会话列表做展示 */ if (conversationFragment == null) { ConversationListFragment listFragment = new ConversationListFragment(); Uri uri = Uri.parse("rong://" + context.getPackageName()).buildUpon() .appendPath("conversationList") .appendQueryParameter(Conversation.ConversationType.PRIVATE.getName(), "false")//设置私聊会话是否聚合显示 .appendQueryParameter(Conversation.ConversationType.GROUP.getName(), "true") // .appendQueryParameter(Conversation.ConversationType.PUBLIC_SERVICE.getName(), "false")//公共服务号 //.appendQueryParameter(Conversation.ConversationType.APP_PUBLIC_SERVICE.getName(), "false")//公共服务号 .appendQueryParameter(Conversation.ConversationType.DISCUSSION.getName(), "false")//设置私聊会话是否聚合显示 .appendQueryParameter(Conversation.ConversationType.SYSTEM.getName(), "false")//设置私聊会是否聚合显示 .build(); listFragment.setUri(uri); return listFragment; } else { return conversationFragment; } }} 左边是消息列表，这个用融云的消息列表，右边是好友列表，就需要我们自己定义了
从左至右吧
融云的消息列表
activity_conversation.xml
然后是Activity
（不是我说，这个命名是真的有毒，这个类是从融云提供的demo上摘下来的，不过反正是他们内部实现的东西，先不改得了，忙完这两天再一起弄）
public class ConversationActivity extends FragmentActivity { private TextView mName; //private ImageView mPersionInformationIv; private Conversation.ConversationType mConversationType; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_conversation); Intent intent = getIntent(); mConversationType = Conversation.ConversationType.valueOf(intent.getData().getLastPathSegment().toUpperCase(Locale.getDefault())); //Log.e("log", mConversationType.getName()); mName = (TextView) findViewById(R.id.name); /* mPersionInformationIv = (ImageView) findViewById(R.id.persionInformationIv); if(mConversationType.getName().equals("private")){ mPersionInformationIv.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent mIntent = new Intent(getApplicationContext(),UserInformationPage.class); Bundle bundle=new Bundle(); bundle.putString("userNickName", getIntent().getData().getQueryParameter("title")); mIntent.putExtras(bundle); startActivity(mIntent); } }); }else if(mConversationType.getName().equals("discussion")){ mPersionInformationIv.setVisibility(View.GONE); } */ String sId = getIntent().getData().getQueryParameter("targetId");//targetId:单聊即对方ID，群聊即群组ID String sName = getIntent().getData().getQueryParameter("title");//获取昵称 if (!TextUtils.isEmpty(sName)){ mName.setText(sName); }else {// sId //TODO 拿到id 去请求自己服务端 } }} 然后这个界面注册的方式不一样，这里也贴一下，其实官方文档有写
然后就是好友列表的实现
activity_friend_list.xml
item_friend_info.xml
左边直接new一个融云的会话列表就行，但是右边需要自己写
FriendPageFragment.java
public class FriendPageFragment extends Fragment implements RongIM.UserInfoProvider{ private SwipeRefreshLayout friendSwipeRefreshLayout; private FriendInfoListAdapter adapter; private List loginUserFriendInfoList; private List loginUserFriendRongList; private RecyclerView friendRecyclerView; private String loginUserFriendObjectID=""; private final int GETLOGINUSERFRIENDOBJECTID=0x00,GETLOGINUSERFRIENDLIST=0x01,FRIENDINFORMATIONLISTDOWNOVER=0x02; private Handler handler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); switch (msg.what){ case GETLOGINUSERFRIENDOBJECTID: getLoginUserFriendObjectID(); break; case GETLOGINUSERFRIENDLIST: getLoginUserFriendList(); break; case FRIENDINFORMATIONLISTDOWNOVER: loadFriendRecycleView(); initUserInfo(); friendSwipeRefreshLayout.setRefreshing(false); break; } } }; public static FriendPageFragment newInstance() { FriendPageFragment fragment = new FriendPageFragment(); return fragment; } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Nullable @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.activity_friend_list,container,false); friendSwipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_refresh_friend); friendSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { @Override public void onRefresh() { handler.sendEmptyMessage(GETLOGINUSERFRIENDLIST); } }); friendRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_friend); LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity()); friendRecyclerView.setLayoutManager(layoutManager); handler.sendEmptyMessage(GETLOGINUSERFRIENDOBJECTID); return view; } /** * 获取用户好友列表的数据库表单中ID */ private void getLoginUserFriendObjectID(){ final BmobQuery userObjectIDQuery = new BmobQuery (); userObjectIDQuery.addWhereEqualTo("userID", BmobUser.getCurrentUser(UserInfo.class).getUserPhone()); userObjectIDQuery.findObjects(new FindListener () { @Override public void done(List object, BmobException e) { if(e==null){ loginUserFriendObjectID =object.get(0).getObjectId(); //Toast.makeText(getContext(), "loginUserFriendObjectID"+loginUserFriendObjectID, Toast.LENGTH_SHORT).show(); handler.sendEmptyMessage(GETLOGINUSERFRIENDLIST); }else{ } } }); } /** *获取用户好友列表数据 */ private void getLoginUserFriendList(){ UserFriend userFriend = new UserFriend(); // 查询好友列表内的所有用户，因此查询的是用户表 BmobQuery userFriendQuery = new BmobQuery (); userFriend.setObjectId(loginUserFriendObjectID); //userFriend是UserFriend表中的字段，用来存储所有该用户的好友关系的用户 userFriendQuery.addWhereRelatedTo("userFriend", new BmobPointer(userFriend)); userFriendQuery.findObjects(new FindListener () { @Override public void done(List object,BmobException e) { if(e==null){ loginUserFriendInfoList=object; Log.e("taggg", loginUserFriendInfoList.size()+"" ); Log.e("taggg", loginUserFriendInfoList.get(0).getUserNickname()+"" ); //Toast.makeText(getContext(), "成功加载好友列表数据"+userFriendInformationList.size(), Toast.LENGTH_SHORT).show(); handler.sendEmptyMessage(FRIENDINFORMATIONLISTDOWNOVER); }else{ Toast.makeText(getContext(), "加载好友列表数据失败"+e, Toast.LENGTH_SHORT).show(); } } }); } /** * 加载好友信息至RecycleView */ private void loadFriendRecycleView(){ adapter = new FriendInfoListAdapter(getContext(),loginUserFriendInfoList,friendRecyclerView); adapter.setOnItemClickListener(new FriendInfoListAdapter.OnItemClickListener() { @Override public void onItemClick(View view, int position) { RongIM.getInstance().startPrivateChat(getContext(), loginUserFriendInfoList.get(position).getUserPhone(), loginUserFriendInfoList.get(position).getUserNickname()); } }); friendRecyclerView.setAdapter(adapter); } /** * 储存好友相关信息：id，昵称，token */ private void initUserInfo() { loginUserFriendRongList = new ArrayList (); loginUserFriendRongList.add(new Friend(BmobUser.getCurrentUser(UserInfo.class).getUserPhone(),BmobUser.getCurrentUser(UserInfo.class).getUserNickname(),BmobUser.getCurrentUser(UserInfo.class).getUserAvatar())); for(UserInfo userFriendInfo:loginUserFriendInfoList){ //好友内容为:id,昵称,头像url loginUserFriendRongList.add(new Friend(userFriendInfo.getUserPhone(),userFriendInfo.getUserNickname(),userFriendInfo.getUserAvatar())); } RongIM.setUserInfoProvider(this, true); } @Override public io.rong.imlib.model.UserInfo getUserInfo(String s) { for (Friend i : loginUserFriendRongList) { if (i.getUserId().equals(s)) { //Log.e(TAG, i.getPortraitUri()); return new io.rong.imlib.model.UserInfo(i.getUserId(), i.getName(), Uri.parse(i.getPortraitUri())); } } return null; }} 然后就需要写一个RecycleView的Adapter了
FriendInfoListAdapter.java
public class FriendInfoListAdapter extends RecyclerView.Adapter{ private List loginUserFriendInfoList; private Context context; private RecyclerView recyclerView; private OnItemClickListener onItemClickListener; static class ViewHolder extends RecyclerView.ViewHolder{ private ImageView userAvatarImg; private TextView userNameTv; public ViewHolder(View view){ super(view); userAvatarImg = (ImageView) view.findViewById(R.id.item_useravatar); userNameTv = (TextView) view.findViewById(R.id.item_username); } } public FriendInfoListAdapter(Context context,List loginUserFriendInfoList,RecyclerView recyclerView){ this.context = context; this.loginUserFriendInfoList = loginUserFriendInfoList; this.recyclerView = recyclerView; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_friend_info,parent,false); ViewHolder holder = new ViewHolder(view); return holder; } @Override public void onBindViewHolder(final FriendInfoListAdapter.ViewHolder holder, final int position) { holder.setIsRecyclable(false); final UserInfo friendInfo = loginUserFriendInfoList.get(position); Glide.with(context).load(friendInfo.getUserAvatar()).bitmapTransform(new CropCircleTransformation(context)).into(holder.userAvatarImg); holder.userNameTv.setText(friendInfo.getUserNickname()); if(onItemClickListener != null){ //为ItemView设置监听器 holder.itemView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { int position = holder.getLayoutPosition(); onItemClickListener.onItemClick(holder.itemView,position); } }); } } @Override public int getItemCount() { return loginUserFriendInfoList.size(); } /** * 点击事件接口 */ public interface OnItemClickListener{ void onItemClick(View view, int position); } /** * 设置点击事件方法 */ public void setOnItemClickListener(OnItemClickListener onItemClickListener){ this.onItemClickListener = onItemClickListener; }}
然后回头看一眼，首先在MainActivity里应该初始化融云的服务
RongIM.init(this); initUserToken();
/** * 获取融云所需userID及token */ private void initUserToken(){ UserInfo loginUser = BmobUser.getCurrentUser(UserInfo.class); userID = loginUser.getUserPhone(); connectRongServer(loginUser.getRongToken()); } /** * 初始化登录用户的融云服务 */ private void connectRongServer(String token) { RongIM.connect(token, new RongIMClient.ConnectCallback() { @Override public void onSuccess(String userId) { if (userId.equals(userID)){ Toast.makeText(getApplicationContext(), userID+"成功连接", Toast.LENGTH_SHORT).show(); }else { Toast.makeText(getApplicationContext(), userID+"连接失败", Toast.LENGTH_SHORT).show(); } } @Override public void onError(RongIMClient.ErrorCode errorCode) { // Log.e("onError", "onError userid:" + errorCode.getValue());//获取错误的错误码 Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_SHORT).show(); Log.e("MainActivity", "connect failure errorCode is : " + errorCode.getValue()); } @Override public void onTokenIncorrect() { Toast.makeText(getApplicationContext(), "TokenError", Toast.LENGTH_SHORT).show(); Log.e("MainActivity", "token is error ,please check token and appkey"); } }); } 实体类也需要完善一下了，我们现在还有很多其他需要的字段，以及融云所需的好友实体
UserInfo.java
public class UserInfo extends BmobUser { private String userNickname; private String userPhone; private String rongToken; //用户头像，先设置初始头像 private String userAvatar="http://bmob-cdn-8854.b0.upaiyun.com/2017/01/21/910615c0405f9bd280350b57f8dc180c.png"; public String getUserNickname() { return userNickname; } public void setUserNickname(String userNickname) { this.userNickname = userNickname; } public String getUserPhone() { return userPhone; } public void setUserPhone(String userPhone) { this.userPhone = userPhone; } public String getRongToken() { return rongToken; } public void setRongToken(String rongToken) { this.rongToken = rongToken; } public String getUserAvatar() { return userAvatar; } public void setUserAvatar(String userAvatar) { this.userAvatar = userAvatar; }} UserFriend.java
public class UserFriend extends BmobObject { private String userID; private BmobRelation userFriend; public BmobRelation getUserFriend() { return userFriend; } public void setUserFriend(BmobRelation userFriend) { this.userFriend = userFriend; } public String getUserID() { return userID; } public void setUserID(String userID) { this.userID = userID; }} Friend.java
public class Friend { private String userId; private String name; private String portraitUri; public String getUserId() { return userId; } public void setUserId(String userId) { this.userId = userId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPortraitUri() { return portraitUri; } public void setPortraitUri(String portraitUri) { this.portraitUri = portraitUri; } public Friend(String userId, String name, String portraitUri) { this.userId = userId; this.name = name; this.portraitUri = portraitUri; }} 行，然后把注册类完善一下
RegisterActivity.java
public class RegisterActivity extends BaseActivity implements View.OnClickListener{ private EditText usernameEt,passwordEt,userPhoneEt,userNicknameEt; private Button registerBtn,loginBtn; private UserInfo userInformation; private String rongToken="",userID=""; private final int ISREGISTER=0x00,GETRONGTOKEN=0x01,ALLSUCCESS=0x02,FAIL=0x03,BUILDUSERFRIENDLIST=0x04; private Handler handler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); switch (msg.what){ case ISREGISTER: isRegister(); break; case GETRONGTOKEN: new getRongToken(userPhoneEt.getText().toString().trim(),userNicknameEt.getText().toString().trim()).start(); break; case BUILDUSERFRIENDLIST: buildUserFriendList(); break; case ALLSUCCESS: register(); break; case FAIL: Toast.makeText(RegisterActivity.this,"获取Token失败 请检查网络和账号后重试", Toast.LENGTH_SHORT).show(); break; } } }; @Override protected void initVariablesAndService() { setIfImmersive(true); Bmob.initialize(this,"8da888d03200ff2f6b403d064b805d60"); } @Override protected void initViews(Bundle savedInstanceState) { setContentView(R.layout.activity_register); usernameEt = (EditText) findViewById(R.id.register_usernameEt); passwordEt = (EditText) findViewById(R.id.register_passwordEt); userPhoneEt = (EditText) findViewById(R.id.register_userPhoneEt); userNicknameEt = (EditText) findViewById(R.id.register_userNicknameEt); registerBtn = (Button) findViewById(R.id.register_registerBtn); registerBtn.setOnClickListener(this); loginBtn = (Button) findViewById(R.id.register_loginBtn); loginBtn.setOnClickListener(this); } @Override public void onClick(View v) { switch (v.getId()){ case R.id.register_registerBtn: userID = userPhoneEt.getText().toString().trim(); handler.sendEmptyMessage(ISREGISTER); break; case R.id.register_loginBtn: startActivity(LoginActivity.class); this.finish(); break; } } /** * 判断账号是否已被注册 */ private void isRegister(){ String username = usernameEt.getText().toString().trim(); BmobQuery query = new BmobQuery (); query.addWhereEqualTo("username",username); query.findObjects(new FindListener () { @Override public void done(List list, BmobException e) { if (e==null&&list.size()==0){ handler.sendEmptyMessage(GETRONGTOKEN); }else { Toast.makeText(RegisterActivity.this,"您的账号已被使用 请更换", Toast.LENGTH_SHORT).show(); } } }); } /** * 注册账号至bmob */ private void register(){ userInformation = new UserInfo(); userInformation.setUsername(usernameEt.getText().toString().trim()); userInformation.setPassword(passwordEt.getText().toString().trim()); userInformation.setUserPhone(userPhoneEt.getText().toString().trim()); userInformation.setUserNickname(userNicknameEt.getText().toString().trim()); userInformation.setRongToken(rongToken); userInformation.signUp(new SaveListener () { @Override public void done(UserInfo s, BmobException e) { if(e==null){ Toast.makeText(RegisterActivity.this,"注册成功", Toast.LENGTH_SHORT).show(); userInformation.login(new SaveListener () { @Override public void done(UserInfo userInfo, BmobException e) { if(e==null){ Toast.makeText(RegisterActivity.this,"登录成功", Toast.LENGTH_SHORT).show(); startActivity(MainActivity.class); RegisterActivity.this.finish(); } } }); }else{ Log.e("失败代码",e.toString()); } } }); } class getRongToken extends Thread{ String userId;//定义线程内变量 String name; User rongAppInformation = new User("cpj2xarlc68cn", "9gRSABvb08W3YC");//融云APP信息 String Token = ""; public getRongToken(String userId, String name){ //定义带参数的构造函数,达到初始化线程内变量的值 this.userId=userId; this.name=name; } @Override public void run() { try { //使用默认头像，但函数需要三参 Token=rongAppInformation.getToken(userId,name,"http://bmob-cdn-8854.b0.upaiyun.com/2017/01/21/910615c0405f9bd280350b57f8dc180c.png").getToken(); rongToken=Token ;//消息内容 handler.sendEmptyMessage(BUILDUSERFRIENDLIST); } catch (Exception e) { e.printStackTrace(); handler.sendEmptyMessage(FAIL); } } } /** * 如果用户此前没有生成好友列表的情况下，执行方法生成好友列表 */ private void buildUserFriendList(){ String loginUserID = userID; UserFriend userFriend = new UserFriend(); userFriend.setUserID(loginUserID); BmobRelation relation = new BmobRelation(); userFriend.setUserFriend(relation); userFriend.save(new SaveListener () { @Override public void done(String s, BmobException e) { if(e==null){ //Toast.makeText(getApplicationContext(), "执行", Toast.LENGTH_SHORT).show(); handler.sendEmptyMessage(ALLSUCCESS); }else{ //Toast.makeText(getApplicationContext(), e+"错误", Toast.LENGTH_SHORT).show(); } } }); }} 然后还是要加个添加好友的页面，样式大概就先做到和之前的那个添加活动差不多吧
