Android基于云信实现单聊

一、添加依赖:

library-demonstrate  (由于上传文件限制)

二、添加包:

// 添加依赖。注意，版本号必须一致。
// 基础功能 (必需)
compile 'com.netease.nimlib:basesdk:4.4.0'
// 音视频和互动白板服务需要
compile 'com.netease.nimlib:nrtc:4.4.0'
// 音视频需要
compile 'com.netease.nimlib:avchat:4.4.0'
// 聊天室需要
compile 'com.netease.nimlib:chatroom:4.4.0'
// 互动白板服务需要
compile 'com.netease.nimlib:rts:4.4.0'
// 全文检索服务需要
compile 'com.netease.nimlib:lucene:4.4.0'
implementation 'com.jakewharton:butterknife:8.8.1'
//要添加此依赖否则事件无法响应
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

三、清单文件:

android:protectionLevel="signature" />

四、MyApp类:

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        // SDK初始化（启动后台服务，若已经存在用户登录信息， SDK 将完成自动登录）
        NIMClient.init(this, loginInfo(), options());
    }

    // 如果返回值为 null，则全部使用默认参数。
    private SDKOptions options() {
        SDKOptions options = new SDKOptions();

        // 如果将新消息通知提醒托管给 SDK 完成，需要添加以下配置。否则无需设置。
        StatusBarNotificationConfig config = new StatusBarNotificationConfig();
        config.notificationEntrance = WelcomeActivity.class; // 点击通知栏跳转到该Activity
        config.notificationSmallIconId = R.mipmap.ic_launcher_round;
        // 呼吸灯配置
        config.ledARGB = Color.GREEN;
        config.ledOnMs = 1000;
        config.ledOffMs = 1500;
        // 通知铃声的uri字符串
        config.notificationSound = "android.resource://com.netease.nim.demo/raw/msg";
        options.statusBarNotificationConfig = config;

        // 配置保存图片，文件，log 等数据的目录
        // 如果 options 中没有设置这个值，SDK 会使用下面代码示例中的位置作为 SDK 的数据目录。
        // 该目录目前包含 log, file, image, audio, video, thumb 这6个目录。
        // 如果第三方 APP 需要缓存清理功能， 清理这个目录下面个子目录的内容即可。
        String sdkPath = Environment.getExternalStorageDirectory() + "/" + getPackageName() + "/nim";
        options.sdkStorageRootPath = sdkPath;

        // 配置是否需要预下载附件缩略图，默认为 true
        options.preloadAttach = true;

        // 配置附件缩略图的尺寸大小。表示向服务器请求缩略图文件的大小
        // 该值一般应根据屏幕尺寸来确定， 默认值为 Screen.width / 2
        options.thumbnailSize = 480/2;

        // 用户资料提供者, 目前主要用于提供用户资料，用于新消息通知栏中显示消息来源的头像和昵称
        options.userInfoProvider = new UserInfoProvider() {
            @Override
            public UserInfo getUserInfo(String account) {
                return null;
            }

            @Override
            public String getDisplayNameForMessageNotifier(String account, String sessionId,
                                                           SessionTypeEnum sessionType) {
                return null;
            }

            @Override
            public Bitmap getAvatarForMessageNotifier(SessionTypeEnum sessionType, String sessionId) {
                return null;
            }
        };
        return options;
    }

    // 如果已经存在用户登录信息，返回LoginInfo，否则返回null即可
    private LoginInfo loginInfo() {
        return null;
    }
}

五、Activity类:

public class MainActivity extends AppCompatActivity {

    @BindView(R.id.tv_account)
    EditText tvAccount;
    @BindView(R.id.tv_pw)
    EditText tvPw;
    @BindView(R.id.btn_login)
    Button btnLogin;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);
    }

    @OnClick(R.id.btn_login)
    public void onViewClicked() {
        //封装登录信息.
        LoginInfo info
                = new LoginInfo(tvAccount.getText().toString(),tvPw.getText().toString());
        //请求服务器的回调
        RequestCallback callback =
                new RequestCallback() {
                    @Override
                    public void onSuccess(LoginInfo param) {
                        DemonstrateUtil
                                .showLogResult("onSuccess--"+param.getAccount()+"--"+param.getToken());
                        DemonstrateUtil.showToastResult(MainActivity.this,"登录成功!");

                        // 可以在此保存LoginInfo到本地，下次启动APP做自动登录用

                        //跳转到消息页面
                        startActivity(new Intent(MainActivity.this,WelcomeActivity.class));
                        finish();
                    }

                    @Override
                    public void onFailed(int code) {
                        DemonstrateUtil.showLogResult("登录失败!返回码"+code);
                    }

                    @Override
                    public void onException(Throwable exception) {
                        DemonstrateUtil.showLogResult(exception.toString());
                    }

                };
        //发送请求.
        NIMClient.getService(AuthService.class).login(info)
                .setCallback(callback);
    }
}

六、Welcome类:

public class WelcomeActivity extends AppCompatActivity {

    @BindView(R.id.tv_recivetv_in)
    TextView tvRecivetvIn;
    @BindView(R.id.tv_send_out)
    TextView tvSendOut;
    @BindView(R.id.et_input)
    EditText etInput;
    @BindView(R.id.btn_send)
    Button btnSend;
    @BindView(R.id.btn_out)
    Button btnOut;
    @BindView(R.id.btn_select_people)
    Button btnSelectPeople;
    private Observer> incomingMessageObserver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcom);
        ButterKnife.bind(this);

        //注册消息观察者,registerObserver
        registerObserver();
    }

    private void registerObserver() {
        // 处理新收到的消息，为了上传处理方便，SDK 保证参数 messages 全部来自同一个聊天对象。
        //消息接收观察者
        incomingMessageObserver = new Observer>() {
            @Override
            public void onEvent(List messages) {
                // 处理新收到的消息，为了上传处理方便，SDK 保证参数 messages 全部来自同一个聊天对象。
                IMMessage imMessage = messages.get(0);
                tvRecivetvIn.setText(imMessage.getFromNick() + "-->:" + imMessage.getContent());
                account = imMessage.getFromAccount();
            }
        };
        //注册消息接收观察者,
        //true,代表注册.false,代表注销
        NIMClient.getService(MsgServiceObserve.class)
                .observeReceiveMessage(incomingMessageObserver, true);
    }

    @OnClick({R.id.btn_send, R.id.btn_out, R.id.btn_select_people})
    public void onViewClicked(View view) {
        switch (view.getId()) {
            case R.id.btn_send:
                //发送消息
                sendMessage();
                break;
            case R.id.btn_out:
                //退出登录
                loginOut();
                break;
            case R.id.btn_select_people:
                //选择联系人.
                final String[] accounts = {"zxn001", "zxn002", "zxn003", "zxn004", "zxn011"};
                final String[] items = {
                        "吃饭",
                        "睡觉",
                        "敲码",
                        "爱表达",
                        "万万不能打游戏",
                };
                DialogUtil.showListDialog(WelcomeActivity.this, "请选择联系人!", items, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        account = accounts[which];
                        DemonstrateUtil.showToastResult(WelcomeActivity.this, items[which]);
                    }
                });
                break;
        }
    }

    private String account = "zxn002";

    private void sendMessage() {
        // 以单聊类型为例
        SessionTypeEnum sessionType = SessionTypeEnum.P2P;
        String text = etInput.getText().toString();
        // 创建一个文本消息
        IMMessage textMessage = MessageBuilder.createTextMessage(account, sessionType, text);

        // 发送给对方
        NIMClient.getService(MsgService.class).sendMessage(textMessage, false);
        tvSendOut.setText(text);
    }

    private void loginOut() {
        NIMClient.getService(AuthService.class).logout();
        finish();
        startActivity(new Intent(this, MainActivity.class));
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        //注销消息接收观察者.
        NIMClient.getService(MsgServiceObserve.class)
                .observeReceiveMessage(incomingMessageObserver, false);
    }
}
