Java 使用Sinch即时消息系统

我正在使用Sinch和Parse来集成到应用程序中的即时消息系统，我有两个问题

1） 由于某些原因，当显示消息传递活动时，我收到以下错误：消息客户端未启动”。此外，消息似乎没有在Sinch中通过，也没有在应用程序中直观地反映出来

下面是活动代码（当用户单击“快速聊天”按钮时，会将他们带到消息传递活动页面

下面是消息传递活动的活动代码

public class MessagingActivity extends Activity implements ServiceConnection, MessageClientListener {

    private String recipientId;
    private Button sendButton;
    private EditText messageBodyField;
    private String messageBody;
    private MessageService.MessageServiceInterface messageService;
    private MessageAdapter messageAdapter;
    private ListView messagesList;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.messaging);

        doBind();


        messagesList = (ListView) findViewById(R.id.listMessages);
        messageAdapter = new MessageAdapter(this);
        messagesList.setAdapter(messageAdapter);

        Intent intent = getIntent();
        recipientId = intent.getStringExtra("Name");

        messageBodyField = (EditText) findViewById(R.id.messageBodyField);
        sendButton = (Button) findViewById(R.id.sendButton);

        sendButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                sendMessage();
            }
        });
    }

    private void sendMessage() {
        messageBodyField = (EditText) findViewById(R.id.messageBodyField);
        messageBody = messageBodyField.getText().toString();
        if (messageBody.isEmpty()) {
            Toast.makeText(this, "Please enter a message", Toast.LENGTH_LONG).show();
            return;
        }

        //Here is where you will actually send the message throught Sinch
        messageService.sendMessage(recipientId, messageBody);
        messageBodyField.setText("");
    }

    private void doBind() {
        Intent serviceIntent = new Intent(this, MessageService.class);
        bindService(serviceIntent, this, BIND_AUTO_CREATE);
    }

    @Override
    public void onDestroy() {
        unbindService(this);
        super.onDestroy();
    }

    @Override
    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
        //Define the messaging service and add a listener
        messageService = (MessageService.MessageServiceInterface) iBinder;
        messageService.addMessageClientListener(this);
        if (!messageService.isSinchClientStarted()) {
            Toast.makeText(this, "The message client did not start."
                ,Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onServiceDisconnected(ComponentName componentName) {
        messageService = null;
    }

    @Override
    public void onMessageDelivered(MessageClient client, MessageDeliveryInfo deliveryInfo) {
        //Intentionally  left blank
    }

    @Override
    public void onMessageFailed(MessageClient client, Message message,
                                MessageFailureInfo failureInfo) {
        //Notify the user if message fails to send
        Toast.makeText(this, "Message failed to send.", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onIncomingMessage(MessageClient client, Message message) {
        messageAdapter.addMessage(message, MessageAdapter.DIRECTION_INCOMING);
    }

    @Override
    public void onMessageSent(MessageClient client, Message message, String recipientId) {
        messageAdapter.addMessage(message, MessageAdapter.DIRECTION_OUTGOING);
    }

    @Override
    public void onShouldSendPushData(MessageClient client, Message message, List<PushPair> pushPairs) {
        //Intentionally left blank
    }
}

2） 限制：我想设置一个限制，在特定的一方之间只有25条消息可用

提前谢谢，如果您需要任何澄清，请告诉我

更新3 当用户单击此按钮时，他将根据以下标准与他匹配的人进入MessagingActivity

        }

            // TODO Auto-generated method stub
              ParseQuery<ParseUser> query = ParseUser.getQuery();
                query.whereNotEqualTo("objectId", ParseUser.getCurrentUser()

                               startActivity(intent);
                           } else {

                                       Toast.LENGTH_SHORT).show();

我编写了您正在学习的教程，实际上昨天刚刚对其进行了更新，以解决您的第一个问题。请查看更新。在服务未启动时，新版本将显示一个进度对话框（加载微调器），直到服务启动或启动失败

---

你能澄清你的第二个问题吗？

只需在清单中声明你的服务。我遇到了同样的问题，它解决了它。

谢谢你的及时回复和更新。但是，在我的应用程序中，我没有ListUsersActivity，其中你有一个个人选择聊天的用户列表。相反，用户直接进入聊天室根据不同的标准与他匹配的人。为了礼貌起见，我已经包括了之前的活动（用户进入MessagingActivity之前的活动）在我第一篇文章的更新部分。至于第二个问题，它将每次对话之间的消息限制为25条。提前感谢。我已经按照您的建议添加了a进度对话框（加载微调器）到我的MattChopAction活动，并更新了我第一篇文章更新2部分下的代码。我现在的问题是，它无限期加载，并且似乎无法与客户端连接。很好！我意识到，重新安装应用程序时，进度对话框只会消失，因为该服务会在后台持续运行，并且不要在每次打开应用程序时就给客户端打电话。我会尽快更新教程。谢谢。我发现Sinch是最好的，也是我的首选，但我只是在体验如何让它工作。我认为建立各种标准也很有意思，例如设置可以发送的消息的限制在对话中，添加过滤功能，用户不能输入数字，只能输入字母等。同时，您建议的解决方案是什么？
