Question

地狱所有......我正在努力使用这个简单的聊天应用...我正在练习.....我无法让聊天列表自动刷新...只有这样我才能看到我发送的最新消息是关闭应用程序并重新打开...

`

ListView listView;
ArrayAdapter<String>listloader;
TextView editmsg;
Button convosend;
private static Handler handler;

@Override
public void onCreate(Bundle savedInstanceState)
{

    Parse.enableLocalDatastore(this);

    Parse.initialize(this, "", "");


    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);



    final EditText editmsg=(EditText)findViewById(R.id.editmsg);

    final Button convosend=(Button)findViewById(R.id.convosend);

    final ListView listView=(ListView)findViewById(R.id.listView);

    getActionBar().setTitle("Cyber chat");

handler =new Handler();

convosend.setOnClickListener(new OnClickListener()
    {

    @Override
    public void onClick(View v)
    {



    //button send




        String  msg= editmsg.getText().toString();


        ParseObject users = new ParseObject("Users");
        users.put("name", "mckeny");
        users.put("age", "26");
        users.put("gender", msg);

        users.saveEventually();



}}); handler.postDelayed(new Runnable()
    {
        @Override
        public void run()

        {   

ParseQuery <ParseObject> q=ParseQuery.getQuery("Users");

    q.setLimit(30);

q.orderByDescending("createdAt");
q.whereEqualTo("name","mckeny");
    q.findInBackground(new FindCallback<ParseObject>()
    {
        @Override
    public void done(List<ParseObject>u,ParseException e)
    {
        ArrayList<String>list =new ArrayList<String>();

    for(ParseObject user:u)
        {
        list.add(user.getString("name"));
            list.add(user.getString("gender"));}
        listloader = new ArrayAdapter(MainActivity.this,R.layout.list,list);

        listloader.notifyDataSetChanged();
        listView.setAdapter(listloader);


    }

    });


    }},1000);

要立即查看最新消息而无需关闭然后再打开应用程序，则需要设置和使用消息侦听器。这是一个如何在ConnectyCube聊天中实现接收消息的示例：

IncomingMessagesManager incomingMessagesManager = chatService.getIncomingMessagesManager();

incomingMessagesManager.addDialogMessageListener(new ChatDialogMessageListener() {
    @Override
    public void processMessage(String dialogId, ConnectycubeChatMessage message, Integer senderId) {

    }

    @Override
    public void processError(String dialogId, ChatException exception, ConnectycubeChatMessage message, Integer senderId) {

    }
});

麻烦刷新聊天
