如何显示处理器/线程内敬酒？ [英] How to display a Toast inside a Handler/thread?

问题描述

我想显示敬酒，一旦消息被发送到一个socket.After这个 Log.d（ClientActivity，C：发送）;

I want to display a toast once the message is sent to a socket.After this "Log.d("ClientActivity", "C: Sent.");"

我是否需要创建一个单独的线程来显示吐司？

Whether I need to create a separate thread to display Toast?

public class ClientActivity extends Activity {
private Handler handler = new Handler();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.client);
    serverIp = (EditText) findViewById(R.id.EditText01);
    message =(EditText) findViewById(R.id.EditText02);
    connectPhones = (Button) findViewById(R.id.Button01);

}

    public void Click1(View v) {
        if (!connected) {
            serverIpAddress = serverIp.getText().toString();
            if (!serverIpAddress.equals("")) {
                Thread cThread = new Thread(new ClientThread());
                cThread.start();
            }
        }
    }


private class ClientThread implements Runnable {

    public void run() {
        try {
            InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
            Log.d("ClientActivity", "C: Connecting...");
            Socket socket = new Socket(serverAddr, ServerActivity.SERVERPORT);
            connected = true;
            while (connected) {
                try {
                    if(i>5)
                    {


                    } 
                    else
                    {   
                        Log.d("ClientActivity", "C: Sending command.");
                        PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket
                                .getOutputStream())), true);
                        // where you issue the commands
                        message1= message.getText().toString();
                        out.println(message1);
                        i=i+1;
                        Log.d("ClientActivity", "C: Sent.");
                    }    
                } catch (Exception e) {
                    Log.e("ClientActivity", "S: Error", e);
                }
            }
            socket.close();
            Log.d("ClientActivity", "C: Closed.");
        } catch (Exception e) {
            Log.e("ClientActivity", "C: Error", e);
            connected = false;
        }
    }
}

}

推荐答案

把

  runOnUiThread(new Runnable() {
                 public void run() {

                     Toast.makeText(ClientActivity.this,"asdf",Toast.LENGTH_LONG).show();
                }
            });

这行之后

  Log.d("ClientActivity", "C: Connecting...");
