嗨，我对 android 很陌生，如果这是一个愚蠢的问题，我很抱歉。
如何使用 EditText 框而不是硬编码 IP 地址。正如您从下面的代码中看到的那样，我必须将我连接到的计算机 IP 地址放入其中，我想要做的是让它，所以我使用 EditText 框，例如：
String input= edittextIP.getText().toString();
但我无法让它工作。任何帮助将非常感激。
谢谢
public class Client {
private String serverMessage;
public final String SERVERIP = "100.100.100.61"; //computer IP address
public final int SERVERPORT = 4444;
private OnMessageReceived mMessageListener = null;
private boolean mRun = false;
PrintWriter out;
BufferedReader in;
/**
* Constructor of the class. OnMessagedReceived listens for the messages received from server
*/
public Client(OnMessageReceived listener) {
mMessageListener = listener;
}
/**
* Sends the message entered by client to the server
* @param message text entered by client
*/
public void sendMessage(String message){
if (out != null && !out.checkError()) {
out.println(message);
out.flush();
}
}
public void stopClient(){
mRun = false;
}
public void run() {
mRun = true;
try {
InetAddress serverAddr = InetAddress.getByName(SERVERIP);
Log.e("TCP Client", "C: Connecting...");
//create a socket to make the connection with the server
Socket socket = new Socket(serverAddr, SERVERPORT);
try {
//send the message to the server
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
Log.e("TCP Client", "C: Sent.");
Log.e("TCP Client", "C: Done.");
//receive the message which the server sends back
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
//in this while the client listens for the messages sent by the server
while (mRun) {
serverMessage = in.readLine();
if (serverMessage != null && mMessageListener != null) {
//call the method messageReceived from MyActivity class
mMessageListener.messageReceived(serverMessage);
}
serverMessage = null;
}
Log.e("RESPONSE FROM SERVER", "S: Received Message: '" + serverMessage + "'");
} catch (Exception e) {
Log.e("TCP", "S: Error", e);
} finally {
//the socket must be closed. I can't reconnect to this socket
// after it is closed, which means a new socket has to be created.
socket.close();
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
/// public EditText findViewByid(int edittextIP) { <--- this was previous try please
/// disregard this
///
/// return null;
/// }
public interface OnMessageReceived {
public void messageReceived(String message);
}
}
这是我下面的活动：
public class MyActivity extends Activity
{
private ListView mList;
private ArrayList<String> arrayList;
private Adapter mAdapter;
private Client mTcpClient;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
arrayList = new ArrayList<String>();
final EditText editText = (EditText) findViewById(R.id.editText);
Button send = (Button)findViewById(R.id.send_button);
mList = (ListView)findViewById(R.id.list);
mAdapter = new Adapter(this, arrayList);
mList.setAdapter(mAdapter);
// connect to the server
new connectTask().execute("");
send.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view) {
String message = editText.getText().toString();
arrayList.add("c: " + message);
//sends the message to the server
if (mTcpClient != null) {
mTcpClient.sendMessage(message);
}
//refresh the list
mAdapter.notifyDataSetChanged();
editText.setText("");
}
});
}
public class connectTask extends AsyncTask<String,String,Client> {
@Override
protected Client doInBackground(String... message) {
//create a TCPClient object and
mTcpClient = new Client(new Client.OnMessageReceived() {
//here the messageReceived is implemented
public void messageReceived(String message) {
publishProgress(message);
}
});
mTcpClient.run();
return null;
}
@Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
arrayList.add(values[0]);
mAdapter.notifyDataSetChanged();
}
}
}
