Я новичок в Android, и я пытаюсь передать строку из TextView из MainActivity в класс Client.java без активности. Я на самом деле пытаюсь сделать это в MainActivity :
Intent i = new Intent(MainActivity.this, Client.class);
i.putExtra("STRING_I_NEED", String.valueOf(indr));
В клиенте:
Context context;
Intent intent = ((Activity) context).getIntent();
static Bundle getIp = getIntent.getExtra("STRING_I_NEED");
public static final Bundle SERVERIP = getIp;
Но это говорит "
Не удается разрешить символ "getIntent" в строке
static Bundle getIp = getIntent.getExtra("STRING_I_NEED");
Код клиента:
public class Client {
private static String mIP= "";
private String serverMessage;
public static final String SERVERIP = mIP;
public static final int SERVERPORT = 4444;
private OnMessageReceived mMessageListener = null;
private boolean mRun = false;
PrintWriter out;
BufferedReader in;
public void setIp(String _IP) {
mIP = _IP;
}
public Client(OnMessageReceived listener) {
mMessageListener = listener;
}
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(String.valueOf(SERVERIP));
Log.e("TCP Client", "C: Connecting...");
Socket socket = new Socket(serverAddr, SERVERPORT);
try {
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
Log.e("TCP Client", "C: Sent.");
Log.e("TCP Client", "C: Done.");
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
while (mRun) {
serverMessage = in.readLine();
if (serverMessage != null && mMessageListener != null) {
mMessageListener.messageReceived(serverMessage);
}
serverMessage = null;
}
Log.e("RESPONSE FROM SERVER", "S: Received Message: '" + serverMessage + "'");
} catch (Exception e) {
Log.e("TCP", "S: Error", e);
} finally {
socket.close();
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
public interface OnMessageReceived {
void messageReceived(String message);
}
}
А вот и MainActivity:
public class MainActivity extends AppCompatActivity {
Server server;
Client client;
public static String message,ippi;
public static TextView terminale,indr,msg;
TextView log;
DataBaseHandler myDB;
allert Allert;
SharedPreferences prefs;
