java - Implementing Virtual Keyboard Android to PC -

i'm attempting use android phone keyboard pc. done on local wifi connection using sockets create client/server connection.

i'm using textwatcher pick change in characters in edittext , sending on server uses robot class write onto pc. using softkeyboard on android phone. issue when writing in edittext 1 character gets sent. , picked server.

e.g. type on android phone "a" , respective keypress simulated on server. if type character not read character if delete "a" , type character send character.

below client side of code, android application.

public class mainactivity extends appcompatactivity implements view.onkeylistener {   private final static int portnumber = ****; private final static string hostname = "192.168.0.8"; private final static string ctest = "connection test"; socket socket = null; private static string tag = "test";     @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      new thread() {         @override         public void run() {               try {                 log.i(ctest, "attempting connect");                 socket = new socket(hostname, portnumber);                 log.i(ctest, "connected");                  runonuithread(new runnable() {                     public void run() {                         toast.maketext(getbasecontext(), "connected successfully", toast.length_short).show();                     }                 });                  edittext edittext = (edittext)findviewbyid(r.id.edittext);                 edittext.addtextchangedlistener(edittextwatcher);             } catch (unknownhostexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             } catch (ioexception e) {                 // todo auto-generated catch block                 log.e(ctest, e.getmessage());             }         }      }.start(); }    private textwatcher edittextwatcher = new textwatcher() {    private void sendtexttoserver(string send) {        bufferedwriter bw = null;        string textchange = send;         try {           bw = new bufferedwriter(new outputstreamwriter(socket.getoutputstream()));           bw.write(textchange);           bw.newline();           bw.flush();        } catch (ioexception e) {        }   }      public void aftertextchanged(editable s)     {     }      public void beforetextchanged(charsequence s, int start, int count, int after)     {     }      public void ontextchanged(charsequence s, int start, int before, int count)     {             log.d(tag, s + " character read");                  string test = s.tostring();                 this.sendtexttoserver(test);     } };   @override public boolean onkey(view v, int keycode, keyevent event) {      return false;  } } 

the following code server side code being done in eclipse.

public class listenservermain {  private static boolean ifconnected = true; private final static int portnumber = ****; public static string readin; private static socket client = null; private static serversocket server = null; private static bufferedreader in = null; private static robot robot = null;   public static void main(string[] args) {     // todo auto-generated method stub          try {                 robot = new robot();                 server = new serversocket(portnumber);                   system.out.println("listening on port :****");                 client = server.accept(); //loops until client server connection established                 system.out.println("client connected");                  //receive message client                 bufferedreader in = new bufferedreader(                         new inputstreamreader(client.getinputstream()));                  while(ifconnected)                 {                          readin = in.readline();     //reads input received                          if(readin.equalsignorecase("a"))                                 {                                     robot.keypress(keyevent.vk_a);                                     robot.keyrelease(keyevent.vk_a);                                  }                         if(readin.equalsignorecase("b"))                                 {                                     robot.keypress(keyevent.vk_b);                                     robot.keyrelease(keyevent.vk_b);                                 }                         if(readin.equalsignorecase("c"))                                 {                                     robot.keypress(keyevent.vk_c);                                     robot.keyrelease(keyevent.vk_c);                                 }                         if(readin.equalsignorecase("bs"))                         {                             robot.keypress(keyevent.vk_delete);                             robot.keyrelease(keyevent.vk_delete);                         }                                 }                                                                system.out.println("unable read user input");            //if can't read input client                                 system.exit(-1);                                            //system exits                   system.out.println("server ended");                 system.exit(-1);              }                    catch (ioexception e) {                     system.out.println("can't open socket");                     system.exit(-1);                                         }                 catch (awtexception e) {                     system.out.println("unable create robot");                     system.exit(-1);                                         }          } } 

is there way in can read , send each character entered in edittext field?

if further clarification necessary let me know.

thanks
