android - Send seekbar's values instead of text string -

i'm developing app based on bluetoothchat example have main activity 2 buttons:

1. find devices 2. configuration 

with first button search devices same code in mentioned example.

with second button, enter activity have 3 seekbars textviews under each 1 showing current seekbar's value.

what need modify bluetoothchat example's code send array 3 values instead of text.

this code of activity i'm trying develop this.

how can this?

 /*********************  *   * oncreate  *   ********************/  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.configuration);      bar1 = (seekbar)findviewbyid(r.id.fastbar);     bar1.setonseekbarchangelistener(this);     progress1 = (textview)findviewbyid(r.id.out1);      bar2 = (seekbar)findviewbyid(r.id.climbbar);     bar2.setonseekbarchangelistener(this);     progress2 = (textview)findviewbyid(r.id.out2);      bar3 = (seekbar)findviewbyid(r.id.platformbar);     bar3.setonseekbarchangelistener(this);     progress3 = (textview)findviewbyid(r.id.out3);      mpreferences = preferencemanager.getdefaultsharedpreferences(this);      /**initialize buffer outgoing messages*/     globalvar.moutstringbuffer = new stringbuffer(""); }     /*********************  *   * seekbar  *   ********************/  /**method each seekbar's value , save textview*/ @override public void onprogresschanged(seekbar bar, int progress, boolean fromuser) {     switch (bar.getid()) {         case r.id.fastbar:             progress1.settext(progress + "%");             break;         case r.id.climbbar:             progress2.settext(progress + "%");             break;         case r.id.platformbar:             progress3.settext(progress + "%");             break;     } }  @override public void onstarttrackingtouch(seekbar seekbar) { } @override public void onstoptrackingtouch(seekbar seekbar) {     seekbar.setsecondaryprogress(seekbar.getprogress()); }    /*********************  *   * onresume  *   ********************/  /**load seekbar's values sharedpreferences*/ @override protected void onresume() {     super.onresume();      loadedprogress1 = mpreferences.getint(key_progress_1, 50);     bar1.setprogress(loadedprogress1);     loadedprogress2 = mpreferences.getint(key_progress_2, 90);     bar2.setprogress(loadedprogress2);     loadedprogress3 = mpreferences.getint(key_progress_3, 70);     bar3.setprogress(loadedprogress3); }    /*********************  *   * onpause  *   ********************/  /**save seekbar's values on sharedfreferences*/ @override protected void onpause() {     super.onpause();      sharedpreferences.editor editor = mpreferences.edit();      savedprogress1 = bar1.getprogress();     editor.putint(key_progress_1, savedprogress1);     savedprogress2 = bar2.getprogress();     editor.putint(key_progress_2, savedprogress2);     savedprogress3 = bar3.getprogress();     editor.putint(key_progress_3, savedprogress3);     editor.commit(); }     /*********************  *   * options  *   ********************/  @override public boolean oncreateoptionsmenu(menu menu) {     /**inflate menu; adds items action bar if present.*/     getmenuinflater().inflate(r.menu.menu_conf, menu);     return true; }  /**options menu call send function*/ @override public boolean onoptionsitemselected(menuitem item) {     switch (item.getitemid()) {         case r.id.send:             sendvalues();             break;         case r.id.reset:             resetvalues(null);             break;     }     return true;  }     /*********************  *   * send & reset  *   ********************/  public void sendvalues() {      /**seekbars values*/     string message1 = progress1.gettext().tostring();     string message2 = progress2.gettext().tostring();     string message3 = progress3.gettext().tostring();      /**check we're connected before trying anything*/     if (globalvar.mtransmission.getstate() != globalvar.state_connected) {         toast.maketext(this, r.string.not_connected, toast.length_short).show();         return;     }      /**     *     *here i'm trying create function send 3 values in string type message     *this code setupchat() function, wrong in case             */      /**get message bytes , tell write*/     byte[] send = message.getbytes();     globalvar.mtransmission.write(send);      /**reset out string buffer zero*/     globalvar.moutstringbuffer.setlength(0); }   public void resetvalues() {      defaultvalue1 = 50;     bar1.setprogress(defaultvalue1);     defaultvalue2 = 90;     bar2.setprogress(defaultvalue1);     defaultvalue3 = 70;     bar3.setprogress(defaultvalue1);  } 

this new function created:

    public void sendvalues() {      /**send seekbars values*/     string message = progress1.gettext().tostring()+":"+progress2.gettext().tostring()+":"+progress3.gettext().tostring();     string[] values = message.split(":");     (string value : values) {          int number = integer.valueof(value);     }      /**check we're connected before trying anything*/     if (globalvar.mtransmission.getstate() != globalvar.state_connected) {         toast.maketext(this, r.string.not_connected, toast.length_short).show();         return;     }      /**get message bytes , tell transmission write*/     byte[] send = message.getbytes();     globalvar.mtransmission.write(send);      /**reset out string buffer zero*/     globalvar.moutstringbuffer.setlength(0); } 

you can send values string regularexpression ex. "5:15:33" , split when receive string on ":" this.

string str = bar1.gettext().tostring()+":"+bar2.gettext().tostring()+":"+bar3.gettext().tostring(); 

send str string reciver and, can int's out of string array

    string[] values = str.split(":");     (string value : values) {         int number = integer.valueof(value);     }
