java - How do I access variables within a Handler? Setting them public did not work -

-

i not know how use variables handler in different method. tried set variables(readbuf, readmessage, , msg) public, did not work. how access these variables in separate method? want variables listed including .arg1 , .obj in handler.

the code commented out processing data was. 

    public handler handler;     public byte[] readbuf;      public string readmessage;     public object msg;      handler = new handler();      private final handler mhandler = new handler() {         @override         public void handlemessage(message msg) {             switch (msg.what) {             case message_state_change:                 if(d) log.i(tag, "message_state_change: " + msg.arg1);                 switch (msg.arg1) {             case message_read:                        //for(int = 0; a< 8000; a++)                        //{                        try                         {                         byte[] readbuf = (byte[]) msg.obj;                         string readmessage = new string(readbuf,0,msg.arg1);                         mconversationarrayadapter.add("voltage: "+ readmessage);                         //double[] convert = new double[1];                         //for(int z=0; z <1;z++)                         //{                         //convert[z]= double.parsedouble(readmessage);                         //}                         //for(int j=0; j<1;j++)                         //{                         //stored[a][j]= convert[j];                         //}                         //}                         catch(numberformatexception e)                         {                          system.err.println("numberformatexception: "+e.getmessage());                         }                         //}                 break;             }         }     };      public void process()     {         new thread(new task()).start();     }      class task implements runnable     {         @override         public void run()          {                 try{                     thread.sleep(1000);                 }                 catch(interruptedexception e)                 {                     e.printstacktrace();                 }                 handler.post(new runnable()                 {                     @override                     public void run(){                         for(int = 0; a< 8000; a++)                         {                         byte[] readbuf = (byte[]) msg.obj;//error .obj                         try                         {                         string readmessage = new string(readbuf,0,msg.arg1);// error .arg1                         mconversationarrayadapter.add("voltage: "+ readmessage);                         double[] convert = new double[1];                         for(int z=0; z <1;z++)                         {                         convert[z]= double.parsedouble(readmessage);                         }                         for(int j=0; j<1;j++)                         {                         stored[a][j]= convert[j];                         }                         }                         catch(numberformatexception e)                         {                          system.err.println("numberformatexception: "+e.getmessage());                         }                         }                       }                 });         }      } }

the way used object variables in other methods setting new public static variables equal object variables. way use them in other methods.
