java - How to send data from one activity to another. (Bluetooth) -

-

i'm creating small bluetooth messenger app. have 2 activities main activity , messenger activity. main activity have background threads creating bluetooth socket , managing connection. when socket created starts messenger activity on both devices. messenger activity have edit box, list view , button. question how can send string has been taken edit box write() function in main activity.

    public void write(byte[] out) {     connectedthread cthread = new connectedthread(bluesocket);     cthread.write(out); }

when device gets message sends buffer handler.

buffer = new byte[1024];                 bytes = mminstream.read(buffer);                 // send obtained bytes ui activity                 mhandler.obtainmessage(message_read, bytes, -1, buffer)                         .sendtotarget();

handler takes string buffer. , here question: how send string messenger activity add list view.
