How to use data from obtainMessage in Runnable?

Hello, i'm new at this, so i could use some help. How can i use data from "obtainMessage...sendToTarget" in Runnable? I know i would have to use handleMessage but i don't know how to implement it into Runnable.

Code:

---

    public void run() {
                byte[] buffer = new byte[256];  // buffer store for the stream
                int bytes; // bytes returned from read()

                // Keep listening to the InputStream until an exception occurs
                while (true) {
                        try {
                        // Read from the InputStream
                        bytes = mmInStream.read(buffer);                // Get number of bytes and message in "buffer"
                        h.obtainMessage(RECIEVE_MESSAGE, bytes, -1, buffer).sendToTarget();                // Send to message queue Handler
                    } catch (IOException e) {
                           
                        break;
                    }
                }
            }

Runnable:

Code:

---

    private final Runnable mLoop = new Runnable() {
         
          public void run() {
                 
                for(;;) {
            try {
                    //read data from "obtain message"
                //convert buffer into string
                    Thread.sleep(1000);
                    txt.post(new Runnable() {
                                       
                            public void run() {
                                                txt.setText("Data from PIC: " + //post string into textview );
                                        }
                                });
                   
            } catch (InterruptedException e) {

                e.printStackTrace();
            }
            }
        }
         
      };
