新线程 handler

class CalculateThread extends Thread {
        private Handler handler;
        @Override
        public void run() {
            super.run();
            Looper.prepare();
            handler = new Handler() {
                @Override
                public void handleMessage(Message msg) {
                    super.handleMessage(msg);
                    if (msg.what == 0x1233) {
                        int upperNum = msg.getData().getInt("UPPER_NUM");
                        List<Integer> integers = calculateZ(upperNum);
                        Log.e("ouLog" , integers.toString());

                    }
                }
            };
            Looper.loop();
        }
    }

    //发送到handler
    EditText editText = (EditText)findViewById(R.id.upperNum);
            String upperNum = editText.getText().toString();
            Message msg = new Message();
            msg.what = 0x1233;
            Bundle bundle = new Bundle();
            bundle.putInt("UPPER_NUM", Integer.parseInt(upperNum));
            msg.setData(bundle);
            calculateThread.handler.sendMessage(msg);
