Edittext focus is automatically disabled after single rfid card scanned

Question

I have a app which is based on RFID reader and providing data is based on that tags. my layout view contains the edittext which has the Listener OnEditorActionListener to read rfid tags and Gridview to show the calendar (customised calendar).Listener and editText is everything working fine upto Jellybean 4.3. but am facing problem only in kitkat (4.4) .In KitKat i can read only single card after that the edittext focus is disabled automatically. I can't scan/read the second card .

Listener Code:

    editText_readRfid
            .setOnEditorActionListener(new OnEditorActionListener() {
                public boolean onEditorAction(TextView v, int actionId,
                        KeyEvent event) {
                    if (actionId == EditorInfo.IME_ACTION_SEARCH ||
                    actionId == EditorInfo.IME_ACTION_DONE ||
                    event.getAction() == KeyEvent.ACTION_DOWN &&
                    event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {
                        if (!event.isShiftPressed()) {
                            rfidData = editText_readRfid.getText()
                                    .toString();
                            editText_readRfid.getText().clear();                
                            if (mLinkedHashMap.containsKey(rfidData))
                            {
                                String timeStamp = (String) mLinkedHashMap
                                        .get(rfidData);
                                if (Util.checkTimeDifference(
                                        timeStamp,
                                        Util.getCurrentTimeStamp())) {

                                    mLinkedHashMap.put(rfidData,
                                        Util.getCurrentTimeStamp());
                                displayDetails(rfidData);

                                }

                                else {
                                    Util.showmessage(context, "Alert",
                                                    "You have already swiped the card");
                                }
                            }
                            else {

                                mLinkedHashMap.put(rfidData,
                                        Util.getCurrentTimeStamp());
                                displayStudentDetails(rfidData);
                            }
                            return true; // consume.
                        }
                    }
                    return false; // pass on to other listeners
                }

            });

after the focus disabled ,i tried this, inside edittext cursor blinking but no response

editText_readRfid.setOnFocusChangeListener(new OnFocusChangeListener() 
         {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus) {
                    Toast.makeText(context, "Focus :" + hasFocus,
                            Toast.LENGTH_LONG).show();
                    v.requestFocus();
                    v.setSelected(true);
                    v.setFocusable(true);

                }
            }
        });

Answer 1

After swiping the card am showing records and am updating gridview also so that focus went to Gridview.for that i disabled the Gridview cell(Button) focus and now its working fine.

gridcell.setFocusable(false);
