I would like to listen to three different events at the same time on an EditText

  1. Text changed events
  2. Touch events
  3. softKeyboard event

I am using a touch screen with a soft keyboard. Specifically, I would like to log these events to a file for further processing. The problem is that I was not able to listen for all three events simultaneously. Also, I was not able to catch the softkeyboard events at all. When I searched I found that the code I am using for key events works only for hard keyboard but I would like to catch those events from a softkeyboard.

I read several answers in stack overflow but they didn't solve my problem such as

How to combine OnClickListener and OnTouchListener for an ImageButton

touchEvent while typing with soft keyboard android

Receiving onTouch and onClick events with Android

I have been trying to solve this problems for several days but I didn't succeed.I returned false on the touch listener to allow the other listeners to catch the event but that also did not solve the issue. Any help or guidance will be highly appreciated.

I had to create cutome keyboard to be able to handle touch and keypress at the same time while acquiring acceleration data simultaneously.

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment
     View view=inflater.inflate(R.layout.fragment_typing, container, false);

    df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

    senSensorManager = (SensorManager) getActivity().getSystemService(Context.SENSOR_SERVICE);
    senAccelerometer = senSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    senSensorManager.registerListener(this, senAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);

    initializeTheCSVfile();




    mKeyboard = new Keyboard(getActivity(), R.xml.keyboard);

    phrase= view.findViewById(R.id.typing_edittxt);

    okBtn=view.findViewById(R.id.okbtn);
    okBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            String formattedDate = df.format(c.getTime());
            int ld=Utilities.getLevenshteinDistance("earth quakes are predictable",phrase.getText().toString());
            String[] data = {formattedDate,"LevenshteinDistance=",ld+""};
            writeDataToXls(data);
            mListener.onFragmentInteraction(2,xlsfile);
        }
    });


    phrase.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {


            v.onTouchEvent(event);   // handle the event first

            //Hide the system keyboard when the user touch the edittext
            InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
            if (imm != null) {
                imm.hideSoftInputFromWindow(v.getWindowToken(), 0);  // hide the soft keyboard
            }
            showKeyboardWithAnimation();
            return true;
        }
    });

                    super.onKey( primaryCode,keyCodes);
       //aquire the pressed key code and displayed label
                    KeyPrimaryCode=primaryCode;
                    typedDisplayedLabel=Character.toLowerCase(displayedLabel);


                }
