Question

我正在尝试编写一个模拟键盘输入的应用程序。活动中有一个函数 initialize()。该函数用于初始化 UI。但是，该功能使活动崩溃。我想知道为什么会发生这种情况。`

private void initialize(){
        // initialize the UI;
        labelsInitialize();
        calculatePositionsAndLocations();
        drawKeyboard();

        // set the target directory name and file name
        directoryName = "Subject_" + subjectID + "_" +firstName + "_" + lastName;
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault());
        resultFileName = "Day_" + dayNum + "_Keyboard_" + keyboardNum + "_" + sdf.format(new Date()) + ".txt";

        // create an object of the File I/O wrapper class
        bufferedData = new ArrayList<>();

        // load the test phrases and display the first target phrase on the interface
        // loadTestCaseFile();
        TargetPhrase.setText(testPhrases.get(currentPhraseNum));
        TranscribedPhrase.setText("");

        // set the touch event listener on part of the layout;
        myKC = findViewById(R.id.keyboard_container);
        myKC.setOnTouchListener(new View.OnTouchListener(){
            @Override
            public boolean onTouch(View v, MotionEvent event)
            {
                if (event.getAction() == MotionEvent.ACTION_DOWN){
                    touchEventHandler(event.getX(), event.getY());
                }
                return true;
            }

为什么初始化函数会导致活动崩溃？
