TimePicker getCurrentHour() and getCurrentMinute() not working in Android-Collection of common programming errors

I’ve followed this tutorial http://developer.android.com/resources/tutorials/views/hello-timepicker.html to create a time picker, I then created a second one and I’m attempting to compare the difference between the two. I have the following method and for some reason getCurrentHour() and getCurrentMinute() are not working even though they have been imported as public methods. Here is my method:

private void calcShiftLength() {
int difHour = mTimeDisplayEnd.getCurrentHour() -mTimeDisplay.getCurrentHour();
int difMin = mTimeDisplayEnd.getCurrentMinute() - mTimeDisplay.getCurrentMinute();

mShiftLength.setText(new StringBuilder().append(difHour).append(":").append(difMin));
}

I get the following error code “The method getCurrentHour() is undefined for the type TextView” Thanks for any help. Edit:I realised some of the method was set up for testing the error, which I understand the issue I’m just unsure how to resolve it. Here is an exmaple of my TimePicker’s being used:

private TimePickerDialog.OnTimeSetListener mTimeSetListener = new     TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        mHour = hourOfDay;
        mMinute = minute;
        updateDisplay();
    }
};
private TimePickerDialog.OnTimeSetListener mTimeSetListenerEnd = new TimePickerDialog.OnTimeSetListener() {
    public void onTimeSet(TimePicker view2, int hourOfDay, int minute) {
        mHour = hourOfDay;
        mMinute = minute;
        updateDisplayEnd();
    }
};

Edit2: Here’s my declarations:

    private TextView mShiftLength;

private TextView mTimeDisplay;
private Button mPickTime;

private TextView mTimeDisplayEnd;
private Button mPickTimeEnd;

private int mHour;
private int mMinute;

static final int TIME_DIALOG_ID = 0;
static final int TIME_DIALOG_IDEND = TIME_DIALOG_ID + 1;

Edit 3: The following code is meant to convert the hours to an int and then take them away to calculate the difference. I will work with the 24 hour time later I just want to have it working for now. Anyway it is crashing my app at the moment:

    private void calcShiftLength() {
    int startTime = Integer.parseInt(mTimeDisplay.getText().toString());
    int endTime = Integer.parseInt(mTimeDisplayEnd.getText().toString());
    int shiftLength = endTime - startTime;

    mShiftLength.setText(new StringBuilder().append(shiftLength));
}

1. getCurrentHour() method can only be used with widget type TimePicker. Please confirm if your are using correct widget. The error clearly says you are trying access it using TextView instead.
