Android Studio – How to get values from array in strings.xml in order of each day?

I want to get values ​​from an array every day, respectively, and set these values ​​to a textbox. I can get values ​​from array and set them in textbox but next day value stays same. does not set the next value in array? what can I do?

<string-array name="morning">
    <item>Good Morning. Message 1.</item>
    <item>Good Morning. Message 2.</item>
    <item>Good Morning. Message 3.</item>
</string-array>

mTestArray = getResources().getStringArray(R.array.morning);

preference_shared = this.getSharedPreferences("PREFERENCE", MODE_PRIVATE);
text_shared = this.getSharedPreferences("TEXT", MODE_PRIVATE);

Calendar c = Calendar.getInstance();
int timeOfDay = c.get(Calendar.DAY_OF_YEAR);

if (timeOfDay >= 0 && timeOfDay < 24) {
    if (preference_shared.getBoolean("isFirstRun", true)) {
        dailyGreetings.setText(mTestArray[(0) % (mTestArray.length)]);
        saveDate();
    }else {
        if (!Objects.equals(preference_shared.getString("Date", ""), dateFormat.format(date))) {
            int idx = new Random().nextInt(mTestArray.length);
            dailyGreetings.setText(mTestArray[idx]);
            text_shared.edit().putString("TEXT", dailyGreetings.getText().toString()).apply();
            saveDate();
        }

    It’s Easy just

    Resources res = getResources();
String[] mornings = res.getStringArray(R.array.morning);

//then use mornings  as you use array.

        // Solution
    SharedPreferences sharedPreferences = getSharedPreferences("my_preference", MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPreferences.edit();

    String currentDate = new SimpleDateFormat("dd-MMM-yyyy", Locale.getDefault()).format(System.currentTimeMillis());
    String[] msgArrays = getResources().getStringArray(R.array.morning);

    String savedDate = sharedPreferences.getString(DATE_KEY, "");
    int savedCounter = sharedPreferences.getInt(COUNTER_KEY, 0);


    // First time
    if (savedDate.isEmpty()) {
        editor.putInt(COUNTER_KEY, savedCounter);
        editor.putString(DATE_KEY, currentDate);
        editor.apply();
    } else if (!savedDate.equals(currentDate)) {
        // New date appears, update shared preference.
        savedCounter++;
        if (savedCounter < msgArrays.length) {
            editor.putInt(COUNTER_KEY, savedCounter);
            editor.putString(DATE_KEY, currentDate);
            editor.apply();
        }
    }
    binding.tvTitle.setText(msgArrays[savedCounter]);

    In this snipped of code, I’m updating shared preference by date and counter.

    Date: It will be saved for next date, and if these both are not matching, shared preference will gets update with counter.

    Counter: The position of your strings-arrays.

    Reset: I have add another check that if in case your counter reaches to the end of array, it will be reset to ‘0’.
