How to properly use load array and save array methods?

Question

I have the following code which is designed for the user to click on a button and when they click on the button, the particular string they are viewing is Favorited and stored s

Answer 1

loadArray function returns String[]. You might want to use it like:

String [] arr = loadArray("favorites");  

This array can be used later as you asked in 2nd part. Hope this helps.

Update [Based on your comment]

So, if you want to grab text in TextView and wish to add it in a List/String array:

1) Try to get the String from TextView

TextView display = (TextView)findViewById(R.id.display);
String toSave = display.getText().toString();

2) Get the existing list from SharedPreferences using `loadArray':

String [] arr = loadArray("favorites");  

3) Add the new String to it:

ArrayList arrList = new ArrayList();

for (int i=0; i

4) Save it Again.

saveArray(array, "favorites");
