How can I create a list Array (the list display First Alphabet when scroll) with the cursor data?

+1  A: 

Go through every element in the Cursor, and add them one by one to the ArrayList.

ArrayList<WhateverTypeYouWant> mArrayList = new ArrayList<WhateverTypeYouWant>();
for(mCursor.moveToFirst(); mCursor.moveToNext(); mCursor.isAfterLast()) {
    // The Cursor is now set to the right position
    mArrayList.add(mCursor.getWhateverTypeYouWant(WHATEVER_COLUMN_INDEX_YOU_WANT));
}

(replace WhateverTypeYouWant with whatever type you want to make a ArrayList of, and WHATEVER_COLUMN_INDEX_YOU_WANT with the column index of the value you want to get from the cursor.)

Hi, The important thing I want to do is display "Fist character" in my List. After I get all data from cursor, I don't know how to convert it to an String[] Array to get "First character". It look something like this char firstLetter = mString[firstVisibleItem].charAt(0);
