This is my code that returns arraylist contains afield value:

public ArrayList<String> getAllPlayers() {

    SQLiteDatabase db = this.getReadableDatabase();
    Cursor cur = db.rawQuery("SELECT " + serailnumber + " as _id, " + title
            + " from " + table, new String[] {});
    ArrayList<String> array = new ArrayList<String>();
    while (cur.moveToNext()) {
        String uname = cur.getString(cur.getColumnIndex(title));
        array.add(uname);

    }
    return array;
}

You already did the hard part... the array stuff is pretty simple:

String[] array = new String[crs.getCount()];
int i = 0;
while(crs.moveToNext()){
    String uname = crs.getString(crs.getColumnIndex("NAME"));
    array[i] = uname;
    i++;
}

Whatever, I always recommend to use collections in cases like this:

List<String> array = new ArrayList<String>();
while(crs.moveToNext()){
    String uname = crs.getString(crs.getColumnIndex("NAME"));
    array.add(uname);
}

In order to compare the arrays, you can do things like this:

boolean same = true;
for(int i = 0; i < array.length; i++){
    if(!array[i].equals(ha[i])){
        same = false;
        break;
    }
}
// same will be false if the arrays do not have the same elements
