How to access an object of other class inside another class in android

Question

How would I access the sqlitedatabase object which is passed to startindexing method, inside my thread class?

public void startindexing (SQLiteDatabase db) {
    new Thread() {
        public void run() {

            ContentValues values = new ContentValues();
            for (int i = 0; i < filelist.length-1; i++) {
                String cat = "O", ty;   
                values.put(NAME, filelist[i].getName());
                if (!filelist[i].isDirectory()) {
                                        ty = filelist[i].getName().substring(filelist[i].getName().lastIndexOf("."));
                    if (ty.equalsIgnoreCase(".mp3") || ty.equalsIgnoreCase(".wav") || ty.equalsIgnoreCase(".ogg") || ty.equalsIgnoreCase(".acc"))
                        cat = "A";
                    else if (ty.equalsIgnoreCase(".mp4") || ty.equalsIgnoreCase(".wmv") || ty.equalsIgnoreCase(".3gp") || ty.equalsIgnoreCase(".mkv") || ty.equalsIgnoreCase(".divx"))
                        cat = "V";
                    else if (ty.equalsIgnoreCase(".jpg") || ty.equalsIgnoreCase(".gif") || ty.equalsIgnoreCase(".png") || ty.equalsIgnoreCase(".bmp") || ty.equalsIgnoreCase(".webp"))
                        cat = "P";
                    else if (ty.equalsIgnoreCase(".txt"))
                        cat = "T";
                    values.put(TYPE,ty);
                } else { values.put(TYPE, "dir"); cat = "dir"; }
                values.put(CATEGORY, cat);
                values.put(PATH, filelist[i].getAbsolutePath());
                SQLiteDatabase db = ;
                db.insert(TABLE, null, values);
        }
    }
}.start();
}

That was crazy-hard to read. Consider at least some minor refactoring, too. — Dave Newton, Jun 13 '12 at 10:55
Could you please share your another class where you pass the SQLiteDatabase's object ? — Jitendra, Jun 13 '12 at 11:38

If you make the parameter final then you will be able to directly access it inside your thread's run() method. See How to pass parameters to anonymous class?

public void startindexing (final SQLiteDatabase db)

Remove this line:

SQLiteDatabase db=;

Make sure you aren't closing the DB connection somewhere else while your thread is running. – Graham Borland Jun 13 '12 at 12:48
