Answer 1

put below method in your database class:

public ArrayList getlist(String search) {

        ArrayList alTasklist = new ArrayList();

        try {
            Cursor mCursor = db.query(true, Contactsnew.TABLE02,
                    new String[] { your field list }, SearchColumnname + "='" + search
                            + "'", null, null, null, null, null);

            if (mCursor != null) {
                mCursor.moveToFirst();
                for (int i = 0; i < mCursor.getCount(); i++) {
                    alTasklist.add(mCursor.getString(0));
                    mCursor.moveToNext();
                }
                mCursor.close();
                return alTasklist;
            }
            return alTasklist;
        } catch (Exception e) {
            e.printStackTrace();
        }

        return alTasklist;
    }

Now get this method in your activity and then Initialize that return arraylist into ListView...
