                cols, null, null, null); 
        for (int i = 0; i < cursor.getCount(); i++) { 
            cursor.moveToPosition(i); 
            // 取得联系人名字 
            int nameFieldColumnIndex = cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME); 
            int numberFieldColumnIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); 
            String name = cursor.getString(nameFieldColumnIndex); 
            String number = cursor.getString(numberFieldColumnIndex); 
            Toast.makeText(this, name + " " + number, Toast.LENGTH_SHORT).show();
