动态editext和textview加上slqlite更新语法

Question

嗨我有一个使用android studio的移动程序，我这里有一个edittext和一个动态创建的textview，edittext和textview的数量基于sqlite列数量和单位。并且我还要在确切的输出上添加一个版画屏幕，我想要的是当我滑动片段时，edittext中的值将保存在sqlite中并更新取决于 UNIT 这是动态创建的textview。我已经完成了刷卡和sqlite查询更新，我只是不知道如何保存edittext的逻辑取决于textview值，这是edittext和textview是dnamically创建和循环游标查询

//这里是使用游标创建动态textview和edittext的代码，它位于片段

中

public static class PageFragment extends Fragment {
        public static final String id = "id";
        public static final String cate = "category";
        public static final String code = "code";
        public static final String desk = "description";
        public static final String unit = "unit";
        public static final String quan = "Quantity";
        TextView tv;
        EditText et;
        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {

            View rootView = inflater.inflate(R.layout.fragment_item, container, false);


            ((TextView) rootView.findViewById(R.id.item_label2)).setText(
                    getArguments().getString(cate));
            ((TextView) rootView.findViewById(R.id.item_label3)).setText(

                    getArguments().getString(quan));
            ((TextView) rootView.findViewById(R.id.item_label1)).setText(
                    getArguments().getString(id));

            TextView code = (TextView)rootView.findViewById(R.id.item_label3);
            DBController controller = new DBController(getActivity());
            SQLiteDatabase db2 = controller.getWritableDatabase();

            Cursor mCursor2 = db2.rawQuery("SELECT Unit,Quantity FROM Countsheet WHERE TRIM(Code) = '"+ code.getText().toString() +"'", null);

            while (mCursor2.moveToNext()) {
                LinearLayout ll = (LinearLayout) rootView.findViewById(R.id.linearLayout2);
                // add text view
                            List<String> data = new ArrayList<String>();
                            data.add(mCursor2.getString(0));
                     for (int i = 0; i < data.size(); i++) {
                         tv = new TextView(getActivity());
                         tv.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 18);
                         tv.setTextColor(Color.BLACK);
                         tv.setText(data.get(i));
                         tv.setId(R.id.unit);
                         ll.addView(tv);

                         et = new EditText(getActivity());
                         et.setHint("Input Quantity");
                         et.setTextColor(Color.RED);
                         et.setId(R.id.quanity);
                         et.setText(mCursor2.getString(1));
                         et.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                         ll.addView(et);
                     }

//                mArrayList.add(mCursor2.getString(mCursor2.getColumnIndex(DBController.FeedReaderContract.FeedEntry.Col_5)));
//                Toast.makeText(getActivity(), "" + data, Toast.LENGTH_SHORT).show();
            }

            return rootView;

        }

//这是我更新查询中的代码

public void updateContact(data data) {

        SQLiteDatabase database = this.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put(FeedReaderContract.FeedEntry.Col_6, data.get_Quantity());
        // updating row
        database.update(TABLE_NAME, values, ""+FeedReaderContract.FeedEntry.Col_3 + "='" + data._Code+ "' AND "  +  FeedReaderContract.FeedEntry.Col_5 + "='" + data._Unit + "'", null);
        data.set_Code(data._Code);
        data.set_Unit(data._Unit);
        database.close();
    }

//这是我的代码，刷卡更新，这是另一个片段
