sqlite数据库异常导致应用程序崩溃

Question

我正在用数据库中的多个表创建一个android应用程序。因此，我有两个分别名为“供应商”和“客户”的按钮。我可以在“客户”活动上正确执行数据库操作，但是当我单击“供应商”按钮时，它崩溃了。这是error image。

我尝试交叉检查每行代码，并且也交叉检查以查看是否忘记了.xml与.java的链接。

VendorBaramatiDBHelper.java

 public List getAllVendorsBaramati() {
        List vendorsbaramatiDetailsList = new ArrayList();
        String selectQuery = "SELECT * FROM " + TABLE_NAME
                + " ORDER BY " + KEY_VENDORBARAMATI_ID + " DESC";
        SQLiteDatabase db = this.getReadableDatabase();
        Cursor cursor = db.rawQuery(selectQuery, null);

        //if TABLE has rows
        if (cursor.moveToFirst()) {
            //Loop through the table rows
            do {
                BaramatiVendorsDetails baramatiVendorsDetails = new BaramatiVendorsDetails();
                baramatiVendorsDetails.setVendorIdbaramati(cursor.getInt(0));
                baramatiVendorsDetails.setVendorNamebaramati(cursor.getString(1));
                baramatiVendorsDetails.setProductNameVendorbaramati(cursor.getString(2));
                baramatiVendorsDetails.setQuantityVendorbaramati(cursor.getInt(3));
                baramatiVendorsDetails.setRateVendorbaramati(cursor.getInt(4));
                baramatiVendorsDetails.setTotalpriceVendorbaramati(cursor.getInt(5));
                baramatiVendorsDetails.setPaidVendorbaramati(cursor.getInt(6));
                baramatiVendorsDetails.setUnpaidVendorbaramati(cursor.getInt(7));

                //Add movie details to list
                vendorsbaramatiDetailsList.add(baramatiVendorsDetails);
            } while (cursor.moveToNext());
        }
        db.close();
        return vendorsbaramatiDetailsList;
    }

VendrosOFbaramati.java

private void populateSpinnerVendorbaramati() {
        List<BaramatiVendorsDetails>  baramatiVendorsDetailsList =vendorBaramatiDBHelper.getAllVendorsBaramati();
        List<VendorSpinnerVO> vendorbaramatiSpinnerList = new ArrayList<>();
        for (int i = 0; i < baramatiVendorsDetailsList.size(); i++) {
            BaramatiVendorsDetails movieDetailsVO = baramatiVendorsDetailsList.get(i);
            VendorSpinnerVO movieSpinnerVO = new VendorSpinnerVO(movieDetailsVO.getVendorIdbaramati(),
                    movieDetailsVO.getVendorNamebaramati());
            vendorbaramatiSpinnerList.add(movieSpinnerVO);
        }
        if (baramatiVendorsDetailsList.size() == 0) {
            LinearLayout displayArea = (LinearLayout) findViewById(R.id.displayArea);
            displayArea.setVisibility(LinearLayout.GONE);

            LinearLayout editButton = (LinearLayout) findViewById(R.id.editButton);
            editButton.setVisibility(LinearLayout.GONE);

            LinearLayout editArea = (LinearLayout) findViewById(R.id.editArea);
            editArea.setVisibility(LinearLayout.GONE);

            LinearLayout movieSpinnerLayout = (LinearLayout) findViewById(R.id.movieSpinnerLayout);
            movieSpinnerLayout.setVisibility(LinearLayout.GONE);

        } else {
            LinearLayout movieSpinnerLayout = (LinearLayout) findViewById(R.id.movieSpinnerLayout);
            movieSpinnerLayout.setVisibility(LinearLayout.VISIBLE);
        }

我想存储供应商详细信息，并且还执行其他数据库操作。但实际上它崩溃了。
