这是我的代码

 try {
            db.beginTransaction();
            String sql = "INSERT INTO " + DBHelperConstants.TABLE_DistrictMaster + " ( "
            +DBHelperConstants.KEY_DistrictCode +" , " + DBHelperConstants.KEY_DistrictName + " , "
                    +DBHelperConstants.KEY_SubDistrictCode + " , " + DBHelperConstants.KEY_SubDistrictName + " , "
                    +DBHelperConstants.KEY_MarketUID +" , " + DBHelperConstants.KEY_MarketName + " , "
                    +DBHelperConstants.KEY_SubStkUID +" , " + DBHelperConstants.KEY_Population + " ) "
                   + " VALUES (?,?,?,?,?,?,?,?);";
            SQLiteStatement statement = db.compileStatement(sql);

            for (int i = 0; i < list.size(); i++) {
                DistrictMaster districtMaster = list.get(i);
                statement.bindString(1, districtMaster.getDistrictCode());
                statement.bindString(2, districtMaster.getDistrictName());
                statement.bindString(3, districtMaster.getSubdistrictcode());
                statement.bindString(4, districtMaster.getSubdistrictName());
                statement.bindString(5, districtMaster.getMarketUid());
                statement.bindString(6, districtMaster.getMarketName());
                statement.bindString(7, districtMaster.getSubStkuid());
                statement.bindString(8, districtMaster.getPopulation());
                statement.execute();
            }
            db.setTransactionSuccessful();
            Log.w("", "Done");
        } catch (Exception e) {
            Log.w("XML:", e);
        } finally {
            db.endTransaction();
        }
    }

Answer 1

请验证，您可能忘记关闭与数据库的连接。如果数据库始终处于打开状态并且您没有关闭数据库，则无法编写任何内容。
