Java android解析json，删除并将值插入数据库

java android json sqlite

Java android解析json，删除并将值插入数据库,java,android,json,sqlite,Java,Android,Json,Sqlite,我试图通过调用在数据库类中创建的delete和insert方法来更新值。然而，这并没有像我预期的那样起作用。每当调用delete方法的活动被执行并给出空值时，以及当该活动第二次调用时，它将具有该值（我使用toast文本获取该值，并用try and catch将其包围，这将给出异常无效索引#（直到最后一个索引为止，数组列表索引为零）的大小为零）。但是，我使用asynctask执行此任务，以下是我尝试执行的操作： @Override protected Void doInBackgr

在这里叫它：

for (int i = 0; i < Erates.length(); i++) {
JSONObject c = Erates.getJSONObject(i);
    int id = c.getInt(TAG_ER_ID);
    int tenor = c.getInt(TAG_ER_TENOR);
    String ko = c.getString(TAG_ER_K);
    String co = c.getString(TAG_ER_C);
    double rate = c.getDouble(TAG_ER_RATE);
    double ratedb = c.getDouble(TAG_ER_RATE_DB);
    databaseMaster2.checkErates(id, tenor, ko, co, rate, ratedb);
        if(databaseMaster2.checkErates(id, tenor, ko, co, rate, ratedb) == true){
            databaseMaster2.deleteEntryEffectiveRate(id);
            }
            else {
               databaseMaster2.saveEntryEffectiveRate(id, tenor,ko,co,rate,ratedb);
                        }

问题是：

当调用活动时，它将删除行中的值，然后当第二次调用它时，它将插入值。有什么建议/想法吗

在我运行并重新运行应用程序几次后，它会导致内存泄漏，并说db从未关闭过。在哪里放置

closeDB（）或关闭（）正确吗


注意：解析JSON工作得很好。如果你问我是否确定，答案是肯定的。证明
更新问题1：删除和插入也可以很好地工作，我尝试做的是删除行，如果行为空，则插入，否则它将插入（如果其已为空）。但在第一个名为“删除”的活动时，它恰好会给出空值，当我关闭该活动并再次调用它时，它将运行将插入数据的“其他”条件。问题是，如果用户运行应用程序两次，值就会出现，如果用户只运行一次，则没有值
更新问题2：尝试根据答案执行此操作：
for (int i = 0; i < Erates.length(); i++) {
                        JSONObject c = Erates.getJSONObject(i);
                        int id = c.getInt(TAG_ER_ID);
                        int tenor = c.getInt(TAG_ER_TENOR);
                        String ko = c.getString(TAG_ER_K);
                        String co = c.getString(TAG_ER_C);
                        double rate = c.getDouble(TAG_ER_RATE);
                        double ratedb = c.getDouble(TAG_ER_RATE_DB);
                        boolean boolCheckErates = databaseMaster2.checkErates(
                                id, tenor, ko, co, rate, ratedb);
                        // close connection here
                        databaseMaster2.closeDB();
                        if (boolCheckErates) {
                            databaseMaster2.deleteEntryEffectiveRate(id);
                            // close connection here
                            databaseMaster2.closeDB();
                        } else {
                            databaseMaster2.saveEntryEffectiveRate(id, tenor,
                                    ko, co, rate, ratedb);
                            // close connection here
                            databaseMaster2.closeDB();
                        }
                    }

for（int i=0；i

在多次重新运行应用程序后，会出现以下错误：
