Question

当我尝试使用OnClick方法填充数据库时，应用程序崩溃并出现以下错误：

05-28 10:18:44.795 24503-25060/com.example.igardini.visualposmobile E/SQLiteLog: (283) recovered 9 frames from WAL file /data/data/com.example.igardini.visualposmobile/databases/clienti_db-wal

        at java.lang.Thread.run(Thread.java:818)

以下是我的MainActivity连接到DB的内容：

    posRoomDatabase = Room.databaseBuilder(getApplicationContext(),
            POSRoomDatabase.class, DATABASE_NAME)
            .fallbackToDestructiveMigration()
            .build();




    DB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    clienti clients =new clienti();
                    clients.setID(appBODY[0]);
                    clients.setCOD(appBODY[1]);
                    clients.setRS1(appBODY[2]);
                    clients.setRS2(appBODY[3]);
                    clients.setIND(appBODY[4]);
                    clients.setLOC(appBODY[5]);
                    clients.setCIT(appBODY[6]);
                    clients.setCAP(appBODY[7]);
                    clients.setNAZ(appBODY[8]);
                    clients.setPIVA(appBODY[9]);
                    clients.setPROV(appBODY[10]);
                    clients.setCF(appBODY[11]);
                    clients.setSCON(appBODY[12]);
                    clients.setLIST(appBODY[13]);
                    clients.setIDMOV(appBODY[14]);
                    clients.setDESMOV(appBODY[15]);
                    clients.setM2(appBODY[16]);
                    clients.setMEM(appBODY[17]);
                    clients.setMAIL(appBODY[18]);
                    clients.setIDPAG(appBODY[19]);
                    clients.setDESPAG(appBODY[20]);
                    clients.setESENZ(appBODY[21]);
                    posRoomDatabase.clientiDao().insert(clients);
                }
            }) .start();
        }
    });

实际上我的应用程序只是从网站上获取HTML代码，只是通过获取数据来转换字符串，而所有数据都在一个数组字符串中，所以我只是尝试使用该数据填充数据库，但我只是我不是很喜欢android所以你能帮助我吗？

在我更改了INSERT查询后，我收到以下错误：

由于错误日志表明clienti.ID_CLI违反了UNIQUE约束。您已将clienti.ID_CLI定义为唯一。但是已经有一行给定了clienti.ID_CLI。如果clienti.ID_CLI存在任何数据，您需要先检查。如果是，请更新其他插入。这个过程应该是： -

data: getData with clienti.ID_CLI 
if(data exists)
  update 
else 
  insert

您也可以像这样更新插入方法

@Insert(onConflict = OnConflictStrategy.REPLACE)
  void insert(clienti client);

 // Insert multiple items
 @Insert(onConflict = OnConflictStrategy.REPLACE)
  void insert(clienti ... client);

尝试填充Room DB时出错
