Android 转义引号时发生SQL语法错误

好的，我正在为我的同学们构建一个应用程序，该应用程序从我的在线mysql数据库获取程序，并将其存储在本地sqlite数据库中

但它给了我一个错误，我尝试转义双引号和单引号以及验证我的查询，但我的应用程序仍然崩溃，并给我一个错误

现在代码是用“c”语言编写的，因此包含switch case语句，当switch case语句中出现单引号时，问题就出现了

用于转义引号的代码：

public static void fromJSON(JSONArray jsonArray){

    try {
        String code;
        SplashScreen.titles.clear();
        SplashScreen.codes.clear();
        int length = jsonArray.length();
        for (int i = 0; i < length; i++) {

            SplashScreen.titles.add(jsonArray.getJSONObject(i).getString("title"));
            code = jsonArray.getJSONObject(i).getString("code");
            code = code.replaceAll("\'","\\\\\'");
            code = code.replaceAll("\"","\\\\\"");
            SplashScreen.codes.add(code);

        }
    }catch (Exception e)
    {
        Log.d("Practice", e.toString());
    }

}

publicstaticvoidfromJSON（JSONArray-JSONArray）{
试一试{
字符串代码；
SplashScreen.titles.clear（）；
SplashScreen.code.clear（）；
int length=jsonArray.length（）；
for（int i=0；i

SQLite语句是：

public void updateDatabaseWithUpdate(String tableName)
{
    SQLiteDatabase SPADatabase = this.openOrCreateDatabase("myDatabase", MODE_PRIVATE, null);

    Log.d("getUpdateData", "Updating database : "+tableName);

    //SPADatabase.execSQL("DELETE FROM "+tableName);

    for(int i = 0; i<titles.size(); i++) {
        Log.d("trialanderror", codes.get(i));
        SPADatabase.execSQL("INSERT INTO " + tableName + " (title,code) VALUES ('" + titles.get(i) + "','" + codes.get(i) + "')");
    }

    //Toast.makeText(this, tableName+" Database updated!", Toast.LENGTH_SHORT).show();

    setLocalCounts();

    //Log.d("dbCount", tableName+" dbCount = "+dbCount);


}

public void updateDatabaseWithUpdate（字符串tableName）
{
SQLiteDatabase spadabase=this.openOrCreateDatabase（“myDatabase”，MODE_PRIVATE，null）；
Log.d（“getUpdateData”，“更新数据库：“+tableName”）；
//execSQL（“从”+tableName中删除”）；
for（inti=0；iSQL不是C，并且不使用C转义规则

在SQL字符串中，双引号不能转义，单引号必须加倍

但是，为了避免此类格式问题，最好使用参数（这些值根本不需要转义）：

或者通过使用来避免编写SQL命令。
