我有一个Digital Survey的Android应用程序，我的应用程序从服务器（mysql-php）获取数据并显示在Activity中。我怀疑的是如何将数据保存到数据库，因为我动态生成了问题和答案选项。
以下是活动类的代码
public void onPostExecute(String result) {
pDialog.dismiss();//ocultamos progess dialog.
//paring data
String id_preg;
String preg;
String tipopreg;
String tipo_opc;
String descri_op;
String id_pregunta = null;
String pregunta = null;
String tipo_pregunta = null;
String tipo_opcion = null;
String descrip_opc;
try{
JSONArray jArray = new JSONArray(result);
JSONObject json_data=null;
String[] tipopregu=new String[jArray.length()];
String[] tipopcion=new String[jArray.length()];
String[] id_preguntas=new String[jArray.length()];
String[] descripcion_opc=new String[jArray.length()];
String aux1="";
String aux2="";
String aux3="";
String aux4="";
String auxtipoopc;
int cont=1;
int cont2=0;
//validate the values not repeteated because
for(int i=0;i<jArray.length();i++){
json_data = jArray.getJSONObject(i);
//Get DAta
id_preg =json_data.getString("ID_PREGUNTA");//IS QUESTION ID
preg = json_data.getString("DESCRIPCION");//DESCRIPTION
tipopreg=json_data.getString("TIPO_PREGUNTA"); //TYPE OF QUESTION
tipo_opc=json_data.getString("ID_TIPOOPC");//VALUE OF ID TYPE OPTION
auxtipoopc=tipo_opc;
descrip_opc=json_data.getString("DESCRIP_OPC");//DESCRIPTION OF VALUES USED IN MULTIPLES VALUES
