Save arrayList Hashmap in database

How to save ArrayList< HashMap< String, String>> in database?
Getting NULL values in the database
I tried this method: Saving records into the database from the hashmap in android
but didn't help
public void addQuote(Quote q, ArrayList<HashMap<String, String>> put_q_list)
{
try{
myDataBase=this.getWritableDatabase();
ContentValues values=new ContentValues();
values.put("q_customer_name", q.getCustomer_name());
values.put("q_customer_email", q.getCustomer_email());
values.put("q_b_street", q.getBilling_street());
values.put("q_b_city", q.getBilling_city());
values.put("q_b_state", q.getBilling_state());
values.put("q_b_zipcode", q.getBilling_zipcode());
values.put("q_b_country", q.getBilling_country());
values.put("q_s_street", q.getShipping_street());
values.put("q_s_city", q.getShipping_city());
values.put("q_s_state", q.getShipping_state());
values.put("q_s_zipcode", q.getShipping_zipcode());
values.put("q_s_country", q.getShipping_country());
values.put("q_day", q.getDay());
values.put("q_month", q.getMonth());
values.put("q_year", q.getYear());
values.put("q_total", q.getTotal());
values.put("q_discount", q.getTotal_discount());
myDataBase.insert("quote",null,values);
}catch(Exception e)
{
Log.e("bderror",e.toString());
e.printStackTrace();
}
String selectQuery = "SELECT quote_id FROM quote WHERE q_customer_email=?";
Cursor cursor = myDataBase.rawQuery(selectQuery, new String[] {q.getCustomer_email()});
int i=0;
while(cursor.moveToNext())
{
i=cursor.getInt(0);
}
cursor.close();
myDataBase.beginTransaction();
for (int j = 0; j < put_q_list.size(); j++) {
HashMap<String, String> map = new HashMap<String, String>();
map = put_q_list.get(j);
//Each value by using this method
String item_code = map.get("item_code_final");
ContentValues cv = new ContentValues();
cv.put("quote_id", i);
cv.put("q_item_code", item_code);
myDataBase.insert("q_item", null, cv);
}
myDataBase.setTransactionSuccessful();
myDataBase.endTransaction();
myDataBase.close();
}
Only the value of "i" is being inserted!!! not the item code
Please help!!!

try this. It should work.
for (int i = 0; i < mapList.size(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
map = mapList.get(i);
ContentValues cv = new ContentValues();
cv.put("quote_id", i);
cv.put("q_item_code", map.get("item_code_final"));
cv.put("q_item_desc", map.get("desc_final"));
cv.put("q_item_price", map.get("item_price_final"));
cv.put("q_item_qty", map.get("item_qty_final"));
cv.put("q_item_tax", map.get("item_tax_final"));
cv.put("q_item_discount", map.get("item_discount_final"));
db.insert("tablename", null, cv);
}
db.close();

You should first declare an Database instance to deal with and begin the transactions. as following
SQLiteDatabase db = mDbHelper.getDatabase();
db.beginTransaction();
Then perform the loop
for(HashMap<String, String> map : mylist){
ContentValues cv = new ContentValues();
cv.put(FILE_NAME, map.get(FILE_NAME));
cv.put(DESC, map.get(DESC));
cv.put(UPLOADED_BY, map.get(DATE_UPLOADED));
cv.put(ACTION, map.get(FILE_NAME));
cv.put(ID, map.get(ID));
cv.put(FILE_URI, map.get(FILE_URI));
db.insert("tablename", null, cv);
}
Then close the cursor
db.setTransactionSuccessful();
db.endTransaction();
db.close();
That was clear in your link in the accepted answer

Getting the value of the ArrayList<HashMap<String,String>> for display

Hi I just want to know better on how to use this. Since I'm using this kind of method in doing my custom listView now I wanted to apply it since I love the approach on this but I don't know how I should do it. Anyway What I have is a database query where I get all the result from a search query in SQLite Database. Now I'm sure about the content of my query since I already tested it but when I display it the result always return the same output which is the last row of the query. For better understanding here's my code:
public ArrayList<HashMap<String,String>> getList(String search_param){
SQLiteDatabase db = this.getWritableDatabase();
ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
HashMap<String,String> hashmap = new HashMap<String,String>();
String query_select = "SELECT column1, column2 FROM tablename WHERE column2 LIKE '%"+ search_param +"%';";
Cursor cursor = db.rawQuery(query_select,null);
if (cursor.moveToFirst()) {
do {
item_list.put("column1", cursor.getString(0));
item_list.put("column2",cursor.getString(1));
list.add(hashmap);
} while (cursor.moveToNext());
}
cursor.close();
return list;
}
now to retrieve the list here's what I tried so far:
ArrayList<HashMap<String,String>> new_list;
DatabaseClass db = new DatabaseClass(getActivity());
new_list = db.getList("");
for(int i=0;i<new_list.size();i++){
HashMap<String,String> content = new HashMap<String, String>();
content = new_list.get(i);
Log.v("The hashmap",content.get("column1").toString());
Log.v("The hashmap",content.get("column2").toString());
}
now the content of my Database should be 1,2,3 for column1 and test1,test2,test3 for column2. but what I get from the result are 3,3,3 and test3,test3,test3
I also tried the method of doing
newlist.get(i).get("column1").toString; but it doesn't even solve the problem.
Any idea on what I should do about this?

Within do while you need to create instance for hashmap,
public ArrayList<HashMap<String,String>> getList(String search_param){
SQLiteDatabase db = this.getWritableDatabase();
ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
HashMap<String,String> hashmap;
String query_select = "SELECT column1, column2 FROM tablename WHERE column2 LIKE '%"+ search_param +"%';";
Cursor cursor = db.rawQuery(query_select,null);
if (cursor.moveToFirst()) {
do {
hashMap = new HashMap<String,String>();
hashMap.put("column1", cursor.getString(0));
hashMap.put("column2",cursor.getString(1));
list.add(hashmap);
} while (cursor.moveToNext());
}
cursor.close();
return list;
}

This works like charm with me
public ArrayList<HashMap<String, String>> getList(String search_param){
ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
String query_select = "SELECT column1, column2 FROM tablename WHERE column2 LIKE '%"+ search_param +"%';";
Cursor cursor = db.rawQuery(query_select,null);
int colCount = cursor.getColumnCount();
int rowCount = cursor.getCount();
if (cursor.moveToFirst()) {
do {
HashMap<String, String> col = new HashMap<String, String>();
int size =cursor.getColumnCount();
for (int i = 0; i < size; i++) {
col.put(cursor.getColumnName(i), cursor.getString(i));
}
list.add(col);
} while (cursor.moveToNext());
}
if (cursor != null && !cursor.isClosed()) {
cursor.close();
}
return list;
}

Android : retrieve all data from database and store in ArrayList<HasMap<String, String>>

I try to retrieve all data from database and put into arraylist of hasmap
but i get only the last record of table.
here is my code :
databaseAirport myDbHelper = new databaseAirport(this);
myDbHelper.open();
Cursor c = myDbHelper.selectAll();
HashMap<String, String> map = new HashMap<String, String>();
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String,String>>();
if(c!=null && c.moveToFirst())
{
do
{
map.put(KEY_ACODE, c.getString(5).toString());
map.put(KEY_FNUM, c.getString(6).toString());
map.put(KEY_STOP_1, c.getString(8).toString());
map.put(KEY_FTIME, c.getString(7).toString());
map.put(KEY_REMARK, c.getString(10).toString());
map.put(KEY_REM_COM, c.getString(11).toString());
dataList.add(map);
}while(c.moveToNext());
}
At the end, my dataList(map) retrieve the last record only...
Can anyone help me please..

Move this line as follow: HashMap<String, String> map = new HashMap<String, String>();
databaseAirport myDbHelper = new databaseAirport(this);
myDbHelper.open();
Cursor c = myDbHelper.selectAll();
HashMap<String, String> map;
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String,String>>();
if(c!=null ){
c.moveToFirst();
while( cur.isAfterLast() == false )
{
map = new HashMap<String, String>(); // <---- moved here
map.put(KEY_ACODE, c.getString(5).toString());
map.put(KEY_FNUM, c.getString(6).toString());
map.put(KEY_STOP_1, c.getString(8).toString());
map.put(KEY_FTIME, c.getString(7).toString());
map.put(KEY_REMARK, c.getString(10).toString());
map.put(KEY_REM_COM, c.getString(11).toString());
dataList.add(map);
c.moveToNext();
}
}

Change your code like this
databaseAirport myDbHelper = new databaseAirport(this);
myDbHelper.open();
Cursor c = myDbHelper.selectAll();
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String,String>>();
while(c.moveToNext());
{
HashMap<String, String> map = new HashMap<String, String>();
map.put(KEY_ACODE, c.getString(5).toString());
map.put(KEY_FNUM, c.getString(6).toString());
map.put(KEY_STOP_1, c.getString(8).toString());
map.put(KEY_FTIME, c.getString(7).toString());
map.put(KEY_REMARK, c.getString(10).toString());
map.put(KEY_REM_COM, c.getString(11).toString());
dataList.add(map);
}
