Save data from Json object to Database (SQLite)

Question

I am newbie in Android, so I can not estimate how do I save data in database(SQLite) that were got from httprequest through Json.
Here is my code:

Answer 1

DataBean.java class create for getter and setter method

    public class DataBean {

        private String item_type = null;
        private String change_number = null;

        public String getItem_type() {
            return item_type;
        }
        public void setItem_type(String itemType) {
            item_type = itemType;
        }
        public String getChange_number() {
            return change_number;
        }
        public void setChange_number(String changeNumber) {
            change_number = changeNumber;
        }


    }

in your Activity class..set value in object and insert into database

        private DatabaseHelper mDbHelper;
        DataBean dataBean;
        private Cursor mNotesCursor;
        private NewsCursorAdapter adapter = null;

            mDbHelper = new DatabaseHelper(this);
            ArrayList<DataBean> liststck = new ArrayList<DataBean>();



        for(int i=0;i<data4.length();i++){                      

               JSONObject e = data4.getJSONObject(i);

                 dataBean = new DataBean();

               dataBean.setChange_number(e.getString("eqid"));
               dataBean.setItem_type(e.getString("magnitude"));

                   liststck.add(dataBean);

               }  


            mDbHelper.deleteRecords();
            for (DataBean dataBean : liststck) {
                mDbHelper.insertdata(dataBean);
            }
            mNotesCursor = mDbHelper.retrievedata();
            startManagingCursor(mNotesCursor);

            adapter.changeCursor(mNotesCursor);
            adapter.notifyDataSetChanged();

you must create NCursorAdapter class for dispay result(like custom listview). here data.xml file is your custom layout. which content two textview.... "key_no" and "key_item" your database table column name...

    public class NCursorAdapter extends CursorAdapter {

        private Cursor mCursor;
        private Context mContext;
        private final LayoutInflater mInflater;


        public NCursorAdapter(Context context, Cursor c) {
            super(context, c);
            // TODO Auto-generated constructor stub
            mInflater = LayoutInflater.from(context);
            mContext = context;
        }

        @Override
        public void bindView(View view, Context context, Cursor cursor) {
            // TODO Auto-generated method stub
            TextView title = (TextView) view.findViewById(R.id.title);
            title.setText(cursor.getString(cursor.getColumnIndex("key_no")));

            TextView date = (TextView) view.findViewById(R.id.date);
            date.setText(cursor.getString(cursor.getColumnIndex("key_item")));

        }

        @Override
        public View newView(Context context, Cursor cursor, ViewGroup parent) {
            // TODO Auto-generated method stub
            final View view = mInflater.inflate(R.layout.data, parent, false);

            return view;
        }

    }

in your database class insert data and retrieve data

public Long insertdata(DataBean dataBean) {
        ContentValues contentValues = new ContentValues();
        contentValues.put(KEY_NO, dataBean.getChange_number());
        contentValues.put(KEY_ITEM, dataBean.getItem_type());
        return sqliteDatabase.insert(DATABASE_TABLE, null, contentValues);
    }


public Cursor retrievedata() {
            return sqliteDatabase.query(DATABASE_TABLE, new String[] { KEY_ROWID,KEY_NO, KEY_ITEM }, null,null);

        }

I hope it is useful for your application.
