becouse I think you dont bind that components with findViewById:
shopText.getText().toString();
String deal = dealText.getText().toString();
String location = locationText.getText().toString();
String website = websiteText.getText().toString();
String category = categoryText.getText().toString();
result should be a NullPointerException.
Show us youre LogCat...
Otherwise add this to youre on create and try it again:
shopText= (EditText)findViewById(R.id.THE_ID);
dealText= (EditText)findViewById(R.id.THE_ID);;
locationText= (EditText)findViewById(R.id.THE_ID);;
websiteText= (EditText)findViewById(R.id.THE_ID);;
categoryText= (EditText)findViewById(R.id.THE_ID);;

First of all get all EditText By id.
try{
shopText=(EditText)findViewById(R.id.shopText)
//get All EditText by id like above
dbAdapter.open();
String shop = shopText.getText().toString();
String deal = dealText.getText().toString();
String location = locationText.getText().toString();
String website = websiteText.getText().toString();
String category = categoryText.getText().toString();
//secondly
dbAdapter.insertDeal(shop,deal,location,website,category);
}

I'm trying to populate this gridview with data stored in the database, everything compiles fine, but in the app i get an error saying that data from Col-1 (the id column) cannot be retrieved.
this is the gridviewactivity.java class mentioned in the above code:
public class GridViewActivity extends MainActivity
{
private GridView gridTable;
private ArrayList<String> moduleList;
private ArrayAdapter<String> adapter;
private Cursor data;
DatabaseHelper timetableDB;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState); setContentView(R.layout.gridview);
//GridView
gridTable=(GridView) findViewById(R.id.gridTable);
String id, code, day, time, duration, type, room;
id = ""; code = ""; day = ""; time = "";
duration = ""; type = ""; room = "";
timetableDB = new DatabaseHelper(getBaseContext());//getting the context object
timetableDB.getAllData();
try
{
//for holding retrieve data from query and store in the form of rows
Cursor data=timetableDB.getAllData();
moduleList = new ArrayList<>();
//Move the cursor to the first row.
if(data.moveToFirst())
{
do
{
id = data.getString(data.getColumnIndex ("id"));
code = data.getString(data.getColumnIndex ("code"));
day = data.getString(data.getColumnIndex ("day"));
time = data.getString(data.getColumnIndex ("time"));
duration = data.getString(data.getColumnIndex ("duration"));
type = data.getString(data.getColumnIndex ("type"));
room = data.getString(data.getColumnIndex ("room"));
//add in to array list
moduleList . add(id);
moduleList . add(code);
moduleList . add(day);
moduleList . add(time);
moduleList . add(duration);
moduleList . add(type);
moduleList . add(room);
}
while(data.moveToNext());//Move the cursor to the next row.
adapter = new ArrayAdapter<>(getApplicationContext(),
android.R.layout.simple_spinner_item,moduleList);
gridTable.setAdapter(adapter);
}
else
{
Toast.makeText(getApplicationContext(),
"No data found", Toast.LENGTH_LONG).show();
}
}catch(Exception e)
{
Toast.makeText(getApplicationContext(),
"No data found "+e.getMessage(), Toast.LENGTH_LONG).show();
}
timetableDB.close();
}
}
am i using the cursor correctly in this class?
thanks!

am i using the cursor correctly in this class?
Yes, but problem is creating ArrayAdapter in wrong place.
Create object of ArrayAdapter after adding all items in moduleList ArrayList from Cursor.like:
do{
// add items in moduleList
}
while(data.moveToNext());//Move the cursor to the next row.
// create ArrayAdapter object here:
adapter = new ArrayAdapter<>(getApplicationContext(),
android.R.layout.simple_spinner_item,moduleList);
// call setAdapter
gridTable.setAdapter(adapter);

The "id" column doesn't exist.
When you're creating the database you're using "ID" as the column name and not "id" so when you're calling data.getString(data.getColumnIndex("id")); it won't be able to find the column.

how to display one row from SQLite database to textview/edittext

I'm very new to android and about to create an app which holds customers and then related to it some actions.
My current unsolvable problem: After inserting customer data into database I want to switch the view and display the last entry with all fields. The inserted values like title, name but also automatically created fields like id and date. I can see that the data are in the database when I pull the database file from the DDMS but I don't know how to retrieve and display them in the desired view.
I saw dozens of examples for passing it to a listview but I couldn't find any example which would suit my needs. Maybe it's because I don't know how to ask correctly for it. If so, please point me in the right direction.

public static final String COLUMN_CUSTOMER_TITLE = "title";

I'm looking for a solution to implement this view with the last entry into my CustomerHelperClass so that I can also modify or delete this entry.
For Inserting new customer I have add_new_customer.xml and I want to switch view to update_customer.xml with the last entry displayed. Both of them have the text fields for title, name etc
update_customer.xml

Hopefully you can build upon this answer, if you need further guidance, feel free to comment.
Let's assume you want the EditText with id ntxt_first_name to be populated with customer name. You'd write this code after you call displayLastCustomer()
DatabaseHelper dbHelperInstance = new DbHelper(this); //Assuming it's running in an Activity
Cursor cursor = dbHelperInstance.displayLastCustomer();
if(cursor != null) {
EditText editTextFirstName = (EditText) findViewById(R.id.ntxt_first_name);
editTextFirstName.setText(cursor.getString(cursor.getColumnIndex(DbHelper.COLUMN_CUSTOMER_FIRST_NAME)));
}
The above snippet tries to find the View (EditText) with id ntxt_frist_name within the inflated View hierarchy that was supplied using the setContentView(int resourceId) method (hopefully you have supplied R.layout.update_customer as its parameter. Then it simply sets its mText field to the value it obtains from the entry cursor is currently pointing at (set to last entry in the query by your displayLastCustomer() method) for the column DbHelper.COLUMN_CUSTOMER_FIRST_NAME.
Like I already wrote, I hope you can get from this snippet how to populate other Views obtaining data from other columns in your Cursor object.
Cheers and good luck!
EDIT: In case you are not running this code inside an Activity object (or object of a class derived from it) , you need to obtain the Context of the Activity which has the update_customer.xml file inflated.

THANKS IN ADVANCE.

You need to pass Activity context on SqlHandler like:
SqlHandler db = new SqlHandler(youractivity.this);
in Button onclick()
And also Remove OnClickListener onClickListener() from SqlHanlder Constructer like:
public SqlHandler (Context con) {
super(con, DATABASE_NAME, null, DATABASE_VERSION);
}
