  2. Hi... very nice tute... Thanks..
    I am working on a Sales App... & I want a interface where user can add items in a grid..
    e.g. In a Grid-
    1st column will be Combobox to select Item - on selecting Item all related details should be filled.

    Basically is that possible in android? And Can you please give me some idea?
    I have worked on such interface in .NET but how to do it in android? Please help..

    1. Can you Explain me more About Design??? some image or layout????

  3. This comment has been removed by the author.

  5. How to create data grid view in android.

  6. Hi all,

    I was wondering if someone could help with my understanding of this code
    in the main activity.

    db.getAllContacts(); << ?

    gridView = (GridView) findViewById(;

    ArrayAdapter adapter = new ArrayAdapter(this,
    android.R.layout.simple_list_item_1, ArrayofName);


    How does the call to db.getAllContacts retrieve the contact list into ArrayofName
    for the adapter?

    Looking at the code, I see db.getAllContacts() should return a list
    but there's no assignment to a list from this call.

    Wouldn't this cause an exception? I would expect to see list=db.getAllContacts();

    I'm confused. Thanks in advance.

  7. Nice tutorial, thanks!

    A question: your grid shows the data twice, why is that. I assume it is not in the getAllContacts method because the log just show the single entries. Could you explain that? Thank you in advance.

    1. Because,every time Activity open its insert data, that's why its showing twice...
