Hi All,

Welcome All the users of Java Ranch to Book Promotion of Pro Android Web Apps.

I have gone through the Table of Contents of Pro Android Web Apps. After reading that content, I can tell that this book is very helpful for those who are looking for their Career in Mobile Applications with Android.

The persons, who are familiar with Android, can use this book for becoming more confident regarding Android Concepts.

The persons, who are new to this field, should have knowledge of Croe Java (including How to write Classes and How to use Inheritance).

This book covers all the corners or we can say all the areas which can be used to develop any Mobile Application. This also explores some APIs like Telephony and 3D Graphics with OpenGL.

@ Hardik

I think you should use relative layout in xml file in which you are creating list rows.

Hello All..

I am using custom adapter which extends simple cursor adapter in which I am overriding newvview and bindview operations.

In this I am getting from cursor from onCreate();

Initially I have 4 contacts in my DB so cursor count is 4.

But I have deleted one contact but cursor count is still 4. and my application is displaying duplicate copy of one contact at cursor position 4.

please tell me how can I manage cursor after deleting an contact from DB.

contacts details are stored in DB in table Data1.

but in Raw Contact Table, we can see one column named isDeleted. If any contact is deleted then isDeleted column contains 1 otherwise.

I think i can use it.

but I am not getting how to use it to manage cursor.

I hv to extract data from data table. that's y i m using URI of data table.

my data table consists of...

Mimetype_id Raw_Contact_id Data1
6 1 Name
6 2 Name
6 3 Name
6 4 Name
5 4 Ph. Number
5 3 Ph. Number
5 2 Ph. Number
5 1 Ph. Number

Now I have to find out the cursor.

And display the details in list view as following....

Ph. Number
Ph. Number

and so on...

In list view, each row consists of 2 text views.
first text view should contains the name of the person and the 2nd text view should contains the phone number of that person.

I have to get distinct raw contact id using content resolver.

Cursor cursor = getContentResolver().query(Data.CONTENT_URI, null, null, null, null);

in this query, 3rd parameter is selection. by passing null we will get all rows.

but i want rows with unique raw contact id.

what should i pass in selection.

Waiting for reply.

I have to display contacts in two_line_list_item.

for getting contacts details, I am using Data table.

To find cursor i m using getContentResolver() and writing a query as

Cursor cursor = getContentResolver().query(Data.CONTENT_URI, null, Data.MIMETYPE + " = 6 " , null, null);

int ct = cursor.getCount();
Log.d("Cursor","cursor count is "+ct);

but its retruning cursor as null
