Android :: Filter Rows From Cursor - Don't Show Up In ListView

Jun 12, 2010

I have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.

Android :: How To Only Show Specific Elements In A Cursor Adapter

Jul 23, 2010

I have a custom CursorAdapter that is taking items from a database and displaying them in a listview. If possible, I would like to display only certain elements based on some boolean value within a database element. Here is something similar to what I would like to do:

package itp.uts.program;

import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CursorAdapter;
import android.widget.TextView;
//Adapter tests if an element is read or unread, and bolds the items that are unread
public class BoldAdapter extends CursorAdapter. Code...

Android :: Show Cursor Data In A Listview With Subsection Headings

Feb 3, 2010

I have not found an example yet with a solution to the following task.

I have a SQLite database with two tables- BOOK and AUTHOR. I execute a query on the DB that uses a join and results in a cursor that looks like this. code...

New authors and books can be added to the database at any time, and I also need the user to be able to remove books, hence the [ ] checkboxes.

So i have two row layouts, row_author.xml & row_book.xml. I detect when I need to show a row_author subheading by seeing when the current author has changed compared to the previous row. But I have realized that the rendering of an Author Row will then move the cursor forward one row and jump over their first book.

Can anyone suggest a good approach to presenting data like this? Is there a much better way to do this?

Android :: Merge Name And Tell Columns Of Cursor To Show Both In One List View?

Nov 5, 2009

I am making an app where I need to filter the contacts as user types.. I m using autoTextView and I am able to successfully query the contacts db for either tel number or name.. However while displaying I can either display name or tel number only as simple cursor only lets me match one list view with one column.. How do I merge the name and tel number column of the cursor so that both of them can be shown in one list view.

Android :: Moving Cursor Adapter Cursor Creation To Background Thread

Mar 29, 2010

The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.

Android :: Join ContentResolver Cursor With A Database Cursor

Mar 21, 2010

I get records from the system by quering a ContentResolver. I maintain the order of the items in the database. So I want to display the items in the order taken from my database.

How do I merge these two informations?

I am looking after an alternative way now. As what I ideally want is:

Get order of contacts by a custom order held in my database (this involves joining CR with my DB cursor, and doing an order by, later seams it's not possible with CursorJoiner) but there is more, if the join is not unique I want to sort by contact's name as last measure

Which is impossible using Cursor and Joiners, because of the missing feature of order bys, also I need to return a Cursor, as I will be using the in an ExpandableList

Also this translated to TSQL it would look like

select * from contactsdata
left join category on
order by category.pos asc, contact.display_name asc

So I am looking now after an alternative. I have in mind to load in a temporary DB table all data from CR, then do the query on the temporary table where I can join tables and do order bys? How does this sound to you?

Android :: ProgressBar Not Animating

Aug 26, 2010

I'm drawing a ProgressBar in a custom View (SurfaceView) to it's Canvas, and it's drawn as expected. Except that it's not animating, no matter what I do. My custom view is animated properly, but I cant change the progress of the ProgressBar.

I've created the ProgressBar like this:


And I draw it something like this (slightly simplified):


And I've tried updating it's progress manually as well:


Any ideas on what I need to do in order for my ProgressBar to animate or change it's progress.

Android :: Communicating Thread With ProgressBar

Nov 14, 2009

Here is my code:


The problem is as follows: progressBar is showing correctly. mHandler obtains the message but only once(for the first time). But I need to make it in loop(as Looper.loop should have worked in this case), so it calls mHandler handleMessage in every loop(but its not happening in this case). The outcome progressBar kept on rotating though the condition in the handleMessage (if(location!=null) )is getting satisfied in the mean time of the active progressbar. How can I make mHandle,sendEmptyMessage to call in each loop so I can check for this (if(location!=null)) condition.

Could you please advice possible reasons for this?
