Android :: SimpleCursorAdapter And Blobs

Mar 24, 2009

The favicon field returned by the browser bookmark provider is a sqlite blob. I want to display the bookmarks in a listview with the favicon but couldn't find a way to do it. I tried using a SimpleCursorAdapter.ViewBinder but I get an exception.

This is what my code looks like :

General :: Prop Blobs For Building CyanogenMod From Source

Feb 11, 2012

Where i can find the proprietary files for android phones (htc desire gsm specifically). The wiki says "find updated prop blobs" but has no reference as to where to even look.

I want to build a KANG for a device i have no physical access to, so i cannot extract the proprietary files.

General :: HUAWEI U8815 - Using Fastboot With CWM Backup Containing Blobs

Apr 23, 2013

I've got a HUAWEI u8815 phone stuck in boot loop - I can use Fastboot to flash BOOT.IMG and RECOVERY.IMG to it fine.

Thing is I need to flash a SYSTEM.IMG but the only backup of the System is a CWM backup that is not in *.IMG format.

It has

- system.ext4.dup
- blobs (folder - containing loads of folders and files)

Question is can I make a SYSTEM.IMG from these files... or flash the blobs - but if so how?

Android :: SimpleCursorAdapter

Jun 25, 2009

I am trying to pull data from a cursor which is initialized as follows:

Uri inboxUri = Uri.parse("content://sms/"); Cursor c = managedQuery(inboxUri, null, null, null, null);

This effectively gets me to latest text message that has been sent/ received. I am now trying to put certain fields into a listView, but need to format them before displaying them. The date is represented in the table in milliseconds and I want to convert it to a date before placing it in the list.

Here is where I am trying to place the date in my list. How can I format these fields before placing them into my listview?

Android :: AutoCompleteTextView And SimpleCursorAdapter

Apr 14, 2009

I am trying to connect a AutoCompleteTextView with a SimpleCursorAdapter, which narrows down the selection of a list of words, when the user starts typing.

Following some other posts here, I've come up with the following code, but it doesn't work. I defined a FilterQueryProvider runQuery() method for the SimpleCursor Adapter, but when I use the debugger in the code, the response from the ContentResolver.query((0 method call is null.

I think the problem is that there is no relationship between the CONTENT_URI and the SQL database, but I can't be sure.

Android :: How To Use AutoCompleteTextView With SimpleCursorAdapter

Apr 8, 2009

I have an application that involves reading a text dictionary file with about 7000 entries, and allowing the user to choose one of these. My first approach was to allow the user to select one of these by using a AutoCompleteTextView together with ArrayAdapter<String>. This works, but is very slow (~10 seconds to update the word list each time the user enters a character to narrow down the choice).

I was wondering how to rework it so that I could use a database using a SimpleCursorAdapter instead. In other words, to hope that a SQL database could provide a more efficient ordering and access for the elements. Is this the best way to do it? I've also seen several references to SQLiteDatabase, but don't know which one to use.

I found this code fragmant consisting of an extended SimpleAdapter. http://sacoskun.blogspot.com/2008/08...leadapter.html<http://sacoskun.blogspot.com/2008/08/autocompletetextview-with-simple...>

Unfortunately, this is not a complete worked out example. Could someone forward me a more complete example? I've found lots of code fragments, but no code that shows how to initialise the SimpleCursorAdapter contents, or how it works together with the AutoCompleteTextView.

I want to create a table whose primary key will be some other field and not _id . The below table gets created but the value of _id remains null :

"create table accounts ("+BaseColumns._ID+" integer , profile_name text primary key" +" name text not null);";

My doubt is wont _id get auto incremented if we do not place "+BaseColumns._ID integer primary key autoincrement+" .

Android :: SimpleCursorAdapter.bindView - And Row Views

Oct 22, 2009

I have a problem with bindView() that has me puzzled. I am using it to customize each row, including setting icons, coloring the background and setting up listeners for buttons. It mostly works as expected, but not quite.

When I fill the ListView with SimpleCursorAdapter, I get multiple calls to bindView() for position 0, but only 1 call for the other rows. The problem is that when all is said and done, I have 2 rows (LinearLayout) created for position 0. Here is a sample log extract:

CODE:........

I use a view holder class to hold the view, position and other data so that when a button is clicked, I can retrieve the holder with view.getParent.getTag(). This all works fine. The problem is that there are two views for position 0, but it's the first one in the above logcat that seems to be displayed. My code which acts on the rows when a button is clicked (especially setting background color) does not reliably hit the position 0 row that is actually displayed.

I can see what's happening but I am at a loss about what to do about it. Why are two view created for position 0? Is it something that I can control? How? If not, how should I deal with it so that the results when I modify the views are predictable?

Android :: Filtering SimpleCursorAdapter ListView

Feb 27, 2010

Since the query that comprises my ListView basically gets the rowID, name, and a third column from my databases's table, I want to be able to filter the cursor based on the partial value of the name column. However, I am uncertain of whether I can do this directly from runQuery without expanding my DB class since I want to filter the existing cursor, or will I have to create a new query function in my DB class that partially searches my name column, and if so, how would I go about creating the query statement while using the CharSequence constraint argument in runQuery?I am also concerned about the performance issues associated with trying to run multiple queries based on partial text since the DB table in question has about 1300-1400 rows. In other words, would I run into a bottleneck trying to filter the cursor?

Android :: Overrided SimpleCursorAdapter BindView Not Being Called

Mar 19, 2010

The problem is as follows: - My app is deriving from TabActivity that has 3 tabs - Each tab has a ListView - Tab1 is populated by an adapter that inherit SimpleCursorAdapter and overrided the bindView() method. This tab is displaying correctly. - Tab 2 is also populated by another adatper that inherit SimpleCursorAdapter and overrided the bindView() method. For some reason that I don't understand, the overrided bindView() is not being called. Thus the tab is not displaying correctly.

Here's my code fragment:

Android :: Extending SimpleCursorAdapter With A Custom GetViewBinder

Oct 31, 2010

Im using the NotePad example as a base for an application. This binds a ListActivity to a Provider.

Its perfect, except it uses SimpleCursorAdaptor, which means the list only binds to and displays one item per row. I want it to display two items, both bound the Provider. Or more accurately display the text from one Content Provider field and an icon which depends on the value of a different field.

This sounds like a pretty simple thing to do, a very slight modification to the NotePad application. Trouble is, I have no idea on *how* to do it. I really need a starting point, and "approach" to use.

So far I have tried (unsuccessfully):

* Hand populating the ListView by reading in the Provider data and populating an array in OnCreate. This works, except as the data is not bound the List does not update when I add an item.

* Extending SimpleCursorAdapter with a custom getViewBinder. Could still only bind to a single column.

* Building my own ListAdaptor. Couldn't get this to work.

* Concatenating both fileds together and "parsing" 2 fields into 1 field read/write.

The next thing I will try is extremely tacky running two separate simpleCursorAdaptors in two views in a Linear Layout, fudged so the row height is identical, and duplicate the logic.

I say this only to show that I really, really have tried.

How I can create a custom CursorAdaptor which binds to two fields instead of just one like SimpleCursorAdapter?

Android :: Binding Images From Assets To A SimpleCursorAdapter

Android :: Override GetView In SimpleCursorAdapter Gives NullPointerException?

I'm trying to change the content of a row in ListView programmatically. In one row there are 3 TextView and a ProgressBar. I want to animate the ProgressBar if the 'result' column of the current row is zero.

After reading some tutorials and docs, I came to the conclusion that LayoutInflater has to be used and getView() - overriden. Maybe I am wrong on this. code...

Android :: Computation On Db Data Then List Them Using Either SimpleCursorAdapter Or ArrayAdapter

Apr 23, 2010

I juststarted programming in android a few weeks ago, so I am not entirely sure how to deal with listing values. I have some questions regarding displaying data sets from db in a list. Currently I have a cursor returned by my db points to a list of rows and I want display 2 columns values in a single row of the list.

The row xml looks like this:

CODE:...............

so I was thinking using simplecursoradapter which supposedly makes my life easier by displaying the data in a list. However that is only true if I want to display the raw data. For the purpose of my program I need to do some computations on the raw data sets, then display them. I am not sure how to do that using SimpleCursorAdapter.

Here's how I display the raw data:

CODE:.........

Is there a way to do computation on the data in those rows before I bind it with the SimpleCursorAdapter? I was trying to use an alternative way of doing this by using arraylist and arrayadapter, but that way I dont know to how achieve displaying 2 items in a single row.

This is my code for using arrayadapter which only display 1 text in a row instead of 2 textviews in a row:

CODE:.......

It's very obvious that it only displays one textview in a row because I set the second arrayadapter overwrites the first one! I was trying to use R.id.text1 and R.id.text2 for them, but it gave me some errors saying 04-23 01:40:58.658: ERROR/AndroidRuntime(3309): android.content.res.Resources$NotFoundException: Resource ID #0x7f070008 type #0x12 is not valid.

Android :: Subclassing SimpleCursorAdapter To Include ConvertView For Memory Conservation?

Nov 4, 2010

I've been scouring throug the examples and tutorials but I can't seem to get my head around how to handle recycling within a subclassed SimpleCursorAdapter. I know that for regular ArrayAdapters you can check convertView for null and inflate if null from the xml and if not null, recycle, but I'm having a little trouble visualizing how that works with the from and to arrays within the SimpleCursorAdapter subclass. I tried to figure this out from the The Busy Coders Guide to Android Development by Commonsware but was unsuccessful. If anyone knows of any tips, examples, or tutorials, I would be grateful to see them.

Listview Simplecursoradapter Move To Record?

Dec 8, 2013

My app is mainly made up of a listview linked to a simplecursoradapter (custom one I might add) which in turn uses a cursor which gets the data fed in from a dbadapter class.

using the dbadapter class I can retrieve data using the rawquery and query methods no problem. However I am trying to allow the user to enter a month in and then the app will scroll to that month in the list , instead of the user having to scroll through several months to get there.

This is where I am struggling, I have tried to move to the position within the original cursor and then calling changeCursor from the simplecursoradapter with no luck and tried using the listview with smothscrolltoposition again with no luck and even tried to notifydatachangedset (probably got that named wrong) and then within the custom simplecursoradater try and move to it but that does not work either.

Android :: Android WebView Not Loading A JavaScript File But Android Browser Loads It Fine

Jun 3, 2010

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebSettings;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class myKMB extends Activity {
I already have JavaScript on the web browser on, the problem is the web view is acting to different from the web browser.
