Where could I find any examples of rendering XML data in a ListView? i.e, the model is read from a XML file, not in an existing array or database cursors.

How do I store and retrieve a byte array (image data) to and from a SQLite database in Android?
View 1 Replies View RelatedI must be missing something simple here.I've searched around but don't think my search query is touching on the right topics to yield results. Anyhow, what I'm after is running through the array of data I bind to a ListView after a "Submit" button has been clicked.

I'm trying to bind data from my SQLiteDatabase to a ListView. I'm currently using a SimpleCursorAdapter to fill in my ListView. Unfortunately this doesn't seem to work with setting a CheckBox's checked attribute. This is how I do it now; instead of changing the CheckBox's checked status the adapter is filling in the value to the text argument, so the value is displayed right of the CheckBox as text.
Java:
setListAdapter( new SimpleCursorAdapter( this, R.layout.mylist, data,
new String[] { Datenbank.DB_STATE, Datenbank.DB_NAME }, new int[] { R.id.list_checkbox, R.id.list_text } ) );
mylist.xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01"
android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android" >
<CheckBox android:text="" android:id="@+id/list_checkbox"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:checked="false" > </CheckBox>
<TextView android:text="" android:id="@+id/list_text" android:layout_width="wrap_content"
android:layout_height="wrap_content" > </TextView> </LinearLayout>
The field in the database is of course of type boolean and I've also tried to assign an id to the checked field to fill the value in.
I'm trying to deploy an application with an existing SQLite database.I've been reading though the examples that are posted but they are always missing some part of the class. I feel like I'm trying to bake muffins but no one told me to use baking powder.Can someone post a full database helper class for depoying an SQLite database on Android? Edit : Delete old code because it doesn't work.
View 2 Replies View RelatedI have an existing SQLite database file from another project.
Where do I include the database file into my Eclipse project to have it deploy with the app.
Do I need to indicate that the database file is writable? (In the iPhone world you need to copy the database file from the app's bundle to a writable folder on the iPhone proper before first use.)
Once I have the database file on the phone, how do I tell SQLiteOpenHelper to use it? (I extend SQLiteOpenHelper in a custom class.

View 3 Replies View RelatedIs it possible to create a custom ContentProvider to
* access android existing database (e.g. Contacts, SMS)?
* extend an Exciting ContentProvider which has access to android existing database (e.g. ContactsProvider to access Contacts DB)?
Not sure of the absolute utility of this but seems as though it should be possible and useful. Can you extend ContentProvider to provide URIs representing new queries (i.e., joins across multiple tables not specified by existing URIs) for an existing system database? The alternative seems to be that I need to write a series of cursor queries then join them -- seems like a lot of unnecessary code duplication.
I have been trying this for the contacts database as an exercise, but no love so far. The crux seems to be that I cannot open a database in another package during the setup phase. Am I just completely out in left field here? It's possible as I am new to both Java and Android.
How can I display a particular array of items from a database (SQLServer) in a Spinner of Android?
View 2 Replies View RelatedI am using a listview to display items.
Currently I am passing an String array of items to it.
But I want to pass one more array and display its items alongwith the items of the first array(i.e somehow two lines of text).
How can I do that?
Currently I have a list view within it each row has a checkbox attached. I would like that once any checkbox is checked, at the bottom of the screen a view displays, and once none of the checkboxes are checked, the view automatically disappeared. Possible to do this?

View 3 Replies View RelatedI have a ListView with a scrolling issue. The Array contain a large number of items. When I try to scroll down, the listview displays the first items again. For example, if the initial view shows 12 items and I scroll down to view the next three, instead of showing 4 through 15, if shows 4 through 12 followed by 1, 2, and three. Debugging the Adapter reports that getView return 4 through 15 just as I would expect.

My ultimate goal is to retrieve specific strings from my Db and to display it then on the Listview where every string would be in each row.
View 1 Replies View RelatedI met this problem at writing contacts by API for Android 2.0 or greater. Each time I write the same contact which already exist in my account (Google account) I got some part of contact aggregated ok but other did not. For example fields like FN, N, ORG, TITLE always are in one copy but TEL, EMAIL, ADR are added extra so after 2nd writing the same contact I have to copy the same TEL or EMAIL. How to force API engine to not repeat existed data?

"This interface provides random read-write access to the result set returned by a database query." but I can't find any way to update a database with a cursor.I have started noting things like this as a sidewiki entry for the documentation page.
View 3 Replies View RelatedI'm using an autocomplete box, with suggestions provided by a SimpleQueryAdapter.Not sure if relevant, but only difference I see is that, both in the adapter constructor, as well as in runQuery(), I use a cursor returned by SQLiteDatabase#query obtained via an SQLiteOpenHelper instance.Should I be using on these cursors or not?If I don't use managed cursors, then I get "leak found" warnings ("database was created [sic] but never closed").

View 1 Replies View RelatedI wanted to fetch the title of an image which is saved in a mysql Db, I found out that you have to do this through Json, right now I am having a .php file:
PHP Code:
<?php
mysql_connect("localhost","xx","xx");
mysql_select_db("xx");
$q=mysql_query("SELECT title FROM field_title");
[Code]...
It outputs as follows:
Code:
[{"title":"titleone"},{"title":"titletwo"},{"title":"titlethree"}]
But now I am stuck, I want to put these titles in a simple arraylist but i don't know how to make the connection between the outputted data and the arraylist itself.
Code:
ArrayList<String> list = new ArrayList<String>();
for (??) {
list.add(string);
}
Is it possible to do this on an easy way?

I'm have a custom GridView Array Adapter. The problem for me is that when the grid list gets large enough to scroll off the screen the gridview and arraylist get out of sync. For instance in my case I have code that checks if an actor is of type director the text color should be red. if you scroll up and down my list enough times all the actors text in my gridview will become red. The thing is that the Gridview appearance actually looks fine its the backing data. Here is the complete class. In the code you can see where I tried to override getItem and getItemId but that didn't fix anything. Code...
