[mono-android] Help with Binding EcoGallery
Hi, I'm trying to bind the EcoGallery widget in Monodroid https://github.com/falnatsheh/EcoGallery wich is a replacement of the current gallery widget with additional functionality for GCing the views. Did someone managed to successfully bind this widget ? Unil now i have managed to display it on screen, the only thing left is to bind to the eventListeners OnItemClickListener and OnItemSelectedListener Can you please give me some guidance how to do it manually? or some link where i can have a look at it?

Re: [mono-android] Enhancement code for Spinner
Hi,
hi,its glad to tell i saved spinner value(courseNumbers) in database with ur
assistance code...but when i click on retreive button now i want to populate
that spinner with courses based on the value(courseNumber) in database based
on sno...
ex data in database:
snocourseaddress
1000 303uk
1001404 india
1002505 usa
here my requiremnt is when i give value in sno edittext and click on
retreive button the data should populate in spinner and edittextfor
example i enter 1000 in sno edittext and click on retreive button the
spinner should populate with Biology and address edittext sholud populate
with ukthe spinner should set with coursename based on courseNumber in
database...
This is where the use of a dictionary object comes in handy. My original
code constructed two Lists (an int and string) which contained the
course names and course values. This was fine for my demonstration
purpose, but now we're doing searches. Of course, you can do them on
List objects and we'll use both so you can decide which works best.
A dictionary has the advantage of being a key/value system, I have a key
(say "German") and this has an associated value (505). To set up the
dictionary...
Dictionary name = new Dictionary();
where keyType is the type of object the key is (for example, string,
int, double, class, List etc) and valueType is the type of object the
value is (string, double etc).
As with a List, you add to the dictionary using the .Add method, so if I
have a Dictionary foo, it would be
foo.Add("German", 505);
There are plenty of ways to get values out of the dictionary object, but
possibly the most useful for you will be to use TryGetValue. This looks
up a given key in the dictionary and returns a value.
To get a value from foo...
int outValue = 0;
if (foo.TryGetValue("German", out outValue))
Console.WriteLine("value found = {0}, outValue);
else
Console.WriteLine("key not found");
There is a very slight performance hit using a Dictionary; it is
slightly slower than searching a list, but consider this. If I want to
search a list for a string, I can do this
if (foo.Contains("German"))
but then I have to find where in the list "German", so the code becomes
int position = 0;
if (foo.Contains("German"))
{
position = foo.IndexOf("German");
Console.WriteLine("position of German = {0}", position;
}
else
Console.WriteLine("German not found");
In effect, there are two lookups. I've not done any sort of performance
timing on using this "double lookup", but I'd expect it now to be slower
than a dictionary.
conn.Open();
SqliteDataReader sdr = cmd.ExecuteReader();
while (sdr.Read())
{
string str = Convert.ToString(sdr["SCOURSE"]);
/* here have to write the code for population of
spinner here i have taken courseNumber in string variable str...based on
this value spinner should set with course... */
Here then you would want to be using Dictionary
the parameter to search though would need to be an int, so
int strToFind = Convert.ToInt32(sdr["SCOURSE"]);
then
if (myDictionary.ContainsKey(strToFind))
etaddspinner.Text = Convert.ToString(sdr["SADD"]);
However, as you're just drawing from the database rather than anything
else, you can ignore the dictionary and use the list as before. Again
though, you will need to be using an int to look up the course number,
so the code would be
int strToFind = Convert.ToInt32(sdr["SCOURSE"]);
if (myCourseList.Contains(strToFind))
etaddspinner.Text = Convert.ToString(sdr["SADD"]);
At this point you may be wondering how to make this even more flexible.
That's simple, follow this logic
1. Set up your container(s) (either List<> or Dictionary)
2. Read in from the database the available courses and course numbers
into the containers
3. That's it
Once you've read in from the database to propagate the containers, you
don't need to do it anymore. Database access slows things down big time!

[mono-android] Android.Text.Format.DateFormat.GetDateFormat is missing
Hi. I want to format date and time in user's locale. I know about DateTimeFormatInfo class. This is phone locale info, but user can override it and set current date and time format in Settings -> Date & time. In Android we have android.text.format.dateFormat.getDateFormat and getTimeFormat. But I can't find these classes in Monodroid. Can anybody help with this issue?

Where is this type supposed to be located? Is this a .jar that's supposed to be present on your target device, like Google Maps? If so, you'll need a in your AndroidManifest.xml. Is this a .jar that's supposed to be included with your app? Then you need to add the .jar to your project with a Build action of AndroidJavaLibrary. - Jon ___ Monodroid mailing list Monodroid@lists.ximian.com UNSUBSCRIBE INFORMATION: http://lists.ximian.com/mailman/listinfo/monodroid

Even if you have plugins which don't inherit from Java types or require AndroidManifest.xml generation, you still have the linker to deal with, as the code your plugin wants to use may not actually exist as it's been linked away.

Unfortunately they are not bound at this time. We are looking into binding them in a future release. In the meantime, you could use JNI to invoke the method. IntPtr DateFormat_class; using (var d = new Android.Text.Format.DateFormat ()) DateFormat_class = d.Class.Handle; IntPtr DateFormat_getDateFormat = JNIEnv.GetStaticMethodID (DateFormat_class, "getDateFormat", "(Landroid/content/Context;)Ljava/text/DateFormat;"); IntPtr formatInstance = JNIEnv.CallStaticObjectMethod (DateFormat_class, DateFormat_getDateFormat, new JValue (c)); // ...

Bundle the assembly with your project so that everyone uses the same version.
