View 3 Replies View RelatedI have a class A which is responsible for fetching data from web services in android and i have a class B which is responsible for creating and rendering List View in android
Now how can i populate data on List View once the data is fetched successfully.
well i have following options but which one is better .. (if someone has anyother then i don't mind)
1) Create an intent of Class B and
pass the data that need to be
populated
2) Creating a static method int Class
B which will accept the data as an
argument and call setListAdapter
in class B i have used Holder Patter to create ListActivity. ( for reference List14.java in samples of Android )
I am developing an app that connects to a server. For that connection I created a class Client that maintains info about the connection . My app consists of several Activities and each of that Activity needs access to the Client object to communicate to the server. 1) Can I put somewhere the Client object so that all Acitvities have an access to it? 2) If not I would probably need to pass the object to each Activity via Intent.putExtra(). But putExtra doesn't accept Object as an argument. It only accepts several types like int, long, String etc. So how can I pass an object to another Activity?
View 2 Replies View RelatedI'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?
I often run into the following dilemma: I need some singleton-like object in my app (typically some central manager-like thing) and this object needs a context for various things. This means that I either have to pass a context to all methods needing one or have some sort of init-pattern to the object. Neither is pretty I think. What is the correct way of doing this? Or is this simply (even the definition of) a Service?
View 15 Replies View RelatedIn order to communicate with the server I need a huge global object (class with some hashmaps). all my activities (about 10) need that huge global object. which options do I have? I am thinking about passing the object using intends and about the possibility to make the object a singleton. using the db will be much too slow.

View 2 Replies View RelatedI have an Object that I need to be able to pass between Activites. It implements Parcelable and I've written all the code related to that. The problem is that one of the properties of the Object is a Drawable - and really needs to be. Unfortunately, Drawable is neither Parcelable or Serializable. I don't understand how to pass it. The reason for having the Drawable is that I need to cache an Image that I've downloaded from the internet at runtime. I don't want to cache the images on the filesystem, since this would potentially end up using up a lot of space over time. I'm putting the image into a Drawable so that I can easily put it into an ImageView.

How can I pass this Bitmap object from the sub-activity (the one which is going to be launched)?
I have read posts on passing arrays from and to activities, but I am confused as to how I would do it for my specific case.
I have an array of objects called DaysWeather (a DaysWeather[] array) where the objects have several String attributes as well as a bitmap attribute. I read somewhere that you have to make it serializable or parceable or something, but it seems messy at first glance.
Could someone lead me in the right direction?

Is it possible to pass a JavaScript object from JavaScript to Java using addJavascriptInterface()? Something along these lines: var javaScriptObject = {"field1":"string1", "field2":"string2"}; JavaScriptInterface.passObject(javaScriptObject); How would such a call be captured on the Java side? I have no problem setting up the interface to send a string, but when I send an object, I receive null on the Java end.

View 3 Replies View RelatedI'm working on an application that requires non-serializable objects to be passed between Activities. The following page suggests using a HashMap of WeakReferences to accomplish this:
http://developer.android.com/guide/appendix/faq/framework.html
Is this solution safe? I know Activities are completely destroyed and recreated when the screen orientation changes. Couldn't those weakly referenced objects get GCed in the split second when the screen is rotated, since they wouldn't be referenced elsewhere at that point?

Class AddText(extends Activity), Grafitti(extends MapActivity) and MarkerOverlay. Grafitti calls AddText, and AddText opens a new Activity that gets an input from user (EditText), then when that is successful Grafitti calls MarkerOverlay. The problem is I can't access the input in AddText. I need to use that input in MarkerOverlay, I tried creating a setter and getter but it won't work. (error) I've tried searching the web and I think the solution is Bundle. I'm having a hard time understanding how Bundle works. Is there any other way? or any code snippet on how to use Bundle. A code snippet would really help me a lot.

But the ItemID is always 0. Before I've only one gridview and then I passed the item's position. But now I've 3 different gridviews and I don't know if the position of item selecte it's from gridview 1,2 or 3. I supose that the great solutin it will be to pass the id resource (image) but I don't know how to pass it. Can you help me?
