I am writing a class in Android that requires certain parameters from the class that calls its functions.
For Example my class is called "DoStuff"
DoStuff has 3 functions:
CODE:.....................
Is there a way for me to have canvas, tick and toggle implicetly passed to the "DoStuff" when I call on it's functions from somewhere else (that somewhere is unknown to DoStuff).

Today I met a problem, I need to pass a ArrayList<MyClass> from an activity to another. I dont know what the Intent exactly do when I use putExtra to pass in an ArrayList<MyClass> object. I guess MyClass need to implement Parcelable interface, so I just did it. But still, it does not work. Maybe I need to create a Bundle and then use Bundle's putParcelableArrayList method to put my ArrayList<MyClass> object in, and then pass this bundle as parameter of putExtra to the intent. So crazy! I am lazy, I just want to pass an ArrayList<MyClass> object simply, is there a simple way??

I have something like ,code...
I would like to pass in the 3 parameters , I am not sure (1) if it is possible and (2) what the syntax would be .
When providing a user on a mobile, a link to an android application via a web page, it is possible for params from the url to be passed to the app being installed.
I'm guessing the answer is no - but it doesn't help to ask.
The reasoning being that it would be handy for some situations to have a generic app that pulls config information from the referrer.
I can establish a connection using HttpUrlConnection.

I use an AsyncTask for loading operations that I implemented as an inner class. In onPreExecute() I show a loading dialog which I then hide again in onPostExecute(). But for some of the loading operations I know in advance that they will finish very quickly so I don't want to display the loading dialog. I wanted to indicate this by a boolean parameter that I could pass to onPreExecute() but apparently for some reason onPreExecute() doesn't take any parameters.
The obvious workaround would probably be to create a member field in my AsyncTask or in the outer class which I would have to set before every loading operation but that does not seem very elegant.
I want to implement a generic, thread save class which takes the RessourceId of an ImageView and the Url (http) where the desired image file is stored. It'll download the image and fills the src of the ImageView in the UiThread.
I thought AsyncTask would be the best thing for me. However I noticed that I only can pass one type of parameters to the doInBackground() Method. Like an Array of Urls. Is that true? What would u suggest me?
what parameters do I pass to this function? invalidate(left, top, right, bottom) for use with google map on android ?
View 1 Replies View RelatedI'm trying to create class with generics that will have ability to serialize its state using Parcelable interface.
The problem is that class has to contain constructor with single parameter - Parcel, but in my case I need to create class with additional parameters.
Besides, Parcelable.Creator doesn't allow to use generics.
Here is an example:
public class Sample<T> { ...
public Sample(Context ctx, SomeInterface iface, Parcel parcel) {...}
...}
What is the best practice to do it?
I am trying to display a dialog box in a simple Java class that is called from my main Activity but not successful. Please help me to figure it out.
I am passing the required values as parametrs.
I have two class: class MainActivity extends Activity :: Main *starting point *of Application class ShowMyDialog :: a simple java program In which I *generate an URl* and *display a dialog with WebView*.
I am passing the Acitivity from my MainActivity to this class as a parameter in function.
But I am *unable to call* the onCreateDialog method that I have *defined in the simple java class.
However, If I define the *onCreateDialog method in MainActivity, I am able to display it successfully.
What Should I pass as Parameter to the non Activity class from MainActivity class so that I am able to display the dialog as defined by showdialog method in JAVA class ???*

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.

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 have an application App1 which defines class A and uses instances of this class. What I want to achieve is - after App1 is installed on the device to be able to load App2 which defines and implements class B which is subclass of class A (imported from App1 package); and be able to get an instance of class B in the App1. Class B doesn't add any new interfaces, so using it as class A is ok. But I am not sure how to pass the instance of class B to App1 (preferrably without any user interaction).
Can anyone advise if this is feasible?
What intents do I use to pass a variable to another class? And also which intent do I use to receive it?
View 3 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?
My app has a notification that is supposed to silence itself for a day if you click on "Clear All Notifications". Every day, I see a notification pop up as expected, but after I turn my phone off for a while and then on again, the notification is done. When I check my data, I see that the "silence notification" flag is set, meaning that the service must have received an intent to clear all notifications.
The only time I ever send out that intent is via the deleteIntent (i.e. if Clear All Notifications is clicked), but I've never clicked it myself. Does the OS send that out automatically?

View 4 Replies View RelatedI'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.
