I am trying to display an bitmap I created in and android program, but all the tutorials I find involve either Drawables or XML in order to display them. Can someone show me the steps needed to display an Bitmap in code?
This is not the entirety of the code, this is just the majority, the rest is related to getting the camera working. code...

Just wondering is there any method to do the conversion?

View 2 Replies View RelatedI'm attempting to make a simple homebrew game engine/framework in android. I have the "engine" as a library project that handles all of the graphics rendering, game activity, and whatnot. Essentially, the library project has a class GameMain which has a background image, an array of drawables, and a few functions (the most important is a run() function). The projects that use this library extend this class with their own unique run() function. The idea is that games that use the engine start with their own activity, launch the GameActivity from the library, and pass their unique GameMain child object into the library, which should run the unique run() method thanks to polymorphism.
Getting this to work, however, has been a struggle. I originally attempted to make the GameMain Serializable, which didn't appear to work. I'm now attempting to make it a Parcelable, but it does not appear to run the child objects run() function when called from the library. I'm wondering, are Parcelable objects actually capable of sending Object methods across activities? Am I going about this the wrong way, or am I just having some other weird bug I have not uncovered?

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 want to call a bitmap from a method in my main class and am unsure how to do it - I have a method: Code...
So basically, how can I place the bitmap in my detectFaces method in my main class and pass it as a bitmap on my imageview in my false class?
I'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?
So I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error:

View 5 Replies View RelatedPosted my problem here too HERE: A beginner..Im doing a school map app.
First of all I have background with 4 buttons ( level3, level4, level5, level6) I try and click all the buttons, normally after clicking 3 of it, the next one will crash.(each level button goes into a level map, whereby clicking the room image buttons, I will enter into the gallery-imageswitcher)
I have at least 5 imageswitchers in each level maps,so that about over 20 imageswitcher galleries overall.
I did all my stuffs using DRAWABLES instead of BITMAPS.. I have tons and tons of images (because its a school map, show all the photos in my school, and all those backgrounds and imagebuttons)
I did some research, and those who have problems are those using bitmap. Some of the ways that can be solved is system.gc();, and bitmap.recycle...(not so sure how to use it though)
In my main background - starttour.java Code...
PS: I have tons of images in the app; I have at least 5 imageswitcher gallerys in each level, so that kinda adds up to over 20 imageswitchers in my app.
I am developing an application which incorporates socket programming. I need to refer to the socket object created in the starting application when connected to a server in any other activity in that application .

View 1 Replies View RelatedI have some images that I loaded from a remote source stored in Bitmap variables and I want to display them. In addition to switching between these images the user should also be able to zoom and pan them. My first idea was to somehow pass them via an intent to the built-in gallery application but this doesn't seem to be possible.
A solution that is suggested in several places is using a WebView since it already supports zooming and panning.
My question is how does my Bitmap data get into the WebView? Do I have to write it to a file first, which I would have to remove again later, or is there an easier way?
Or are there even better ways to accomplish my main goal, which is displaying Bitmap data as zoomable and panable images?
