Apr 25, 2010I'm stuck on a problem and if possible I will need help from the community. I'm not looking for a ready-made solution, but something which would help me to produce the result.
I'm looking for a way to produce a dynamic activity based on a JSONArray object.
Here an example of a JSONArray object:
[ { "name": "my checkbox name",
"type": "checkbox",
"value": "one,two,three"
}
{ "name": "my edit text",
"type": "text",
"value": ""}...]
This JSONArray could be totally random. It could have 2 text views, 3 select menus, 1 text view and so on.
The goal is to iterate over this JSONArray and create the appropriate elements within my android code.
To produce the result I've thought of a simple switch which would render one by one my different JSONArray to an android widget.
But after that how could I have access of every property of every widget rendered?
Edit: I need as well to assign an event listener on some widget as taking the GPS coordinated...

Mar 29, 2010I'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here.

Jan 8, 2010I am creating a android app using LunarLander as a example.Now I need to create a few buttons which are drawn over the view.I do not want them as a seperate layout above or below the view but in the custom view.Is this possible or am I going to have to programmatically show the button images then detect the touch. The buttons I create using new never show on the app. I assume this is because I have overwritten the onDraw and the buttons are never drawn even though I call.

Android :: Cannot Create New Map View To Draw To Off Screen Bitmap
Oct 29, 2010I'm trying to create a MapView in a service (live wallpaper), but have it hidden so that I can render it to a Bitmap, and then map it to a texture to render in opengl. I have a Canvas and a Bitmap, and I intended to call myMap.draw(myCanvas) in order to get it into the correct bitmap so that I could then bind it as a texture.
When I Initialize I do the following:
myMap = new MapView(ctx, APPSTATICS.MAP_API_KEY);
I get an error:
java.lang.RuntimeException: stub at com.google.android.maps.MapView.<init> (Unknown Source)
Why I can't create a new mapview which I can use to draw to a offscreen bitmap?
Android :: How To Draw Overlay On Surface View Used By Camera?
May 29, 2010I have a simple program that draws the preview of the Camera into a SurfaceView. What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView, in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw).
This is a simplify version of the SurfaceView subclass I have:
public class Superficie extends SurfaceView implements SurfaceHolder.Callback {
SurfaceHolder mHolder; public Camera camera; Superficie(Context context) { super(context);
mHolder = getHolder(); mHolder.addCallback(this); mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
} public void surfaceCreated(final SurfaceHolder holder) { camera = Camera.open();
try { camera.setPreviewDisplay(holder); camera.setPreviewCallback(new PreviewCallback() {
public void onPreviewFrame(byte[] data, Camera arg1) { invalidar();
} } ); } catch (IOException e) {} } public void invalidar(){ invalidate(); }
public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
Camera.Parameters parameters = camera.getParameters(); parameters.setPreviewSize(w, h);
camera.setParameters(parameters); camera.startPreview(); }
@Override public void draw(Canvas canvas) { super.draw(canvas);
// nothing gets drawn :( Paint p = new Paint(Color.RED);
canvas.drawText("PREVIEW", canvas.getWidth() / 2, canvas.getHeight() / 2, p);
} }

Android :: Not Able To Draw A Transparent Image On Surface View / Fix It?
Jul 6, 2010My objective is to run a glowing animation on an image.I am changing the image alpha to produce this effect.
I have used basic AlphaAnimation provided in android framework but found that its slowing down other animations. So i extended a class from SurfaceView and created a thread to update it. ( Again here, i am manipulating alpha of the image ).
Everything seems fine, except that i am not able to draw a transparent image onto SurfaceView.Its showing black color on the transparent areas of the bitmap.code...
Android :: Simplest Way To Draw Pixels Lines / Circles On A View?
Aug 14, 2010What is the simplest way to draw pixels, lines and circles on a View?I want to move a cross cursor around, so nothing particularly intensive.I thought I could extend SurfaceView and add it to an XML and it would just work, but it just appears black, however, when I look at the layout view of localmap.xml in eclipse, the graphics appear as expected. Any ideas? My onDraw is never called on the emulator, and even calling invalidate on the class makes no difference. I shall keep trying but can anyone see anything I've missed? or is there a better way entirely? Code...
View 1 Replies View RelatedAndroid :: Gallery / Adapter View Child Draw Able State
Oct 4, 2010I am using a Gallery view where the view corresponding to each item is non-trivial and consists of text as well as multiple buttons. When I click to drag the gallery view (somewhere not on one of the buttons) the button's drawable state changes to pressed and appears as if all of the buttons are currently being pressed. Additionally, the same behavior happens for the selected state (e.g. all of the text of the child TextViews changes color). I am trying to prevent this behavior and have found the android:duplicateParentState xml attribute as well as the setDuplicateParentStateEnabled property. This seems like it should accomplish what I am trying to do, but it seems to have no effect.

View 1 Replies View RelatedAndroid :: Surface View Draw Images Overlay On Camera Preview
Aug 23, 2010I have a SurfaceView that is being used to draw images, and I would like to overlay them onto a live-feed from the phone's camera. Currently, the SurfaceView that contains the images have a white-background, but if I were to overlay them onto the phone's camera feed, they would have to be transparent. The camera and animation drawing cannot be done on the same SurfaceView. What is the best course to pursue the use of multiple views that involve managing the camera and drawing images? Is it possible to make a SurfaceView transparent?

Android :: Transition Between Data In Single Dynamic View In Android?
Jun 20, 2010Let me start out by saying that I feel like there should be a very simple way to do this, and it's entirely possible I'm missing something very simple. But all the examples I find for transition animations (push left out, push right in, etc.) deal with moving from one view to another. What about an application that only has one view, but dynamically changes the data feeding that view? The best common example of this is the base calendar app. It has identical views, but when you swipe forward or backward the date of the view transitions with a swipe animation. How do I reproduce this? Surely I don't have to inflate ViewFlippers for the same view? And if so, what is the best way to go about this?

Android :: Phone Supports Dynamic Font Resizing At All?

Sep 11, 2010right so the bottom buttons were working fine, but the next day, the back button takes me to the home screen :S so if im on facebook, press the back button, instead of going to the previous page. and i also set up the draw thing to unlock it, but as it was raining a little it said i entered it wrong too many times and asked for the google mail thing... but i really have no rememberence of making one, which is so ******* annyoying.
the only way ive found out to solve this problem is doin a phone software update, however as my bottom right button is working properly, everytime i hold it down to plug the phones usb, the phone just starts normally, so basically i cannot do the system update.
