I want to render 3d object on the screen. Before that I would like to compute the screen so that the rendered object can be given relative position. How that can be done?

I am a novice with Java.I have to implement an array of objects that changes in size during execution.The code I am writing is going to be ported on Android, too.According to your experience, what's the best class to implement that?

View 6 Replies View RelatedI'm currently developing my first android app, and my first game. I've been developing on a netbook with a CliqXT (HVGA). Things are going well, it renders perfectly on the smaller screen. I knew I'd have some issues when rendering on larger screens, but the issues I'm having are not what I was expecting and I'm kind of stuck.
So basically the game consists of a main SurfaceView which I'm rendering the tiled game world on to. I followed this tutorial to get started, and my structure is still pretty similar except that it calculates the boundries based on the player location:
http://www.droidnova.com/create-a-scrollable-map-with-cells-part-i,654.html
The game also has various buildings the player can enter. Upon entering it launches another activity for that particular building. The building activities are just normal Views with Android UI stuff defined in XML (Buttons, TextViews, etc).
What I expected to happen:
So I expected the the building UIs to render correctly on the larger screen. I specified all dimensions in "dp" and fonts in "sp" in hopes that they'd scale correctly. I expected the actual game tilemap to render generally correctly, but maybe be really tiny due to the higher resolution / dpi. I'm using a very similar function to the tutorial linked above (calculateLoopBorders(), my version is pasted below) to calculate how many tiles to render based on screen height and width (getHeight() and getWidth()).
What is actually happening:
The whole game is just being rendered as if it's HVGA. The tilemap, and the building UIs are just scaled down to the smaller screen size, leaving black borders around the left, right, and bottom (see images).
The FAQ mentions a method of passing objects around activities. (It is not clear to me): "A HashMap of WeakReferences to Objects. You can also use a HashMap of WeakReferences to Objects with Long keys. When an activity wants to pass an object to another activity, it simply puts the object in the map and sends the key (which is a unique Long based on a counter or time stamp) to the recipient activity via intent extras. The recipient activity retrieves the object using this key.".................

Now, I have map locations that are dynamically generated and drawn on the map at run-time to visualize some streams, Up to this point the application is working fine, Now my problem is that I am trying to filter the objects ( addresses) to visualize only the on-screen ones. I do NOT want to visualize the addresses that are off-screen. The way I am trying to do this is to check the screen-coordinates of each object (address) before visualizing it, then it the coordinates (x,y) more than (0,0) and less than (320, 460). I should visualize it. I am trying to use this approach, but it is not working for some reasons, I have tried many posts but could not understand why, there must be something missing somewhere that I am not aware of.

View 2 Replies View RelatedI am finding that performance degrades after one or more screen rotations, and I presume that this is likely to be because an App's main Activity is destroyed and recreated each time the screen is rotated and that my app must be leaking memory when that happens.I have read that, contrary to what one might expect, not all the objects created by an app's main Activity (or in classes called by that Activity) are destroyed when the activity is destroyed. Specifically, I think I have read (although I can't now find where) that if the View uses a large bitmap member object then the Activity's onDestroy() method should be over-ridden and the bitmap should be explicitly recycled.Are there other objects that need to be destroyed or removed when the Activity is destroyed? What about Listeners? Is there a comprehensive tutorial or guide on this subject?
View 1 Replies View RelatedThe View class has a compute Scroll method whose documentation states: Called by a parent to request that a child update its values for mScrollX and mScrollY if necessary. This will typically be done if the child is animating a scroll using a Scroller object. See
http://developer.android.com/reference/android/view/View.html#compute...
I am using the 1.5 SDK and I do not have access from within my application to the mScrollX and mScrollY protected member variables of the View class. However, I must have a custom scroller object for my view.
I'd like to know if there is already a way to know from a given set of markers, the zoom I should apply to the map or do I have to do it my self? (this depends on the resolution so i expected to find it in MapView because it knows its boundaries.

View 1 Replies View RelatedI am designing a home screen widget. I ran this widget on a HTC Hero device, which has a screen of 320 pixels * 480 pixels with mdpi. It ran perfect on HTC Hero. The widget takes 3 cells * 2 cells space, i.e. 240 pixels * 200 pixels.Then I ran this widget on a Nexus One device, which has a screen of 480 pixels * 800 pixels, mdpi. Since Nexus One also is mdpi, so I though 240dip is equivalent to 240 pixels on Nexus One and 200dip is equivalent to 200 pixels on Nexus One, so the widget will not take 3 cells * 2 cells space on Nexus One device. To my surprise, when running on Nexus One device, the widget take exact 3 cells * 2 cells, about 360 pixels * 300 pixels, on Nexus One device.I am confused. The layout xml above specifies 240dip in width and 200dip in height for the widget, but why did it take 360 pixels * 300 pixels on Nexus One Device? What am I missing?

View 1 Replies View RelatedFrom Android widget screen guidelines,we know that, home screen has 4*4 cells, and in portrait orientation, each cell is 80 pixels wide by 100 pixels tall. I think these are for baseline HVGA screen. How about for large screens and hdpi screens, do they still have 4*4 cells for widget and each cell in portrait orientation is still 80 pixels * 100 pixels?

But when I run my application on Samsung Galaxy S3 SGH-T999 (resolution 720x1280) throught eclipse, the following code prints "Normal screen" i.e. it is a normal screen device but according to my knowledge it should print "Extra Large screen".

View 1 Replies View RelatedI have an app that I would like to keep 1.5 compatibility but support the additional display resolutions of more recent devices like the Droid. I've read the suggestions in the dev guide, specially the legacy applications section, since that's exactly what I want to do.I'm not running in compatbility mode, so anyDensity is set to true and all screen sizes are allowed in the manifest. I've recreated all my graphical elements so they don't get upscaled on a 480px-width screen (called "hires-bitmaps" in the following).If I put the hires-bitmaps into drawable-hdpi and leave the others in drawable, the emulator2.0 (WVGA854, density @ 240) displays them perfectly. On the other hand, the emulator1.5 (320x480, density @ 160) - and my HTC Hero - ALSO use the hires graphics in drawable-hdpi. That's a problem because the hires graphics scale slightly differently and I don't want the app to resize too much.As mentioned in the dev guide I can prevent this by adding the API version number to the resource folder. Not very convenient since I'd have to keep the hires bitmaps twice (drawable-hdpi-v4 and drawable-hdpi-v5), but I nevertheless tried it. Result: emulator2.0 uses low-res graphics from "drawable" (which is bad), emulator1.5 as well (which is good). And what's weird: emulator1.6 (WVGA854, density @ 240), uses hires-graphics. Now that seems odd.

View 2 Replies View RelatedI am trying to determine the physical size of a screen in inches.
Normally, I could do something like this:
CODE:.............
Then use metrics.widthPixels and metrics.heightPixels. Now that I know the width and height in pixels, I should be able to calculate size in inches if I know the density. Easy enough, metrics.xdpi and metrics.ydpi.
Then screen dimension in inches should be:
CODE:.................
Seems simple enough except that it doesn't work.
On a Motorola Droid, the system reports back: xdpi and ydpi as 96 (which cannot be true).
And the screen resolution as: 480 x 854. Which results in a width of 5" x 8.9" -- which as I'm holding this in my hand right now, I must say - cannot be correct. how to accurately calculate this?
