View 2 Replies View RelatedAndroid :: View Size After Orientation Change
Jun 17, 2009Is the view aware of the orientation change in order to return updated size after a change in orientation? I'm handling the orientation myself (android:configChanges="orientation|keyboardHidden"). Does it means that I have to take into account the orientation state when querying for view.getHeight()? The view returns the same value as before the orientation change. It this the normal behavior or I should "notify" somehow the view to "refresh" its size.
View 2 Replies View RelatedAndroid :: OnMeasure Gets Called / View Doesn't Change Size
Dec 3, 2009I have a View that I've placed into a ScrollView.The View paginates text.If the text changes, then the height of this view will also change (expand or contract, depending on whether the new text takes more vertical space or less).For debugging, I draw a rectangle around the view to show its current size. After I repaginate, I cannot get Android to cause the View to change its size -- I have tried calling measure() myself, calling requestLayout(), and calling forceLayout() -- even though my overloaded onMeasure gets called, and calls setMeasuredDimension() with the correct values, the view remains the same size as it was before repagination. What am I missing?

View 5 Replies View RelatedAndroid :: Possible To Start Surface View With Game Thread
Aug 7, 2010I've read several example programs and tutorials to try and solve my problem but they all seem to go the same way. I've used a couple Activities and xml documents to create a menu that loads when my game starts.When the user clicks the "Start The Game" button, it loads a new Activity that sets the view with my game thread and all of the game properties.I know this activity works because I've run it alone as its own project, but every way I've tried to start it after the Menu,I get a nullPointerException and it force closes.I read the SurfaceViewOverlay tutorial and attempted to use that implementation, but I'm using a SurfaceView, not a GLSurfaceView.I'm debating rewriting my entire program to use OpenGL but I figured I would see if anyone else knows what I'm doing wrong here.If you need the code snippets I can paste some here, but it's not really the specific code that's wrong.

May 3, 2010I'm trying to render a 640x480 RGB565 image using OpenGL ES on Android using GLSurfaceView and Native C code. Initially I had a 0x0501 error with glTexImage2D, which I was able to resolve by changing the image dimensions. But now, in the "drawFrame" call, when I do glDrawTexiOES to resnder the texture, I'm getting the following error on the Logs: drawtex.c:89: DrawTexture: No textures enabled I'm already doing glEnable(GL_TEXTURE_2D), is there anything else I should do? Is there a complete example showing GLSurfaceView with native code using textures?
View 4 Replies View RelatedAndroid :: 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 :: Open GL Surface View Renders Black On First Start
Apr 1, 2009I have an Activity that was created based on the TriangleRenderer example. It works flawlessly as a standalone project, but when I use it as the tab of a tabhost there is a problem. At startup the whole activity is just black - I can get touch events and do everything else but it doesnt show anything. When I change the orientation (and therefore recreate the activity) it all works well. Maybe the problem comes from the View focus. My SurfaceView is not focused when created inside of the tabhost. I tried to fiddle around with the methods available in my onCreate() and onPostCreate(), but couldnt find a way to get the SurfaceView focused. The following sourcecode blocks in the guardedRun() method because needToWait() is true because !mHasFocus is true. If I exclude the ! mHasFocus, it goes on but shows a black View anyways. Do you have any idea why it does work after orientation change, but not at the first startup? The Activity looks quite simple.
View 2 Replies View RelatedAndroid :: Overlay Images Onto Camera Preview Surface View
Aug 23, 2010I have a SurfaceView that is being used to draw custom animations and I would like to overlay them onto a live-feed from the phone's camera. Currently, the SurfaceView that contains the animations has 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. Is it possible to make a SurfaceView transparent? What is the best course to pursue the use of multiple views? My end goal is to essentially overlay the contents of another SurfaceView onto the Camera SurfaceView.

Android :: How Do I Make My Image View Fixed Size Regardless Of Size Of Bitmap
Sep 23, 2010So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file

View 2 Replies View RelatedAndroid : How To Change Size / Color Of Phone Buttons?
Sep 4, 2009I would like to know the way to make a user interface for Android for people that have low vision. The idea is to make a UI with the following features: 1- Uses very very big buttons. 2 -Uses very big font size. 3- Te colors to use are basically black and white (for more contrast). 4- The icons in this UI are not relevant. 5- We must sacrifice the number of chars that we can show in the screen to get bigger labels and buttons. 6- A simple zoom system for the images should be a great idea. 7- We can use the camera of the phone to get a magnifying glass. I'm member of a blind people association in Spain and we think that this should be a great idea for begining a new low-vision-user- interface that is not aviable in the market for the new mobile phones. This will help many people that uses movile phones but have many difficulties to work with them.

The only sure way I can get it to switch to landscape view is to hold the phone vertically and then have it switch.Is there something wrong with the phone?
