Android :: PNG Transparency And OpenGL ES
May 27, 2009I am rendering this PNG with no transparency just fine: http://n4te.com/temp/test.png However if I try to render this PNG (with transparency) with the exact same code, I just get a white box: http://n4te.com/temp/ball.png
I am loading the PNG into a texture like this: Bitmap bitmap = BitmapFactory.decodeStream(input); int[] temp = new int[1]; gl.glGenTextures(1, temp, 0); textureID = temp[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, textureID); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_NEAREST); // GL_LINEAR for quality. gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle();
I am using this blending: gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); How is it possible to render a PNG with transparency in OpenGL ES?

Android :: Poor Transparency On Images
Apr 2, 2010I am having problems getting transparency to work well on an ImageView. The images at(http://img265.imageshack.us/img265/6233/whatn.png) were screen captured from a Droid (hdpi). The top image I made in Photoshop and left the background white. The bottom image is the same image with the background transparent and the layout's color (white) shows through. Whenever I have transparent backgrounds in images it dithers shadows like this. Also, it only happens on hdpi devices, on my G1 (mdpi) it looks just fine. What is going on? How can I make the bottom image look as good as the top one?

Apr 25, 2009I have a lot of Views where I have set a background image on the top LinearLayout and then I have nested a new linear layout below with a background that is semi-transparent. This works great in 1.1, but in 1.5 the transparency is just disregarded and this breaks my app as the text on top is now unreadable.
Is this a bug or a feature? Is there a better way of doing this? Very grateful for any tips!

Android :: Using GlColor To Set Textures To Half Transparency?
Nov 19, 2010Basically I have a fully functional ogl program (2D game) in opengl es 1.1, everything works fine except for one problem: glcolor
I'm trying to set some of my texture to half transparent and I would like to do it as follows;
gl.glColor4f(1f, 1f, 1f, .5f);
obj.draw(gl);
...
gl.glColor4f(1f, 1f, 1f, 1f);
I'm using VBO for my vertice, my textures and indices. (if that is relevant)
the problem is that nothing gets set to 50% transparency...
I'm don't think relevant to post all my code (mainly because it is spread out several classes with several GL options changing (blends, scissors etc etc).
What I would like is for people to tell me what state of OGL could prevent glcolor form working like I want, what functions should I check, what state should I call.

View 4 Replies View RelatedAndroid :: How To Paint Transparency - Swiss Cheese Style
Apr 4, 2010To explain i have a bitmap which is constructed as follows
Paint a rectangle color yellow I want now to paint a smaller circle over the top of the rectangle, but i want to use transparency. so that the circle results as a hole in the rectangle. {like swiss cheese with holes }
So if i painted the bitmap over a background the background would still be visible in the Circle/hole.
setting the drawcolor drawColor(Color.TRANSPARENT) just paints a transparent object. i.e. it doesn't erase the circle area of the rectangle.
How to do...?
One option is to set the circle color to say black and then look for an option to replace black with transparent within the bitmap.... but i can't find a solution for this either.
Android :: Widgets - Imageview Doesn't Support Transparency/alpha
Aug 7, 2009When applying an alpha value to an imageview, Eclipse displays the view accurately in layout mode. But when exporting to a target device (such as a phone), the alpha appears to be ignored. This impacts developers trying to create fade ins/outs of elements in a widget. Has anyone else come across this issue yet? Not sure if this behavior is by design or by error.

Android :: Custom View Extending View-Class / Still Based On XML-Layout
Aug 17, 2010I want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?

Android :: Adding View To Bottom Of Layout Inside Scroll View
Mar 10, 2010So my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>

</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my imageview to be at the bottom. However, a child of a ScrollView dont seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?

Oct 8, 2010I have an XML layout with some custom tabs, a heading, and a ProgressBar(main.xml). I wish to add another XML layout(home.xml) to the main.xml layout, as i wish to keep main.xml re-usable for other activity's layouts and simply add things to it as necessary.The problem: after inflating R.layout.home into rootLayout, it seems as though the ProgressBar contained in rootLayout is hidden underneath the content of home.xml.Is there a way to tell certain views(via XML) to float above other views when the layout is constructed in this way?if not, am i forced to use methods such as progressBar.bringToFront() to raise targeted views to the top?what alternatives do i have in z-ordering views when some layouts are constructed using inflation?

Sep 17, 2009I have a problem statement, and here it is: My requirement is: There are a number of images shown on the screen. I want to allow the user to drag and drop any of the images to anyother image. Based on which image is dragged and on which is it dropped, I need to do something specific. So, I need to find a way so that I can get my source view and my target view.To understand this in a better way, consider a practical scenario. In the File Explorer of Windows, we can drag and drop items from the left pane showing the directory tree to any of the folders shown in the right pane.If anyone of you ever faced a similar scenario, please let me know because I could not find a direct support to such a thing (Drag and Drop) in the platform, so may be I need to find an innovative solution to it.
