I am having a little problem. I created a custom background (height of 300px) to use with a layout that has height of "wrap_content."
However, it seems that the total height of the content in the layout is much less than 300px.
But when the custom background is drawn, it shows the entire 300px background, rather than cutting off wherever the content ends.
Other than resizing the background image to a smaller size, is there a workaround this?
Thanks.

Hi all,
I am programming a today plug-in and I need to draw some icons on the screen.
The problem is that when I draw the Icons on the screen, they appear with sharp white edges which does not give the real feel of the icon when viewed on Windows or open in microangelo studio.
Here is a picture, please notice the edges of the icons, note that resco plug-in draws icons with smooth edges. So how can I elimnate this problem??
Query resolution of icons, appropriate use of trasparency on .ico, use of transparent bitblt, whether you need to use png with an alpha trans layer or an artificial smoother on the drawing routine.

Thanks Vijay for the super fast reply,
But I am a begginer in this issue, I see that resco uses png alpha images, but I dont know if I can load png images using LoadImage function.
About Bitblt issue, can you please explain it with a bit more detail?
Thaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaanks alot

If you want to load a png try SHLoadImageFile, it worked when I tested it just now.
Are you drawing the icons this way (bitblt) to stretch them bigger? If not then why not just use DrawIconEx?
Hi,
I use DrawIcon, ofcourse with no stretching, but still some edges of the icons appear as white.
Now, how to create the alpha image??

Many people may be confuse as to what these values mean. I think I've finally figured it out, "Hopefully" lol. It is very similar to how Margin/Border/Padding work in HTML except Margin is both Margin & Border as the border is part of the image.
Please see attached image.
The Red outline is the Edge of the image. Most images have a transparent edge around the outside of the gfx you see. The Yellow outline is the Margin. This is the distance from the edge of the images to the part of the image you don't want stretched when the image gets resized. So, if you have a 2 pixel transparency around the outside plus a 2 pixel Border, than you want a 4-5 pixel Margin. Padding is the same basically except it from where Margin stops of image to the where the Content begins, Content being text or what ever. If no Padding value is given, than the Content will begin at the inside of the Margin. An example would be to add a Left/Right Padding value to the new SoftKey Buttons of the newer builds so the text wouldn't go so close to the edge of the image. Also, same images may have a height or Width Value. This will restrict how big an image can become before it'll add the scroll ability. For example, you don't want the Menu to become too big to fit on-screen. So, you add a Height value, if all Content of the Menu is greater than the height, the menu will add the scroll arrows. It content is less than the height, no scroll arrows are used. With this being said, it could be possible to state a Max Width as well, haven't tested that though.
bookmarked.
Thanks
I want to develop an app that puts a white line grid on a black background.
The grid has 3 columns and 3 rows
There is a 10% border around the grid.
The first column takes up 50% width
The second column takes up 20% width
And the third column takes 10%width
None of the columns expand or contract, they always stay the same size.
Each row is the same height.
If you click any cell, a keyboard appears on the screen allowing you to input data into the cell.
Is it possible to do this white line grid in Android?
If yes, how does one do it?
Best regards

anyone know
Hi All
i have not received any replies.
Can anyone help please
I think it is possible. Do you have a fixed number of rows? is it small? if yes, you could directly use LinearLayout with orientation set to horizontal for each row. There you have android:layout_weight which you can use to play with the different widths you have. For the table borders, just add a View, with a background color of your preference, again use layout_weight if necessary.
If you have too many rows, or you would prefer another approach, you could use TableLayout, and for each row a TableRow, and in the same way use layout_weight for the width. For drawing the borders you could do it in this way: http://www.droidnova.com/display-borders-in-tablelayout,112.html
TableLayout has different parameters like shrinkColumns, or stretchColumns, which you will probably would need, but I am no expert on this, so you would need to play with them.
For displaying a keyboard when the user press on each element of the table, you could have a editText on each, so this would be automatically.
BTW I recommend you asking this type of questions in stackoverflow.com, and tag it with android, there should be more capable people than me to help you with this particular case.
Flash files are used widely, but when people use it, they always need new demand. People always chase perfect. SWF files optimization is one of the chasing things. Here is the tip for how to optimaiz flash swf files.
General optimization
Please use symbols, animated or otherwise, for every element that appears more than once. You need to use tweened animations when you are creating animation sequences, because these animations occupy less file space than keyframs. Use movie clips instead of graphic symbols for animations sequences. You need to reduce the area of change in each keyframe as possible as you can to make the action happen in as small area as possible. Try your best to avoid animating bitmap elements and use bitmap images as background or static elements.
Colors
You can use Color menu in the Symbol Property inspector to create many instances of a single symbol in different colors. Then you need to use Color Mixer to match the color palette of the document to a browser-specific palette. Use gradients sparingly. You need about 50 bytes for filling an area with gradient color. You can use alpha transparency sparingly because it can slow playback.
Texts and fonts
You need limit the number of fonts and font style. Please use embedded fonts sparingly because they can increase file size. Select only the needed characters instead of including the entire font for Embed Fonts options.
Lines and elements
Do your best to group elements. You can separate elements that minimize the number of separate lines that are used to describe shapes by using layers. Reduce the number of special line types as possible as you can, such as dashed, dotted, ragged. Solid lines require less memory and lines that are created with the Pencil tool need less memory than brush strokes.
With these tips, you need not to spend extra money to buy some software or tool. What’s more, these tips are easy to understand, you are not required much flash knowledge.
I am making simple ball game and l have problem.I can't change position of Ball. I tried:
1. SetX() and setY() but lower APIs aren't supported.
2. Params and margins but when I move it left or right, the whole activity content is moving with it. Up and down moving is working fine. (Activity will have 10 ImageViews)
3. Android animations - Problem is that I can't get coorinates (getLeft(), getTop()) during the animation.
4. Canvas and draw elements - I change position of image with onDraw() and invalidate() functions but when I but backgorund and all other images (as bitmaps) it is very slow.
Can you give to me any ideas or suggestions? Thanks in advance.
Can you post the code? What do you exactly want to be done, there can be many different "ball games". You want to change the position of a bitmap or circle on the screen create x and y variables, draw bitmap or circle using them and if they change, the object will be drawn elsewhere
