Animated Layout Mask?
Nov 4, 2013
I want to have a couple of layouts and have one of them animate to reveal the layout below. I've attached a crude image of what I'm attempting to do.
As the top layout animates out of the way, I want all of its contents to remain in their relative positions. The same goes for the layout behind.
I have tried setting one of the layout's height to 0 and then animated it to be full height, but this reeks havoc on the scaling and the placement of the elements inside. I also tried implementing the solution in the link below, but it didn't do what I needed.

Is there any way to fully mask browser ID (on default or other browser). On my "other" device, I could ID either the stock browser or Opera as IE and access non-mobile versions of sites that have sniffers.I do not see the same options on Android. I can disable mobile view but it will not get by some sites that still force mobile versions.

I have a single-channel PNG file I'd like to use as an alpha mask for Porter-Duff drawing operations.If I load it without any options, the resulting Bitmap has an RGB_565 config, i.e. treated as grayscale.If I set the preferred config to ALPHA_8, it loads it as a grayscale ARGB_8888 instead.How can I convince Android to treat this file as an alpha mask instead of a grayscale image?
mask1 = BitmapFactory.decodeStream(pngStream);
// mask1.getConfig() is now RGB_565
BitmapFactory.Options maskOpts = new BitmapFactory.Options();
maskOpts.inPreferredConfig = Bitmap.Config.ALPHA_8;
mask2 = BitmapFactory.decodeStream(pngStream, null, maskOpts);
// mask2.getConfig() is now ARGB_8888 (the alpha channel is fully opaque)

Is there a way I can specify an input mask to the EditText control in Android?
I want be able to specify something like ### - ## - #### for a Social Security Number. This will cause any invalid input to be rejected automatically (example, I type alphabetical characters instead of numeric digits).
I realize that I can add an OnKeyListener and manually check for validity. But this is tedious and I will have to handle various edge cases.

Can you guys share how can we mask password input in fullscreen virtual keypad. EditText setPinEditText= new EditText(context); setPinEditText.setImeOptions(EditorInfo.IME_ACTION_UNSPECIFIED);)
I tried using setPinEditText.setTransformationMethod(new PasswordTransformationMethod());
Masking the password input in portrait vkp mode works fine with this change but when I rotate to landscape mode, in fullscreen virtual keyboard mode it doenst worked.

Is there a way to draw a circular gradient mask on a bitmap in Android? Trying to produce something similar to a foggy window. Click the window and a transparent circle shows up revealing whats behind the window. Prefferably using a gradient so the center of the circle is completely transparent and the further out from the center the less transparent. Is this possible?

I found something that has helped my X photos to have more clarity. But before I write this, this is *not* spam to promote a product. It's just something I wanted to share because I've been a little disappointed with my X photos (as can be seen in some of my prior posts), and there may be others who feel the same way.
After reading the "Droid X vs. Droid Incredible 8MP Camera Showdown" thread comparing photos between the 2 phones, and seeing the sharpness of the Incredible camera over the X (even though the colors of the X appear to be more accurate), I wondered if there was a way to improve the photos taken with my X.
I did a search on the internet and found this free, almost professional-grade photo editing software: GIMP - Wikipedia, the free encyclopedia. So I downloaded it to see how well it worked.
I found that using the "sharpen" feature actually produced a certain harshness to the photos, and the size of the photos were reduced when saving them. After enlarging both the originals and the "sharpened" photos to 100% to compare them, I could see why. The Sharpen filter seems to reduce the overall quality and pixels of the photos, thus producing a harshness.
However, I read on the Wiki site about using the "Unsharp Mask" to accomplish the same thing without the degradation that the Sharpen filter produces. And sure enough, not only were my photos sharper with the "Unsharp Mask," but they did not have that harshness produced by the Sharpen filter. And after enlarging the before-and-after photos to 100%, I could see that the quality of the full-size view had not been reduced in the process as it had with the Sharpen filter. And when saving the edited photos they are approximately the same size as the originals (indicating that some of the photo information hadn't just been "removed" while filtering the picture).
That said, there are settings to the Unsharp Mask that need to be considered. I have changed the "amount" setting from .25 to 1.0 depending on the photo in order to make sure I'm sharpening the photo as much as possible without overdoing it and producing a similar harshness that results from too much alteration. You must be careful to look at the entire photo, and even to enlarge the before-and-after to 100% if needed, to get the proper balance on a per-photo basis.
The photos still aren't quite as sharp as the Incredible's after editing (the optics must simply be better on that camera in that regard). But this near-professional quality software can really make photos stand out with more clarity and it retains the accuracy of the color content of the Droid X camera. It also offers a large selection of interesting filters to do other things with your pictures.
Note: If anyone decides to try this out, be aware that this software attempts to install other programs, but it allows you to decline them. You must decline about 2-3 other programs during the process of installation. I also had to uninstall the Yahoo toolbar afterwards. I guess that's how they can offer it for free.
I apologize if this post is inappropriate -- please feel free to remove it if it causes any offense. I am just really glad that I can tweak my X photos so that they have greater clarity than the X software (including Vignette) produces.

While developing for Android, I am unable to open more than one main.xml file in an Eclipse editor at a time.Each time I open one, it simply replaces the editor (tab) of the first main.xml with the new one, instead of opening a new tab - even if the contents of the existing tab were unsaved.Even stranger, I can open multiple main.xml files from different projects with no problems.This only happens when they're within the same project.

I am using eclipse 3.5 with the ADT plugin.when I view layout xml files, i get two tabs in the view the source code view and a graphical view.the graphical view almost never works for any of my layouts.it usually shows "NullPointerException: null" at the top and nothing else. when it does work, it often does not match what i get in the simulator or device.it seems like this thing simply is not ready for prime time; although the idea is very cool.has anyone else had much success with it?

I am trying to make a map overlay animated much like MyLocationOverlay does. Currently the only things that I can see to make animated are Views but Overlays don't extend View functionality. My next thought was to try to lodge a View into the overlay, but the redundancy makes it seem like this solution is incorrect. I grabbed the android source hoping that I could just look at MyLocationOverlay source and that would let me know how the animation was supposed to be done, but I can't find the source for anything involving maps. If that is available somewhere it would help. Can someone point me to the MyLocationOverlay source or let me know what the paradigm is supposed to look like for animating map overlays?

I've successfully created a countdown kitchen timer activity, however my goal is to have an activity that has 3 timers on it that all work independently. I created a separate layout just for the timer itself and moved the timer code into a class and I've used layoutinflater to create the views and then added them into the linear layout for the activity. I get the layouts fine, however there's no functionality. There doesn't seem to be anything that ties the class code to the activity. How should I approach this? Can anyone point me to some working example code?

I have 5 layout folders. layout, layout-small, layout-normal, layout-medium and layout-large.
My app is heavily image based. As a result I have created the proper images. mdpi, hdpi and xhdpi. I don't think I need to worry about ldpi since screens are only getting bigger.
With this in mind and the need for me to now create a good landscape layout for all my pages, how do I go about this? Is it simple layout-land? No need for large/small/normal again right?
Considering that I've got all my hdpi and xdpi images do I even need layout-medium, layout-large and layout-normal? Because the images will be adjusting themselves based on screensize surely I can use one layout and have that work for all screens..?
It's all getting very confusing now that I'm trying to add a landscape view to my app. It doesn't do it very well at the moment so I will probably have to design a landscape friendly layout so I can understand that I would need to rebuild all my layouts for this particular use (We're talking about 100 layous here but oh well, I can manage it. )

I didn't ask whether it also had the clock.Is this one that comes with Sense or is it one I should download for her somewhere? Is there more than one of these out there?I have a Droid and I see that Beautiful has a nice weather widget, but I can't tell if it is animated.
