Android :: Gradient Styles - Not Working On The Outer-most LinearLayout
Aug 10, 2010
In my Android application I've hidden the default title bar, introduced a TabView and added my own titlebar under that TabView's tabs. At the moment, I'm using the ?android:attr/windowTitleStyle style which makes my new titlebar look gray and gradient. It looks pretty good, but my screens are looking pretty grayscale. I'd like to spice things up a bit by making this titlebar a different color gradient.
What am I looking at here? Creating my own image and using it? The ?android:attr/windowTitleStyle style seems to expand depending on the height of your custom titlebar; so I'm not sure it's actually a single image.
I've attempted to throw a LinearLayout over it with a bit of translucency (ex: making the color #800000FF), but the gradient style I have behind this LinearLayout disappears.
Update:
Per my answer down below, I've figured out that I can create an XML file that defines a gradient and use that. It works fine inside a LinearLayout (titlebar_gradient) I have on my layout. However, it is not working on the outer-most LinearLayout (background_gradient). Could someone tell me why? As I understand it, the ListView should be transparent...

When I tried to create a ViewFlipper inside a class which extends LinearLayout, its throwing an exception
"java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()".
I am creating the ViewFlipper using,
ViewFlipper flipper = new ViewFlipper(ctContext);
But when I create the ViewFlipper in a class which extends Activity, its working normally. What may the reason?

If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg

I have a RelativeLayout that has two LinearLayouts in it. One is a bunch of TextViews and EditTexts that make up a form and the other is a ButtonBar that submits the form.
anyways, everything looks great in portrait, but when i switch to landscape mode the bottom TextView/EditText element is being hidden by the buttonbar.
screenshot to show the problem. as you can see some of the "email" textview and all of the email edit text are being hidden by button bar.

I have the following custom view:
This I have achieved by using the Canvas' drawArc() method. However, with this drawArc() method I cannot limit the arc's inner radius.
What I'd like to have is something like this: where there is only an outer ring left.
What I need is an drawArc() function where I can set the inner radius of the arc. Anyone an idea how to do that?
Overpainting the inner area doesn't work, because it needs to be transparent. Painting an inner circle with Color.TRANSPARENT after painting the red and blue cones doesn't remove the old color. It just puts another layer on top, which is transparent and through which I can still see the red and blue.

In the midst of this crappy day, I dropped my Hero and cracked the outer screen. Where can I buy a new casing to replace the one I just broke? I've searched around but have found virtually no places that sell a basic faceplate.

I m doing some task with following code,
I want to access inner class variable from outer class method.
class Outer extends Activity
{private Handler mHandler = new Handler();
StopTheThread()
{mHandler.removeCallbacks(mUpdateTimeTask);//
This is the what I want to do:
} class Inner
{ final Runnable mUpdateTask = new = new Runnable() {
public void run() {
//Some Code Goes Here
} };
InnerClassMethod()
{ mHandler.removeCallbacks(mUpdateTimeTask);//
This statement working fine here. Here mUpdateTask is inner class variable which is not accessible from outer class.

I have a LinearLayout and I am setting a Background image. I am using a PNG24, and the image has a gradient in it. When I see the image on the computer the gradient is perfect, but when I see it on the emulator or on a real phone, some colors are lost and I see only like 10 colors, so I see lines and not a perfect gradient. Is the emulator 'compressing' the images? Should I make them in other format?

I'm trying to apply an Alpha gradient to a bitmap that I've created from a PNG. I want the image to be opaque at the top and fade to transparent at the bottom. I know this can be done be using getPixels and setPixels for Bitmap and iterating through each row of pixels in the Bitmap and setting the alpha values accordingly, but i was hoping there was a slightly neater way of doing this. I have been looking at the LinearGradient Class and using a Porter Duff transfer mode, but i don't seem to be having much luck with this. It seems that my source image is lost when i apply the Shader to the drawable. Anyone have any tips on how i might apply an alpha gradient to a bitmap?

In my app i have gradient as drawable which i am using as background and i want it to make it look as smooth as possible. After googling and trying by myself i came up with the following. On nexus one if you call only setDither(true) your gradient is still banding so you have to set PixelFormat like this Window.setFormat(PixelFormat.RGBA_8888). But on the other side G1 does not support RGBA_8888 so calling it make the gradient even uglier than before so Window.setFormat(PixelFormat.RGBA_8888) will not work well on devices that don't support it.What is the correct way smooth my gradient on all devices on which my app will run.

I have got another mysterious issue. So, I am setting a background image for LinearLayout. This image contains gradient. Don't know why, but after I launch application the image appears to consist of several parts that actually form "smooth transition" of gradient, and that's why it seems that background image is not a gradient.

I've been looking at some issues with the background of our application, particularly on high-density devices (240 dpi, 480x854). I managed to eliminate banding on existing devices (i.e. G1/G2, 160 dpi) by applying the android:dither="true" attribute to our nine-patch image, which is a 1x480px PNG with no noise added. Looks great. However, if I use the same image on a higher resolution device, the banding is pretty nasty looking. Same happens regardless of whether I use a shape+gradient, a noisy nine-patch PNG, or an android:dithered nine-patch PNG -- even if I create an 854px-tall image. Is the use of gradients going to become a problem on high screen density devices, purely because of the display colour depth, or is there any way to solve this?

I have a gray gradient drawable (png image in res/drawable). If I draw it on a white Canvas it looks banded (not smooth). If I put the gradient on white background in GIMP, and then draw this drawable on the Canvas, it looks great. What's the problem? I tested this on Nexus One. Calling setDither(true) on the drawable has no noticable effect.

I have a shape with a gradient that I'm using as a divider between ListView items. I've defined it as follows:
<?xml version="1.0" encoding="UTF-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#ccd0d3"
android:centerColor="#b6babd"
android:endColor="#ccd0d3"
android:height="1px"
android:angle="0" />
</shape>
I would like to add 6 pixels of padding on either side of the gradient, so that it doesn't extend from edge to edge of the screen.
However, no matter where I put an android:left="6px" and android:right="6px", it doesn't seem to take effect. I can put it in the <shape> element, the <gradient> element, or in a separate <padding> child of <shape>, and it doesn't change anything.
How can I add padding on the left and right of my list divider?

Seems my original post ("ugly pngs...") somehow disappeared :( nvm.
I have a problem with a png resource that has gradient fade-out alpha.
The png looks great in the emulator, but displays an artefact known as "color banding" (http://en.wikipedia.org/wiki/Colour_banding)
Has anyone surpassed this issue ?
My designer wants to trop a shadow behind his icons, and that's where the bands appear.
What are my options ?

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?

For Style and Thems defination, CSS is considered to be a better standard...(as it has seen many revisions and widely used already in the web areas).. Any reason, why Android using XML approach as opposed to CSS.. Are there any plans of support of CSS too in future..

I want to enable different themes in my app. Some elements need "special" variations, like, for example, a headline TextView. Lets say for the example, in theme A, I want the headline yellow on black, in theme B red on white, while the default TextView uses black on white and vice versa.
Now, I can style the default TextView pretty easy by using <item name="android:textViewStyle"> with a different TextView style in each Theme style.
For example:
CODE:............
But how can I do it with the headline? As far as I know, I can use style="..." in the layout XML. But there, I can only use an item style like "headlineForBlack", which would ignore the current theme, while I'd rather need something like "style 'headline' for the current theme".

I am creating a button programmatically. It is rounded and has a gradient background, and works fine and looks nice, but I couldn't do two things I wanted:
Set a 1 pixel stroke with a given color. I tried getPaint().setStroke(), but couldn't figure how to set the stroke color. How should I do it?
Align the gradient to the bottom of the button, no matter what height it has. Is this possible?
For reference, this is the code I'm using:

Where can I find default styles for my widgets? Let me give you an example. In the Contacts application, when adding a new contact, at the very bottom there are two buttons that have a particular background. I have traced that to here: http://android.git.kernel.org/?p=platform/packages/apps/Contacts.git;... and it would seem that that background is achieved by using style="@android:style/ButtonBar" on a LinearLayout. From what I understand, this is a system-wide theme default for button bars. However, what I am searching for is not a ButtonBar, but similar, so I tried searching for this ButtonBar in the documentation, hoping to find other similar styles I could use. I *thought* I would find it in R.style:[url]
