I'm trying to apply a linear gradient to my ListView.
This is the content of my drawable xml code...
So I apply it to my ListView with:
android:background="@drawable/shape_background_grey"
It works but it looks very "banded" on emulator and on a real device too.
Is there any way to reduce this "behavior"?
Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.Or is it just better to manually write the current finger position to an array?

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?

View 8 Replies View RelatedI'm battling with Android's retarded layout system. I'm trying to get a table to fill the screen (simple right?) but it's ridiculously hard.
I got it to work somehow in XML like this:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent">
<TableRow android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1">
<Button android:text="A" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
<Button android:text="B" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
</TableRow>
<TableRow android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1">
<Button android:text="C" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
<Button android:text="D" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
</TableRow>
However I can not get it to work in Java. I've tried a million combinations of the LayoutParams, but nothing ever works. This is the best result I have which only fills the width of the screen, not the height:
table = new TableLayout(this);
// Java. You suck.
TableLayout.LayoutParams lp = new TableLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT);
table.setLayoutParams(lp); // This line has no effect! WHYYYY?!
table.setStretchAllColumns(true);
for (int r = 0; r < 2; ++r)
{
TableRow row = new TableRow(this);
for (int c = 0; c < 2; ++c)
{
Button btn = new Button(this);
btn.setText("A");
row.addView(btn);
}
table.addView(row);}

I have written an application in android 1.5 to take a snapshot using SurfaceView. The image taken will have pink color fill at center. When we use a default camera application the photos are fine. I know there are some issues in android 1.5, also some hardware issues in some devices, however is there any workaround or settings to overcome this ?

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?
View 3 Replies View RelatedI'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?
View 2 Replies View RelatedIn 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.
View 1 Replies View RelatedI am trying to get those nicely looking android list dividers above and below a TextView. This is how far I am. code...
The ImageView makes what I want - a scaled to fill the parent separator, but this is somewhat not an ideal solution. The android:drawable* in the TextView do not scale to fill the parent - any ideas how to achieve this?
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.
View 1 Replies View RelatedI'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?
View 5 Replies View RelatedI 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.
View 2 Replies View RelatedI 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?
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...

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.
