Android :: PNG 24 With Gradient / Not Showing Correctly

Jun 5, 2009

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?

Android :: Alpha Gradient On Bitmap Of PNG

Dec 11, 2009

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?

Android :: Smooth Gradient On Different Devices

Jul 26, 2010

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.

Android :: Gradient Image Is Displayed Incorrectly

Sep 21, 2009

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.

Android :: Gradient Banding On High DPI Devices

Nov 2, 2009

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?

Android :: Gradient Drawn On Canvas Looks Banded / What To Fix

Sep 23, 2010

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.

Android :: How To Add Padding To Gradient <shape> In Phone

Oct 25, 2009

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?

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...

Android :: Color Banding - Png Resource That Has Gradient Fade-out Alpha

Oct 29, 2010

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 ?

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:

Android :: Accessing Battery Info Activity (or Any System General Activity)

Jan 20, 2009

I want to be able to show the Battery Info activity in my app, which shows things such as the exact level, battery health, etc.I'm not sure how I can get it, though a few applications such as Power Manager, Any Cut, etc. show this screen as well. I found in the source code of Settings this intent in a file called testing_settings.xml,But I don't know how to use it. I would guess from the fact that Any Cut has a list of activities, that a list of said activities exists somewhere, and therefore an easy way to access them exists, but I haven't found it.

Android :: Force Activity In Landscape Mode Without Activity Restart

Aug 21, 2009

I have a problem to start/create Activity in landscape mode. My Activity need to start in landscape mode and be used in landscape mode by users. So far, I used setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) to force screen orientation of my Activity to landscape mode in onCreate() method.

In addition to this screen mode requirement, my application need to start another background thread in onResume() method, and this thread takes some seconds in order to finish an initialization process, and it is not desirable to to stop/restart this thread's service during the initialization process.

However setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) forces my Activity restart in a very little while (means onCreate->onResume->onPause->onStop are executed twice at the first place). As a result, my background thread be stopped/restarted during the initialization process, and this makes me a mess at this moment.

Android :: Passing Arguments From Loading Activity To Main Activity

May 16, 2010

I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing.For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits.I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this?
