I have created the following progressbar style and set the corner radius to both shapes (background, and pogress). But it seems that when I animate / set progress below 90 my progressbar current progress shows rectangle shaped borders, without any radius. I would like to know if it is possible to have the corner radius all the time, even if the progress is 30 or less than 90,95. Can anyone explain why this is not working?
Also I need this to work with the API LEVEL 8
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Define the background properties like color etc -->
<item android:id="#android:id/background">
<shape>
<corners android:radius="25dp" />
<solid android:color="#00000000"></solid>
</shape>
</item>
<!-- Define the progress properties like start color, end color etc -->
<item android:id="#android:id/progress">
<clip>
<shape>
<corners android:radius="25dp" />
<gradient
android:startColor="#fff"
android:centerColor="#fff"
android:centerY="1.0"
android:endColor="#0d1522"
android:angle="270"
/>
</shape>
</clip>
</item>
</layer-list>
Update: I've added the right code that explains my problem
Ok. After researching and doing some more tries to accomplish this I only got to the solution of using a 9patched PNG file to make this work.
It is definately possible to have corner radius all the time. I did it by adding this line before setcontentview method of your custom progress bar.
customProgressDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
This will make your whole view transparent. So fill the boundary inside your corners with some color.

I was given a design for a custom ProgressBar that looks like this:
The way it works is that the bar is completely blue at 0 progress, and as progress is incremented, each side fills in equally white toward the center until the entire bar is white at max progress.
I've got the bar set up just fine. I'm using two ProgressBar objects, one that moves left-to-right, and the other rotated so that it moves right-to-left.
The part I'm stuck at is how to draw those extra circle shapes that move toward the center along with the white progress <clip>. I tried just adding an extra <shape> to my <clip> item in the XML, but that stretched the circle out as if it was using the circles to fill in the bar.
Is there a way I can add these extra shapes to the ProgressBar XML itself, or do I need to create another drawable for these shapes and then update their position manually in code? I'm not sure what the correct approach is here and I haven't been able to find any similar examples in my research. Any help is appreciated!
Here's the XML I'm using for the progressDrawable:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#android:id/background">
<shape>
<corners
android:topLeftRadius="12dp"
android:bottomLeftRadius="12dp"/>
<solid android:color="#29A4DD"/>
</shape>
</item>
<item android:id="#android:id/progress">
<clip>
<shape>
<corners
android:topLeftRadius="12dp"
android:bottomLeftRadius="12dp"
android:topRightRadius="0dp"
android:bottomRightRadius="0dp"/>
<solid android:color="#F05926"/>
</shape>
</clip>
</item>
</layer-list>
I'm trying to create an button with xml gradient code. (Because I'm a new user can't upload the image :( ) This image has two colors and corners in its edges.The color which starts the gradient will start from 15% of all gradient length and ending color ends on 75% of gradient length.
I use this code to create Gradient with two colors:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item >
<shape android:shape="rectangle">
<gradient
android:angle="-45"
android:startColor="#64bcfb"
android:endColor="#2f8fd4"
android:type="linear"/>
<corners android:radius="10dp" />
</shape>
</item>
</layer-list>
The problem is that i don't know how to add the start percentage and the end percentage of gradient.I have some searches about this and ind some things in:
banded background with two colors?
Gradients and shadows on buttons
in both there is some solutions but i it's not work for me. The solutions is about creating a simple bar with two colors but i want to create a button that have some corners in its edges also.
I cant also use the original image in my app because i need to changes its colors pragmatically.
Have any body some idea about how we can add percentages in gradients?
This is quite old but no answer and I think I was having the issue and found a fix.
If you only need a gradient with 2 colors, a single transition and with corners, you can do the following:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp" />
<gradient
android:angle="270"
android:startColor="#android:color/transparent"
android:centerColor="#android:color/transparent"
android:centerY="0.65"
android:endColor="#color/colorPrimary"
android:type="linear" />
</shape>
The trick here is adding a centerColor and centerY and modifying it's center. This will allow you to modify where the transition occur.
i'd like to use a seekbar to show the current value and adjust the desired value. I managed to change the desired value via thumb (Progress) and the current value with the bar (SecondaryProgress). There is only one little bug/problem:
When SecondaryProgress becomes lower than Progress, the bar shows the same value as Progress, even the value of SecondaryProgress really becomes lower or even 0 (checked that in debugger).
What it should look like:
SecondaryProgress < Progress <-- doesnt work, shows:
(==== O ) (=======O )
SecondaryProgress == Progress <-- works
(=======O )
SecondaryProgress > Progress <-- works
(=======O== )
Is there a setting that enables me to adjust that? Or do I have to customize the seekbar? And if so, where should i start? For me this doesnt look like a thing i can do in Layout...
Thanks for your help
Might be a bit late, but the best solution I found to that problem is to customize the seekBar, and to use a secondary progress drawable that would use only a part of the height of the seekBar.
Let's say, for instance, that we want to use the bottom of the draw for the secondary progress, and keep 10dip at the top of it for progress. We could use the code below as progress drawable for our seekBar :
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ffffffff"
android:centerColor="#ffdddddd"
android:centerY="0.50"
android:endColor="#ffffffff"
android:angle="270" />
</shape>
</item>
<item android:id="#android:id/progress">
<clip>
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ff0088eb"
android:endColor="#ff0068e7"
android:angle="90" />
</shape>
</clip>
</item>
<item android:id="#android:id/secondaryProgress">
<clip>
<inset
android:insetTop="10dp">
<shape>
<corners android:bottomLeftRadius="5dip"
android:bottomRightRadius="5dip" />
<gradient
android:startColor="#ff00c8fb"
android:endColor="#ff00a8f7"
android:angle="90" />
</shape>
</inset>
</clip>
</item>
</layer-list>
The main tip is to put the secondary progress drawable after progress drawable in the layer list, so that it is drawn above it, and is always visible, and to use an inset so that it doesn't take the whole SeekBar height.
In your example, you could get a result like this :
SecondaryProgress < Progress
(====---O )
SecondaryProgress == Progress
(=======O )
SecondaryProgress > Progress
(=======O-- )
I want to make seekbar like this: http://img687.imageshack.us/img687/2371/volumec.png
The thing is, that Ive already found customizing seekbars over here http://groups.google.com/group/android-developers/browse_thread/thread/be3fed0b4f766cc?pli=1
but the problem is, that I need **those gaps** between in my drawable and I dont know how to manage that.
Would you be so kind some of you, I`ll appreciate it very much.
Thanks in advance, wishing all the best!
this is my resources style.xml file that is applied to seekbar:
<item name="android:indeterminateOnly">false</item>
<item name="android:progressDrawable">#drawable/seekbarcolors</item>
<item name="android:indeterminateDrawable">#drawable/seekbarcolors</item>
<item name="android:minHeight">20dip</item>
<item name="android:maxHeight">20dip</item>
<item name="android:thumbOffset">8px</item>
<item name="android:focusable">true</item>
and here is my #drawable/seekbarcolors:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<solid android:color="#ff0000" />
</shape>
</item>
<item android:id="#android:id/secondaryProgress">
<clip>
<shape>
<solid android:color="#00ff00" />
</shape>
</clip>
</item>
<item android:id="#android:id/progress">
<clip>
<shape>
<solid android:color="#0000ff" />
</shape>
</clip>
</item>
A Seekbar is a pretty powerful widget. Ddo you want the user to be able to "seek" the volume here? It's not made to show progress with gaps.
What you need here (if you don't need to grab and seek the volume) is lots simpler. Create a single ImageView to the right of "Volume" in your sample pic. In your progress-watching AsyncTask, put code in onProgressUpdate() to change the shown image across 10 images - each the same as the last but with one more bar - as progress breaks each 10%. You can write code to put a single image times properly positioned across a space, but that is harder and buys you little.
The thing is that i need to seek volume..as you can see, i' ve styled seekbar with my custom shape where colors are set
Last thing i need to do is create repeatable shape with block of opacity 1 and block with opacity 0. How this can be done? I am new to android developmemt therefore not very smart with shapes :) thanks

I'm trying to make a custom list divider. It has one horizontal line that's a subtle gradient, and a second horizontal white line immediately below it as a sort of "drop shadow".
I'm trying to use <layer-list> to accomplish what I want, but it's not working out the way I expect.
Here's the code:
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:startColor="#ccd0d3"
android:centerColor="#b6babd"
android:endColor="#ccd0d3"
android:height="1px"
android:angle="0" />
</shape>
</item>
<item android:top="2px">
<shape
android:color="#android:color/white"
android:height="1px" />
</item>
</layer-list>
If I use android:divider to assign this to a ListView and set the android:dividerHeight="2", I get a grey gradient that's two pixels high. The white line is nowhere to be seen.
If I set the white line's android:top="1px", I see a one pixel grey gradient and a one pixel black line below it.
Any ideas what I'm doing wrong?
You should set dividerHeight to 3 or avoid setting it altogether.
