I want to make a seekbar that has a glowing effect like that. I tried a lot of tricks. I could make it to be glow but not the left side. I tried to cut the left side and put it next to the seekbar but the resolution did not mach and it is an ugly solution anyway.
Can somebody give me some tips if it is possible to create on android

On Android, I have a header with a background image (Random image according to API).
On this header I have texts with some data. My text is every time black but sometimes image is black too. So, we can't see the text.
I'm looking for library or snippet for resolve this problem.
Thanks.
You can use the palatte library for this. Please see the following:

I encoutered this problem months ago and was not really sure how to approach it. First of all you need to use a Layout where you can put View over View for example Relative or Frame. After that you need to make the ImageView thats behind the TextView to be a little bit Lighter or Darker (like a shade) at the place of your TextView so you can choose a color for your text which will always be readable since the shade will be in contrast with the text. What you can do is put something behind the TextView and the ImageView which will be Light or Dark and make the ImageView a little bit transparent using set.alpha(int) if i remember correctly. So at this point you will have transparent image with a light or dark rectangle behind it. It will be visible that the part where you have the rectangle is darker/lighter. Then you put your TextView there with contrast color to the Rectangle and you will always be able to see it. It is kind of complicated, but it will work. Hope it helps.
I think palatte is not available for android. So glide will be a better option. Link
I am developing an Android app and am a bit stuck on how I go about creating the layout I'm after. I said spotify-like (website not app) as I dont want the parallax effect. It's actually closer to http://www.poormet.com/.
What I have tested so far is a RelativeLayout with an ImageView and Listview (with transparent dividers) within it. This layout shows the image in the background between rows which is a step in the right direction. The issue is I'm at a loss as to how to get the images to change smoothly depending on what listrows are on screen.
Also, if I want to replicate the text over the images like poormet example mentioned above, then it seems to me I am going to have to have alternating transparent and not transparent rows.
Am I on the right track or am I approaching this problem the wrong way?
Any guidance will be greatly appreciated!!!
(also, please let me know if what I have described doesn't make sense - more than happy to clarify)
OK, I've read a lot of tutorials and even downloaded some examples, but for the love of Stackoverflow, I can't get my image to stretch like I want it to and I'm hoping that someone can help me out here.
I create an image that is to be the background of a button object in Android. Here is the image:
Now, I'd like for it to stretch to the desire size of the button, whether the button is 50x50dp or 200x100dp. One thing I don't want is the border to stretch as it will look distorted, so I want to specify not to include the border, but stretch everything else to the desired size of the button.
Can someone please show me where the black lines need to go in order to achieve my goal? Do I have to change my original image in order to achieve my goal?
Thank you in advanced.

It's very simple using this tool Android Asset Studio: Simple 9-Path Generator. Although no matter how you do it you will have stretching and distortion due to the textured (non-patterned) background. I would stay away from that style both personally and for usability.
I am trying to make a slideshow like animation to simulate the simple alpha masking in any video editing software, for example i want a chart to go from bottom to top. i tried property animation, animatorset and alphaanimation. searched the web nothing helped :( i was able to control translate / transparency but not both together. another way is to get image frames and swap between them (but i am running from this solution) another solution is to make chart bars on a progress bar and animate them but i had troble with png as prgressbar trims png(i really dont know if this a good solution) any idea?
iam stuck with the creation of a nine patch for a progressbar background.
It has a repeating pattern like a ruler-scala and that given me headache.
here is a image of what i want(at the bottom) and what i have (top).
can someone give me a hint how to acomplish my goal?
edit: or is it generelly possible to do this with a 9patch?
my other attempt was to make a with android:tileMode="repeat" but there i get problems with the height of my image (repeating in the second line), i need something like repeat-x.
Thanks in advance
edit2: ok i managed to do my repeating 9patch by stretching the whole repeating pattern, but its not ideal :(
You seem to be overestimating the power of 9-patches. The most you could do is have a ruler image with expanding space between the ticks. You can't, however, make a 9-patch that automatically tiles parts of your image.
On the other hand, if you create a BitmapDrawable programatically, you can set the tile mode separately for the X and Y axes.
I used to do this in my webview project using border image which provides both options (repeat, stretch, fill).
As webview has kind of it's own problems in android (mostly fixed element) I decided to be more android for the next project and I found out that it's not possible to have the repeated border using 9Patch. It's so awkward as it's needy but not implemented.
In a word android development area makes me crazy, one option here one option there is a usual thing here.
