Android :: Way To Create Nine Patch Png Image In Phone?
Oct 8, 2010
I have an image with a fixed size , ex. 300 x 300 ; it was a background image of my view. But my view size was dynamic , so i need an image which can stretch , according to desired size. can any one tell me how to make it ? I know we have to use nine oatch drawable ? i don't know how to tool given with android sdk ? can any one tell me how to make image to png?
I want to set a specific background image for all my buttons. So, I changed my PNG file into a Ninepatch drawable using the "draw9patch" tool(by specifying the line of strecth).Then, I applied this as background to my button using "myBtn.setBackgroundResource(R.drawable.new_png);" Now, the background appears for the button, but the lines of stretch are also visible on the android screen, wherever I'd specified them in the tool. Can you help? Is there something wrong in how I'm using the tool?
I'm trying to create on of these images, but Eclipse won't accept it once I've used the draw9patch tool. I've found other people having the same problem, and saw this comment: I discovered later that the problem I was having was caused by the image not being exactly true to the nine-patch spec as defined in the documentation. Once I fixed the image to have a clean (i.e., no gradients etc) one pixel border it was fine. "'m not much good when it comes to image design. What does this mean, how do I create my original png file to meet the specification for Nine Patch?
I am trying to use a nine patch image as a background in an android game. The image expands well in multiple resolutions but, my game has slowed down by 10 fps. I used to get a consistent 45 to 50 fps now I get 35 fps. The question is when we use a nine patch as a drawable and set it as a background in a view does it have any performance implications as opposed to a plain bitmap drawing.
i have list views with image views and text views etc in them, and i'm trying to fix up a situation where the background image of a list element changes in the "pressed" state. if there's a straightforward way of doing that, please let me know! right now, i override onTouchEvent() in the topmost view, and also in those child views who don't just delegate to their parents which would be image views. i have to check for long clicks myself, but basically this scheme works. the list views are potentially different sizes depending on how much text is in the views etc, so i thought i would use a 9-patch as the background. however, when the background changes from flat white to the 9-patch, this seems to indent the view a bit - ie give it margins. eh? if i change the image to a non-9-patch, the margins remain as they are. i've tried different sizes of 9-patch, from 320x150 or so down to 100x30 etc, no change. what's going on?
I'd like to use a 1x1 size Nine-patch image from Android drawable resources. When I'm trying to display it with <ImageView> in my layout xml file, this one is never showing up on the Android emulator device. Here's the xml code below. Code...
I'm wondering if there is something like 9-patch in Android, but for web development? Disclosure: I have no idea about web development at all, but I was curious to know if it exists. And a simple web search with the term 9-patch didn't bring up any related results, so I figured it has either another term or it doesn't exist or is not used widely enough.
I have an image in .png format in "drawable" folder and need to create Bitmap from it, so can use in public void drawBitmap (Bitmap<http://developer.android.com/reference/android/graphics/Bitmap.html>bitmap, float left, float top, Paint <http://developer.android.com/reference/android/graphics/Paint.html>paint)
I have been trying to create a ListView Activity with an ImageView in every row. I've used this tutorial: http://developer.android.com/resources/samples/ApiDemos/src/com/examp... The issue is that there are always some dividers missing whenever I run the example. The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.

I have 10" MID tablets and I was messing around with the root files on 1 of them to try and get the 2nd camera to work but I messed it up and now I need to re install the operating system.
How can I create an exact image of the 2nd tablets installation so I can just boot from the image file on the broken tablet?I have searched all over and can't seem to find out how to do this. I have not even been able to see the hidden files on my PC. I tried android commander and similar programs but none of them recognized my device.
I have a screen where I need to put a background image. I need to display only a part of the background image in each screen . Now when the user swipes towards left , the next screen will be displayed taking another portion of the background image. This transition from the first to second screen should give a 3 Dimension effect of moving the screen. I am unable to get any help form Android forums.

I've got thumbnails which larger side is 70px (e.g 70x40 or 52x70).
I need to create a gray box 70x70px and put the thumbnail in it, so that image is aligned with the box at top vertically and center horizontally.
How to do that?
I've tried with an ImageView 70x70px, gray background, but image is not positioned as it should (it's in vertical and horizontal center, instead of vertical top and horizontal center).
I've also tried wrapping it with LinearLayout 70x70px, gray background and then positioning it, but then i get 1 or 2px line between LinearLayout and ImageView. I tried to set padding and margins to 0, but the gray line stays on...
So I returned to stock, but when I rooted the guide I used didn't suggest I save my stock recovery flash. Now I need to return my droid (cracked screen) and I'd prefer there not to be any any problems with the warranty. So is there a way to get my recovery back to stock?
I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.
I try to implement a hover effect (effect when button is pressed) through putting a semi transparent PNG file on top of the button background and the button icon. Unfortunatly the button background file is a 9-PATCH-PNG which causes some trouble here: It "swallows" everything on top of its layer and doesn't allow to cover the stretchable areas (the fine light line around) of the nine-patch-png. In other words, the black lines the top and left edge of the 9 PATCH PNG cause not only stretching, but also padding behavior.
