9 Patch png not working correctly for background
android, nine-patch
Solution
OK, I tinkered with your 9 patch. I must say it was poorly designed (72 dpi, while it should really be 320 dpi).
So, I redesigned it (you can see I moved the black pixels) and saved it to 320 dpi (in the drawable-xhdpi folder).
It seems it scaled well at ldpi and mdpi screens (so, I guess it will also scale well at hdpi):
The patch I used is this:
Problem
I'm trying to create a background image for my app that will look sharp on all resolutions/orientations. I'm new to android development, but I understand the easiest way to achieve this is to use 9 patch images. I thought I understood how they worked, but I can't get it to work. I've created a background image @ 768 x 1280 which is the resolution of my Nexus 4. When I don't 9 patch it and view it on my device, it looks fine (obviously, because the resolution/orientation matches the device's): So it looks nice and sharp. But then I add the patches onto the image using the `drawer9patch.bat` file and rename the file to '.9.png' and this is the result: Knackered! The strange thing is: in the preview pane in the right hand side of the draw9patch tool it all looks fine.... I've also tried making the image at a smaller resolution, but the logo & text don't look sharp; they look pixelated... I feel there must be some vital piece of the puzzle I'm missing? The area I've defined as content is being stretched? Here is my layout code: ``` <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/my_background_image_patched" android:padding="0px"> <!-- Login controls here ---> </RelativeLayout> ``` Here is my 9 patch image (which is located to the 'drawable' folder):
