I encountered this problem when updating my background to use a 9-patch image. The layout is fine on different screens using different sizes of the same image, but when I change the image to be a 9-patch it breaks the entire layout mysteriously.

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?
View 3 Replies View RelatedAs the title says, I cannot get padding around the text.Here's my xml:
<style name="StandardButton" parent="@android:style/Widget.Button">
<item name="android:background">@drawable/nine_patch_3</item>
<item name="android:textColor">@color/white</item>

I have a ListView containing a few different type of items, all having their own background image and font color. In my first implementation I implemented each type of item as its own layout with the background image etc defined in XML (and implemented Adapter.getView() so that it only reuses convertView if it's of the correct type). This works fine but the performance is not that great while scrolling since I'm inflating quite a few Views due to convertView mismatches, so instead I tried using the same layout for all items (to benefit fully from convertView reuse) and changing the background image and font size in runtime. I even keep the three background Drawables I need as members to save time decoding them from a resource for each item, and call View.setBackgroundDrawable() from Adapter.getView(). The problem is, sometimes the 9-patch is not correctly wrapped around the content of the list item when using this approach. While scrolling it usually looks correct but when the scrolling stops, or sometimes when I just tap anywhere on the list, the background 9-patch of some large items starts flickering and is either cropped or resized to its original PNG size rather than stretched to wrap the content.
First of all, I suspect this is a bug? Any ideas why this happens? Could it be that the View is not always measured to reflect the changed content when the 9-patch is applied? I have tried adding an extra call to View.invalidate() but it doesn't solve the problem. Second, does this approach sound reasonable at all, or how should I go about to optimize this scenario?
I believe I have found a graphics bug introduced in the 1.5 platform. I'm looking for some confirmation (or a description of what I'm doing wrong) before reporting it as a real bug.
I have a SurfaceView that fills the screen and on top of that I have a LinearLayout that wraps some other components that overlay the surface. These other components are not visible most of the time, and the LinearLayout has a transparent background so that the SurfaceView is unobstructed until the other components are made visible. Under 1.0 and 1.1 this all worked with a background of #00000000 for the LinearLayout. Now under 1.5 there is a black rectangle obstructing my surface unless I give the LinearLayout background some color. I can still keep the transparency so it is still invisible as it should be but it is strange that it can't be black and invisible anymore. My layout is below. The background of #00000001 works, but changing it to #00000000 results in a black rectangle. code...
I have a background image (full screen) and want to create an exact layout, which fits this background-image. The buttons and labels have to be at an exact place of the background-image. How can I do this? The absolute-layout is deprecated. If I use relative layout, I can use margins, but the positions differ from device to device. The best thing is if I could set the exact positions as percent of the total view size. How can I do this?

I'm setting background color based on a given state of an object in each row in a list. That part is working just fine but when I set the background color on the outermost layout the row no longer highlights when selected. Probably a specific attribute I'm not setting/changing?
View 3 Replies View RelatedI'm new to android but I've been working my way through the tutoials. Still trying to get my head round layouts in a non-html world and was wondering how to achieve the following....
1) I'd like to set a tiled background to fill the screen behind the whole activity
2) I'd like to place a graphic and a button underneath it centred in the middle of the screen.
3) When the user clicks the button I'd like to start a new activity and presumably I have to do something to the current activity so the user can use the back button to get back to it.
seems pretty straightforward.

I have the following linear layout. What I don't understand is if I set the background to another image, the padding information are reset. Is there a way to prevent this?
<LinearLayout android:id="@+id/aPanel"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="@drawable/bkground"
android:paddingLeft="15dp" android:paddingRight="15dp">
<!-- some children here -->
</LinearLayout>
I see the position of the children get shifted when I change the backround drawable of the linearlayout 'aPanel'.
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.
View 4 Replies View RelatedAndroid has a nice way of defining stretchable images called a nine-patch. See these docs for a description of the concept. The idea is to surround a png image with a 1-pixel border where you can define the stretchable areas and the padding dimensions of the image. This is absolutely brilliant and I'd like to use the idea in my iPhone app. Before writing my own nine-patch to UIImage loader I thought I'd see if one already exists. Google doesn't return any results so I don't have much hope, but it doesn't hurt to ask, right?

View 8 Replies View RelatedI wish to customize the button images, but after I opened the png file, changed the color, reimported back into the draw9patch editor, the compiler spew out errors. how can I modify the 9 patch image of the default button?
View 2 Replies View RelatedI'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?
View 2 Replies View RelatedI have some 9-patch images on my app, and they work great on the medium density. When I load the app on a High density emulator/device, these images look grainy. It happens only to 9-patch images. The others look great after the pre- scaling. Is there a way to make them look good after the scaling, like the non-9-patch images?

View 9 Replies View RelatedI'm trying to draw a nine patch onto a Canvas object on the Android. What seems strange is that although I generated my nine patch using the draw9patch tool, the constructor for NinePatch requires an additional byte array called the "chunk" to construct the nine patch.

View 1 Replies View RelatedI'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.
