Android :: Activity Image Background Size?
Sep 12, 2010I am a bit confused on creating an image which will be acting as a background for my activities. So, in short, my aim is that my application should be able to fit the different screen sizes. Therefore, what size in pixel should my three images be to be able to fill the screen of the device in ldpi, mdpi and hdpi?

Oct 12, 2010My goal is to develop a GUI application on top of a background image with buttons in specific places on the image. The first step is to display the background.
The image can be displayed with resources and is described in several FAQs including this one:
how-to-add-background-image-to-activity
It compiles and runs without errors, but the background is black. Here is the main.xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/rootRL" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background">
</RelativeLayout>
The image has been in png, 9.png, and jpg format with basenames of 'main' and 'background'. It builds but does not display. Making clean and recompiling does not help.
This behavior occurs on both the emulator and on hardware -- an Atmel AT91SAM9M10-G45-EK. The SDK version is 2.0.1.
Android :: Start Activity When Main Activity Is Running In Background
Jan 10, 2010I created an application which enables the user to set whether he wants to receive notification while the application runs in background mode. If the notifications are enabled an activity should be started (the dialog should appear on the screen).
I tried to enabled it the following way:
CODE:...........
This is the method from main activity. When onPause() is executed isRunningInBackground is set true.
When I tried to debug it when the main application was running in the background the line
startActivity(intent) had no effect (the activity didn't appear).
Does anyone know how to midify the logic in order to start an activity from the main activity when the main activity is running in the background (after onPause() is called)?
Android :: Click On Image / Pass Image To Another Activity / Page
Oct 12, 2010I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...

View 1 Replies View RelatedAndroid :: Background Image For Wrap_content
Sep 6, 2010I created a custom background image and wanted to use it as the background for a layout that has height of wrap_content. However, the total height of the contents of within that layout are much less than the height of the background image.
When I set it as the background in XML via android:background="@drawable/image", I noticed that it displays the entire height of the image, although the height of the actual contents are much shorter.
Android :: Background Image Placement?
May 6, 2010I'm trying to set my root LinearLayout element (which is set to fill_parent in both dimensions) to have a background image which is always located in the lower left corner of the screen no matter the orientation of the device. It would be excellent if there were some way to set the background image position such as that which you can do with css using "background-position: left bottom;" but I'm not seeing a way to achieve this in Android. Is there a way to do this?

Android :: 2d Background Image On 3d OpenGL Game
Feb 12, 2009I need to draw a background of 320 x 480 (fullscreen) for a OpenGL game. What I did was to stretch the texture to 512 x 512 and mapped it to 320,480 quad and then drew the rest of the game elements. I tried changing the texture image to 256x256 and no noticeable improvement in speed. Game was horribly slow even on the real device. It is actually slower on the device than on the emulator... I think i am the first one to have such a situation.. I am drawing a max of 12 triangles only 2 for background and rest are 64 x 64 textures. on 5 quad made with 10 triangles. I have disabled Depth, Lighting already. Only blending enabled as I use transparent PNG for texture of sprites. render cycle is like this - draw the background - draw the sprites (only 5) [with 10 triangles only] - swapbuffer... Please don't advice me to use 2d canvas, bitmap etc... I need to do it in OpenGL only. don't think OpenGL ES 1.0 is so incapable that it can't give me atleast 25-30 fps with just 12 triangles which you one 256x256 texture and one 64x64 textures (used by 5 quads...
