Android :: ImageView With Graphic From The Www?
Feb 27, 2010
I want to show a graphic inside my activity. A graphic thats from the www. Just like http://www.google.de/logos/olympics10-sskating-hp.png.
Wenn, in general I would download the graphic, convert it (maybe with photoshop or something), rename it (if neccassary) and copy it to my drawable folder. Then I can use its id inside my xml layout.
Now I want this procedure dynamically.
Which is the quickest way to do so?
I dont want to use WebView for this...

I do not consider my G1 to be a phone. My old second hand Nokia 6100 was a better phone because it was so small and light weight. Why I bought the G1 is because I consider my G1 to be a Mini Laptop. But we need better program for it. I need a graphic program like the Paint Shop Pro 4 where I can resize and fix photos. I still have not figured out how to connect to WiFi and call the USA for free (I am in Vietnam) BUT G Voice should be doing something in a few weeks. I will wait for them. Tonight I downloaded the USB connection program so my G1 can make my computer in my hotel connect to internet but edge network here is expensive. I did find a way to stop the phone from Sniffing the EDGE network. I mess up the name in the APN code by adding xxx to the end. Then it will not connect to DATA.

There is first an ImageView (the light) and then two textViews. All of this inside a TableLayout. (source here: http://code.google.com/p/switchctrl/source/browse/trunk/android/res/layout/device_switch.xml)
I want to have a rotating animation of a loading indicator Ontop of this light when this particular device (light) performs an action or an action is performed on it.
How do I put an animation ontop of this light imageview?

I'm writing a game for a computer class that I'm currently taking for school. The game has a lot of graphics associated with it (mostly in .png format). There is too much data to simply include it as part of the 'res'. The way i'm currently doing it, is to store all of the graphics in a single zip file, in a folder on the SDCard, e.g., / sdcard/Game/PlayerImages.zip (or whatever). And then i'm using the ZipInputStream to read from those, then using the BitmapFactory to decode the stream and then draw them on the canvas. The problem that I'm having is that this method is terribly slow if I add a lot of images into the zip file. The best way I have found thus far is to name the .png files within the zip numerically, then use a for-loop to jump directly to a specific file, but this is still a very slow way of doing it. I would like to use a single file (like zip) to hold all of the files for several reasons. 1., i'm trying to use a file container so i can simply update graphic 4.png and then push it into the zip file (for example) from a server. 2., because android sees all image files on the sdcard when you open the gallery application. 3., easier to prevent data manipulation by doing an md5/sha-1 checksum on 1 zip file, rather than every time a file is opened if it weren't in a container.

I would like to create a user interface which would contain network indication icons (3G, WiFi...) and I would like to use existing graphic elements which are displayed in notification bar.
Does anyone know how to get these existing elements and use it in custom layout?
I guess these icons are all ImageView elements and I am wondering whether it is possible to retrieve them with findViewById() method...

I trying to create an application similar to the notepad3 tutorial. The main difference is that I need to be able to create different "note formats". Is possible to obtain an xml file from the web and use it in the creation of an android interface? I have researched about the Metawidget library that is a very useful tool for android but I haven't been able to create interfaces dynamically.

I have a graphic in Adobe Illustrator (lets say a cat) that I want to use in an Android application. I would like to have the user be able to change the color of the fur using a color picker. What can I save the graphic as (SVG?) to allow me to programatically control the color from with the android app? Do I have to have a separate image for each color of the cat?

Sorry to disturbing you, but everybody got a message from Android Market about the changes. It says: A "feature" graphic, landscape aspect ratio, 1024 x 500 (required). What is a feature graphic? I googled it but didn't find any example.

I tracked the behaviour of the different screen sizes when I increased the position of a graphic by 10 pixel. Unfortunately happened what I already thought. When the display is bigger, I'm able move a graphic a lot of times more to get to the bottom of the screen. So the ratio between the graphic and its environment is not correct anymore (so not 10 pixel as on normal screen) although the change of the graphic on the different screens looks correct (On big screen it is bigger, on small screens it is smaller). When I move the graphic from the top of the screen to the bottom, I can move that on 480x800 about 65 times, on 480x854 70 times, and on the 320x480 screen only about 25 times. So the target must be to calculate the right ratio so that 10 pixels on the small screen are 17 pixel (or sth. similar) on big screens. What approaches do I have to do that? I already thought about getting the value of res.getConfiguration().screenLayout to know if I have a small, normal, or big size to be able to calculate anyhow the right ratio, but this both seems to be pretty cumbersome and moreover I get values from res.getConfiguration().screenLayout I can't explain. I launched 6 emulator instances and got the following values from res.getConfiguration().screenLayout:
240x320 QVGA low density: 17 320x480 HVGA medium density: 18 480x854 WVGA high density: 34 480x800 WVGA high density: 34 240x400 WQVGA low density: 34 240x432 WQVGA low density: 266435490 (yes, I really get this value!)
This approach seems to be useless because I cannot even distinguish between 480x854 and 480x800, much less of the last value which seems to be corrupt.
How can I solve it to move a graphic on the different screens with the right ratio? How do game developers solve this when they support all screens?

I know the specs for the EVO show it does 1xRTT, but I am not seeing a graphic icon showing when the phone is in this mode. I travel quite a bit and with my Hero I know areas where I would be switched over to 1XRTT, but now the EVO still only ever shows 3G. Can anyone verify if there is a dedicated icon for 1XRTT or has HTC rolled everything under the 3G icon?

I have a rooted orange hero to mcr2.3 On the lockscreen, is there a way of disabling the graphic which goes across the screen? The graphic contains the time and the word orange etc. I would like an arty picture on my lockscreen but the time graphic spoils it. Catch my drift?

I have an ListActivity that I wan't to add a logo to at the top above the list but I'm unsuccessful. This is what my layout looks like at the moment.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/logo" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false"> </ListView> <TextView android:id="@+id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/list_empty" /> </LinearLayout>
Then I add an drawable to the ImageView logo in onCreate. I've managed to show either the ListView or the ImageView but never both of them in the same LinearLayout. Is it possible to add other views together with a ListView?

I'm using Android 1.6.
I'm wondering if there's a simple way to put text on top of an ImageView element. Specifically, I'd like to have text overlayed on top of a rectangle filled with a color gradient.
I have the following in my XML layout:
CODE:................
But the text specified in android:text doesn't show up in my view.
Any thoughts on how to overlay text on top of an image?
There might be a simpler way to do this, so I'm open to alternative suggestions but I haven't been able to find anything via the google.
