Android :: Get Dimensions Of ImageView?

Nov 5, 2010

I would like to find the dimensions of an ImageView to use to scale a Bitmap, prior to to calling view.setImageBitmap. ImageView.getWidth and ImageView.getHeight return 0 if no image has been set. (Presumably because the ImageView has not yet been measured?). Is there anyway to determine the dimensions of the ImageView prior to setting the Bitmap?

Android :: Obtaining SurfaceView Dimensions

Jul 6, 2010

I'm trying to develop a little game, with 2D Graphics. I want my "gaming board" to be at a specific position on my screen, so that I can display in-game informations above and below the box. But since there is beginning to be a lot of Android phones out there, I was thinking about getting "dynamic" values so that I can adapt my font size to every device.

My game is not in full screen (but it could be, it's no big deal), but in a window with no title bar.

I'm using an extension of the default SurfaceView class, implementing SurfaceHolder.Callback. I tried writing the following method :


But the values returned are zeroes.

(even if it means changing display strategy) ?

Android :: Wallpaper - Background Dimensions?

Jan 6, 2010

Which are the default dimension of the Home wallpaper/background for the various Android screen configurations (small, normal and large screens with low, medium and high density)?

Are 9-patch PNG files supported for the wallpaper? Should I be using these instead?

I found a method in API level 5 that gives you the minimum size of the wallpaper, but I would like to support previous versions of Android as well.

Android : How To Get Dimensions Of Soft Keyboard?

Jun 18, 2010

My Android app uses a GLSurfaceView so that I can draw to screen directly from native code. As part of the app, I invoke the Android softKeyboard when necessary to receive input. I then feed the input to the native app via JNI. All this works well.. Now, the problem is that I need to know the dimensions of the soft keyboard or any other Input Method windows that are displayed so that I can pan, scroll the native application correctly.

Android :: Correct Way To Specify Dimensions In DIP From Java Code?

Nov 24, 2010

I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment : "android:layout_width="10dip" But all Java interface takes integer as arguments and there is no way to specify dimensions in DIPs. What is the correct way to calculate this? I figured that I have to use property density of DisplayMetrics class but is this a correct way ? May I rely on that formula:
pixels * DisplayMetrics.density = dip

Android :: Scale For Different Screen Resolutions / Dimensions?

Aug 5, 2010

I have a class that extends LinearLayout and handles drawing to the screen. (it is in the early stages) How would I go about determining the dimensions of a screen and resizing the images, etc., that this class is drawing to the screen on the fly before actually drawing them to the screen?

What I'm trying to accomplish is support for devices that have varying screen dimensions and resolutions from the same code base, with each device being scaled properly.

Android :: OpenGL ES Render Textures Of Non Base 2 Dimensions

Sep 18, 2010

Question before I dive deeper into converting my current rendering system to openGL. I heard that textures needed to be in base2 sizes in order to be stored for rendering. Is this true?

My application is very tight on memory, but most of the bitmaps are not a perfect square. Does storing non-base 2 textures waste extra memory?

Android :: Design For Droid Apps Ever-changing Screen Dimensions?

Aug 2, 2010

I'm a web designer by nature, accustomed to changing resolutions and font sizes, but I'm unsure how to design for the Android platform without knowledge of screen sizes, especially when the screen rotates from portrait mode to landscape.

Should I just do generic things that tile, or is there a way to design things of static size?

By this, I mean for the GUI and graphics, not element nodes of the XML.

Android :: ImageView In ListActivity

Jan 11, 2010

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="" 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?

Android :: Text On Top Of A ImageView

Nov 18, 2009

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:


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.

Android :: Nullifying Imageview Src?

Apr 4, 2009

I'm making a little card game in order to learn the more interesting stuff of the UI and I have a question:

I want to show 5 cards on the table, for that i have made 5 imageviews in the xml:


As you might notice here, i'm doing them with an overlap since the uer should be able to pick up the last card and should therefore see it, but the other 4 are just so he'll know what was thrown lastly. my problem is: in the begining the imageviews have no src, but once i give them an image source

using CODE:..............

I dont know how i can undo it - i can't set the imageResourceId to null since it is an int type so is there something like -1 or some constant value that means null? i know about visibility, i'd rather not use it here unless i really have to, since it'll require a bunch or refactoring that i prefer to avoid...
