I need to know exactly how big the screen is on the device in real units of length so I can calculate the acceleration due to gravity in pixels per millisecond. Is there a method somewhere in the Android API for this?

Is there any way to determine the layout of a physical keyboard (ex: QWERTY vs QWERTZ)(if there is one)? I would like to map commands to keyboard keys if there is a hardware keyboard available, but the layout is very important. I have had users from Germany complaining that layout is not optimized for their phones (since the Y and Z keys are swapped). Is there any way to automatically detect this, or am I stuck making it a setting?

View 4 Replies View RelatedThe application I'm working on is a service which runs in the background. The problem is that I need to determine the height of the notification bar for some functionality of the service.
I found a number of solutions for this, for regular activities - a view inside an activity can determine its own height without the notification bar, based on for example checking its actual view size from its onSizeChanged event, after it is already drawn. However, this is not applicable to a service which has no physical view drawn, nor directly related applications.
I would really appreciate any ideas on getting the size of the notification bar! Perhaps at a system level API?
I am trying to determine the physical size of a screen in inches.
Normally, I could do something like this:
CODE:.............
Then use metrics.widthPixels and metrics.heightPixels. Now that I know the width and height in pixels, I should be able to calculate size in inches if I know the density. Easy enough, metrics.xdpi and metrics.ydpi.
Then screen dimension in inches should be:
CODE:.................
Seems simple enough except that it doesn't work.
On a Motorola Droid, the system reports back: xdpi and ydpi as 96 (which cannot be true).
And the screen resolution as: 480 x 854. Which results in a width of 5" x 8.9" -- which as I'm holding this in my hand right now, I must say - cannot be correct. how to accurately calculate this?

CODE:..............
How can I get the body (second EditText) to fill the rest of the screen, but still have the scrollview kick in when the contents of the body are too long? Like a height="wrap_content" and minHeight="fill_parent"
layout_height="fill_parent" seems to not do anything if you put them in a scrollview
A working example of what I want is the email app compose window
I tried this and the EditText elements act like they are wrap_content and no filling is happening. Just scrolling if you type enough

I am planning to have a Service send a broadcast which a BroadcastReceiver will act on and I would like it to create a Notification if an application is not currently on screen, but if the application is on screen (ie. showing to the user) then I would like to offer a Dialog and not create the Notification.Is it possible to determine if an Activity or application is currently on screen?
View 5 Replies View RelatedI want to put a button next to a EditText and I want their heights to match.For example, from the built in Android browser:
The Go button is the same height as the EditText field.I know I could wrap both these views in a parent layout view, and set both of their heights to fill_parent, and that would make them match.However, I would like to do this without having to give the layout a static size.I would rather have the EditText take whatever height it needs based on the font size and then have the button next to it match whatever height that might be.Is this possible with an xml layout?
I am using two ListView in a screen. I want to divide the height of each ListView but I want it to be screen independent. For this I need to know the Height of the screen. I am using xml to do this.

I have to create a bitmap (which is zoomable) and I just want to get a rough idea what the tallest height should be. getResources().getDisplayMetrics().heightPixels; does the above return the height, in portrait mode only? I'm not binding my UI to this absolute value, it's just a rough fit.

View 2 Replies View RelatedI am having problem with a GridView within a RelativeLayout, which is again within a ScrollView. The problem is that the height of the RelativeLayout is not following the height of the contents of the GridView. When there are more than one rows, the GridView is clipped and a scrollbar appears, which is undesirable. I have tried to illustrate my problem using an screenshot from the Android hierarchy viewer. You can see how the red RelativeLayout box has clipped the second row of the GridView. I am pasting the XML layout of the page (page.xml) and the individual grid item (griditem.xml). I have used the following code to inflate the grid items in the gridAdapter code:

I'm having trouble with this layout - I need a ScrollView, then a LinearLayout with a button below that:
CODE:........
The scrollview pushes the linear layout under it off the screen. The only way I can get this to work is if I explicitly set the scrollview height in pixels to be less than the total height of the screen, but hardcoding a height isn't going to work on different devices. How can I do this?

I am writing an android application that has 3 views one below the other. Each view has to be of equal height, depending on the screen size. Each view occupies the full width of the screen. How do you specify in the layout xml that the view has to take up 1/3rd height of the device display height? What would be the appropriate layout to use in this case?

Im just curious about this. Ive been around the Incredible forums a lot and hear sometimes about the newer VZN keyboard smartphone coming out in the future. I was pretty stoked about this new big HTC phone but realized it had a keyboard and I immediately got turned off. I dunno about you guys but I NEVER got into the physical keyboards and really prefer the touch version 10 fold.

When I specify font size for a TextView in points, like this:

I get different physical size of text on these two devices. On 245 DPI, the text is barely readable.
Now, "pt" size is supposed to be physical. I.e., in my test, both text blocks should have letters of the same physical height. Which is not the case.
