Android :: Measure Widgets Before Display?
Nov 10, 2009
I need to find out how wide a button with particular text will be before displaying a layout. Is this a valid way of doing it behind the scenes?I have other UI components that have to all be the same width in my layout, as whatever this one button is (the other widgets are placed all over the UI and I can't use any other layout methods to force them to be the same size).So I thought I could create this temporary layout, add my fake button, measure it to get its width, then use that value on all other controls. Right now I'm doing the same thing only in onWindowFocus(), but this happens after the layout has been displayed once, which I'd like to avoid.

I am trying to display images dynamically on a home screen widget. As RemoveViews offer a very limited set of methods to interact with the layout, I'm trying to use HTML to get the same effect.

I have a custom view i am writing for my drawing app but the first time i set the drawing into it i need to get the dimension for the view (using getMeasuredWidth() & getMeasuredHeight()). But until the view display these return 0. I have tried calling: requestLayout() invalidate() numDraw.measure(MeasureSpec.EXACTLY, MeasureSpec.EXACTLY); but nothing seems to force the values to update.I guess the question i am asking is : does anyone have any tips on how to get view to update its measurements off screen?

Just back from a very nice vacation in Iceland, and await the data roaming bill from my phone company. I hope for the best having limited my traffic as much as possible, but I want to know in advance. I used the very nice app NetCounter but it didn't measure roaming data traffic at all.So I want to build my own app measuring just roaming data traffic. I have a few booleans to start with ( NetworkInfo.IsRoaming() & TelephonyManager. isNetworkRoaming() ), but I'm not sure how to measure the traffic if true.So the question is: How do I measure data traffic while roaming? (Something like API level 8 TrafficStats functionality is what I'm after, but for API level 3). The used SmartPhone is Samsung Galaxy i7500 (Android 1.6)

I would like to make an app that measures little time intervals (nanoseconds) so I need to know about time resolution and precision regarding such measures with an Android device.
In other words:
- Is it feasible to get reliable values of the current time with nanosecond resolution?
- If so, is feasible to measure such little time interavals? I mean, is there any way to tell the app/OS to focus on measuring the time interval specified in the current thread instead of allowing other processes to make the measuring task not precise?
I've tried to measure the time between the execution of two different lines in code but the results are not always the same, somehow random, then I suppose Dalvik and its process management is causing this to be unreliable and random. What I need to do is to measure distances by getting transmission and reception of audio tones of 16-20 KHz (done in [1] with iOS), thus needing resolution and precision.

Any app that measures the battery's mAh? I have tried battery monitor by 3c, but I don't think it works completely with HTC phones. Either it keeps saying measurement requires 40% or larger charging cycle or it reports something crazy..

I'm using the FontFitTextView that was posted in this other thread, but it isn't working exactly right for me. The measureText() call is returning a number that is obviously too small to display the string. When it runs through to find a font size that will allow the text to fit, the font size it settles on is still too big. I feel like there is some other kind of padding or margin or some other invisible that is contributing the math that makes up the width which is causing the discrepancy.For example I want to set the text of my FontFitTextView to be "10,000.25".The width of my FontFitTextView is 96 pixels, with 8px padding on both sides, so my available width is 80 pixels. The call to measureText() says that the text "10,000.25" is 64 pixels wide. This means that the current font size should be small enough to display the entire string. However, when the string is actually drawn on the TextView the last 2 characters are chopped off and all I see is "10,000." instead of "10,000.25"

I would like to get access to the area covered by a finger for each touch event on an Android.Every touch event will result in a coordinate pair X and Y independent of how big the finger and consequently the touch area is that triggered the event.

I want to develop a game, so I need to know elapsed time at lots places in my game. For example, to measuring FPS. I see there is some example use "System.currentTimeMillis" to measure elapsed time. But I see the warning on document: http://developer.android.com/intl/zh-TW/reference/java/lang/System.ht... "This method shouldn't be used for measuring timeouts or other elapsed time measurements, as changing the system time can affect the results." So, if this method should not be used for measuring elapsed time, then what will be suitable?

I'm new to Android application development and I'm currently experimenting with various UI ideas. In the image below, you can see a vertically scrolling list of horizontally scrolling galleries (and also textviews as you can see). I'm also doing some matrix and camera transformations which I will come to in a minute.
For the background of the list elements, I use green. Blue is the background of the galleries, and red is the background for the images. These are just for my benefit of learning.
The galleries being used are extended classes where I overrode the drawChild method to perform a canvas scale operation in order for the image closest to the center (width) to be larger than the others. The list view going vertically, I overrode the drawChild method and used the camera rotations from lack of depth dimension in the canvas functionality. The items in the list are scaled down and rotated relative to their position's proximity to the center (height).............
