I am trying to place only the exact amount of data into a TextView but I need to know how much it can hold. Is there a way to do this based on it's height, width and the textsize?

How can I determine the number of visible characters that a TextView can display. For example if I change the orientation this number may change. If I change the resolution then also the number of visible characters changes.

I have a TextView in a RelativeLayout which contains an integer number. The number will range between 1 and 99 - can anyone tell me how to size the TextView so that its width is always the width of the string "99" even if it only contains "1"?
I need this because the positions of the components to the right of this TextView depend on its width, so all are position depending on how many digits the TextView contains.
I don't mind if this is done in XML or code - I just want to avoid having to set the width of a TextView in pixels!
I am trying to create an activity layout that has a top level vertical linear layout like so:
CODE:................
This works ok as long as the wordDefinition text isn't very long. But, when I set the text to something very long, it pushes the back button off the bottom of the screen. Why? Isn't the ScrollView supposed to scroll the text in the child TextView?
I've tried playing with weights (e.g., giving the top text view a weight of .2, the scroll view a weight of .7 and the button a weight of .1, but to no avail.
I have a layout that looks something like this:
[TextView 1] [TextView 2]
[ TextView 2 spill-over ]
Essentially, I need the contents of TextView 2 to wrap to the next line, but start where TextView 1 starts. I was thinking that if I knew how much text would fit into TextView 2 before it runs out of space on line one, I could take the rest of the text and put it in another TextView below the first two. So I need to measure how much text will fit into a TextView (which can be tricky because as far as I can tell, Android will try to break the text in a TextView at a good location so that it won't break a word in the middle if it can be avoided) or I need a new idea on how to lay this out.
I have a TextView with an OnTouchListener. What I want is the character index the user is pointing to when I get the MotionEvent. Is there any way to get to the underlying font metrics of the TextView?

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.

Well this is really a two question thread, I'm new to Android.
1) Which multi-protocol (AIM, Facebook, MSN, etc) client eats the least amount of battery?
I downloaded Meebo and it seems pretty good (heard eBuddy is worse in consumption), I'm wondering if there's anything better.
2) Does GTalk consume the least amount of battery since it's integrated with Android in comparison to third party clients?
As of now I don't have any friends who use GTalk but I'm trying to convince a few to get it.
The database of my application need to be filled with a lot of data, so during onCreate(), it's not only some create table sql instructions, there is a lot of inserts. The solution I chose is to store all this instructions in a sql file located in res/raw and which
is loaded with Resources.openRawResource(id).
It works well but I face to encoding issue, I have some accentuated caharacters in the sql file which appears bad in my application. This
my code to do this : Code...
The solution I found to avoid this is to load the sql instructions from a huge static final string instead of a file, and all accentuated characters appears well.
But Isn't there a more elegant way to load sql instructions than a big static final String attribute with all sql instructions?
I have some doubt about the amount of RAM in my Android device . Not sure if it has 256 MB or 512 MB . I was able to run through a terminal in android : cat / proc / meminfo
Apparently I have approximately 466MB of RAM. If so will I have 512 MB. The question comes because if I run the command "free" or if I see from the above command in LowTotal line, only tells me 233 MB ...
What is the correct information in RAM for my device? I did the same procedure to another cell which mine where I'm more sure of having 512 MB of memory and this is what I get: URL>...The funny thing is that it shows me 584 MB of MemTotal and the same amount for LowTotal. It seems my device, the first , is not using the total amount of RAM available.
I have a TextView that I created in the main.xml. In my app.java I am dynamically positioning that TextView based on where the user taps the screen.

I don't want to publish a service, or use the file system. I really want a pipe that can write data from one end and read it from the other end. I can handle the case where the starter Activity dies while the "startee" activity is trying to read from the pipe.

I have 2 email accounts that I check on my Samsung Captivate, and I'm having problems with both of them. When I click the Email icon and view both of these accounts, one account shows -1/1 messages and the other shows -1/25 messages. If I get on Yahoo and Gmail and check they show the correct amount. Yahoo has showed this for a few days, and Gmail just started today.Can anyone tell me what is wrong and why they show a negative amount of messages?
View 1 Replies View RelatedSo, it definitely blows that this was advertised with 1 gb of ROM, and we only ended up with about 370mb of ROM. But, it is what it is. Now, I know RAM is more important when it comes to making the phone snappy and dealing with all the open apps. But, does it affect the phones performance when the phone gets low on ROM? I'm around 220mb of available ROM, which is still a good amount, but I cant help but check the file size of every app and game i download and cringe if its bigger than average. So, is there a number I should try to stay above? 150mb, 100, 50, or does it really not matter as far as the phone's responsiveness and snappiness is concerned?

I am writing a application that needs to draw a "route" comprised of lots of GPS points (long+lat). The points are close together and don't follow roads, simply drawing a line between each point is ideal.
The current implementation I have is very slow as I am looping over all the GPS coordinates and creating a new Point and overlayitem in an itemized overlay. This takes around 20 seconds for it to load all of these points and draw them to the mapview. Is there a way in which I can construct a series of lines or point from the GPS coordinates and draw them onto the mapview?

View 2 Replies View RelatedI have decided to go to a smartphone on 13th June when my present contract expires. My Query is, I am in the U.K. and if I look at contracts for the iphone they normally include unlimited Wifi and 1Gb of wireless data, whereas the Desire seems to come with only 500Mb of wireless.
I would much prefer to get a Desire, but I am concerned that I could be lumbering myself with excess charges if I go over the 500Mb limit.
I have never had a phone with an Internet connection before so I'm sure that there will be a lot of playing going on at least to start with.
