is there a way to set the weight of a view using API calls? I construct parts of my UI at runtime. The dynamic UI has multiple View. However, I want to set the weight of those view to be non-equal. Any idea on how to do that?

LinearLayout obeys weight and as per documentation weight gives priority to an object. Here is the layout I have: Here you can see that the first textview has a weight of 2, second has a weight of 0, but still the second text view takes up all the space. If I give the first edit view a weight of 0 and second a weight of 2, surprisingly, first edit view gets more space. Isn't this weird, or am I doing something very wrong. I am poor in layouts. <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent"

This is my first attempt to write applications on a mobile platform but i hope that my experience in programming will help.I have in mind the "Better, Faster, Lighter Java" book, but will this be "the" answer to my question? Are there any tips specific for the Android Platform that will allow me to build lightweight applications?
View 2 Replies View RelatedI have a simple horizontal linear_layout with bunch of image views in it. the trick is that the views have different widths, relative to the size of their parent (the linear layout). I set the layout's weightSum to a 100 and the layout_weight to let's say 10 of one view and 15 of the other, on so on. And it did not work. I also tired using float values setting the weightSum to 1.0 and the layout_weight of the image views to 0.2 and 0.3 and so on. But it didn't work either. I did search this group for any references to the weightSum but found nothing. Any ideas how to handle it?

View 3 Replies View RelatedI have played around a bit with the xml files for creating layouts and can't explain the behaviour of layout_weight when using it in a LinearLayout that has orientation="vertical"
When creating a layout that is horizontal everything follows the documentation, that a child would get more space if it's has the highest value.
But the following code for vertical orientation, give more space to the item with lowest weight.
CODE:..........
And the question is: Is this a bug or just a feature that maybe need more documentation?
For those people who have held the device, how is the weight distribution? Just from the looks of it, it looks like it would be a tad top heavy because of the hump.

Or maybe there is another constraint that I do not understand.
View 2 Replies View RelatedIn Android I am writing an application in which, I would like to capture an event if in case user doesn't do any activity (tapping/key press). For better context - It is like session timeout.
Basic solution - I can override the key press/tapping event and put one timer which continuously run either as thread or service. In my opinion this is bit heavier solution in terms of resource.
According to documentaion, FILL_PARENT basically lets the view take up the entire extra space. Weight also dictates how much of the extra space can be taken by the view. What is the difference? For eg: What happens when I use, new LinearLayout.Layout Params(Layout Params.WRAP_CONTENT,LayoutParams.WRAP_CONTENT, 1.0f)
View 1 Replies View RelatedI currently have the Samsung Galaxy (I7500). I have it for a year+ now. A couple of months ago I wanted to buy the Desire, but I decided its too early for an upgrade (big mistake). It's very hard for me to keep waiting for the perfect device since I hate my galaxy so much. So my question is which phone would you recommend?
IPhone 4 no way ofcourse, Samsung Galaxy S no way cause Samsung really screwed things up with the original galaxy (and it has no Flash), which leaves me with HTC Desire HD or Desire Z. The DHD has an extremely weak battery, and I want my next phone to last a day (moderate user). So, is the Desire Z worth the money? The things that bother me with the Desire Z are:
1. Weight - It weigh 180 grams! Thats sick, way too much. (the Desire is about 135, which isn't light, but not heavy either)
2. Battery life - I'm not sure how long does it last under moderate usage.
3. Size - its quite big, and its especially because of the keyboard, which I don't really need / care about.So, Whats your opinion?
I always read about this funny weight value in the Android documentations. Now I want to try it for the first time but it isn't working at all. As I understand it from the documentations this layout: should create two buttons that are horizontally aligned and share the space equally. The problem is the two buttons don't grow to fill the space. The result is something like this: I would like the buttons to grow and fill the whole line. If both buttons are set to fill parent only the first button is shown and fills the whole line.

View 18 Replies View RelatedI would like to know whether its possible to record call in Android. If its possible then which class should be used for that purpose. I think there should be some message broadcast receiver invoked when a call is accepted and application should be started in background and record the conversation. Would like to know if this is actually possible and it it is then what classes to refer to?
One more thing if I want to send the recorded file to a server through GPRS then is there any limit in size for it to get transfer through GPRS? Small files will be transferred easily through GPRS but what about larger files? Is there any upper limit as to files of this much size can be transferred.
More importantly I want to know about the call recording function. Whether its available in Android phones as a native applicatoins or not? If its not available then can a application be written that can record all incoming and if possible outgoing calls as well.
Is there a blacklist app that allows me to simply reject (either by picking up and hanging up, or by saying the number is disconnected) numbers that I specify. I used an app called iblacklist on my iphone and it works wonders for this. I was wondering if there is something in the market that functions the same as this. iblacklist also removes the calls from the recent calls list, that would be useful but not very important.

Also when it comes to data synchronization between server and our app , how is that generally implemented?
