I have the following layout defined: code...
now i want to get the height of the RelativeLayout (i want to specify the height of its children programatically) code...
but the size returned is 0. How do I get the size of the RelativeLayout (it's mostly pseudocode above, but both layout have a height/width of "fill_parent" in the xml)

How do I change the size of the controls placed in a layout? (by any method) I tried to change the height of an EditBox ->setHeight(10); doesn't seem to work.
View 4 Replies View RelatedI am trying to make a widget to show on the home screen(s). My problem is lets say I set my icon to 30x30 when I load the widget on the screen the Icon is the correct size but the layout itself takes up a lot more space than what is actually needed. This means that I can't really place my widget next to other icons on the screen. Its like the bounding box is 3 times bigger than the content that fills it.
Here is my XML
[CODE]
I have tried wrap_content and other width/height settings but nothing seems to reduce the "Box" around my widget content. I clicked on my ATK widget and started to drag it around on my HTC Aria and it shows the bounding box around the widget and that one is the same size of the content inside same with all the other widgets on my screens.
I want to place three button on the bottom of screen. I place these button in a linear layout and sets its gravity bottom. Currently these button wrap according to their labels so have different widths. But I want these button equi size. Means all three button should have same width (without using fixed widths).
View 5 Replies View RelatedI am trying to develop an app for which I want multiple screen support. I have read the Android article on Best practices for Multiple Screen Support. As per the article we have to follow 3 important things:
1. Mention support for different screen sizes (large, medium and small) and any density in AndroidManifest.xml.
2. Place images of 3 dpi's (120, 160, 240) in 3 folders res/ldpi, res/ mdpi and res/hdpi.
3. In layout's the dimension should be mentioned in "dip" units. Then Android will take care of the scaling on its own.
I have implemented all these points in my project. The images are picked up correctly from the appropriate folders. But the arrangements of the controls in not same. e.g. I ran the app on three emulators 1. Resolution 240*320 dpi 120. 2. Resolution 240*320 dpi 160. 3. Resolution 240*320 dpi 240. (All the emulator have same resolution but different density). The problem is the position of the controls is not same on all the three emulator. As per my understanding if the android:layout_marginLeft and android:layout_marginTop are mentioned in "dip" then this problem should not occur. As the density of the emulator increases the controls get placed more towards the right. Is it necessary that I provide layouts for all combinations of dimensions and density i.e. in layout-small, layout-large, layout- medium, layout-long,layout-notlong?
Every time that I want to do a Layout, I'm getting a black layout preview then I can drop stuff on it, that's ok, but how can I change the size of that blank surface (xml). The question came because I set a folder layout-large and then when I add a new layout.xml to that folder it came with the same size, as a layout-normal.

View 1 Replies View RelatedI have a layout which specifies sizes of widgets in relative dimension, for example:
CODE:..............
Immediately after onCreate, I want to know how much is the height of the ImageView. How to do that?
If I call getHeight() in onCreate, I get 0.
I have also tried imageView.postDelayed, it works on 2.1 emulator but fails on 1.5 emulator (I got 0, too).
Finally, I tried to create a Handler, and then I call handler.postDelayed with 10 ms delay. It works in both 2.1 and 1.5 emulator, but failed when I start the program in eclipse debugger (So, I conclude that using the delay doesn't guarantee that the getting of the height happens after the imageview is layout-ted.)
This is my first post. I've had a Moto Droid since day one, and I just love it. It is without a doubt better than any phone that I've had over the years, and that includes the iPhone, BB, etc.
However, there are 2 things that I don't understand - Font size and a spell checker. It is imposiible to read the small font size in emails or text messages.
1. Why has there not been an app to either change the font size or be able to zoom in? Picasy has incorporated multi-touch for zooming, so I've to assume that its doable! Why not have the same in an email client.
2. Why is there not an email client out there that allows for spell checking? There are many such apps for the BB! I am a terrible speller.
I am not complaining, I just want to understand the limitations from a developers prospective, as I am sure these isuues will eventually be addressed.
So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
View 1 Replies View RelatedI am currently developing a dictionary application with voice database. I would like to know about the current Android limitation on the file size. I am using a self-provided sqlite database ( > 50mb ) . I tested that once the built .apk size exceeds ~30mb the app will not be installed onto the simulator (INSTALL_FAILED_ INSUFFICIENT _STORAGE). Could anyone confirm me that if up until now there is no way to embed such large size files in a single apk ( Aimed to sell at Google Market without requiring user to download datafile afterwards). Also, is there a limitation of 1,048,576 bytes for a single file in the assets folder ?

I manage a cache of bitmap. Do you have an advise to fix the maximum size of it?
View 2 Replies View RelatedCan somebody explain to me what makes up the installed application size? I have an apk that is about 8 MB, and often when I install I get the INSUFFICIENT_STORAGE error. I have around 25-30 MB free space on the phone. I'm doing debugging so I have to upload lots of new versions. If I uninstall the previous version then I can install the new version. The application manager claims that the app is taking up 22 MB. So back to the original question, how come the app is taking up 22 MB when it really only is 8 MB?

I kept getting OutOfMemoryErrors (if anyone could explain this too, that'd be great!) and so I took a look at the sizes of the images saved to the sd card, and they seem to be roughly double what they are on the server. Why is this, and how can I make them smaller?

While developing for Android, I am unable to open more than one main.xml file in an Eclipse editor at a time.Each time I open one, it simply replaces the editor (tab) of the first main.xml with the new one, instead of opening a new tab - even if the contents of the existing tab were unsaved.Even stranger, I can open multiple main.xml files from different projects with no problems.This only happens when they're within the same project.

Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.

I am using eclipse 3.5 with the ADT plugin.when I view layout xml files, i get two tabs in the view the source code view and a graphical view.the graphical view almost never works for any of my layouts.it usually shows "NullPointerException: null" at the top and nothing else. when it does work, it often does not match what i get in the simulator or device.it seems like this thing simply is not ready for prime time; although the idea is very cool.has anyone else had much success with it?

I've successfully created a countdown kitchen timer activity, however my goal is to have an activity that has 3 timers on it that all work independently. I created a separate layout just for the timer itself and moved the timer code into a class and I've used layoutinflater to create the views and then added them into the linear layout for the activity. I get the layouts fine, however there's no functionality. There doesn't seem to be anything that ties the class code to the activity. How should I approach this? Can anyone point me to some working example code?

View 1 Replies View RelatedI am programming an app using an absolute layout (@ eclipse). How to fit the button size with the screen size? (I have four buttons per row).
View 1 Replies View RelatedImagine I have a toolbar implemented as a horizontal LinearLayout as follows:
[___Button1____] [___Button2___] [___Button3___] [___Button4___]
When someone clicks on Button2, I want the toolbar to change to:
[___Button1____] [___________Button2___________] [___Button3___]
The toolbar should transition from the first state to the second state through a smooth animation. I would like to use a scale animation on Button2, and while that is happening, Button3 and Button 4 should move to the right (while the animation is going on). At the end of the animation (or maybe during), I will fade Button4 out.
Question: How do I achieve an animation of the layout of the toolbar such that only one component (i.e. Button2) is being scaled while the others are not being scaled - the layout is simply updated during the animation of Button2.
I looked at LayoutAnimationController, but it does not appear to allow me to either:
1. specify different animations for the different components, OR
2. indicate that only animate one component and don't animate the others.
I can't scale the entire toolbar because that distorts Button1/3/4 which I don't want.
