Android :: Set The Widgets Width To Fill_parent?
Apr 29, 2009
Ive read the docu for home screen widgets but i couldn't find a possiblity to set the widgets width to fill_parent, instead i must use dip. The widget should fill the screen width regardless of the screen orientation. Somebody have a idea?
It is posssible to set a animation to a home screen widget? Something like,if special button of the widget is clicked, the widget shows a view that breaks out of the widgets borders which are defined in the home screen widget meta-data file?

Consider a VideoView added to a Linear Layout with parameteres FILL_PARENT, FILL_PARENT.
The Linear Layout gets added to the root layout which is a Relative Layout, with parameters WRAP_CONTENT, WRAP_CONTENT.
Which parameters take precedence here?

I'm sure I am missing something simple...
Background:
I am new to android and UI design, and I just wanted to play around with layouts. Right now I want to stack a checkbox on top of text label. I am using the following xml layout which works fine:
CODE:................
My Tests (just to get a feel for how things works):
Scenario 1) When I set the CheckBox's layout_height to "fill_parent", the CheckBox takes up the whole screen and is aligned center (i.e. - the TextView disappears).
Scenario 2) If I instead set the TextView's layout_height to "fill_parent", the CheckBox does NOT disappear. In fact, nothing disappears, and the layout looks the same as the above xml where everything is pushed to the top-left.
The Question (and comments): How come Scenario 1 works the way it works?
This behavior seems inconsistent to me. I thought that fill_parent is only supposed to let the element fill up whatever space is available in the parent. So to me, it seems that the TextView should get whatever space it needs (since it is wrap_content), but the CheckBox should take up the rest of the space (so the TextView would be forced to the bottom of the screen, but not invisible). In other words... Scenario 2 makes sense to me, but scenario 1 does not.

I am using a HorizontalScrollView to contain and scroll 3 child widgets, each of which is either an ImageView or a custom widget. What I'd like to achieve is something like homescreen, where each child widget filling up the whole width of the display and the user is able to switch to the other widget by flickering horizontally. I am having a hard time figuring out what properties I should assign to each of the child widget in order to have them fill the parent container. I get it working if I hard coded the width for each child but I'd like them to be able to fit to any screen resolutions, as the current Android homescreen does.
Here is the xml (pseudo like)
HorizontalView -> LinearLayout -> children widgets

The Android Developer guidance on Creating a Custom Dialog specifies a layout that starts:
code:........
If I use this code I get a dialog that sits in the centre of the screen with about 40 pixels of the underlying view visible on each side.
What exactly does "fill_parent" mean (for the width and height)?

I want my dialog box to fill the screen as I have seekbars set on fill parent, and so it makes this tiny dialog in the middle of the screen with tiny seekbars to go along with it.

I have a Gallery with a set of images that was downloaded at run time.I followed the example here:http://www.anddev.org/a_androidwidgetgallery_-_example-t332.html but instead of using i.setImageResource(this.myImageIds[position]);I used i.setImageBitmap(bitmaps.get(position));This doesn't fill the entire width of the screen, only as much as the width specified here:i.setLayoutParams(new Gallery.LayoutParams(150, 150)); When I increase this number, the item scales with it instead of showing more images per the example. I've even tried to scale the images before adding them to the set. Not sure what I'm missing, or where other examples of this might be. Any help would be great.

I am having this issue where I am trying to have a single TextView span one to two lines, fill the cell completely (so you can also click edges of the cell and it will trigger) and center-align.
This is the layout for the cell:
CODE:...
However cells seems to be filled correctly ONLY if it happens to wrap around and end up spanning two lines of text. It shows center-aligned and you can click anywhere in the cell to trigger the click. The cells that do not span multiple lines of text are left-aligned and trigger (highlight) only if you click where the text is. There is a "numb" area which does not react to clicks inside the cell if the text is short.

I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution.
To start, here is my row item layout:
CODE:..........
The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height.
Here is a portion of the getView() method:
CODE:.........
The rest of the method simply sets the appropriate text and images for the row.
Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context);
Am I missing something essential? Or does fill_parent just not work with dynamic heights?

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)

If I have the following:
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
CODE:...................

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).............

Is there any style I can set which will make a set of buttons the same width (without specifying an explicit size in pixels)? For example:<Layout> <Button> <EditText> <Button> </Layout>..is there a way to make the two buttons the same width, even though they may have different text? Right now I'm measuring the larger one via a measure call and setting the other one to that explicit width,

I do not know the difference between these two attributes and for the height also. Take a TextView for example, what would happen if I set its layout_width to wrap_content and set its width to 50 dip?

I think the answer to this question is probably so simple, but I'm struggling....
I have a TableLayout with multiple columns. I want the last column to be of a fixed width, but I want to define that width to just be able to hold the widest possible string from my program. i.e. it is always wide enough to contain "THIS STRING" without wrapping, or wasting any space.
I would like to do this as I have these TableLayouts within a ListView, so it looks very poor when the last column is of variable widths.
I have tried obtaining the string width, even going so far as to put it into a TextView, call getTextSize() then setWidth() on all appropriate TextViews. The problem I hit there is that gettextSize() returns pixels, but setWidth uses ScaledPixels.
I'm sure there is a really simple solution. Can anyone help?
