Does anybody know how to do the same thing but in "dip" ?
I have a custom view, derived from Button, which I want to position at runtime, relative to another view. Because I don't know that other view's position yet when my view is being inflated (because layouting hasn't started), I leverage the onSizeChanged handler to set my view's position relative to the other view. code...

I have a Relative Layout.
Which has 2 buttons, side by side and it is right-aligned.
So this is my layout xml file. My question is there are no spacing between the right-most button and the right border of the RelativeLayout and between the 2 buttons. How can I add that? I play with android:paddingRight, but nothing helps. code...
There is an repeating background attribute like in css for layout on Android API?
View 5 Replies View RelatedI know my original post (at http://groups.google.com/group/android-developers/browse_thread/threa..., I could not find a way to perform a reply, maybe it's too old) is not sexy, but I'm now facing that problem in many situations. Let me please rephrase what I attempt to do, and what my problem is.
I have a RelativeLayout made of three widgets (named 1, 2 and 3 on the illustrations below): one attached to its parent left border (labelled 1), one to its parent right border (labelled 2) and the third (labelled 3) inserted between the 2 previous ones (its left border is attached to the first widget right border, and its right border is attached to the second widget left border). The third widget (the middle/central one laballed "3") is far taller than the two others, and I would like the first and second items (1 and 2) to be vertically centered with the middle widget.
I have resorted to the "android:layout_centerVertical" attribute for both the first and second widget, but I do not get the expected result. See at the bottom the various layouts I'm mentionning. Could someone please help me, and tell me whether what I intend to do is feasible, and how? Thank you for your time.
Layout with no "android:layout_centerVertical" specified: ------- |1|3|2| --|3|-- |3| ---
Layout with "android:layout_centerVertical" set to "true":
--- |3| |3| |3| ------- |1| |2| --- ---
What I'd like: --- --|3|-- |1|3|2| --|3|-- ---
I've always been using RelativeLayout everytime I needed a View container, because of it's flexibility, even if I just wanted to display something really simple.Is it ok to do so, or should I try using a LinearLayout when I can, from a performance/good practices standpoint?

Since I'm still just learning Android (and it appears Amazon says it'll be 2 months till I get the Hello, Android book) I'm still playing around with doing simple things. I have no problem getting an icon to display with the click of a button on my RelativeLayout using ImageView. The code for creating it is as follows:
private int mIconIdCounter = 1;
private ImageView addIcon(){
ImageView item = new ImageView(this);
item.setImageResource( R.drawable.tiles );
item.setAdjustViewBounds(true);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT );
if( mIconIdCounter != 1 ){
params.addRule(RelativeLayout.RIGHT_OF, 1 );
}
item.setLayoutParams( params );
item.setId( mIconIdCounter );
++m_IconIdCounter;.......................

View 1 Replies View RelatedI'm trying to build an android application that features a graphical display drawn within a RelativeLayout. I want to place "+" and "-" buttons next to several of the parameters, which are drawn at various points on the canvas. The positions are free-form don't seem to conform to any of the standard XML layouts.I know how to create the buttons programmatically, but I don't know how to place them over the canvas where I need them to be. I'm assuming that this would be done in the view thread's doDraw() method, after all the graphics have been drawn, but how?
View 2 Replies View RelatedI have ScrollView with RelativeLayout as a child of ScrollView. I am trying through JAVA code to set Layout_Gravity to CENTER so my RelativeLayout is centered (horizontally and vertically) in the middle of ScrollView (that covers whole screen).This works fine in XML and produces desired result, but when I try to do this programmatically, it seems there is no way to set Layout_Gravity of RelativeLayout. I tried using LayoutParams, but couldn't find anything there that would help me to center RelativeLayout in the middle. So, am I missing something or this simply can't be done?
View 7 Replies View RelatedI have the following structure defined in an xml layout file.
<RelativeLayout android:id="@+id/mainLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<FrameLayout android:id="@+id/frame" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" ></FrameLayout>
<Button android:id="@+id/button" android:layout_below="@id/frame" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</RelativeLayout>
The FrameLayout is positioned correctly in the center of its parent. But the Button isn't getting positioned under it. Instead it's displaying in the top left corner. Am I doing something incorrectly or is this a bug with RelativeLayout?
As i am facing limitation of layout depth in my application, i am replacing some LinearLayout with RelativeLayout. However i am stopped by a supposely very simple issue (but apparantly without clean solution regarding that http://stackoverflow.com/questions/1499555/android-layout-centering-i..., nor in the ApiDemos sample where RelativeLayout are too simple):
How can i align vertically 3 items (in a simple way!) which are on a horizontal line with RelativeLayout without?
does not seem to have any effect at all.
Here is the xml; in this example i would like an icon at left (fixed width), a text label in the middle (fixed width) and an edit text on the right (remaining space). the problem is that the TextView seems to ignore the parameter android:layout_gravity="center_vertical", and seems to be top aligned with parent. code...
Of course i can use marginTop/Bottom and alignTop/Bottom on each single item but that's not very clean.
I created a background .png for my application in GIMP. It's resolution is 640x480, which from googling, seems to be the resolution for a default emulator. My problem is when I apply the background to the RelativeLayout with android:background=@drawable/bg and run it, there are lots of artifacts in the image. As if the emulator could not provide enough colors to display the .png correctly. This image is nothing to fancy, just simple lines and radial gradients.
View 1 Replies View RelatedIn my Android App Activity, I have a RelativeLayout with one ImageView and a couple of TextViews being populated at runtime. I also have a Save button in the activity that I use to save the image in the ImageView to the device SD Card. Now what I really want to do is Convert the elements (image and the text in the RelativeLayout) together to a PNG image when the Save button is clicked and Save it to the SD Card. Have anyone tried a conversion like this before? It would be very helpful if someone can give me some hints or code snippets on how to go about doing this?
View 1 Replies View RelatedI'm starting to use RelativeLayout more and more but there are some things I keep running into.
Say I have a status textview that I want top and center. Then I have a bunch of other objects below it like images and a table layout.
I want the stuff below the status text view to respect the status textview's personal space and not draw themselves right on top of it.
But what I'm seeing is that in a relativelayout, everything piles up on eachother unless I use alignment such as android:layout_below and android:layout_above.
Is there an attribute that I can add to the status textview to make it so other objects don't want to draw right on top of it? Or do I have to keep using the alignment tags on everything and align things away from it?
I have an Android Activity with a RelativeLayout and I have implemented the following method to prevent the activity from being recreated on change of Orientation:

I am obviously not doing anything in this method, but it worked perfect when using a LinearLayout. Now however, using RelativeLayout, my layout is all messed up when changing to landscape orientation.

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?
I have a layout that has just a ScrollView visible. It has a relative layout as its child. This layout has several other layouts (mainly text views) as its children. When the text is not big enough, the scroll view does not expand itself to fit the whole screen. Instead, it shows a gap at the bottom where the background shows. I tried setting fillViewPort=true on the ScrollView, but that just made the first child layout (RL1) to fill the screen.

The format of the data in the geodb file is as follows :
address 1 latitude "38.898763" longitude "-77.036655" line 0 "1600 Pennsylvania Ave NW" line 1 "Washington, DC 20006" locality "Washington" region "DC" postalCode "20006" countryCode "US" countryName "United States"
and following is the code snippet : Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses=geocoder.getFromLocationName("1600 Pennsylvania", 10);
