Android :: Vertically Align Items In RelativeLayout?
Jun 9, 2010
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.

The row of my listview has 3 texts. What I want to do is to align all the rows texts vertically. I tried that using the TableLayout view for the row, and I've set the width for the first and third cell's as a constant. I'm not very happy using constants because of the porting issues. Is it possible to align these texts without in another way? Here is the layout...

I have tried everything and I can't seem to be able to get Month or Day of Month to align vertically as shown in the picture below.
Is this even possible? I know it is using the Week Bar, but I'm not so sure about the others. I can't figure out where the option is to make anything else besides the Week Bar go vertical like someone did in the picture below. Is this picture just a fake or what?

I have a ViewGroup and it has a few children. And one of them is a TextView ("+id/text"). In my code, I would like to know how can I add a new View or ViewGroup which will be positioned vertically aligned and below the TextView (+"id/text")?I have followed the advice below and try to use TableLayout. As a test, I try to layout statically to make sure things are aligned correctly. Here is my layout xml:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="@+id/panel" xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight">
<TableRow
android:layout_width="fill_parent"
android:layout_height="wrap_content">..........

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.

Had no problem getting my phone to play nice with our exchange server at work and emails are coming/going fine.
However, there are some configuration items I have a big issue with as it relates to the 'look' of the email (coming from a BlackBerry).
1. Is there any way to have a single folder show my received items and sent items combined? My BB had this and it was very useful.
2. How can I edit the way my folders are displayed at the top horizontal bar? The sidescrolling folder display is awkward, it puts my inbox first (good) but then all subsequent folders are listed alphabetically; it pays no attention to their order on my desktop and also shows sub-folders of other files. Any way to change this?
3. Is there a way to change the way emails show as unread? The difference b/n read and unread is only a shade of grey, and difficult to see outside.

I 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;.......................

I'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?

I 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?

I 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?

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.

In 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?

I'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:
CODE:..............
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.
What is the most efficient way to have the screen redraw correctly without having the activity restarted again with a call to onCreate?

I am trying to display two TextViews in two separate line. For that, I am using RelativeLayout. I don't want to use XML for layout as I want to bundle this Activity in a jar file which may be used by different APKs. The TextViews are being overlapped instead of being displayed on two separate lines. Any idea what I am doing wrong here? Sample code is below.
