I'm trying to center a button in relative layout, is this possible? I've tried the Gravity and Orientation functions but they don't do anything.
Can anyone tell me how can i do this using Java code or in activity class? I do not know how to set android: layout_alignParentBottom="true".I want to implement whole view via java code.

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 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.

I am working on a fairly basic screen layout for my first Android application and running into some issues. My goal is to have a TextView in the top left and top right corner, a large "hello world" TextView in the exact middle of the screen, and then a button at the bottom of the screen.My issue is, to center the "hello world" TextView vertically, I need to set the layout_height="fill_parent".However, this causes the middle TextView to cover and hide the button at the bottom of the screen. Is there a better way to do this than what I am currently trying?
View 1 Replies View RelatedI have a Linear Layout, which only contains one button. I want this button to be centered vertically and aligned to the right. I tried many ways, but I couldn't make this button centered vertically. It is always aligned to the top. I also tried to put a button in Relative Layout, the button can not be centered vertically either. The XML is as below. Is there anything wrong with this layout? <?xml version="1.0" encoding="utf-8"?> <Linear Layout xmlns:android="http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="#E8E3E4"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="More" android:layout_gravity="right| center_vertical" /> </Linear Layout>

I have the Button defined as follows:
CODE:..........
The problem is that 'drawableTop' image is aligned to the top border of the Button view. I would like to center it (together with text label) vertically on the button. 'android:gravity' seems to work only on text label. It does not affect 'drawableTop' positioning.
I was able to center it vertically using 'android:paddingTop' - but that does not seem to be a good idea. I guess it would not work properly on different screen resolution/size.
Can this blank button in the center of the lock screen be assigned to anything?Also, can anything be added to this menu? i.e. wi-fi and bluetooth?

View 8 Replies View RelatedI have a layout question.
Say I have a RelativeLayout appearing at the bottom of my screen. In this, I want to add 2 textviews, in the center, one in the top center and one in the bottom center.
|--------------------------|
| Text1 |
| Text2 |
|--------------------------|
Something like that.
I have found ( and I willing to bet many already know this) that the sensor in the upper right side of the screen is what determines if the button lights are on or off. In a well lit room the lights will be off, if you cover that sensor or darken the room the lights come on.
What we need is someone smarter than I am to make an app or widget that disables that sensor when the phone is in the dock, if that is possible.
I can't send sms's from my x10 and i ask support and they told me to put the servise center manully in wireless control<mobile network> service center number. but i couldn't find that in my phone!!!

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 );

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?
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" />

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?
