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.

I have a problem with two Textviews on the same height in a RelativeLayout running into each other.
I use the following Layout.
CODE:...........
This gives me this view:
Everything is as I need it except the two textviews name and information are displayed on the same screen space with the one on top of the other.
I'm trying to get something like this: http://img202.imageshack.us/img202/552/layoutoy.png. I'm using this as a list item (technically as the group view of an ExpandableListView).
Here's the XML file. code...
But this doesn't work. The Button doesn't wrap its contents, instead it uses all available horizontal space. The TextView does wrap its contents, but what I want it to do is to cut off when it overlaps the Button.
In other words, I want all the buttons to be of the same width, regardless of the amount of text in the textviews. Is this at all possible?
I want to create a self contained library that I can easily drop into an android project and run.I can do this by creating a shared object via the NDK and JNI but the limitation there seems to be lack of audio support which is important for this library.Is there a way to create a library in the java/android world? Ideally the developer could just drop it into the project and could access methods via headers maybe?Any help/samples would be fantastic and appreciated.

View 12 Replies View RelatedAccording to this SDK guide, unit-testing a Library project can be achieved by creating a standard application project, reference the Library project and then instrument the application for unit testing. However, when I do this and launch the test application I get the message.No tests found with test runner 'JUnit 3".I'm using Eclipse and the Android ADT plugin, all latest versions.the projects compile just fine. The test project also installs fine to the emulator. But in the console I can see that it looks for <library>.apk, which of course doesn't exist since I'm compiling this as a library into the test project.

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...
I have 5 text views to be added horizontally,and it needs to occupy the displaywidth.When i change the screen orientation,it should change based on it.Is that can be done by Layout or it should be done programmatically..

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?

View 1 Replies View RelatedI have a class that extends android.app.Dialog, the layout is done in an xml file, and the setup (button listeners, etc) is done on the onCreate method.

What is the common way to clear these text fields?
View 2 Replies View RelatedSince 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;.......................
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.
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?
