I was wondering if it were possible to dynamically create an XML layout file to be displayed to the user. The idea would be to be able to retrieve a layout file from a central server, which could display this dynamic, server driven GUI.

not sure how to inflate this from my layout file: MyView v = LayoutInflater.from(this).inflate(R.layout.myview, null); the inflater of course does not know what 'MyView' type is, and returns only View. What's a good way to reconcile this?
View 1 Replies View RelatedOther questions say that the style cannot be set programmatically, but a View can be initialised with a style such as when it is loaded from XML.How can I initialise a View with a particular style programmaticly (not in XML)? I tried using View(Context context, AttributeSet attrs, int defStyle), but I don't know what to parse in for the second argument. Passing in null results in the View not being displayed

I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now.The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application.Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through.I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful.EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)
View 2 Replies View RelatedI am trying to improve the layout for my game. The problem is that while I can create a good layout for one android phone, it doesn't work for another, ie the trackball for MyTouch is on the right side (landscape mode), but for the MyCliq, the DPad is on the left side. Is there a way to programmatically set the layout based on which phone it is?
View 2 Replies View RelatedI have this element in my layout XML:
<FrameLayout android:id="@+id/FrameLayout01"
android:layout_width="320sp" android:layout_height="380sp"
android:layout_gravity="center" android:background="#99CC33">
</FrameLayout>
And I want to get its position on the screen with getTop(), getBottom() but I want to do it only once.
I was trying to do it on the onCreate(), but those methods return all 0 as response.
I've created an Activity subclass called CustomTitlebarActivity. Essentially, each main activity in my app will have a custom titlebar with many common features such as a Home button, a title, a search button, etc. In my current implementation, I am still explicitly using an include statement in the layout XML for each CustomTitlebarActivity: <include layout="@layout/titlebar" />
It seems natural that I should be able to do this within CustomTitlebarActivity. I have two questions: What code can replace this include tag, and where should I put the code? (My first instinct would be to put it in CustomTitlebarActivity's setContentView method.)
On a related note, I would appreciate insight into better ways to reuse android UI code (even if, per se, the titlebars need to vary slightly between activities.)
Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.
I want to do this entirely in an xml layout file. When I put ImageButton xml tags inside a GridView xml body, The layout panel in eclipse is throwing an exception: UnsupportedOperationException:addView(View, LayoutParams) is not supported in AdapterView.
Is it possible to create a layout based on (background) images? For example, there is well know app called Appie that uses this picture as a homescreen:
I might be able to recreate the layout with a TableLayout, but this will be difficult to get it perfectly aligned with the buttons in the image. The default layout options make it very difficult, or maybe impossible, to allow for selection of the buttons on the image (especially when the buttons are in an arc-path). Can anyone tell me how this is done?
Let's say that I have two layouts for a widget: Layout1 and Layout2. The default for the widget is Layout1, but I allow the user to choose which layout they want the widget to be. So if the user changes to Layout2, how do I programmatically change the layout to Layout2? There isn't a setContentView method for widgets like there is for Activities.
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?

I'm programmatically adding views to a LinearLayout inside a ScrollView and i'm running into some issues setting margins and padding etc for child views of the LinearLayout.

I'm starting a calendar app and I'm trying to figure out what the best way to create the layout is. I don't want to use the built in CalendarView as it's only in API >11 which limits the potential users too much.
I've toyed around with a GridView with and Adapter behind it. Truth be told I'm still figuring out how that one works, but it seems the most promising.I tried a nested LinearLayout of TextViews but that requires accessing each TextView be it's ID.
I'm creating a menu in XML using the eclipse software.Unfortunately, I'm no expert in XML but I have attempted to create a basic menu.
The issue I'm having is the alignment of the menu buttons. The buttons on the left column are smaller in width compared to the buttons in the right column. I know this may not seem much of an issue now, but the problem is made worse if I edit the text value of the buttons.
I want to achieve even distribution for both columns of buttons but I have been scratching my head trying to figure this one out!

Im using an inflater inside an adapter for my listview. I need to add in a different button depending in the state of the data for each row, so Im thinking I need to do this programmatically, but how do I make sure its inserted into the correct place inside the layout?
View 1 Replies View RelatedThe android docs say that it adds the runnable to the queue and it runs in the UI thread. What does this mean? So, for example, the same thread I use to create my layout is used to run the Runnable? What if I want it as an independent thread that executes while I am creating my layout and defining my activity?

My application will have two layouts, one for large screens and one for normal. For testing I'm working with one phone (800x480 240dpi) and one tablet (1024x600 240dpi) but both are detected as large screen hdpi and long aspect ratio, so I'm not able to assign different layouts.
The only approach I think that can work is to create layout-large and layout-normal, get the resolution and programmatically set the layout folder. Is that possible?

How can I create a XML file that has identation or, at least, line breaks between each tag? I'm using class XMLSerializer (available in Android) to handle the XML creation.
XMLSerializer serializer = new XMLSerializer();
StringWriter writer = new StringWriter();
serializer.setOutput(writer);
String xmlFileContents = writer.toString();
Then I use the contents of xmlFileContents to create a file, using a BufferedWriter. The file is written, but the XML is not idented, and would like it to be.
I created a sample project using the below command:

I would like to write a file to the SD card from my application, but the following code throws an IOException when debugged on a T-Mobile G1:
String p = Environment.getExternalStorageDirectory() + "/log.txt"; File recfile = new File(p); recfile.createNewFile();
The last line throws an IOException with detailMessage = "Cannot create: /sdcard/log.txt". The MOUNT_UNMOUNT_FILESYSTEMS permission is set in the manifest. And yes, I really do want to write to the SD card; I don't want to use the logging features Android includes for this particular application. The Android documentation does not seem to give any specifics on how one might write files to removable storage in "Data Storage" under "Framework Topics". What am I doing wrong, or where can I read more about this topic?
