I have an Activity which uses a layout with a LinearLayout in it. Now I want to create in runtime a subactivity which loads some other layout and add this layout as item of my LinearLatout.

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.

View 2 Replies View RelatedI need to load several ImageViews into a layout. The ImageViews are used to show a rating using 'star' icons. The number of stars (i.e. the rating is determined during loading by reading a configuration file.
The ImageViews are sitting inside a RelativeLayout layout.
Currently I am using something like this:
CODE:........
My quesions are:
1) Is doing the loading dynamically (not using an xml) is the 'right' way of doing this ?
2) If it is, how do I make the stars display in a line, currently they get placed one on top of the other.
I am probably missing something totally obvious, but can someone tell me how to add padding between buttons of a Linear Layout?

I was looking over this code about extending an ImageView: http://marakana.com/forums/android/examples/98.html
And i was wondering how can i add the new View to an existing xml layout file, along with some other views.
Already i did this inside my main linear layout:
CODE:..........
But the problem is that this way the onDraw method doesn't get called.
Maybe some examples where you combine CustomViews with xml layout.
I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).
The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.
I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

I have a LinearLayout defined in XML that I want to use repeatedly to display elements of a list. The XML-layout looks like this:

I gather information about certain events from a webpage, and then I want to display all events in a list using the above layout for each event. My current approach is to have a LinearLayout as parent and then adding each event as a row.
Problem number one is to add the layout to each event (the number of events is varying). I.e., I want to dynamically inflate this layout for each event. I also don't want the text to be hard coded into the layout (as above) but added at runtime. I don't know how to do this. I have tried something like the following without any success.
LinearLayout eventView = (LinearLayout) findViewById(R.layout.event);
parentView.addView(eventView);
Problem number two is then to add these layouts to the parent view group and display it on the screen. When I try to do this using parent.addView(child), the program crashes at runtime and I can't figure out why.
It's kind of hard to describe the specific problem, since I'm new to GUI-programming on Android and I'm sort of programming by trial and error right now. Anyway, if you are able to help me with some of the problems it would be greatly appreciated. Linus
EDIT:
The problem now is adding text dynamically to the TextViews. I try this:
TextView dest = (TextView) findViewById(R.id.destination);dest.setText("myText");
only to discover that dest is null. Any ideas why and how to fix this?
EDIT 2:
I have narrowed the problem even more, but I really don't understand its nature. This is the trouble-method: Code...
it somehow works (even though the events are displayed in reverse order). Anyone knows what's going on here?
I'm very new to Android programming, so this is probably something pretty basic. I just have an xml layout with a few buttons. I'm trying to follow the model given by the JetBoy demo, so I'm adding a view to the layout which extends SurfaceView. When this new view is put in my xml layout, I just get a blank screen.
Here's the XML layout if it helps. The gameview element is what causes the screen to be blank

We are making an application that needs to convert one file format to another. I am not sure whether we can add a JAR file in which we develop the code to convert the file format to our required file format, to our android project.
View 1 Replies View RelatedI kept my .apk file in my "apache" webserver at "Document root" path. This is the only file at Document Root . I had removed index.html file at this location. If I keep the index.html file then other files where not displayed if I open the URL i.e http://<ip_address> using a web browser Now from my Google phone browser I'm able to download the apk file and and install it in Google phone. Note 1: I had not done any settings to add the MIME type "application/ vnd.android.package-archive" in apache web server. Note 2: I was connecting to my webserver through WiFi. But the same apk file I was not able to download from my Gmail (as attachment) and I got "unknown file type" error in this case. After reading few related topics, I came to know about the MIME type support required in webserver for android applications. Now I'm wondering how come file gets installed sucessfully from my apache webserver even without adding the MIME type "application/ vnd.android.package-archive". Any clues what's happening here?
View 4 Replies View RelatedSo my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my imageview to be at the bottom. However, a child of a ScrollView dont seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?
I love the native music player that comes stock on android (via google music). I also use a mac, and I'm in Canada (so I can't take full advantage of the google music service, I.E. storing music in the cloud and managing it that way. In order to put music on my android phone i simply select the songs in my itunes and and drag them into the music folder in Android File Transfer. This works, however, there is one problem: the songs aren't organized into folders, which makes it extremely difficult to organize / delete music from my phone when I want to, as the songs are organized as 01 01 01 01 01 01 02 02 02 02 02 02 03 03 03 03 etc. I tried to right click the music folder and say new folder but it won't create that folder in the music folder. I tried moving the songs into that folder then dragging it into the music folder but that won't work.
I really don't want to use double twist, because I have in the past, and I don't really like it all that much. I just want my files to be organized into folders so that when I can delete them later when I want to.
I've been trying to create a Compound Control in Android 1.5 (as described here) but haven't been able to find any good examples on how to do this using an XML file to specify a layout. Create Custom Component based on LinearLayout, declaring layout in XMLI'm fine with creating an Activity and then loading an xml file using the following in the constructor:
setContentView(R.layout.main);
However, I want to do this in subclass of LinearLayout - so I can use this compound component in other XML layouts. Something along the lines of:
public class CustomView extends LinearLayout
{ public CustomView(Context context) {
super(context);
setupView();
} public CustomView(Context context, AttributeSet attrs)
{ super(context, attrs);
setupView();
} public void setupView() {
setContentView(R.layout.custom);
// Not possible } }
What is the correct way of going about doing this?
In my layout xml file, I have included other layout xml file (each with a different android id).But when I run it in the emulator, and start Hierarchy Viewer, each of the layout still shows 'NO_ID', and in my code, I have findViewById(R.id.test1) and findViewById(R.id.test2) both returns null.Can anyone please help me with my problem?

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.
