Android : Way To Create A JTree-like Widget For Droid?
Aug 26, 2010
I need to create something like a JTree for my app and have been looking at ExpandableListView, but it only allows two levels. Does anyone know if it's possible to extend this to an arbitrary number of levels? I need a single top level and, below that, several second levels, each of which may contain their own levels. I would expect that one could set a second-level (child) item to be an ExpandableListView of it's own, but it doesn't seem possible. Thanks for any help on this, as it's holding up my entire project.

I am looking to create an android widget for my application. It is a static widget, meaning it does not periodically update itself with new data (like google search widget)? If that is the case, do I still need to create a service like the Word Widget sample in the android sdk?

I can create a static widget without thinking, I can even create a widget like the analogue clock widget that will update itself, however, I can not for the life of me figure out how to create a widget that reacts to when a user clicks on it. Here is the best code sample that the developer documentation gives to what a widget activity should contain (the only other hint being the API demos, which only creates a static widget):
public class ExampleAppWidgetProvider extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch ExampleActivity
Intent intent = new Intent(context, ExampleActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider_layout);
views.setOnClickPendingIntent(R.id.button, pendingIntent);................

I am trying to find a way to create a widget and the program on the same app so that i can give the user the choice to add to the home screen either the dynamic widget or the normal program, same functionality for both except that the widget would run a service to update every x hours and the program won't. Similar to what "bbc news" and "weather bug" have done. I am guessing that something needs to be added to the manifest but i have not found any documentation for it. Can anyone help on this?

I have read the LabelView example in APIDemo which show how to create a custom widget.However, what if I want to create a custom widget which is a composite of existing android widget?I know my custom widget need to be inherited from view, but if i do that, I can't do 'setContentView()' in my custom widget class (since that is an Activity method).so how can I apply the above xml to my custom widget class?

In ApiDemo, there is a progressBar demo. It creates a horizontal progress bar with a xml.
<ProgressBar android:id="@+id/progress_horizontal" style="?android:attr/progressBarStyleHorizontal" android:layout_width="200dip" android:layout_height="wrap_content" android:max="100" android:progress="50" android:secondaryProgress="75" />
But how to create one programmatically? If just new ProgressBar(fContext), it is Default ProgressBar style.

I tried out Flyscreen the other day and found its card-based flipping through rss/facebook/twitter/weather to be very fluid and pretty. The trouble is, I don't really want that as my lockscreen (besides which, it doesn't seem to truly lock the screen). Does anyone know of a similar app that creates a widget I can flip through in a similar way on a homescreen?

I need to create desktop shortcut for content managed by my app. I've found the way to do it using ACTION_CREATE_SHORTCUT But I need the way to implement it without using "Create shortcut" menu. It would be great if user could select "create shourtcut" from item's context menu inside my activity and it will be automatically placed on desktop.

I posted this question sort of embedded in the "show us your Droid X screen" but I think it got buried with all the "what is that widget?" questions.I see on some screens the picture widget picture is big. Mine is only about 1 inch by 1/2 inch.I can barely even get 1/2 a face in the picture.How do you get a bigger picture?I'm running LauncherPro, is that effecting it?Since I couldn't get a bigger picture, I decided to try and add the slide show widget. But when I try, it says Widget Conflict only one photo slideshow per home screen. I don't have any other slideshow widgets on my screen. Any ideas?

Now I want to add action when an image of the gallery is shown(each image's width is the same as screen width), so I need to get its index in the image array. My question is how to get the index of the image which shows on the screen?
