I want to build a list that show the directory tree like list similar to folders view on the left pane in 'Windows Explorer'. I have seen ExpandableList but this goes into 2 levels only. I want to go into multiple levels. Expand the item by clicking on the left icon and show sub directories in it. Click on sub directory expand icon, show the sub-sub diretories in it and so on.

I'm happy reading and writing to a pre-set file, and could manually populate a listview, but I'm hoping there is an official(or not) filebrowser I missed, or other more elegant solution to present the user with a directory listing, and let them select a file.

View 3 Replies View RelatedI have an Android app where users can add items to a ListView, and I'd like them to be able to re-order the items in the list however they want (as opposed to just offering them different sort orders). It's easy enough to add a position setting for the items (they come from the DB) but what kind of UI elements are available for the user to indicate the desired ordering? Is there a pattern anyone has seen implemented for this? I have not seen anything on Android that does anything like this, except the home screen which is similar but looks a little bit beyond my expertise at this point. The best I can think of is to use a long click and context menu to "move up" or "move down". Any better ideas?
View 2 Replies View RelatedI need an advice. What is the best way to implement in android a list of such UI elements (see the ref)A list contains a lot of such elements (about 30-40). I'm using now relative layout and 4 text fields and I think it isn't a good way.I think it's too heavy (full list will contain: 30 relative layouts and 30*5 = 150 text fields).

View 1 Replies View RelatedI don't see anything about this change in the API differences report at http://developer.android.com/sdk/api_diff/8/changes.html. However when my Nexus One started running Android 2.2, the list of files created by the following code are now in reverse alphabetical order rather than alphabetical order (as they were with Android 2.1 and earlier, AFAIK):
CODE:.........
The line "Arrays.sort(fn);" revives the alphabetical order of the list, but sorts are computationally expensive and AFAIK the explicit call to Arrays.sort() was unnecessary prior to Android 2.2.
In addition to seeing this order change on the Nexus One, it can be confirmed on the emulator running level 7 and level 8 AVDs.
I want to display the same options menu on all of my application's activities. I created a generic Activity that implements the menu, and all my further activies extend it. The problem: when I need to extend other specific activities, like ListActivity and MapActivity, I can't figure out how to extend the generic activity and add the List or Map behaviour to the new class. To deal with the issue I had to create three different generic activities, each extending Activity, ListActivity and MapActivity.I've tried creating an abstract activity but it doesn't work, I would need to extend two classes at the same time. I could try interfaces but since I can't implement methods, I would have to paste the menu implementation all over the second-level classes, right?

At some points while running my android application, I need to create a directory on the sd card, for a small number of users this fails and I can't figure out the reason for it... (I've found similar problems caused by the WRITE_EXTERNAL_STORAGE permission missing, it's there and it works for almost all users so I don't think this is reason) When mkdirs returns false I crash the program and log the following java.io.File properties, starting at the directory I want to create, then recursive printing properties of the parent directory and so on...
/sdcard/MyDirectory/Dir1/Dir2 (exists: false, canWrite: false, isDirectory: false, isFile: false);
/sdcard/MyDirectory/Dir1 (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard/MyDirectory (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard (exists: true, canWrite: true, isDirectory: true, isFile: false);
/ (exists: true, canWrite: false, isDirectory: true, isFile: false);
The strange thing is that the parent directory is writable (canWrite=true), I can't print the execute file permission but from what I've read, write is what you need when creating directories... What I've looked at so far is the WRITE_EXTERNAL_STORAGE permission, if the sd card is full and if the sdcard is mounted read only:...........................
I have an app that instructed me to copy some data from my computer to the SDCard. So I plugged the Droid into the computer, mounted my Droid SDCard, looked at the directory, and copied the file. There are a bunch of files and folders listed (e.g. backups for apps, album artwork, etc.) as being on the SDCard. But when I go into Astro on the Droid and select "SDCARD" it shows "directory is empty." I don't get it. Why can't I see the folders and files on the SDCard that I can see on the computer screen?

The number of contacts is not predefined. Any thoughts on how to push this into a ContentProvider in one go? I basically dont want my application to worry about the hierarchy and bulk insert or something, I want to hand this responsibility over to the ContentProvider.

I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. I want my first screen to present the user with a list of activities to choose from. In my situation it is a recipe app where the user first chooses the type of food, such as, Beef, Chicken, or Pork. I want the application to launch an activity depending on the list item that the user clicked on. I am not sure if I should use a list view, a text view, a scroll view, a list activity, an activity group...

View 4 Replies View RelatedI'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

View 1 Replies View RelatedI'm trying to tackle a problem that seemingly many Android developers have, which is how to intersperse lists with non-list data, in one big scrollable pane.The model I have in mind is the screen for an individual app in the Market. You have a big description, a list of a few lazily loaded comments, and then some individual items that do different things, like visit the developer's web page, call them, etc. And then in between them all, are nice section headers.Emulating this approach seems to be extremely hard. I've read enough SO answers and mailing list posts to know not to put a ListView inside of a ScrollView, but I want the same effect without using addHeader() and addFooter() with very complex header and footer views. I've tried using a LinearLayout that I stock with views myself, but I can't get the pleasant click effects that default list items have (the orange background, white for long-click, etc.).
