View 4 Replies View RelatedI am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

View 13 Replies View RelatedI am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
I'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.

I am working on an application where I need to display some locations on a map and in a list view where the user should be able to toggle between these views(activities?). I want the toggle button(s) to be in my custom titlebar like in the images (if they are attached). What is the best practice for this? Tab view seems like a solution but can I customize the tab buttons? Should the map and list be in different activities or the same? Now I have two different activities one extending MapActivity and one extending ListActivity but no way to toggle between them. Is it possible to load activities into a FrameLayout?

View 1 Replies View RelatedAn application I'm developing requires that the app main a local list of things, let's say books, in a local "library." Users can access their local library of books and search for books using a remote web service. The app will be aware of other users of the app through this web service, and users can browse other users' lists of books in their library. Each book is identified by a unique bookId (represented as an int). When viewing books returned through a search result or when viewing another user's book library, the individual list row cells need to visually represent if the book is in the user's local library or not. A user can have at most 5,000 books in the library, stored in SQLite on the device (and synchronized with the remote web service). My question is, to determine if the book shown in the list row is in the user's library, would it be better to directly ask SQLite (via SELECT COUNT(*)...) or to maintain, in-memory, a List or int[] array of some sort containing the unique bookIds.
So, on each row display do I query SQLite or check if the List or int[] array contains the unique bookId? Because the user can have at most 5,000 books, each bookId occupies 4 bytes so at most this would use ~ 20kB. In thinking about this, and in typing this out, it seems obvious to me that it would be far better for performance if I maintained a list or int[] array of in-library bookIds vs. querying SQLite (the only caveat to maintaining an int[] array is that if books are added or removed I'll need to grow or shrink the array by hand, so with this option I'll most likely use an ArrayList or Vector, though I'm not sure of the additional memory overhead of using Integer objects as opposed to primitives).
I have a click event hooked up to my listview.I need to pass a string param to the new intent based on which listitem they clicked on. The value I want to pass is in the listitem called txt_Genus. How do I get that value out of the listitem to pass to the intent?

View 3 Replies View RelatedI'm very new to Android and Java development, searching and reading various tutorials and using different parts of code from around the internet, trying to make sense of it as I go. Currently I have a list created with 4 list items, what I'd like to do is assign a different icon to each of these list items, however, I've no idea how to do it, nor do I know what to search for.

String[] myList = new String[] {"List 1", "List 2", "List 3", "List 4"};

listObjects.addAll( Arrays.asList(myList));
myListAdapter = new ArrayAdapter<String>(this, R.layout.row, listObjects);
mainListView.setAdapter(myListAdapter);
} }
