Aug 2, 2010I 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);.............
Android :: Multi Column Custom List View / With Editable Edit Text At End Of List View
Nov 3, 2010I 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).

Android :: Combining Map View And List View In Application
Aug 4, 2010I 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?

Android :: Check If The View Is Visible On The Window
Sep 4, 2010What's the best way to check if the view is visible on the window?
I have a CustomView which is part of my SDK and anybody can add CustomView to their layouts. My CustomView is taking some actions when it is visible to the user periodically. So if view becomes invisible to the user then it needs to stop the timer and when it becomes visible again it should restart its course.
But unfortunately there is no certain way of checking if my CustomView becomes visible or invisible to the user. There are few things that I can check and listen to: onVisibilityChange, it is for view's visibility change, and is introduced in new API 8 version so has backward compatibility issue onWindowVisibilityChange, but my CustomView can be part of a ViewFlipper's Views so it can pose issues onDetachedFromWindows, this not as useful onWindowFocusChanged //Again my CustomView can be part of ViewFlipper's views. So if anybody has faced this kind of issues please throw some light.

For that data processing to be started I also need to know a visible size of my main View (which is a LinearLayout currently, but whatever).I wonder how to do that. I.e. I wonder what is the entry point (callback?) I should use to be sure that my main View has been layed out, so i can use view.getWidth/getHeight? Is creating a custom View and reimplementing it's onSizeChanged() - the only way? In this case how should I properly describe it in my xml layout file? (it will contain some child views)

Android :: Graphically Represent Multiple List Selections / Dynamically Change List Item View
Apr 23, 2010I'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.
