[android-beginners] Two Problems with ExpandableListView
Very pleased :) with the way ExpandableListView works but am unclear
how to set the clicked view as invalid in OnDismiss.
Problem One
---
In the onChildClick(ExpandableListView parent, View v, int
groupPosition, int childPosition, long id)
{
I call the Dialog Enter and wait for dismiss so:-
Value = new Value_Input(test2.this,0, custno, itemno, day);
Value.show();
Value.setOnDismissListener(new OnDismissListener() {
public void onDismiss(DialogInterface arg0) {
getExpandableListView().invalidateViews();
}
});
}
the invalidateViews() seems a bit heavyweight when I only want to
redraw the clicked view.
the other options are:-
getExpandableListView().invalidate();
getExpandableListView().invalidate(dirty);
getExpandableListView().invalidate(l, t, r, b)
getExpandableListView().invalidateChild(child, dirty)
getExpandableListView().invalidateChildInParent(location, dirty)
getExpandableListView().invalidateDrawable(drawable)
basically how do I get from groupPosition, childPosition to the View
after the event??
or how to use one of the above??
What I need is:-
getExpandableListView().invalidateChild
( groupPosition, childPosition)
Problem Two
--
How do I get the adapter not to draw GONE views. I have tried the
trick I used in the simple BaseAdapter in both getGroupView and
getChildView but it does not work :-
boolean found=false;
int count = getExpandableListView().getChildCount();
for(int i=0;icount;i++){
View block2 =
(View)getExpandableListView().getChildAt(i);
if (block2.getVisibility()==View.GONE){
found=true;
}
}
if (found){
getExpandableListView().forceLayout();
getExpandableListView().getParent().requestLayout();
getExpandableListView().invalidateViews();
}
What do I do??? Why doesn't the adapter look after this for me??
I would argue that both of the above problems currently require the
user to have an understanding of what is going on inside the adapter
other than the basics. (dangerous) Or am I missing something basic??
Many thanks in advance
Steve

[android-beginners] SimpleAdapter onClick event catching. How to?
Hi, Maide! Maide!
I'm in trouble with selecting an item in a ListView when I use a
SimpleAdapter with my own Item display: here's my code
setListAdapter(categoriesAdapter);
categoriesAdapter.notifyDataSetChanged();
int count = categoriesAdapter.getCount();
final ListView listView = getListView();
for (int i = 0; i count; i++) {
final View view = listView.getChildAt(i);
View categoryLabel = view.findViewById(R.id.category);
final int index = i;
categoryLabel.setOnClickListener(new
View.OnClickListener() {
@Override
public void onClick(View v) {
onListItemClick(listView, view, index,
/* unused */-1);
}
});
}
...
The problem is that final View view = listView.getChildAt(i); returns
null for every child: seams categoriesAdapter.notifyDataSetChanged()
is not a sufficient call to inflate the childs immediately...
What is the solution then? do I have to wait until the draw method is
called?
How is it that SimpleAdapter doesn't include a method shortcut
getChildAt(i) ?
Please, if I'm totally in the wrong direction, just notify me about
it :-)
For more details:
my item layout is the following:
?xml version=1.0 encoding=utf-8?
LinearLayout android:id=@+id/categories_view_item
android:layout_width=fill_parent android:layout_height=fill_parent
xmlns:android=http://schemas.android.com/apk/res/android;

[android-beginners] Re: SimpleAdapter onClick event catching. How to?
I found a way but i don't know if it's the one thought by the design:
override SimpleAdapter.getView() then call the super class
implementation to get the view, then do your specific stuff on it
before returning it.

Zied Hamdi

[android-beginners] Re: Follow up on my Acitivty Lifecycle Question
So I think I have a related question about the Lifecycle, but this is more having to do with the application itself. While I think I understand how the whole Tasks/Stack paradigm is supposed to work, I'm not really seeing that sort of behavior with my application when someone exits then comes back. So if I'm running my application and press 'Home', then go to the tray and select my application again, it ALWAYS starts me up at the (intent.action.MAIN, intent.category.LAUNCHER) Activity. I would expect it to just pick the application up from where it was. Is this not the case? Am I missing some sort of parameters or methods that I need to implement to let the application pickup where it was? Thanks!

[android-beginners] Re: Start Activity With Long Press of Home Key
Ok, when I said replacement I really meant alternative... I don't think my expectations were unrealistic, though I can see how you can think they were when I said replacement. I was expecting to be able to long press the home key and have the activity chooser dialog (or whatever its official name is) ask me whether I wanted to use the alternative application or the default one. Seeing as how the default behavior is not an app I now understand that it is not possible. I still think that not allowing alternative actions when long pressing the home key is too restrictive. I mean, how hard would it have been to make long-pressing the home key use an intent and launch an actual app using a dialog theme instead of an internal dialog? Especially when this is the exact behavior of the short press of the home key... it launches an app based on intents and intent-filters. Thanks for your information. Though I don't agree with your opinions and it the tone of your response seemed a bit condescending (which may have just been misread), the information you provided did help me understand a little more about how Android is set up. On Aug 1, 5:05 am, Mark Murphy mmur...@commonsware.com wrote: Everything I read said that essentially any part of the phone could be replaced. First, most likely what you read refers to the fact that Android is open source, and so you can build your own firmware and deploy it on your own devices with whatever changes/replacements you want. Even beyond that, SDK applications have a fair bit of control to provide alternatives for built-in capabilities, though there it is providing *alternatives*, not usually outright replacements, and also only where there are appropriate hooks. What you're trying to do is say that, from an end-user application, you want to replace the right-mouse menu when you click on the desktop background of Windows or Linux. Or you're trying to replace the font-picker drop-down list in Microsoft Word or OpenOffice.org. Fine-grained features like that are not necessarily designed to be replaced in isolation without replacing more of the product. You see this with all sorts of applications and platforms. you can't control what happens when you long press? If you are willing to modify the firmware and distribute those modifications, you can change whatever you want. By my reading of the Android source code, you cannot change what happens on a long-press from an SDK application. Since you are on [android-beginners], my assumption is that you are trying to build an SDK application. That is a very poor/disappointing decision by OS designers that really limits the possibilities of the phone You are certainly welcome to your opinion, just as I am welcome to my opinion that your expectations are unrealistic, even for the most open source of projects.

[android-beginners] Re: Change an app
You are right, activity takes more resources than view. But the difference between them is not significant enough for it to be your primary concern. If you only have two screens, then rather than focusing on optimizing memory and CPU, I suggest you make the code as simple as possible. So instead of two views in one activity, your code will be cleaner if your two screens are separated into two activities.

For example, an activity might present a list of menu items users can choose from or it might display photographs along with their captions. A text messaging application might have one activity that shows a list of contacts to send messages to, a second activity to write the message to the chosen contact, and other activities to review old messages or change settings. Though they work together to form a cohesive user interface, each activity is independent of the others. Each one is implemented as a subclass of the Activity base class.

[android-beginners] Adding objects to a canvas

I am new to the android developing world and have what I think is a
very simple question. I have created a circle on a canvas and drawn it
successfully. I now wish to add another circle to this already
existing canvas in a different position. I have defined my x and y as
arguments I pass to custom drawable view but when I try and get
another circle drawn it just replaces the one that was already
present. How do I keep the first circle and add on a second?
(My code below does not show trying to add another circle, it is
simply what works with creating a single colour circle).

[android-beginners] Custom View blocking other views in layout
I have my own custom view and a few buttons/textviews in a single relativetlayout as follows: /relativelayout textview / customView / /relativelayout The custom view's width and height are set to wrap_content, and I draw my image onto the canvas returned by onDraw. The problem is I see only the image of my custom view and not the textview. I guess it's because the canvas is the size of the whole screen, so even though the view is set to wrap content, it actually takes up the whole screen, thus blocking any other views. How can I make it so custom view takes only as much space as my image? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: Adding objects to a canvas
The onDraw() function is the phone's way of asking you so how do you
want me to draw this canvas, from scratch? If you say draw a circle
there!, you get one circle. If you want it to draw two circles, your
CustomDrawableView needs to tell it to draw two different circles
every time onDraw() is called, for example with two different
drawables.

Hi,
I am new to the android developing world and have what I think is a
very simple question. I have created a circle on a canvas and drawn it
successfully. I now wish to add another circle to this already
existing canvas in a different position. I have defined my x and y as
arguments I pass to custom drawable view but when I try and get
another circle drawn it just replaces the one that was already
present. How do I keep the first circle and add on a second?
(My code below does not show trying to add another circle, it is
simply what works with creating a single colour circle).

[android-beginners] Re: text colour
Do you want to change the color of the TextView items in the list view? In that case use: http://developer.android.com/reference/android/widget/TextView.html#attr_android:textColor To change the divider color use http://developer.android.com/reference/android/widget/ListView.html#attr_android:divider There are programmatic alternatives to these if you want to change colors at runtime.

[android-beginners] Using Intent on default Google Map
I launch the default google map apk from my application, by starting the intent new Intent(Intent.ACTION_VIEW, Uri.parse(geo:+lon+,+lat)), 3); What I want is to start the map with menu option my location clicked and the current address displayed on the sign (user normally can bring up the sign with its address with a long click on the map.) There is a Google application called places directory which can trigger a similar function on Google map, i.e. start the google map with my location with a sign that says You are here The source code for this application is not available, so I can't check what intent it uses to trigger this action. Any suggestions are welcome. If possible tell me where i can get the source code for default google maps... because i cant find out from git repository Thanks, Guna --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

I've got an unlocked t-mobile g1 and it works fine without the sim.

I got it unlocked directly from t-mobile (a friend sold it to me since he was getting the new g2), if you like I can try installing an app into it using eclipse and let you know.

Hi I would suggest using the Hessian protocol, if you have the choice. it is a very light-weight binary web service protocol, optimized for mobile clients - see http://hessian.caucho.com/.
