[android-developers] Re: listView get child items in a loop

[Streets Of Boston]

I assume your ListView has a ListAdapter (probably a BaseAdapter?).

In your Adapter's getView(...) method, you have a position parameter. The 
position is the index into your array-list of data that you'd like to show 
in the correct list-item-view. 

You get your data-item from the Adapter given the position 
(getItem(position)).
You create your view, if your convertView is not yet set. In that view you 
have your EditText/TextViews and you assign the data from the data-item to 
these views.
Use the method 'setTag(...)' of your list-item-view and set the data-item 
as the list-item-view's tag.

When you convertView was null, you had to create you list-item-view. When 
creating this, set a TextWatcher to your EditText that allows you to be 
notified when the user changes the text.

In your TextWatcher, get hold of the list-item-view of your EditText. Get 
the tag from the list-item-view (getTag(...) method) and that will be the 
data-item associated with that list-item-view. Update the changed text from 
the EditText in your data-item.

When saving the data to the server, get hold of you Adapter, use getCount() 
and getItem(...) calls to get all the data-items. It should contain the 
updated EditText texts.

Try to print your data using LOG function and try to narrow down problem. 
If your LOG does not print anything it means you are not getting any data 
likewise do this to check functionality that you have implemented and 
figure out where is problem in the code! happy coding !

[android-developers] Re: ListView getCount is wrong - how do I reset it?

[plnelson]

*FIXED:*

I fixed the *getCount()* problem.  After updating the listItems I now call 
*setListAdapter()* on the ListActivity.  (@Streets of Boston - there is 
only one ListActivity).   After that, when I call the ListView's 
*getCount()* it returns the correct value.

*N.B.* that this does *not* fix the other bug I have in a parallel thread - 
getView's position parameter value coming back too big

[android-developers] Re: ListView getCount is wrong - how do I reset it?

[Streets Of Boston]

Debug the listItems (ArrayList of Strings). Monitor its add method(s), i.e. 
set breakpoints on them, and figure out which code adds to this static list 
without notifying the ListAdapter(s).

[android-developers] Re: ListView getCount is wrong - how do I reset it?

[Streets Of Boston]

It's bad programming practice, but you inherited it, so you need to deal 
with it.. :-)

Question, though, and if this applies to your problem, you'll see why it is 
bad practices to make it static.

Your ListActivity, does it have more than one instance? In other words, are 
there more than one ListActivities that access/use this static arraylist of 
Strings?
If so, you, that could be your problem. 

It does matter that the arraylist of strings (listItems) is static. You may 
have more than one ListActivity instances around at any given time, sharing 
the same arraylist (through their ListView's adapters) and this opens a big 
can of worms.
If this is the cause of the issue, then you really should change the 
architecture. If you don't have the authority, tell whomever (didn't) give 
you that authority what the problem is and how you would like to properly 
solve it.

[android-developers] Re: ListView getCount is wrong - how do I reset it?

[plnelson]

I call if after adding each one mostly for diagnostics -  I wanted to see 
in the debugger what changed and when.   That's the same reason I'm getting 
the list items size -  for diagnostics, for debugging this problem.

*It's all for the same question *- How do I get ListView to report its 
correct size in getCount after the the size of its dataset changes?   When 
the size of listItems was 12 the listView's getCount returned 12; After 
I've changed the size of listItems to 6 I expect the ListView's getCount to 
return 6 - how to I get ListView to correctly return its new count?

[android-developers] Re: ListView getCount is wrong - how do I reset it?

[plnelson]

It's public and static because the method in the ListActivity that calls it 
is static.   So if it wasn't static it would generate a compile-time error 
that a static method can't refence a non-static object.   The ListActivity 
method is static is that way because that's how the original program was 
architected and I don't have the authority to change the architecture.

But why does it matter?Why can't the size of a ListView be reset if 
it's static?

[android-developers] Re: ListView getCount is wrong - how do I reset it?

[Rufatet Babakishiyev]

After adding each item to listItems I do a notifyDataSetChanged() on the 
adapter.

Why you call adter adding each time.

public void updateListItems(){
   // TODO clear list
   // TODO Add element to list
   // TODO NOTIFY DATA SET CHANGED
   // TODO try to get list item size (I do not know why you need it)
}

P.S Sure you created adapter with this list and adapter set to list.

Come again? How do you update your UI if not by modifying the adapter data
and notifying it of the change?

Invalidate doesn't do what you think it does.  That has to do with the 
rendering of the view on screen, not the contents of the adapter that the 
ListView knows about.

Try setting a new (non-public, non-static) adapter into the ListView 
instead.

Never change the contents of the data in an adapter after you've given it 
to the ListView.  Make a deep copy of the data before sending it if you 
have to.

[android-developers] Re: ListView vs. GridView vs. TableLayout

[ankit the OPIUM]

Is your designing is something like onClick of an item on First list should 
change content of rest of the column? If yes,you can try Fragments. It will 
be a nice to have 2 fragments in tablet and one in phone.
Just search for fragment tutorials on google you will get tons.

[android-developers] Re: ListView with "selected" state does not work when list item view has a background

[lbendlin]

I would go with the brute force approach. Yes, you're redrawing the 
(visible part of the) list but you're only doing it once, not every five 
milliseconds.

[android-developers] Re: ListView content thread sync cases

[Bill Michaelson]

My confusion has been due to the lack of appreciation that in spite of the 
fact that the server-obtained updates run asynchronously in a Thread 
started by the Service, the initial Service logic is part of the main 
thread which is shared with the Activities.

I had coded the Handler in one of the Activities.  I am moving the Handler 
into the Service.  This is the logical place for the code that fields 
asynchronous updates obtained from the remote location that must be 
interwoven into the functioning of the UI.  The placement satisfies two 
criteria:

   - It is started and ready to operate regardless of the state of the UI.
   - It lives in the UI thread so that no synchronization locking needs to 
   occur,
   
I simply need to provide a mechanism that enables the handler to determine 
which data structures are present and ready for update in the Activities at 
any given time.  This is accomplished by setting/resetting pointers to the 
Activies in onCreate/onDestroy. The communications thread simply needs to 
queue work to it.
Make sense?

That's the point. Those kind of items cause issues though they can be

[android-developers] Re: ListView one item per screen

[Piren]

I'm not saying that you should use the library (since its obviously isnt 
working and you dont want to revert to an older version of it).

I did say that at least to me, it be easier to either write your own 
ViewPager based on their source or make a ViewFlipper (and the likes) work 
as a pager. Trying to retrofit a ListView looks like the harder path to 
take.

[android-developers] Re: ListView checked state wrongly shared between 2 views when reorienting screen

[João Paulo Forny]

Sorry for asking it here, but i have the same problem and some points were 
not clear for me. 

What do you mean by views that don't need to save their state? In my case, 
the problem is with custom views that don't have the same ids, but its 
children do, because it is created from a xml file. I thought of many 
workarounds, like using android:configChanges attribute in the manifest or 
commenting the line that calls the super.onRestoreInstanceState(), but I 
really wanna know if there is a solution for this that is not considered a 
workaround.

Thanks in advance,

Re: [android-developers] Re: ListView doesn't refresh when last item is deleted

[Jacek Jabłoński]

Okay, so after investigating problem a little bit more, I found that this
problem only applies to Android 4.0.x. This bug doesn't exist in 2.2, 2.3
or 4.1, only 4.0. The only way for me to solve this bug is to add to
onLoadFinished()


getListView().setVisibility(View.GONE);

getListView().setVisibility(View.VISIBLE);

I don't find it elegant way, bu maybe you will have some ideas.

Thanks for all answers,

Jacek

For me, even invalidate() doesn't work. It's strange.

[Andrew Mackenzie]

 I've also had problems getting notify to work, and resorted to using 
"invalidate()" (I think that's the name, but which from memory maybe 
deprecated??) and even just detecting that change in my List Activity and 
doing the query for the cursor again.

I'm pretty sure there is a more recommended, elegant, way of doing this 
(notify()!) but I haven't found one yet that works reliably.

 First we thought of putting everything inside a linear layout with

 a scroll view. Then we come to know that it is not a good idea. So
 right now what we are trying to do is
 add header and footer for listview. Header view will be a text view and
 footer view will be a layout which conatins
 a texview and listview. The problem what we are facing now is ,  we are
 not able to scroll the second listview which is in

Re: [android-developers] Re: Listview - Header , footer issue

[Piren]

Maybe i delivered what i meant wrong...
You can still inflate rows predefined using XML, but your the way to create 
the specific inner layout would have to be created manually.

you want to do something like this:

   
  
  
  
  
   


You can't do that in android (well, you can, it just wouldn't work as you 
expect it to).

The best option is to just do:

   


and then "inflate" all the information inside that linear layout. 
Practically making your entire page one ListView (a listview is exactly 
that.. a linear layout inside a scrollview with some fancy wrapper code to 
make your life easier)

Your "adapter" would just have to know how to inflate the "rows" 
differently according to their type.
i.e - the first row is just a regular textview (the header).
the second to X row would be rows of the first "listview" you wanted.
X+1 row is again a textview (the footer) and then X+2 to the end are rows 
of the second listview type.

[android-developers] Re: Listview - Header , footer issue

[Piren]

Android doesn't support putting two scrollable views one inside the other 
and i assume you dont want to divide the screen area between the listviews 
and make each take a constant size.

You're best (and probably only) choice is to just do everything manually. 
put a linear layout inside a scrollview and inflate everything in it 
manually. (the two textviews and the two listviews).
you can actually use the same code you wrote for your listviews to do that 
with some modifications.
It sounds like a lot of effort, but after doing it a few times i've noticed 
that it isnt. in some instances it even makes stuff easier.

[android-developers] Re: ListView | Full Code | Cannot capture item click!

[kj]

Don't set click listeners directly on the items you are creating in 
getView(). Use ListView.setOnItemClickListener() and 
ListView.setOnItemLongClickListener() instead. If you need particular item 
data, the AdapterView given in those callbacks have methods to get items at 
positions from the adapter.

I guess I should have left it in there, but I would have only been able to 
leave one attempt at, anyway, I suppose. 

I reverted to a 'working' build to demonstrate where I was in a working 
state.

Sorry about that.

Thank you for the solution. Linear Layout works as well.

Re: [android-developers] Re: ListView simple_list_item_activated_1 behaviour

[Pankaj Chawla]

Yes, I did and this causes the Multiselect mode CAB to show up. CAB shows up as 
soon as 
setItemChecked is called programmatically if CHOICE_MODE_MULTIPLE_MODAL is set 
for the
listView.

Anyways I went ahead and created a custom ArrayAdapter which keeps all the 
state information about
selection, multiselect etc and then based on the state it does background color 
changes when getView
is called:

public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);

if (!bMultiSelect)
{
if (position == nSelectedPostion)
v.setBackgroundColor(nColor);
else
v.setBackgroundColor(Color.TRANSPARENT);
}
else
{
if (nSelectedPositions[position] == 1)
v.setBackgroundColor(nMultiColor);
else
v.setBackgroundColor(Color.TRANSPARENT);
}
return v;
}

Take care,

[android-developers] Re: ListView simple_list_item_activated_1 behaviour

[Calin Perebiceanu]

Did you tried handling the on list item click ?
 @Override
protected void onListItemClick(ListView l, View v, int position, long 
id) {
// Make the newly clicked item the currently selected one.
getListView().setItemChecked(position, true);
}

In getView(), if you are going to manage colors yourself, you need to
*always* set the *right color*. *You* know what the right color is;
Android does not.

That being said, I question the entire approach that you are taking.

If your ListView is being shown in conjunction with other widgets
(e.g., managed by a fragment), where the content of those other
widgets is determined by what the user tapped on in the ListView, then
the notion of maintaining a highlight is appropriate. This UI pattern
-- what Google refers to as the "master-detail pattern", is
particularly useful on landscape large-screen devices. On Android
3.0+, Android has an "activated" style that you can use to manage the
color for you. On older devices (e.g., you want master-detail on a
Kindle Fire), then you might need to manage this more yourself, using
the techniques that you are trying.

In any other circumstance, I counsel you against doing what you are
doing. For example, it may interfere with those using your app with a
D-pad, trackball, arrow keys, or some other pointing device, as they
need to distinguish which row is selected by the pointing device, so
they know which row will be "clicked" when they, say, press down on
the trackball or on the center D-pad button.

It is me again!!! When I select the first item and then I did everything 
Mr. Mark Murphy said when I scroll down and then come back to the top, the 
first item is black again instead of pink? Is there any way to store this 
option (for example selected=true) and repaint the same object as pink the

   1. If you use your own layout you don't need to set the font size
   programmatically
   2. You don't have to use SimpleCursorAdapter... You can use any adapter
   you want, and it doesn't have to be your own... You can use the stock
   adapters if they suit your needs.

Use Custom adapter.
Implement a class extends BaseAdapter.

Ate you need to change the font size programmatically, you need to use your

That should be fine if you don't have a lot of items or if your views are
kept very simple Otherwise doing this will cause choppiness when
scrolling the listview.

 Hi all,
 I need your help to understand the refresh behaviour of a ListView
 where I've defined a my custom view for the ListView's items.

 I think It's better explain it with an example:
 my adapter contains 7 items: A, B, C, D, E, F, G correctly initialized,
 filled and working. The associated ListView shows 5 (out of 7) items: A, B,
 C, D, E.
 The problem is that, when I scroll down the ListView's content instead
 of showing me items F and G, I've got A and B items again. I understood
 that this is "only" a viewing issue becouse the model elements associated
 with the last two items, correctly belong to F and G items. :|

 Following the ovveride of getView(...) method of my adapter (extending
 BaseAdapter):

 @Override
 public View getView(int position, View convertView, ViewGroup
 parent) {
 MyItemView miv = (( MyItemView  ) convertView);

 if (context == null) return null;

 if (convertView == null) {
 miv = new MyItemView ();
 .
 } else {
 miv.refreshView(); //refresh the view content
 }

 return miv;
 }

 and the refreshView() method of MyItemView (extending LinearLayout):

 @Override
 public void refreshView() {
 label1.setText(..);
 label2.setText(..);
 label2.setText(..);

 invalidate();
 }

 Thanks a lot to all!
 Bye
 Sergio

an example of what is called a view holder to have a performance
improvement.
Also in the Google IO 2010 it is well explain from the developer itself

Interesting…  I usually just create a new View every time in getView…  so 
I've never run into that.

[android-developers] Re: ListView with custom view item refresh issue

[Sergio Panico]

Hi all,
I thank all for your answers.

I've understood the "strange" behaviour that doesn't makes my ListView to 
refreshes correctly.

Here is the link where I've found the solution: 
https://groups.google.com/forum/?fromgroups#!topic/android-developers/2Ub4yhyKumM

This topic clearly explains that, when the callback method "getView" is 
called, the parameter "convertView" is null only when ListView tries to 
draw the first 5 items, from "A" to "E". When I scroll down the content of 
the list, and the ListView draws the items 6 and 7, it "reuses" the views 
previoulsy created, hence "convertView" is not null and my getView 
implementation goes into "else" branch.

What I've missed was to bind the "old" view, with the "new" model item 
getting showed. So the fix was simply to add, in this branch, the update of 
the bind between "recycled" view and model item.

HTH
Sergio

[android-developers] Re: ListView with custom view item refresh issue

[soynerdito soynerdito]

Don't quite understands the situation. But here is a short example if you 
extends from BaseAdapter and implement in the same line. This is using a 
layout called custom_view (copied bellow). This code is from an Activity 
and can be on the onCreate (The activity must have a ListView called 
listView1
Experiment with different Adapters until you find the one that works better 
for you, all do basically the same but may require less code, depending on 
how much flexibility you need.

 ListView list = (ListView)findViewById(R.id.listView1);
   list.setAdapter(new BaseAdapter(){
   private String values[] = new String[] 
{"VALUE1","VALUE2","VALUE3","VALUE4","VALUE5",
   "VALUE6", "VALUE7" }; 
   
public int getCount() {
return values.length;
}

public Object getItem(int position) {
return values[position];
}

public long getItemId(int position) {
return position;
}

public View getView(int position, View convertView, ViewGroup 
parent) {
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.custom_view,null);
TextView tvLine1 = (TextView)view.findViewById(R.id.textView1);
TextView tvLine2 = (TextView)view.findViewById(R.id.textView2);
tvLine1.setText(values[position]);
tvLine2.setText("Line2" + values[position]);
return view;
}
   
   });


*File: custom_view.xml*

[android-developers] Re: ListView with custom view item refresh issue

[bob]

 

Sure sounds like a bug in getView.  Make sure getView works when 
position==5 and position==6.

[android-developers] Re: ListView - Expandable items and scrolling

[Tolriq]

Finally after writing my response I think about better search on google :)

And the solution is logical after I put better words on the problem :

listView.post(new Runnable() {

@Override
public void run() {
listView.requestChildRectangleOnScreen(view,
new Rect(0, 0, view.getRight(), 
view.getHeight()), false);
}
});

This will make the scroll happens after the redraw so works with correct 
measures.

[android-developers] Re: ListView inside a tabhost not displaying content initially

[Robert Joly]

I had the exact same setup in my app (multiple tabs using the same ListView 
and had the same issue as you observed).  My initial work-around was to 
quickly switch the tab to 1 and then back to 0 but, the way my app handled 
tab changes, this has some nasty side-effects.  What I ended up doing 
instead is toggling the visibility of the ListView in onStart():
mListView.setVisibility(View.GONE);
mListView.setVisibility(View.VISIBLE);

and that took care of my problem.

Good luck,
bob

Re: [android-developers] Re: ListView with Simple adapter

[imran ali]

Hi, 
why are you doing this 
   View row=super.getView(position, convertView, parent);
 though you are in getView() Method.
so you will get convertView that is same. 

Ok, 
follow this,

if(convertview==null){
1. inflate view,  
2. check type of data and set visibility 
3.set tag of view.

}else{
// getTag value 
}
//set values in fields of view.

hope it will help you.

Regards
Imran Ali

[android-developers] Re: ListView with Simple adapter

[kalandar]

 hi shruthi,
  
I think you are using if condition inside the getView method to 
visible or invisible some buttons.
try if... else condition instead of if , like this

if(condition true)
 {
  button visible;
 }
else
 {
  button false;
 }

it will cure your problem
let me know this will help or not

Regards
kalandar N

[imran ali]

can you post part of code where your doing visible/invisible of buttons.
I think you are doing some mistake in getView(...) method of Adapter.
and it is going to mess on scroll of listview.

Thanks.  I ended up wrapping the Drawable in a custom View. It wasn't
hard and I can control the appearance with custom attributes, which is
very nice.

I haven't done anyting like what you are trying before but my best guess 
would be to create your own custom view overriding onDraw().

Set them as background objects for some views that appear in your item
layouts.

Or use image views and set them as 'src' images (this way you'll have
better control over scaling and clipping).

[android-developers] Re: ListView header/footer problem

[Jason Tian]

I've had a similar problem. And here is my solution:

Put the header/footer in another wrapper layout (e.g. a FrameLayout maybe), 
and set this wrapper to be the header/footer.

Hope it works.

AbsListView already supports all you need to perform row filtering: it
creates temp TextView that displays filter constraint, delays actual
filtering etc

"Best" is debatable. If you just need a list of items, one after another, a
LinearLayout should suffice.

I think it's possible. But I have never tried though.

But what I have learnt is that ListView aren't the best way to handle
such an UI.

That should work, provided that item separators are disabled in the list

[android-developers] Re: listview adapter. Recycle bitmap

[IcedNet]

You should look into Romain Guy's 2009/10 Google I/O presentations on
UI -- he is the whip with ListViews/UI.
If you're looking for what I think you're looking to do -- which is
speed up that list view -- he has a view holder pattern that will do
just that.

[android-developers] Re: listview adapter. Recycle bitmap

[Studio LFP]

Based on the code there, you wouldn't have the chance to recycle the bitmap 
as you don't keep a handle to it anywhere.

Then again, if the ListView discards that particular row and you aren't 
retaining any handles to the bitmap, then the bitmap should be scheduled for 
collection by the GC. If you did try to retrieve the view that was holding 
the image from the ListView and it did return it to you, there is a good 
chance the ListView still wants to use it and you would not want to release 
the bitmap.

Is there a reason you are wanting to try to recycle the bitmap?

Also, we are talking about the recycle() function on bitmap and not reusing 
the same bitmap, correct?

My first wild guess is that you might a problem in your onStart or
onResume of the activity which hosts your ListView.

 And you need to make the whole entry clickable. all the buttons by

 I think you have image button and text or what ever inside a linear
 layout or relative layout.
 make sure the container of image button and text (i.e. layout)
 setClickable(true) then you will be oki.

I think you have image button and text or what ever inside a linear

Re: [android-developers] Re: ListView and MotionEvent

[Studio LFP]

The HTC Hero has a little ball that can go any direction. So it will work 
left/right and up/down.

With the keyboard, you should be getting onKeyEvents. Override that and 
watch for different keycodes and events.

http://developer.android.com/reference/android/view/KeyEvent.html

I think disable fields may still be able to receive focus for things like 
copy and paste. Even in desktop OSes, you can usually focus and highlight 
disabled fields for things like copy and paste, but just can't edit or 
activate them.

Try using setVisibility( View.GONE ) if you want windows to be 
non-accessible.

A lot of these questions seem to be not related to Android, are you trying 
to do things cross platform or they just an FYI type of thing? Most (if not 
all) Android devices will usually provide ample control. Even the upcoming 
(a few current) Google TVs that don't have a touch screen (one of the reason 
you would still support touch events for fake touch) will have plenty of 
control mechanisms like keyboard, directional pads, mice and touchpads.

Unless someone else that watches this group can let us know, I'm not sure 
there are any Android devices that work like a Blackberry with only one 
degree of movement type control.

Re: [android-developers] Re: ListView and MotionEvent

[John Goche]

I also noticed that a disabled button can be focused, which could require
having to
design a separate icon. I don't understand the point of this combination: if
a button
is disabled why does android make it possible for it to receive the focus?

John Goche

As a curiosity does it have two way na vigation (just a scrollwheel and no
touchscreen) for navigating up and down
like on the blackberry, so that up and down sometimes also means left and
right, or does it have separate left
and right buttons.

This makes a difference when programming the focusing of events. On a
keyboard we have two degrees of freedom
for navigation but with a single scrollwheel it's only one. If I program for
two degrees of freedom devices with a single
degree of freedom may find some buttons inaccessible if laid out
horizontally.

Any suggestions with this regard?

Yes, it is nice to have an app also work with a keyboard attached to a
tablet.

Also, when I press enter on a listview item nothing happens. I thought it
would generate a mousedown
on the emulator but nothing happens. Do I need to modify my code to listen
for some more events?

Thanks,

John Goche

Re: [android-developers] Re: ListView and MotionEvent

[Studio LFP]

The HTC Hero is fairly old. I keep one around because it's quite slow and if 
I can make something function fast on it, it will run exceptionally well on 
new hardware.

On the tablet you can use both a wired and a Bluetooth mouse (I've used a 
wired mouse and Bluetooth keyboard simultaneously). You shouldn't have to 
worry too much about the mouse as it is considered "fake touch" and just 
acts like a simulated finger event. Check out the "Touchscreen" section at 
this link to understand how to support it:

http://developer.android.com/guide/topics/manifest/uses-feature-element.html#hw-features

What you might want to test out is a tablet or phone with a Bluetooth 
keyboard with directional keys. I've run into a few apps that I wanted to 
use the directional keys on my Bluetooth keyboard and it wouldn't function 
properly.  If you plan on doing apps that take a lot of input (like typing 
information in), your users will thank you if you support navigation via the 
keyboard. I'm not fond of having to constantly touch the screen to change 
input boxes when I have a tab and directional keys available.

Some of the specialty hardware, like the Sony Xperia Play, have controls 
that take special consideration. I picked one up to make sure I could test 
things properly on an actual piece of hardware. Some even have special SDK 
add-ons available via Eclipse or from the manufacturers sites. It is one of 
the things that makes Android more challenging to code for, but I personally 
enjoy the challenge. It also gives us, the consumers, a lot of options and 
doesn't force everyone to be the same.

 Just make sure you are catching MotionEvent.ACTION_CANCEL and

 Return false in onTouch to allow it to pass to the Click and LongClick,

Thanks, apparently I was able to get it to work perfectly following your
advice.
What I have not implemented is the code for trackball and joystick devices
which seem to generate their own events as described at:

http://developer.android.com/reference/android/view/MotionEvent.html

Just how old is the HTC Hero and friends which have a trackball?
Do the new tablets take a wired or blutooth keyboard? I find it
interesting that you would wire a blutooth keyboard to a cell phone.

Re: [android-developers] Re: ListView and MotionEvent

[Studio LFP]

An ACTION_CANCEL is sent in the case where the user puts their finger down 
on a ListView item (or similar) and then starts to scroll. Since the 
ListView is using it as a scroll command and your finger may stay inside the 
view, it sends this to cancel the touch on your view.

The ACTION_OUTSIDE would be where a view couldn't or won't scroll and the 
user drags their finger outside the view that received the ACTION_DOWN. 
Computers do the same with mouse events and it gives the user the ability to 
"cancel" a click by holding down and dragging outside of whatever they 
clicked on.

Those two actions are why it is usually recommended to perform an action on 
a mouse/touch/key up instead of down.

Re: [android-developers] Re: listview with images: postInvalidate problems

[John Goche]

Thanks, that works!

 ((SimpleAdapter)
FooActivity.this.listView.getAdapter()).notifyDataSetChanged();

The other function (postInvalidate()) was only refreshing stuff off the
list.

Makes me wonder what use it may have.

Just call:
notifyDataSetChanged()

Notifies the attached View that the
underlying data has been changed
and it should refresh itself.

pskinkhe attached View that the

and it should refresh itself.

Re: [android-developers] Re: ListView: responding to item clicks via a listener

[Streets Of Boston]

Try not to do this. It will break the UI model that Android users expect on 
their phones.
However, if you really need it:

1. Modify the data items that are handled by your ListView's adapter. Add an 
field that could tell how many times a list-item has been clicked (e.g. 
numberOfClicks).

2. Handle the onItemClick(...) (or in your case 'onClick(...)') as follows:
MyDataItem item = adapter.getItem(position);
Increase the item.numberOfClicks. 
If it becomes 1: do nothing.
If it becomes 2: go to the other screen and re-set item.numberOfClicks to 0.
(Be sure to call adapter.notifyDatatSetChanged()).

3. Change the 'getView()' method of your ListView's adapter:
MyDataItem item = getItem(position);
If the corresponding's item.numberOfClicks is 1, then color the background 
of that item in a particular color (that would indicate a 'highlight').
If the corresponding's item.numberOfClicks is not 1, then make the 
background of that item transparent (android.R.color.transparent).

Re: [android-developers] Re: ListView: responding to item clicks via a listener

[John Goche]

Hello,

I am having a slight problem with my approach. When a row is highlighted
orange and
I click on it the orange highlighting goes away. But I want it to stay as I
want taps to

1. highlight the row on the first tap
2. take to a second screen on the second tap

Is this possible?

Thanks,

Well, here is all I have in the file at the moment. Just a bunch of text
views. The idea is that the user can click them
to highlight them and then push a button to take the user to another screen.
How can I improve things
then if that is not the best solution?

[android-developers] Re: ListView: responding to item clicks via a listener

[Streets Of Boston]

The solution you have may work, but it's not the best... keyboard/dpad 
navigation of your list won't work well.

My question is:
What about  R.layout.alarmgroups_item. Could you show the 
alarmgroups_item.xml contents? Maybe one of the items in there is clickable 
and/or focusable.

[android-developers] Re: ListView: responding to item clicks via a listener

[John Goche]

Hello,

The solution was to attach an onItemClick listener to each list item rather
than to the
ListView itself like so:

SimpleAdapter adapter = new SimpleAdapter(this, maps,
R.layout.alarmgroups_item, from, to) {
  @Override
  public View getView(int position, View convertView, ViewGroup parent)
{
View view = super.getView(position, convertView, parent);
// view.setOnClickListener(AlarmGroupsActivity.this);
view.setOnClickListener(new OnClickListener() {

  public void onClick(View arg0) {
Toast.makeText(getApplicationContext(), "clicked",
Toast.LENGTH_SHORT).show();
  }
});
return view;
