I have issue with spanish characters in java string. I have a content
RSS feed and when i try to transform it to java object using
InputStreamReader, I get outputs like cómo which should be cómo.
This is happening with other spanish characters like
á = á é = é í = à ó = ó ú = ú
and more..
Thank you. Will try this.

I am sure this is easy, but can't find solution for this.
My app structure is something like this:
HomeActivity subActivity subSubActivity subSubSubActivity
On each activity (except home) in top left corner I have Home Icon
which creates new Intent and starts home activity with StartActivity.
I would like to have onZoomListener on my MapView.
The code below is what I have done. It registers if zoom buttons are
tapped. Since all new phones now supports pinch to zoom, this is
useless. Does anybody have idea how to do real onZoomListener? Thanks.
OnZoomListener listener = new
I had to subclass MapView and override dispatchDraw
Here is the code:
int oldZoomLevel=-1;
@Override
public void dispatchDraw(Canvas canvas) {
super.dispatchDraw(canvas);
if (getZoomLevel() != oldZoomLevel) {
I am working on an Android app that already exists on iPhone.
In the app, there is a Map activity that has (I counted) around 800
markers in four groups marked by drawable in four different colors.
Each group can be turned on or off. Information about markers I have
inside List. I create a
You are right about populate() calls. I've picked up implementation of
ItemizedOverlay from some online example and didn't question its
validity. Now, when I pay attention, It makes sense what you said.
The posted code is run only when user touch an option to do so.
Thanks a lot TreKing...

Kostya, I tried to do as you suggested. and non of it worked.

doesn't achieve what I want to do.
I would like to add it to the parent that holds list view items. I
have parent available in adapter's GetView method. When I tried to

Thanks anyway.

I would like to add Top Margin on the first item in the ListView. Is
that possible? Or, how can I reference first list item in the List
View?
I tried
lv = (ListView)getListView();
View myRowItem = lv.getChildAt(0);
This probably doesn't work because at the moment I executed it, list
items
Can you please explain how to add topMargin to listView item at
position 0?
For example, I can add topPadding on first item using parameter
position. Test if position is equal 0, add padding, if not, remove
padding. (I sort of not like this, but it seems it is the only way)
The thing is, I cannot

case, set android:paddingBottom on the header view.

I thought about that. But, then another question come to my mind.
Why wouldn't I always use SharedPreferences to save my activity state?
For example:
I passed groupID and itemID values into activity. In onCreate, I save
both values to SharedPreferences.
Latter, when activity is restarted (for any

I've look at logs and my app is crashing because my RowID value is

Here is my onResume method that handle this data that comes from

saving them to SharedPreferences.
In my app at some point I am making oAuth request to authorize user
with Twitter. App opens WebView in which user enter his credentials.
Upon user pressing Allow button, twitter sends Intent (which
contains token and secret) back to my app so user can start when he/
she left of. The problem is my
I have added a view to the header of my ListView by following way:
ListView lv = (ListView)getListView();
View TopSearch = (View) View.inflate(this, R.layout.search,

And everything is fine until I make changes to data

I tried another approach. I defined my RelativeLayout in XML exactly
the way I liked it. Then I used inflater and dynamically added my

It didn't work. It simply ignored all my XML settings. For example,
it fully filled the parent (ScrollView) even though I explicitly

Not sure I understand. My RelativeLayout is enclosed in ScrollView and
