[android-developers] Re: UI troubles with Android 2.2
The second trouble is resolved thanks to another message in this google group ( http://groups.google.com/group/android-developers/browse_thread/thread/4e8ad65d5cc7f103/c0986e9ad4e655e2 ). Nested scrollviews don't work anymore. Does anyone have an idea why several click attempts are necessary to open the context menu by clicking on an ImageView (located inside a ListView)?

[android-developers] Re: UI troubles with Android 2.2
Thank you for your answer,
I call setOnClickListener() in the Activity while I create the list of
views. Then i give this list to the adapter. The Adapter::getView()
method just returns the view _list.get(position). See below for code
sample.
But I would like to say that the onclick behavior is very very strange
on that list (although everything works with Android 2.1). The last
item reacts correctly, but the previous ones seem to stack the call
and execute the whole stack as a batch when any action finally
succeeds.
In the Activity:
_listView = new ListView(this);
[ ... ]
PeriodListAdapter adapter = new PeriodListAdapter();
OnClickListener openMenu = new OnClickListener() {
@Override
public void onClick(View v) {
PeriodActivity.this.openContextMenu(v);
}
};
PeriodDescription therapyP = new PeriodDescription(this);
therapyP.setPeriod(p);
therapyP.setOnClickMenu(openMenu);
adapter.addPeriodDescription(therapyP);
[ ... ]
_listView.setAdapter(adapter);
Thanks for your interest
Thibaut, a poor disappointed developer...

Thibaud, Where in your code do you call setOnClickListener() ? Please remember that ListView recycles the views behind each list item. Quick peek at your Adapter.getView() method would help here.

I think you have to work harder on your Adapter.getView().
Have a look at these and then fix your Adapter:
