问题 I have a ListView with an OnScrollListener and an OnItemClickListener . When I click on an item, both the onScroll() method in the OnScrollListener and the OnItemClickListener are fired. Is there a way to prevent this behaviour?

问题 I have a listview which gets assigned with different datasets dynamically. This works fine. I have also made fastScrollEnabled to be true. For the sectionIndexer to be updated I need to call list.setFastScrollEnabled(false); list.setFastScrollEnabled(true); The problem is the index shows in top left and this is a know issue.

问题 I have a ListView with an associated ArrayAdapter that displays its contents in several activities. Unfortunately it got necessary now, that my ListView in one of the settings does not display all its elements, but just the ones where "property" is not set to true. I would like to avoid to use two ArrayAdapters with different content, since then I somehow need to keep them in sync. I tried it like this (this method now just assumes that getView is called in the setting where we want to hide
