Android :: Scroll To The New Added Item In ListView
May 7, 2010
My application show a ListView with a button which allow user to add an element. When the user clicks on this button, another Activity is started to allow user to populate the new element. When the add is finished, we return to the previous Activity with the ListView and I would like to scroll to the new element.
Note that this element is not necessarily at the end of the ListView because there is an "order by" when I retrieve the datas from the database. I know I need the cursor position of the new element to make the ListView scrool to it, but the only info I have about this element is its id, so how to convert this id to cursor position ? Do I have to loop on the cursor to find the position?

I have a background color applied to a ListView but everytime the list is scrolled the background color changes back to the system default (black). When the scrolling stops the color goes back to @color/window_background.The style is applied in AndroidManifest.xml:<activity android:name=".event.EventList" android:theme="@style/CKButtons"></activity> and my ListView looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
><ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/android:list"/>
<TextView
android:id="@+id/android:empty"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="@string/eventlist_no_items"/>
</LinearLayout>How can I prevent this from happening?

I am currently using a modified Gallery widget to display real-time events coverflow-style. What I now need is some Method to scroll to a specific item within the Gallery. Such method IS available within frameworks/base/core/java/android/ widget/Gallery.java as scrollToChild but is declared as private. Do you know of any manual way to move/scroll around a Gallery / List Widget?
Current workaround would be to inject DPAD_RIGHT using the Instrumentation Framework, which is as really ugly solution.

I'm sure this is an obvious one but I'm at a loss. I'm using my own layout for list rows, all well and fine. but the moment I add a checkbox view to the rows layout only the checkbox responds to user selection. I'd like for the checkbox to change state if the user taps anywhere within a given row. (as with android prefs)

I was curious if there was a way that I can assign each menu item in a ListView its ID from the SQLite database, so that when I do something like onClick, or using a ContextMenu, I can tell what item / row I am referencing to.

- 2 input boxes where the user can enter criteria to search for - 1 search button - when the search button is clicked, a search is performed and on the same page the matches are shown *below* the 2 input boxes and search button. - the results can be quite a few (say up to 50), which won't fit all on the viewable part of the screen, so the user has to be able to scroll down in the results. - when the user scrolls down over the results, the 2 input boxes + search button should of course also scroll up out of sight.
Basically the behaviour you get when you for example do a google search on google.com. But, for clarity: I don't want to use the WebView. Note that there should be no scrollbar for the results only (that can be done easily with a standard ListView), the all needs to scroll as a whole. The reason I want this behavior is that I don't want to direct the user to a next screen with the search results; that would be so annoying having to go back to the "search" screen all the time if you want to enter another search criteria, like if you figured out you made a typo.............................

I would like to catch horizontal scrolling in ListView. I don't wont to scroll ListView content, I need an event only. I use GestureDetector, and in onScroll() method I can figure out when user scrolls in horizontal direction. This part works. But my problem is ListView fires onItemLongClick event also. I need this event, but only if user doesn't scroll. If user scrolls in vertical direction, ListView doesn't fire onItemLongClick event. I need the same behavior for horizontal scrolling also.

I'm trying to scroll the ListView up/down actions by pressing a button, instead of using finger gesture. It looks like the super class AbsListView.onTouchEvent(MotionEvent ev) handles all the scrolling up/down motion and animation. So if I want to scroll the list by pressing a button, I don't really have a MotionEvent to pass onto onTouchEvent method for it to work. I tried ListView.scrollTo(x,y), it kind of works but the hidden part of the ListView is not rendered when shown on the screen. I am trying to re-draw the list by using: ListView.invalidate(), ListView.invalidateViews(), list.adapter.notifyDataSetChanged()

What I have now is a layout that includes a list view at the bottom. All of the items in the layout above the list view remain fixed as you scroll through the list view. I would like the entire page to scroll so for example when you reached the bottom of the list you would no longer see the items above the list view.

I have a listview displaying my data.Ok. I want to set the scroll position in a position of my choice, but I just cant do it. I used :
myListView.setSelection( anyPosition ); myListView.setSelected(true); and has not worked. I also tried : myListView.scrollTo(0, PositionY); and myListView.scroolBy(0, PositionY);
and there's a strange behavior, this two methods doesn't put the scrool in the "PositionY", it made the "PositionY" be the first position in the list, cutting everything that exist before.

I have an issues, I want to show 20 items in the list.
But there is a catch: if the user scrolls down to the bottom of the list, there will be an item that says: "Show more items", and when the users click on it, more items will be added to the list.
My question is how is poosible to have a last item, that has a different style and looks different: and does different things,(I think this is used in QuickSearchbox)
