View 1 Replies View RelatedAndroid :: ListView And Other Widgets Scroll As Whole
Jul 23, 2009- 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.............................
Android :: Horizontal Scroll In ListView
Mar 26, 2010I 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.
View 2 Replies View RelatedAndroid :: ListView Scroll Up / Down Without Gestures
Nov 5, 2009I'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()

Jul 30, 2010I 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.

View 4 Replies View RelatedAndroid :: Maintaining Scroll Position Of ListView
Apr 7, 2009In my app, my main class extends ListActivity and calls a fillData() function to reload the list whenever changes are made. I'm still getting the hang of this, so I borrowed that concept from the Android Notepadv1-Notepadv3 tutorials. Everything works great, however whenever I need to change the list (remove an item, re-sort it, edit an item), the ListView refreshes and loses its scroll position. The scroll position is reset to the top after each fillData() call.
It appears to be resetting the scroll position to the top because I'm using setListAdapter() each time in fillData(), setting it to a new SimpleCursorAdapter. How can I get the list to "update in place", where the scroll position is seamlessly maintained to the user? I tried heading down the "items.changeCursor(cursor)" path, but that didn't seam to do much for me.......................

View 3 Replies View RelatedAndroid :: Making Child ListView Scroll
Jan 29, 2010I am trying to make a terminal type app that is wider than the actual android screen. A listview is great except that I don't want the text to wrap. If the text is wider than the screen I want it to print the full text and then the user can scroll over horizontally if they want to see what was printed off the screen. Just FYI this is for ascii type tables. I have followed this example:
It works great as far as horizontal text goes it does exactly what I want but I am unable to get the ListView inside the custom LinearLayout to actually scroll veritcally. I have tried passing the Y coordinates from the onScroll method to mListView such as: mListView.scrollBy(0, distanceY); but that seems to move the custom LinearLayout window instead of just scrolling the ListView. I can tell that the ListView is not scrolling because the window moves without the vertical scroll bar of the ListView moving.
Android :: Scroll To The New Added Item In ListView
May 7, 2010My 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?

Android : Get A ListView And TextView To Scroll As One Unit?
Oct 11, 2010I have a main menu screen with a simple ListView that contains "links" to further screens in my app (Browse, Bookmarks, Settings, About, etc.). Underneath the ListView there is a TextView (more accurately, a TextSwitcher that rotates TextViews) that changes every 10 seconds to display a new "tip".
In portrait mode, this works fine. There are my five list items in the ListView , and my tip label underneath. However, when I switch to landscape mode, the ListView is taller than the screen. The ListView scrolls normally, but I cannot scroll past the end of the ListView to see the TextView underneath.
I have tried every possible combination of Layouts, wrappers, ScrollViews, and layout_height parameters and I simply cannot get it to behave.
Here is the simplest code ...
Like I've said, I've already tried so many different combinations that I can't list them, and for the most part I was randomly inserting XML in an attempt to get something to work the way I wanted. So I'd greatly appreciate suggestions as to how I would go about doing this the right way.
Android :: Scroll ListView With Custom Adapter - Too Fast
Aug 4, 2010I have a listview with a custom arrayadapter that handles about 15 strings. The style of each row alternates (between labels and values for those labels--for example row 1 could be "email address" and row 2 would be the actual email address). I'm changing the style of each row to alternate like this in the arrayadapter's getView() method. So if the item at the current position is a label, I'll change the styling from the default row style (which is what the values have applied to them). When the listview first loads, the styling is perfect and just how I want it to be. If I scroll the list slowly up or down, it stays that way. However, if I scroll the list fast up and down, the styling of the value rows starts changing to that of the label ones until all of the rows have the styling of a label row. I've used custom adapters on other listviews in the app with no problems like this. Found out that it also changes all of the rows to the label styling on portrait->landscape orientation changes. Doesn't do this on landscape->portrait changes. Below is the adapter I'm using.
public class DetailsAdapter extends ArrayAdapter<String> { private TextView text = null; private String item = null;
public DetailsAdapter(Context context, int resource, int textViewResourceId, String[] objects) { super(context, resource, textViewResourceId, objects);
} @Override public View getView(int position, View convertView, ViewGroup parent) { text = (TextView) super.getView(position, convertView, parent); item = getItem(position);
if (item.equals("Name") || item.equals("Mobile") || item.equals("Home") || item.equals("Email") || item.equals("Address")) { text.setBackgroundColor(0xFF575757); text.setTextSize(15);
text.setTypeface(null, Typeface.BOLD); text.setPadding(8, 5, 0, 5);
} else { text.setPadding(15, 15, 0, 15); } return text;
} @Override public boolean isEnabled(int position) { item = getItem(position);
if (item.equals("Name") || item.equals("Mobile") || item.equals("Home") || item.equals("Email") || item.equals("Address")) { return false;
} else { return true; } } }

View 1 Replies View RelatedAndroid : Detect Scroll Position Inside A ListView?
Oct 10, 2009I'm building a chat room application where new events are being polled for every X seconds. Every time that happens, this code updates the RoomAdapter (a custom subclass of ArrayAdapter) with the new data and scrolls it to the bottom:
RoomAdapter adapter = (RoomAdapter) getListAdapter();
for (int i=0; i<newEvents.size(); i++)
adapter.add(newEvents.get(i));
getListView().setSelection(events.size()-1);
This is fine, except that if the user is scrolling up to glance at the room's history, it's going to jump her down to the bottom when the poll happens. What I'd like to do is have it so that if the user is already at the bottom of the list, it stays there after a poll for new events. If the user's intentionally scrolled upwards, I'd like the user not to be disturbed.
How do I detect when I'm already scrolled to the bottom of a ListView?
Note: I can't do getListView().getSelectedItemPosition(), because as the docs note, calling setSelection when in touch mode does not actually select the item, just scrolls to it.
Android :: Listview Items Not Redrawn When They Scroll Off Screen In Froyo
Oct 12, 2010I have a listview that when scrolled and the items go off of the screen they are not redrawn when I scroll back to them (the text and checkbox). In fact, items that are off the bottom of the screen in the listview never get drawn when scrolling to them. This only happens in Froyo. Any other version it works just fine. I have checked and the data is there as expected in the adapter when the getItem method is called, it is just not visible. The listview item is there (it's occupying the same amount of screen space per item), I just cannot see the text or checkbox once scrolled off screen and back on again. Code...

Android : Setup ListView Scroll Position Nicely In Droid?
Jul 22, 2010I am aware of setSelection(), setSelectionFromTop(), and setSelectionAfterHeaderView(), but none of them seems to do what I want.
Given an item in the list, I want to scroll so that it is in view. If the item is above the visible window of the list, I want to scroll until the item is the first visible item in the list; if the item is below the visible window, I want it to scroll up until it is the last visible item in the list. If the item is already visible, I don't want any scrolling to occur. How do I go about this?
