Hi,
I have a listview showing contacts.
When I'm scrolling the list the scroll works pretty smooth however
when/if I'm trying to continue the scroll in the middle of the last
scrolling the scroll just stops and sometimes the item I clicked on is
selected (I have registered an OnClickListener to the item view).
I would like to get smooth scrolling just as in the device native
contact list.
My implementation builds each contact a view containing:
1. Big picture for the contact image.
2. Small picture for the type of the contact.
3. TextView with the Contact name
4. TextView with some extra text about that contact.
My current layout for every item looks like:
<LinearLayout >
<ImageView />
<LinearLayout/>
<LinearLayout/>
<ImageView />
<TextView/>
</LinearLayout>
<TextView/>
</LinearLayout>
</LinearLayout>
I've tried changing the LinearLayouts to relative ones but saw no
improvement in performance.
I've created my own "Selector" in code (to eliminate the time it takes
to load the resource) so that odd rows will have different background
color. The code looks like:
StateListDrawable draw = new StateListDrawable();
draw.addState(new int[] {android.R.attr.state_selected},
mSelectedRowDrawable);
draw.addState(new int[] {-99},mOddRowBG);
draw.addState(new int[] {},mRowBG);
view.setBackgroundDrawable(draw);
I'll be glad to give more details if needed.
Thanks for the help.
