I have listview in which data is being added dynamically.
When a click of the button, it goes to another activity and listview appears.
I want it to show the last elements of the listview on the click of the button?
How to do it?
You can scroll to bottom of listview by doing following:
listView.setSelection(listAdapter.getCount() - 1);

I've have a listview with some items inside it.
For some of these items, when the users clicks on a button, the buttons is hidden and a status label is showed.
This works fine, but the problem is that the listview scrolls to the top everytime I change the visibility of some item inside a listview.
Any suggestion to avoid this?
I want the listview to stay where it is.
I have a grid view which shows some items. The user can scroll down and up. I want to be able to show a button at the very end of the grid view when the user has scrolled to the end. This button will not show when the user is not at the bottom of the grid. How can this be done ?
When the user is not at the end, the grid should look like this
and upon reaching the end of the gridview, a button should be added as a footer to gridview.
Gridview doesn't allow you to add a footer view but you can program it.
take a look at this answer from Frank.
He has added a scrolllistner and only shows the button when you are getting close to the end.
There is a custom listview in my activity. Each item of list has image button at the left hand side. I want to show popup window when button is clicked. And popup window has some image buttons like chat message.
I want a popup window like when QuickContactBadge is clicked.
How can I do this?
and can I use QuickContactBadge (In list my own contacts not phone's contact)?
Any help....?
You can create a custom dialog by extend a Dialog and putting your own custom View inside it with any buttons that you like.
Update:
I just checked (visually) the QuickContactBadge. The problem in your case will be how to properly position it so that it will so that it will point to the correct listview item that user clicked. Possible solutions:
Put your existing listview layout inside a FrameLayout and put an empty AbsoluteLayout over it. When listview item is clicked, calculate the coordinates and draw
QuickContactBadge in the AbsoluteLayout at the right coordinates so that it would point to the clicked item. Never tried this so I don't know how well this would work:
Use ExpandableListView which expands the item when clicked. In this expaned item you could show the QuickContactBadge or just some buttons that you wish.
Personally, I'd go with 2nd approach.
I added a ListView and a Button to a layout.
What I want to do is, when I click the button, the ListView should scroll to a specified item such as the 10th to the top. But I don't want it to scroll too fast like flipping a page.
How can I do this? Can I add a fraction to a ListView? If so, how can this be archived?
i haven't try it but you can use "setSmoothScrollingEnabled(boolean smoothScrollingEnabled)" method of listview.
i think this will help you.
