Page curl animation to flip between views of a viewflipper - android

I've come across several examples of the page curl animation as well as viewflippers . Is it possible to navigate between children of a viewflipper via a page curl animation . The animations i have applied to viewflippers till now were very basic such as a slide-in/slide-out and I was wondering if the same could be done/has already be implemented using a page-curl animation.


There is an open source android project here: http://code.google.com/p/android-page-curl/.
I found another one here: https://github.com/harism/android_page_curl/.
But there is no native implementation if that is what you are asking.


You need to import one module library for this, from HERE
After that use following code:-

Above code results as like this, (This is not fit to screen height, also have scrolling option, I want 6 cards should fit to screen size)
I want to have like this(all cards equals according to screen size)
NB: These cards should be randomly generated using BaseAdapter or RecyclerAdapter

You can set the number of rows and columns of your GridLayout inside your xml file

Not being able to place an onClickListener on the Grid Items provided by a custom BaseAdapter

If you need any more information I will gladly provided.
I can mention that I've tried placing listeners both in the adapter and in the fragment directly on the grid.

please try this
viewHolder.imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//do stuff
}
});

I am able to see the custom list but while trying to call the function buyTicket with the click of button my app get closed.
Any help will be appreciated.
Edit: The problem was that the method is not passed a view:
public void buyTicket(View view) { ....... }
This solve the above problem but now how to uniquely know which button from the list is clicked.

#Override
public View getView(int position, View convertView, ViewGroup parent) {

if(convertView==null)
convertView = layoutInflater.inflate(R.layout.list_row,null);
TextView title = (TextView)convertView.findViewById(R.id.title);
Button buyTicketButton = (Button)convertView.findViewById(R.id.buyTicket);
Movie m = movieList.get(position);
title.setText(m.getMovieTitle());
buyTicketButton.setOnClickListener(new OnClickListener(){
//..... your code goes here
});
return convertView;
}

You can craete an Button Click event in the Adapter's getView() method.
Button btnBookTicket = (Button)convertView.findViewById(R.id.buyTicket);
btnBookTicket.setOnClickListener(new View.OnClickListener()
{
((MainACtivity)activity).buyMovieTicket();
});

cant get sections to work in contact app/listview

I've been through every stack discussion on this I could find, along with about a dozen tutorials. I'm just not getting it. I'm using 'getItemViewType' to determine which layout I should use. Here's where I run into a problem (and maybe the way I'm getting the position is the root issue, not sure):
What I'm doing is getting the first character of the contact's name at position x. If it's different than the first character in position x-1, I know that it's the next letter in the list and it needs a section header, which would be inserted ABOVE the current list item. How do I get my adapter to add a new layout in position x-1?
This is my adapter code. I've stripped the code which was causing the app to force close, which leaves me with just the 1 layout. I can't figure out how to insert the 'section' layout at position x-1. Below the adapter code I threw in the xml for my 2 layouts. Let me know if you need anything else. Thanks in advance.

I've looked at a bunch of tutorials that ended up confusing me more than helping me, but I found this one to be great. If you've been around the world on this like I have, take a look at this tutorial :)
