I am having a custom list view. In general it shows some 5-6 data depending to the data. i want a small message in the end of a ListView saying "End of list of results". How to achieve that?
Use addFooterView method of ListView.
I'm using Android Studio, and I have a listView that musts display an important amount of items. showing all of these items have a huge impact on performances. SO I would like to show them 10 by 10, and with a button show the 10 next items. After some researches, I found this android How to limit list items display in ListView and a button show more and this How to limit list items display in ListView by 10 and next 10after clicking next button. But these didn't lead me to a success. The 1st link looks easier but I didn't know where to put the code samples to make it work. Thanks for help !
You dont need to show "Load More" Button always. You can use Android's Recycler View for this. It will load only the data which can be shown on screen. Rest of the data will be loaded as you scroll down. And the view which is scrolled up (Vanishing views) are recycled automatically.

First link question have a simple answer, If you made a custom adapter for populating listview then there will be a getCount() method which will return the number of items you want to show on listview. if you have not getCount() method then simply override it.

there i(variable) have that value which number if items you want to show on listview, on refresh button click increment the value of i(variable) that will again refresh the whole listview and add the total number of items in listview which is the value of i(variable)

I display first 20 records fetched from server in a listview.
I have baseadapter which is binded to listview as an adapter, and i pass records fetched from server to this baseadapter.
I set a footer item as textview attached to listview, onclicklistener of same, it fetches new 20 records from server, then i add those 20 records and pass to baseadapter.
But it reloads whole listview again, and displays all 40 records but starting from list item 1.
I want to display whole list but cursor point should be from new items added in list, as similar to "Email application" in android.
In other words, only new items should be refreshed to
For that you need to call the below code when you notify your adapter.
listview.setSelectionFromTop();
It set your item from the top.
Your app can keep current listview position and after updting listview you can navigate to this position through setPosition method
I am getting XML data from url and displaying using a custom list adapter in a ListView.
I need to display only 10 items in ListView.
How i can do this?
Please let me know
Thanks
Only put 10 items in the adapter. Or override getCount() and return 10.
The adapter you're using with the ListView only displays the item you put in it.
Just put in your adapter 10 items, or whatever other number you want, and it will display only that items.
