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.

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.

Android: how to set the number of items in a GridView

I only set the num columns in properties of a GridView. Nowhere to set the number of items
I google but only got some questions about how to fix the rows of GridView. I looking for in API GridView also, but there is no function to do that.
Someone teach me? Thanks

You cannot set the number of items directly on a grid view. This has to be done using its adapter and set the number of items in the adapter.
Usually a variable/array holding the items is created before an adapter is passed to the grid. This will populate the grid accordingly.
To be specific, this is the adapter function
#Override
public int getCount() {
return "HOW MANY ITEMS YOU WANT TO SHOW";
}

If i need to see the data in the ListView Means, i need to scroll down, Can i focus directly to a particular item by any function by passing the position(ID) of the ListView..
For Example this is my ListView that contains 11 items in it..
I'm seeing every time the ListView as the following,..
And my try is, If i give the ListView position as ID=5 means, can i get the Focus of the ListView as follow, in the opening itself...
Can we get this by ListFragment method or anything else?
Suggest me for the Best..

try this, use setselection

Don't know about ListFragment but in listview, you can use listview.setSelection(position);
This method will help you to achieve this
for example: listview.setSelection(5);
