android studio listview does not go to the end of phone

Before we look at how to code this, let’s take a look at the steps involved in creating this type of ListView. We’ll request that the data is returned as a JSON string and we’ll decode the JSON using the very useful and easy to use GSON library. To do this, we’ll make use of Async tasks to make the request to the Web API, so that we don’t block the main UI thread. Finally, we’ll lazily load the images for each item in the List as they are needed.Secondly, the data for the feed will be retrieved.

First, we’ll create a ListView with an empty data set.In this example, we are going to build a ListView that loads data from the Picasa web API and displays it in list. Let’s take a look at an example so that we can explore some of these concepts. To do this, they’ll commonly use a REST Web Service, where requests are made using HTTP messages and responses are returned as serialized objects, commonly in an XML or JSON format. Often, applications will display this data in a List. All of these applications will load data at runtime from a server. Have a think about some of the apps you might use, news reading apps, social media, TV guides, and so on. In a lot of cases, ListViews need to display sets of dynamic data that are loaded at runtime.
