This sample app can fetch json from url and show them in list view using built-in Java & Android Methods .


In this app , I have used Java's URL and 

HttpURLConnection

to get Input Stream from given url

and JSONArray

and JSONObjectto fetch JSON .

Procedures:



Give Internet Permission at 

AndroidManifest.xml



android.permission.INTERNET

Create Post Entity »



Post.java



Create A Adapter For List View »



ListAdapter.java


public class ListAdapter extends ArrayAdapter {

    ...



    
Create a inner class JsonFetch.java in 

    

    MainActivity.java which extends AsyncTask.


    private class FetJson extends AsyncTask> {

    ...


    In onPostExecute(..) method , adapter is set for listView .

    

    
Now Execute JsonFetch class inside onCreate method of

     

    MainActivity.java passing url as parameter.


    

    new FetJson().execute("https://jsonplaceholder.typicode.com/posts");





Finally list view shows available data .
