bhavikgarg / JsonFetch

Fetch Json From URL and show them using list view.

This sample app can fetch json from url and show them in list view using Build 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 .
