Question

I am stuck,i have a json text file in Sd Card and i need to read a json file from the SD card and display the data in to my textview.

This is my json textfile name is textarabics.json:

{
"data": [
    {
        "id": "1",
        "title": "Farhan Shah",
        "duration": 10,
    },
    {
        "id": "2",
        "title": "Noman Shah",
        "duration": 10,
    },
    {
        "id": "3",
        "title": "Ahmad Shah",
        "duration": 8,
    },
    {

Answer 1

You can do it like this:
1- Read file
2- Take the text and parse it :

JSONObject json = new JSONObject(text);
JSONArray ar = new JSONArray(json.getString("data"));
for (int i = 0; i < ar.length(); i++) {
     try {
          JSONObject jpost = ar.getJSONObject(i);
          // Pulling items from the array
          int id = jpost.getInteger("id");
          String title = jpost.getString("title");
          int duration = jpost.getInteger("duration");
          // DO whatever
          //Ex.
          //textView.setText(title);
          //if you use "Thread", you can put Thread.sleep(duration*1000);
     } catch (JSONException e) {
          // Oops
          e.printStackTrace();
     }
}

hope this helps
Note: You may get Error cause there is comma after duration in your json file
