How to use Intent putExtra JSON data on android

Question

Recently, in my web server, to get JSON text, I'm using AsyncTask

    String strData = "";

@Override
protected void onPostExecute(String result) {
   super.onPostExecute(result);

final ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1);
try {
    JSONArray arr =new JSONArray(result);
       JSONObject ob = arr.getJSONObject(0);       
       strData += ob.getString("name") + "\n"
               + " - " + ob.getString("school") + "\n"
               + " - " + ob.getString("job") + "\n\n";
       adapter.add(strData);
} catch (JSONException e) {
   Log.d(TAG,"DD");
} 
ListView listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(adapter);
}

result

if you want to send data from json via intent extra try like this `intent.putExtra("information","ob.getString("job")");` — Logic, Aug 29 '16 at 09:29

Parse your Json inside an object of the same structure, then pass that object with the intent

University uni = new University();
uni.setTitle(jsonObj.getJSONObject("Title").opt("val").toString());
Intent i = new Intent(this, anotheractivity.class);
i.putExtra("information", uni);

then you can get your object from the Intent in your other activity

A simple way to get the data in another activity is

To put JSon string in putExtra() and then get the string, parsing it into JSON objects in another activity.

As per your code:

    @Override 
    protected void onPostExecute(String result) {
       super.onPostExecute(result);

    final ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1);
    try { 
        JSONArray arr =new JSONArray(result);
           JSONObject ob = arr.getJSONObject(0);       
           strData += ob.getString("name") + "\n"
                   + " - " + ob.getString("school") + "\n"
                   + " - " + ob.getString("job") + "\n\n";
           adapter.add(strData);
    } catch (JSONException e) {
       Log.d(TAG,"DD");
    }  
    ListView listView = (ListView) findViewById(R.id.listView);
    listView.setAdapter(adapter);
    } 

    you are getting server response in result String, so just put the "result" in Intent as follows:

    Intent intent = new Intent(this, anotheractivity.class);
     intent.putExtra("result","result");
     startActivity(intent);

    In anotheractivity.class onCreate method:
    String result=getIntent().getStringExtra("result");
    Where result contain your JSON data.
