I write this code to fetch data from URL and get the title from each JSON object and show this in the list view. The problem is data is stored successfully in productlist variable, which I check it by Log.d and Toast massage method. but it not show in listview.

```
  public void onResponse(JSONArray response) {
            try {
                    for(int i=0;i<response.length();i++) {
                        JSONObject productfromjson = response.getJSONObject(i);
                        productList.add(productfromjson.getString("title"));
                    }
                    Log.d("products", String.valueOf(productList));
                    Toast.makeText(MainActivity.this, String.valueOf(productList), Toast.LENGTH_SHORT).show();
                } catch (JSONException e) {
                    e.printStackTrace();

                }
        }

```

the following is the adaptor code
ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.simple\_list\_item\_1, productList);
myproducts.setAdapter(arrayAdapter);
