                List<Ayah> list = new ArrayList<Ayah>(response.body().getQuran().getQuranSimple().values());
                String surah = "";

                for (Ayah ayah: list) {
                    surah += ayah.getSurah() + ":" + ayah.getAyah() + " ";
                    surah += ayah.getVerse() + '\n';
                }
                surah = surah.replace("\n", System.getProperty("line.separator"));
                next.setAdapter(new ArrayAdapter<String>(this, R.id.Sorah, surah.toCharArray()));
            }

            @Override
            public void onFailure(Call<MyResponse> call, Throwable t) {
                TextView tv = (TextView) findViewById(R.id.verse);
                tv.setText("Op Failed");
            }
        });
    }
}
}

set the Adapter and find the ListView inside onCreate . You can add data to it later. — OneCricketeer, Jun 04 '16 at 21:22
Also, you have an `Ayah` class, so extend an `ArrayAdapter` in your own class to make a [custom adapter layout](https://stackoverflow.com/questions/8166497/custom-adapter-for-list-view) — OneCricketeer, Jun 04 '16 at 21:26

Change the setAdapter like this way ->

next.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, surah.toCharArray()));

The problem here you have to use android default item list when you use ArrayAdapter.

Still getting error can't resolve constructor(Arrayadapter annoy namus reterogit2.callback,myclass package name,int,char[]) – Ahsan Raza Jun 04 '16 at 19:18
You can see Surah is my string variable but setadapter gives me error of JAVA.lang,string something like this how can I add this string variable in LIstView?? – Ahsan Raza Jun 04 '16 at 19:20
declare the `next = (ListView) findViewById(R.id.Sorah);` in your activity , not in onClick – Zahidul Islam Jun 04 '16 at 19:20
I think the problem with `this` which should be a context . use `Next.this` instad of `this` as a first parameter of the `ArrayAdapter` – Zahidul Islam Jun 04 '16 at 19:25
Let me make it more simple I want to show String value on screen which is very large as you Know Surah of Quran that so why I am not using textView but is there any way that user can slide textView up or down to read the Full text???? – Ahsan Raza Jun 04 '16 at 19:27
I don't see any problem in your code. Log the size of surah.toCharArray().length , Also can you please post the `sorah` layout ? – Zahidul Islam Jun 04 '16 at 19:35
this is my Sorah layout. – Ahsan Raza Jun 04 '16 at 19:37
Layout is ok, Check the value of `surah.toCharArray().length` – Zahidul Islam Jun 04 '16 at 19:44
This would show one character on each lineitem... Is that really the expected behavior that is wanted? – OneCricketeer Jun 04 '16 at 21:24
