在最后一个数组中选择数据（android）

我需要帮助来选择最后一个数组中的数据，然后在编辑文本中显示它，这是我的代码：

izinnonfullday.java（主要）

        setContentView(R.layout.activity_izinnonfullday);
        final String nik_baru = getIntent().getStringExtra(KEY_NIK);
        nopengajuan = (EditText) findViewById(R.id.nopengajuan);
        nopengajuan.setFocusable(false);
        no_pengajuan = new ArrayList<>();


        list_data = (Button) findViewById(R.id.list_data);
        list_data.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(izinnonfullday.this, tabel_izin_non_full_day.class);

        spinner.setAdapter(adapter);

                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH, monthOfYear);

                SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
                edittext.setText(sdf.format(myCalendar.getTime()));
            }
        };

                        .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                        myCalendar.get(Calendar.DAY_OF_MONTH)).show();

                                JSONObject obj = new JSONObject(response);
                                JSONArray movieArray = obj.getJSONArray("data");

                                ///get last data only///
                                for (int i = 0; i < movieArray.length(); i++) {
                                        JSONObject movieObject = movieArray.getJSONObject(-1);

                                        postnonfullmodel nomor = new postnonfullmodel(
                                                movieObject.getInt("no_pengajuan_non_full"));

                                        nopengajuan.setText(nomor.getNo_pengajuan_non_full());


                                }

            RequestQueue requestQueue = Volley.newRequestQueue(this);
            requestQueue.add(stringRequest);

        }
    }

postnonfullmodel.java（获取数据）

public class postnonfullmodel {
    Integer no_pengajuan_non_full;

    public postnonfullmodel(Integer no_pengajuan_non_full){
        this.no_pengajuan_non_full = no_pengajuan_non_full;
    }
    public Integer getNo_pengajuan_non_full() {return no_pengajuan_non_full; }
}

我想在pengajuan的edittext中显示数据，这是最后一个数组

你们能解决吗？我很感激...
