Приложение закрывается после закрытия диалогового окна оповещения (застревает в цикле ())

Я пытаюсь создать приложение, в котором вы можете сначала создать событие, которое вы называете с помощью диалога предупреждений.Это событие затем отображается в ListView.Когда вы щелкаете событие в представлении списка, открывается другое действие (ActivityDetailed), в котором отображается подробная информация о событии.В этом действии есть еще один ListView, который отображает разные счетчики.Моя проблема здесь в том, что каждый раз, когда я нажимаю кнопку FloatingActionButton, чтобы создать и присвоить имя новому счетчику, я могу что-то ввести в диалог оповещения, но когда я нажимаю ОК, приложение вылетает.Я уже пробовал отладчик, но он просто застревает в общедоступном статическом цикле void () из класса Looper.

Мой подробный код активности: 

    public class detailedActivity extends AppCompatActivity {

    private String detailName = "";
    private ArrayList<Counter> counterList = new ArrayList<Counter>();
    private Context cntxt = this;
    private int counterId = 0;
    private Handler mainHandler;

    private ListView counterListView;
    private CounterListAdapter counterListAdapter;

    private int eventId = 0;


    public void setDetailName (String pName){
        detailName = pName;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_detailed);
        String[] counterArray = getIntent().getStringArrayExtra("extra_counter");
        for(int i=0; i<counterArray.length; i++){
            String[] args = counterArray[i].split("|");
            counterList.add(new Counter(i, args[0], 1, Integer.valueOf(args[1])));
        }

        eventId = getIntent().getIntExtra("extra_id", 0);

        TextView nameText = (TextView) findViewById(R.id.nameText);
        nameText.setText(getIntent().getStringExtra("extra_name"));

        counterListView = (ListView) findViewById(R.id.counterListView);
        counterListAdapter = new CounterListAdapter(this, counterList);
        counterListView.setAdapter(counterListAdapter);
        FloatingActionButton myFab = (FloatingActionButton) findViewById(R.id.plusCounterFAB);
        myFab.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                AlertDialog.Builder builder = new AlertDialog.Builder(cntxt);
                builder.setTitle("Add a new Counter");
                final View viewInflated = LayoutInflater.from(cntxt).inflate(R.layout.text_input_name, /*(ViewGroup) findViewById(android.R.id.content)*/null, false);
                final EditText input = (EditText) viewInflated.findViewById(R.id.input);
                builder.setView(viewInflated);

                builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        counterList.add(new Counter(counterList.size(), input.getText().toString(), 1, 0));  ////crashes on loop
                        update();
                        if(!detailedActivity.this.isFinishing() && dialog!=null) {
                            dialog.dismiss();
                        }
                    }
                });
                builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.cancel();
                    }
                });

                builder.show();
            }
        });
    }

(игнорируйте часть «NEEDS FIX»), он должен проверить, если вы нажмете кнопку «Назад», а затем перенесете данные в mainActivity)

Мой код mainActivity:

android.content.res.Resources$NotFoundException: String resource ID #0x0

В вашем CounterListAdapter.getView() вы звоните TextView#setText(int), который ожидает идентификатор ресурса.Скорее всего, вместо этого вы хотите вызвать setText(CharSequence) - перед тем как передать его в TextView.

, преобразуйте int в String.
