Android: ошибка трассировки стека после использования sharedprefs для сеанса входа

1 голос
/ 02 июня 2011

Сначала я хотел, чтобы пользователь вошел в систему, и после входа он не будет возвращаться к экрану входа до выхода из системы.Поэтому я добавил sharedPrefs.Я смог поиграть в логин> mainActivity, а затем выйти из приложения и открыть приложение, которое откроет mainActivity вместо экрана входа в систему.Затем я выйду из системы и вернусь к экрану входа.Как только я нахожусь в экране входа в систему, я выходил из приложения и снова открывал приложение значков, и это выдавало ошибку.Другое дело, когда выход на экран входа в систему и я нажимаю кнопку отмены, это также выдает ошибку.Должно быть, я испортил стек, но не смог найти решение.Я включил logcat ниже, который показывает ту часть, где я больше не мог войти.

Login.java

    //protected static final SharedPreferences settings = null;
    private EditText etUsername;
    private Button btnLogin;

    private String username;

    @Override  
    public boolean onKeyDown(int keyCode, KeyEvent event)  
    {  
        //replaces the default 'Back' button action  
        if(keyCode==KeyEvent.KEYCODE_BACK)  
        {  
            this.startActivity(new Intent(Login.this,Login.class));  
        }  
        return true;  
    }

Итак, ваша проблема в resultsTxt, так как вы не инициализируете его и не пытаетесь вызвать для него метод .setText. Попробуйте инициализировать и проверьте, все ли работает так, как вы хотите.

как: 

resultsTxt = (TextView) findViewById(R.id.**Here select text view where you want to show your result text**);

Счастливого кодирования!

Судя по трассировке, вам нужно иметь представление списка в вашем XML с таким идентификатором:

android:id="@android:id/list"
