EDIT2:
Использование
fragTransaction.add(fragment, tag);
вместо
fragTransaction.add(id, fragment);
OR
Удаление всех фрагментов кода в MainActivity заставляет приложение снова работать по какой-то странной причине.
Получение текста через .getText().toString()
возвращает ноль / пусто при нажатии кнопки.
Пытался вручную .setText("something")
, работает, когда вызывается .getText().toString()
, но,
при изменении текста, вызов .getText().toString()
все равно вернет "что-то".
MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragTransaction = fragmentManager.beginTransaction();
Fragment loginFrag = new LoginFragment();
fragTransaction.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out);
fragTransaction.add(R.id.mainFrag, loginFrag);
fragTransaction.commit();
}
