Возобновление состояния диалогов при нажатии кнопки «Назад»

Мне нужно иметь дело с Alert Dialog в приложении для Android. В моем первом действии есть одно диалоговое окно предупреждения. В частности, появляется диалоговое окно с предупреждением. Когда пользователь нажимает кнопку «Да» диалогового окна «Предупреждение», пользователь переходит к второму действию. В моем втором упражнении у меня есть одна кнопка. При нажатии этой кнопки в диалоговом окне Alert Dialog снова появляется запрос с таким же состоянием. Возможно ли возобновить нажатие кнопки «Активировать оповещение по обратной ссылке»? Код для диалога ...Возобновление состояния диалогов при нажатии кнопки «Назад»

если ваш вопрос возможно, Тогда это да.

EDIT

Вот пример кода, это может помочь вам.

В вашей деятельности A1: создайте Method из dialog и передайте параметр Контекст, который понадобится во втором действии, чтобы показать, что Dialog. Смотрите, что

public void dialogActivity(final Context c ,int dvalue){ 
    if(dvalue==1){ 
    AlertDialog.Builder builder1 = new AlertDialog.Builder(c); 
    builder1.setMessage("Please fill all the fields"); 
    builder1.setCancelable(true); 
    builder1.setPositiveButton("ok", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      Intent i = new Intent(c, A2.class); 
     startActivity(i); 
      dialog.dismiss(); 
       } 
    }); 

    AlertDialog alert11 = builder1.create(); 
    alert11.show(); 
    } 
    else{ 
    AlertDialog.Builder builder12 = new AlertDialog.Builder(c); 
    builder12.setMessage("Please fill all the fields"); 
    builder12.setCancelable(true); 
    builder12.setPositiveButton("ok", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      Intent i = new Intent(c, A2.class); 
     startActivity(i); 
      dialog.dismiss(); 
       } 
    }); 

    AlertDialog alert12 = builder12.create(); 
    alert11.show(); 

    }

Теперь называют это Dialog метода, где вы хотите, здесь я зову его на backPressed

@Override 
public void onBackPressed() { 
     dialogActivity(A1.this,1); 
}

Тогда в вашей второй деятельности Вы должны создать объект активность А А потом ты могут использовать эту функцию:

A1 ma = new A1();

Затем на спине прессованные Activity вы можете позвонить в диалоговое окно.

@Override 
public void onBackPressed() { 

    ma.dialogActivity(A2.this,1); 
}

FYI: Вызывающая деятельность A2 сама по себе может показать ошибку. Но вот как вы можете добиться диалогового окна в разных действиях.

как? означает, что я должен показать это из второй активности. Средство, диалоговое окно предупреждения находится в 1-й активности, и я должен показать его со второй. –

В 1-ом действии появляется диалоговое окно с предупреждением, после нажатия кнопки «Да» диалога пользователь переходит к второму действию. теперь есть одна кнопка во втором действии, говорят «Назад». когда пользователь нажимает эту кнопку «Назад», диалоговое окно предупреждения должно снова запрашивать. –

сделать функцию alertbox с контекстом в качестве параметра, а затем вызвать эту функцию в любом месте любого класса –

попробовать эту функцию

@Override 
public void onBackPressed() { 

    showAlertDialog(); 

}

showAlertDialog()

private void showAlertDialog() { 
    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(CheckOutScreenActivity.this); 

    // set title 
    alertDialogBuilder.setTitle("Confirmation"); 

    // set dialog message 
    alertDialogBuilder.setMessage("Message").setCancelable(false).setPositiveButton("Yes", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 

     } 
    }).setNegativeButton("No", new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      dialog.cancel(); 
     } 
    }); 

    // create alert dialog 
    AlertDialog alertDialog = alertDialogBuilder.create(); 

    // show it 
    alertDialog.show(); 
}

. Мне нужно отобразить диалоговое окно Alert из кнопки возврата Second Activity. –

В 1-м действии появляется диалоговое окно с предупреждением, после нажатия кнопки «Да» диалога пользователь переходит к второму действию. теперь есть одна кнопка во втором действии, говорят «Назад». когда пользователь нажимает эту кнопку «Назад», диалоговое окно предупреждения должно снова запрашивать. –

Напишите функцию public showAlertDialog() в первом действии и вызовите эту функцию из onBackPressed() второго действия. – mdDroid
