Как показать alertdialog перед запуском asynctask

Question

Я хочу показать alertdialog и получить некоторый ввод от пользователя, а после этого обработать входные данные в asynctask, но alertdialog будет отклонен, прежде чем получить входные данные и запустить асинтекс.

Что мне делать? Пожалуйста, помогите мне. Вот мой код;

private String[] newspapers,newspapersUrl,newspapersPath; 
private String[] choosed,choosedUrl,choosedPath; 
private boolean[] checked; 

private int perNewspaper; 
private boolean returned = false; 

private AlertDialog.Builder builder; 


private FetchingNewsByChoice fetchingNewsByChoice; 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    returned = AlertDialogCreation(); 

    if(returned) 
    { 
     fetchingNewsByChoice = new FetchingNewsByChoice((AppCompatActivity)MainActivity.this,choosed,choosedPath,perNewspaper); 
     fetchingNewsByChoice.execute(); 
    } 


    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) 
        .setAction("Action", null).show(); 
     } 
    }); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.menu_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 

    //noinspection SimplifiableIfStatement

     return true;

Я полагаю, у вас есть setpositivebutton click listenener. Начните свою асинктаску в этом слушателе с нужным входом.

Answer 2

1. Сначала Напишите свою собственную функцию с параметрами.
2. Задайте задачу async внутри этой функции.
3. Теперь вызовите эту функцию, передав значения формы в качестве параметров этой функции после того, как вы закончите сглаживание диалогового окна.
