bouton à bascule ne reste pas dans son état

Question

my list view has some toggle button and dates which is to be checked and uncheck on the basis of user choice 
the functionality is to set alarm for those days when button is checked 

when i am clicking the toggle button it sets the alarm for the day 
but when i click next button it overwrite it 
**for ex ... let the user has choice to set alarm for 1, 2 3, 4 or all dates and individual toggle button for this if the user has selected 1, 4,5 then it will work for 5 not for all 
one more issue which i am unable to figure out is when i scroll the list view and the checked button get disappear it automatically sets it unchecked** 

• pour une raison quelconque, je ne peux pas mettre le code

  DDListAdapter public class étend BaseAdapter {

  ArrayList<DataModelDD> listArray;

Answer 1

cela peut vous aider ...

ArrayList<Boolean> toggleOnArr; 
public DDListAdapter(String[] str, String[] str1,ArrayList<Boolean> toggleOnArr) { 
    listArray = new ArrayList<DataModelDD>(); 
    this.toggleOnArr = toggleOnArr; 
    for (int i=0; i < str.length; i++) { 
     listArray.add(new DataModelDD(str[i],str1[i], "Dry Day Alert on " + str[i])); 
    } 


} 

en public Voir getView (position finale int, Vue convertView, parent ViewGroup) l'utilisation de la méthode ci-dessous logique donnée ..

toggleButton.setChecked(toggleOnArr.get(position)); 
toggleButton.setOnClickListener(new View.OnClickListener() { 

    @Override 
    public void onClick(View v) { 
    if(toggleOnArr.get(position)) 
     { 
     toggleOnArr.set(postion,false); //means first this togglebutton was on but you clicked to make it off 

     }else 
     toggleOnArr.set(postion,true); 

    notifyDataSetChanged(); 
} 
});

L'alarme peut être écrasés parce que vous pouvez utiliser le même identifiant pour toutes les alarmes, vous devra garder des identifiants séparés pour chaque date.

Le bouton vérifié se dissapeared parce que le listview obtient rafraîchi. Vous devrez garder l'état des boutons dans un tableau ou par d'autres moyens pour éviter cela.
