comment ajouter des cases à cocher pour afficher la liste dans la boîte de dialogue

Question

J'ai une vue de liste, en cliquant sur l'élément dans la vue de liste je reçois une boîte de dialogue avec la même liste. Maintenant je dois attacher la case à cocher à la liste, et en sélectionnant la case à cocher je dois désactiver l'article. S'il vous plaît aidez-moi à mettre à jour le code et il serait plus appréciable si quelqu'un m'aide en modifiant le code.

MON ACTIVITÉ:

listView1.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { 

       @Override 
       public boolean onItemLongClick(AdapterView<?> parent, View view, 
       int position, long id) { 
       // TODO Auto-generated method stub 
        newListitems2.addAll(itemsList1); 


        dialog = new Dialog(PendingOrdersActitvity.this); 
         dialog.setContentView(R.layout.itembumping); 

         list1=(ListView)dialog.findViewById(R.id.list1); 

         ItemBumpingAdapter adapter2 = new ItemBumpingAdapter(PendingOrdersActitvity.this,newListitems2); 
         list1.setAdapter(adapter2); 
        dialog.show(); 

        return(true); 

       } 


      }); 

MON ADAPTER:

ItemBumpingAdapter public class étend BaseAdapter {

case à cocher xml:

    android:layout_height="wrap_content" 
    android:layout_alignParentRight="true"

Answer 1

Alors d'abord en vous ItemsBean.java ajouter un drapeau pour vérifier que ce point doit être visible ou non.

Supposons que

public class ItemsBean{ 

    //some old variables 
    private boolean isChecked=false; 

    public void setChecked(boolean isChecked){ 
     this.isChecked=isChecked; 
    } 

    public boolean isChecked(){ 
     return isChecked; 
    } 
    } 

maintenant dans getView de ItemBumpingAdapter()

//You have to add checkbox in xml and in ViewHolder. 
//And make sure that newListitems has all ItemsBean.isChecked set to false. 


public View getView(final int position, View convertView, ViewGroup parent) { 
//Your previous implementations 
holder.checkbox.setChecked(false); 
holder.checkbox.settag(position); 
holder.checkbox.setOnClickListener(new OnClickListener(){ 

@Override 
public void onClick(View view){ 
int pos=view.gettag();//Cast object to integer 

    newListitems.get(pos).setChecked(!newListitems.get(pos).isChecked()); 

} 

}); 
return convertView; 
} 

maintenant sur un clic de bouton « Ok » de dialogue, vous devez vérifier isChecked drapeau de newListitems préparer une nouvelle liste de température et mis à CustomAdapter.java adaptateur ou Si vous avez une copie de la liste, puis supprimez checkedbean articles de invoiceDataList et appelez notifyDataStateChanged() de CustomAdapter.
