如何在單聲道中使用多選旋鈕控制器？

-1

我想在單聲道爲android使用多選單元。我想將國家綁定到微調器現在在正常的微調器中有帶單選按鈕的標籤。但我想用複選框標籤。如何在單聲道中使用多選旋鈕控制器？

任何人都可以幫助我。

AlertDialog.Builder alt_bld = new AlertDialog.Builder(
     CareCardActivity.this); 
alt_bld.setTitle("Select Recepients"); 
alt_bld.setMultiChoiceItems(tempname, new boolean[tempname.length] , new DialogInterface.OnMultiChoiceClickListener() { 

    public void onClick(DialogInterface dialog, int which, 
      boolean isChecked) { 
     // TODO Auto-generated method stub 

    } 
}); 
alt_bld.setPositiveButton("Ok", new DialogInterface.OnClickListener() { 

    public void onClick(DialogInterface dialog, int which) { 

     // TODO Auto-generated method stub 
     ListView list = ((AlertDialog) dialog).getListView(); 

     Log.v("LIST COUNT:: ", ""+list.getCount()); 
     for (int i = 0; i < list.getCount(); i++) { 
      boolean checked = list.isItemChecked(i); 

      if (checked) { 
       sb.append(contactNumber[i]).append(";"); 
      } 
     } 
     sb = sb.replace(
       sb.length() - 1, 
       sb.length(), ""); 
     txtPhoneNo.setText(sb.toString()); 
    } 
}); 

alt_bld.setNegativeButton("Cancel", 
     new DialogInterface.OnClickListener() { 

      public void onClick(DialogInterface dialog, int which) { 
       // TODO Auto-generated method stub 

      } 
     }); 

AlertDialog alert = alt_bld.create(); 
alert.show();

我已經試過這個代碼在日食它工作得很好，但我想這樣做的單聲道在C＃開發。

單選按鈕和複選框之間有區別。所以你要求的是一個多選的微調器？另外，stackoverflow是針對您無法工作的特定代碼段中的問題，而不是爲您提供現成的解決方案，因此請添加您在問題中嘗試過的內容。 – Cheesebaron

呼叫按鈕

ShowDialog(DIALOG_MULTIPLE_CHOICE);

添加點擊此功能下面的代碼

protected override Dialog OnCreateDialog(int id) 
    { 
     switch (id) { 
     case DATE_DIALOG_ID: 
      return new DatePickerDialog(this, OnDateSet, date.Year, date.Month - 1, date.Day); 



     case DIALOG_MULTIPLE_CHOICE: { 
      var builder = new AlertDialog.Builder (this); 
      //   builder.SetIcon (Resource.Drawable.ic_popup_reminder); 
      builder.SetTitle ("Select Country"); 
      builder.SetMultiChoiceItems (countryName, new bool[countryName.Length], MultiListClicked); 

      builder.SetPositiveButton ("ok", OkClicked); 
      builder.SetNegativeButton ("Cancel", CancelClicked); 

      return builder.Create(); 
     } 
     } 
     return null; 
    } 
    private void MultiListClicked (object sender, DialogMultiChoiceClickEventArgs e) 
    { 
     Console.WriteLine ("countryMultiListClicked"); 
     if (e.IsChecked) { 
      mSelectedItems.Add (countryName [(int)e.Which]); 
      mSelectedItemsID.Add (countryID [(int)e.Which]); 
     } 
     else if (mSelectedItems.Contains(countryName [(int)e.Which])) 
     { 
      mSelectedItems.Remove(countryName [(int)e.Which]); 
      mSelectedItemsID.Remove(countryID [(int)e.Which]); 
     } 
    } 
    private void OkClicked (object sender, DialogClickEventArgs e) 
    { 
     Console.WriteLine ("countryOkClicked"); 

     String listString = ""; 
     for (int i =0; i<mSelectedItems.Count; i++) { 
      listString += mSelectedItems [i] + ","; 
     } 
     if (listString.Length > 0) { 
      listString = listString.Remove (listString.Length - 1); 
     } 
     et_country.Text = listString; 

     listStringId = ""; 
     for (int i =0; i<mSelectedItemsID.Count; i++) { 
      listStringId += mSelectedItemsID [i] + ","; 
     } 
     if (listStringId.Length > 0) { 
      listStringId = listStringId.Remove (listStringId.Length - 1); 
     } 
     Console.WriteLine (listStringId); 
    } 
    private void CancelClicked (object sender, DialogClickEventArgs e) 
    { 
     Console.WriteLine("countryCancelClicked"); 
    }

這工作得很好........！
