AlertDialog PositiveButton and NegativeButton trouble

I use below code to show folder list in AlertDialog:

ListDialog = new AlertDialog.Builder(MyActivity.this);
ListDialog.setTitle("Folder List");
ListView folder = new ListView(MyActivity.this);
//scan folder
folder.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
//scan sub-folder
});
ListDialog.setPositiveButton("Save", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
//do something
}
});
ListDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
//back
}
});

I want to make the AlertDialog's NegativeButton always show, and the AlertDialog's PositiveButton only show while the list item number is 0. How to arrive it?

try this, it work fine..

Call Dialog Method Like this,,,,

dialog_message("Dialog msg");


public void dialog_message(String msg) 
    {
          final AlertDialog alertDialog = new AlertDialog.Builder(BottomMenu_Event.this).create();

              alertDialog.setTitle("Title");
              alertDialog.setIcon(R.drawable.icon);
              alertDialog.setMessage(msg);

              alertDialog.setButton("Save", new DialogInterface.OnClickListener()
              {

               public void onClick(DialogInterface dialog, int which) 
               {
                  //Your Code....           
               }
              });

              alertDialog.setButton2("Cancel", new DialogInterface.OnClickListener() 
              {

               public void onClick(DialogInterface dialog, int which) 
               {       

                   alertDialog.dismiss();

               }
              });

              alertDialog.show();

    }

Put condition, if your list item gives 0 then then allow to show positive button else not.

I tried using flag when its not true its wont show positive button else it will show both.

Below is the code

AlertDialog.Builder ListDialog;
     AlertDialog contactMessage;
    flag=true;
    ListDialog = new AlertDialog.Builder(AdvancedListViewActivity.this);
    ListDialog.setTitle("Folder List");
    if(flag!=true){
    ListDialog.setPositiveButton("Save", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface arg0, int arg1) {
    //do something
    }
    });
    }
    ListDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface arg0, int arg1) {
    //back
    }
    });

    contactMessage = ListDialog.create();
    contactMessage.show();

Same thing you can also do, check condition while your list item is not zero avoid positive button else show it.
