Question

When a user selects an item to delete, I open an alertDialog to make sure he wants to delete it. When I get the onClick for BUTTON_POSITIVE I need to get the file name to delete. This was known before opening the alertDialog. I tried using setButton(BUTTON_POSITIVE, “Yes”, msg) and set the file name in the message but it is not clear to me where do I get the message? Can someone clarify or propose a better implementation?

Here’s the code that runs after clicking the delete button:

public void OnClick(View v)
{
    Button b = (Button)v;
    CharSequence cs = b.getText();
    int id = Integer.parseInt(cs.toString());

    AlertDialog alertDialog;
    Message msg = new Message();
    msg.arg1 = id;

    AlertDialog deleteAlert = new AlertDialog.Builder(this).create();
    deleteAlert.setTitle("Trigger Remove Alert");
    deleteAlert.setMessage("Are you sure you want to remove this trigger?");
    deleteAlert.setButton(AlertDialog.BUTTON_POSITIVE, "Yes", msg);
    deleteAlert.setButton(AlertDialog.BUTTON_POSITIVE, "Yes", new OnClickListener(){

    @Override
    public void onClick(DialogInterface dialog, int which) {               
    //remove Trigger
        //boolean b = RemoveTriggerPOI(aid, id);
    }
    });
    deleteAlert.setButton2("No", new OnClickListener(){

    @Override
    public void onClick(DialogInterface dialog, int which) {
    //...
    }
    });
    deleteAlert.show();



}

Answer 1

First, define your id or cs as:

final int id = Integer.parseInt(cs.toString());
final CharSequence cs = b.getText();

Now simply use cs and id inside the dialog button’s onClick listener:

 deleteAlert.setButton(AlertDialog.BUTTON_POSITIVE, "Yes", new OnClickListener(){

    @Override
    public void onClick(DialogInterface dialog, int which) {               
       //remove Trigger
       //boolean b = RemoveTriggerPOI(aid, id);

       //SIMPLY USE id OR cs HERE. IT SHOULD WORK
    }
    });
