Question

Hmm.. I am getting an errors saying the constructor is undefined.

Dele.setOnClickListener(new OnClickListener() {

           public void onClick(View arg0) {



    EditText DelSel = (EditText) findViewById(R.id.ETDeleteSelect);

                   int Id = Integer.parseInt(DelSel.getText().toString());

                   builder = new ***AlertDialog.Builder(this);***
                   builder.setMessage("Are you sure you want to exit?")
                          .setCancelable(false)
                          .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                              public void onClick(DialogInterface dialog, int id) {
                                   MyActivity.this.finish();
                              }
                          })
                          .setNegativeButton("No", new DialogInterface.OnClickListener() {
                              public void onClick(DialogInterface dialog, int id) {

“The constructor AlertDialog.Builder(new View.OnClickListener(){}) is undefined”

What i am trying to do is open a message box when a button is clicked where to continue or not. so someone please help me out.

Replace this with :

builder = new AlertDialog.Builder(YourActivityName.this);

The AlertDialog.Builder constructor expects a Context reference and right now you giving it a OnClickeListener reference(because you’re using this in the anonymous OnClickListener class that you declare as your listener).
