How to flip the checked status of a Switch only after confirm dialog?

Question

My problem is - when I click on a <Switch>, it gets toggled first and then the OnCheckedChangeListener is called.

What I would like is this:

<Switch> is clicked --> I show an AlertDialog --> If pressed yes or no --> Then flip ` with setChecked(boolean), [boolean = true if pressed yes, and false if pressed no].

Problem: When <Switch> is clicked, it gets flipped automatically. I want to qualify it with a yes or no from a AlertDialog first.

Try this code. It worked for me:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // ...
    Switch switchButton = (Switch) findViewById(R.id.my_switch_id);

    switchButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            final Switch btn = (Switch) v;
            final boolean switchChecked = btn.isChecked();

            if (btn.isChecked()) {
                btn.setChecked(false);
            } else {
                btn.setChecked(true);
            }

            String message = "Are you sure you want to disable this setting?";
            if (!btn.isChecked()) {
                message = "Are you sure you want to enable this setting?";
            }
            AlertDialog.Builder builder = new AlertDialog.Builder(this); // Change "this" to `getActivity()` if you're using this on a fragment
            builder.setMessage(message)
                   .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int i) {
                            // "Yes" button was clicked
                            if (switchChecked) {
                                btn.setChecked(true);
                            } else {
                                btn.setChecked(false);
                            }
                        }
                    })
                   .setNegativeButton("Cancel", null)
                   .show();
        }
    });
