Answer 1

First implement the positive button click listener like this and then you can write your code for ad in that listener

new MaterialDialog.Builder(this)
.onPositive(new MaterialDialog.SingleButtonCallback() {
    @Override
    public void onClick(MaterialDialog dialog, DialogAction which) {
        // here you can write the code for showing ads
    }
})
