How do I pass two variables to the onclick parameter? Only send the data of the fields filled by email using PHP

You must instantiate inflater . Try to fit this line at the beginning of getView() method:

inflater = activity.getLayoutInflater();

You'll need to get a replacement for the activity variable that effectively brings the Activity, perhaps passing it as an argument in the builder of your adapter. Unfortunately I can not remember right how you do it on Android. Good luck.
