Getting Text from Edittext Another Layout

Getting Text from Edittext Another Layout

I have many layouts, but i just want to take the strings from several
different layouts. My problem is what i got is just null....
Here is my code :
LayoutInflater factory = getLayoutInflater();
View input = factory.inflate(R.layout.activity_inputan, null);
View coordinate = factory.inflate(R.layout.activity_location, null);
View scan = factory.inflate(R.layout.activity_scan, null);
EditText prod = (EditText) input.findViewById(R.id.product);
EditText bran = (EditText) input.findViewById(R.id.brand);
EditText plac = (EditText) input.findViewById(R.id.place);
EditText date = (EditText) input.findViewById(R.id.date);
EditText pric = (EditText) input.findViewById(R.id.price);
EditText lat = (EditText) coordinate.findViewById(R.id.latitude);
EditText longi = (EditText) coordinate.findViewById(R.id.longitude);
EditText format = (EditText) scan.findViewById(R.id.format);
EditText content = (EditText) scan.findViewById(R.id.content);
String a = prod.getText().toString();
String b = bran.getText().toString();
String c = plac.getText().toString();
String d = date.getText().toString();
String e = pric.getText().toString();
String f = lat.getText().toString();
String g = longi.getText().toString();
String h = format.getText().toString();
String i = content.getText().toString();
I tried to show it in another layout through a toast, but it's null. Any
help or advices appreciated.
