[JAVA] Programming from 51 years old Note: Show multiple views in android dialog / with or without xml

To display multiple views in a dialog, inflate the LinearLayout where the views are placed into the dialog. It's a function I want to use later, so a little memo.

This time, note the dialog that uses layout.xml and the dialog that dynamically generated Layout with new LinearLayout without using layout.xml.

Use Layout / xml (use App / res / layout / --- .xml file)
