About Sharedpreferences. Personal understanding of it is understood as a lightweight database. The Access form is the same as map: <key,value>, stored as an XML file.

I just use it to store the login information and login status so that I can read the information locally every time I log in.

A. Storage

/**                             * Save personal information locally *                            /sharedpreferences sharedpreferences = getsharedpreferences ("Intveh", Context.mode_ PRIVATE);                            Sharedpreferences.editor editor = Sharedpreferences.edit ();//Get editor                            //should also record user_id                            editor.putstring (" UserID ", userid);                            Editor.putstring ("Phone", userphone);                            Editor.putstring ("password", userpassword);                            Log Login Status                            editor.putstring ("status", "1");                            Editor.commit ();//Submit Changes

Two. Read

Sharedpreferences sharedpreferences = getsharedpreferences ("Intveh", activity.mode_private);                String userId = sharedpreferences.getstring ("userid", "");                String status = sharedpreferences.getstring ("status", "0");

Please note: sharedpreferences.getstring ("Key", "default value returned when key does not exist").
