android - User Input saved to new activity -

i'm extremely new android development , i'm decent @ java. i'm working on making first app , i'm stuck @ spot i've researched past 2 days don't know do. want make similar how contacts set in android.

i able create 2 buttons in main activity page , have intent activity click of button(s). when come 2nd activity, want user able "add class" , want take new activity user inputs information such "class name" "assignment type" "assignment worth" etc. , hit save. , doing so, want new class added activity listview item "add class".

but want user able click new item created, example, "math" , when he/she presses it, opens new activity information stored previously. , wondering how go that. thank you.

you want save user's input data persistent storage, eg: shared preferences, sqlite data base or plain text file, go sqlite data base it's suited job. after user saves data he'll return first activity in pull data sqlite data base , load in listview via cursorloader , loadermanager, load data listview asynchronously.

i don't know level of skill suggest start learn android's sqlite, tutorials can found on youtube, this one , cursorloaders this one.
