I had used the above code in my code but didn't anything work. :( :( :( :( :(

What??? Means???

I want full activity of above code

I want to set the toast display time 20 second. How can I set the toast time manually?

I want to make an activity that have one spinner that spinner contain 5 colors name they are as follows, RED,GREEN, BLUE, BLACK, WHITE. And when I select particular color from the spinner, for example I select RED, and if I dispose that activity and again opened it then that spinner must contain the RED color name. How can I make this type of activity? I think sharedPreferances can do it. But I'm new in Android Programming so please any one give me that kind of full activity code.

How to SAVE spinner data and LOAD it inside that spinner.

Any other method except Toast. Because toast doesn't have close or OK button like pop up message box. :(

How can we display the pop up message of some activity? but that activity must have in onPause() state. OR How to display the pop up message of activity in our front screen, smiler like flash message had been displayed on our front screen. But activity must have in onPause() mode.

I have used the above code in my activity but nothing append anything. :( Can you give me the activity? Cause I am new in Android. And What is "key, value_obtained_from_spinner"? Cause I have created the the spinner programmatically.

How save spinner data using sharedPreferences and How that data load in that spinner after reopening of the activity?
