Auto-complete spinner in android

I have got an edit text where I want that when someon开发者_StackOverflow中文版e insert her values it will narrow his option's . the options are stored in a DB (up to 1200 values to one editbox ).

i cant get the concept of how to do it can someone help me.

Use a AutoCompleteTextView...You'll need a Cursor Adapter for it.

Here's an example

If you need to enter multiple Values into the textbox, use a MultiAutoCompleteTextView...Works with Tokens.

Hope it helps!
