Consider using AutoCompleteTextView instead of simple EditText.

Have a look at the documentation: developer.android.com/intl/de/reference/android/widget/…

Well, AutoCompleteTextView is meant for such functionality. It looks like EditText, but you can populate it with array of strings (using ArrayAdapter) and drop-down of suggestions will pop up when you will start entering text (exactly as you described).

I tried the sample given in the document,but it doesn't show the string in the dropdown list,what is wrong with it,it simple displays the autocompltetextview box with out string content,please help me

Populating AutoCompleteTextView is very similar to populating ListView or Spinner. Did you set completionThreshold attribute to desired value (1 in your case)? In general, latter problem description is too laconic to really answer what is causing that.
