Question

I have a ListView and a EditText. How can I filter ListView data when typing on EditText?

Answer 1

You can use:

http://developer.android.com/reference/android/widget/TextView.html

addTextChangedListener( TextWatcher watcher )

to figure out when the textview was changed. I believe it should be called everytime a letter is added or removed.

Then update your list adapter to dislplay the new items by either:

1. creating a new list adapter and populating it with the items that satisfy the filter or
2. having a subclass of the BaseAdapter to accept your filter and call notifyDataSetChanged() after it has finished removing the items you no longer want
