Text box and list picker

Good morning, I have created a visual dictionary with list pickers from letter a to z. I have entered the search list in each list picker. Each list picker is equivalent to one letter and one to one opens, find the search list at the top and cascade all the words with a. However, if possible, I would like to insert a text box so that the user can search for either a letter or a word a bit like when we do the search with google. Ex: I enter letter m in the textbox and all words with m and so on come out, Thanks in advance for the reply.

Combine all your lists (words a-z) into one list
Use a listview with this:
