Android Question SearchView Class - taking too long for indexing.

u2005k · Aug 1, 2014

Hi,

I am trying to use SearchView class, file I am loading is > 2MB and has nearly 100K lines (one item/line). It is working, that is search is quite good however it takes too long to build the index. I don't want to show items with matching string anywhere but only in the beginning. Is there any way I can speed up indexing part of the class? It takes nearly 5 minutes to index the data file.

Thanks & regards...

You can order the large files in alphabetical order and create a file for each letter.
Then, in Sub edittext1_TextChanged (Old As String, New As String)
end Sub
Recognize the first letter and according to that you choose one of the files cut off. +

PS. I'm using google translate, I hope you understand.

If you are only interested in prefix matching then you can make it much faster by modifying SearchView code.

1. Change MAX_LIMIT to 2 or 3.
2. Remote this for loop: For start = 0 To item.Length
Instead create a variable names start and set it to 0.
