Android Contacts fuzzy query search (number, name, initial spelling, all-in-one), bulk select contacts

The company's recent projects encountered a need to read contact contacts, and need to support the contact of Fuzzy query and batch selection, the Internet to find a few examples, fuzzy query this piece of processing is a little flaw, Finally, I have made the optimization on the basis of the hard contribution of the netizens, and finally make a fuzzy query of the contact person. The following features are supported:

1. By number, name, the first letter simple spell, the whole puzzle fuzzy query
2. Support [A-z] Quick navigation
3. Support Contacts by first letter category
4. Support contact Batch selection.
