I have explained the principle of implementing the book paging effect on android and explained how to release the source code at the end of the article. However, there have been a lot of troubles recently, the source code demo originally planned for everyone has no time to complete. It may need to be delay ~~ However, since most of the effects mentioned in the source code implementation principle are only s

Android Get phone Address book contact information Copy Code code as follows: private void Getphonecontacts () { Contentresolver resolver = This.getcontentresolver (); Get Mobile Contact Cursor phonecursor = Resolver.query (Phone.content_uri, New string[] {phone.contact_id, phone.display_name, Phone.number}, Phone.display_name + "=?" + "and" + phone.type + "= '" + Phone.type_mobile + "'"

Android address book read optimization Acceleration 1. When reading the address book at a time, try to read as few attributes as possible, especially when the list is displayed, it will make the loading speed of your list unbearable. We recommend that you load a few attributes first, then, all attributes are loaded at the time of details. 2. When reading a type o

The original intention of writing this example is to imitate the address book list, which achieves some effects and cannot be 100% identical. I think there are still some shortcomings (some memory waste ). This is the first step in this phase. If the amount of code is large, no code will be pasted.
