Android obtains all text messages from mobile phones.

The principle is that contentprovider obtains the field information in the system SMS database to obtain the content.

As follows:

The Code is as follows:

Package COM. internal. message; import Java. text. simpledateformat; import Java. util. arraylist; import Java. util. date; import Java. util. hashmap; import Java. util. list; import Java. util. map; import android. app. listactivity; import android. content. contentresolver; import android. database. cursor; import android. database.

E ("sqliteexception in getsmsinphone", Ex. getmessage () ;}}/*** use the address mobile phone number to associate the display name of the contacts Contact * @ Param address * @ return */private string getpeoplenamefromperson (string address) {If (address = NULL | Address = "") {return NULL;} string strperson = "null"; string [] projection = new string [] {Phone. display_name, phone. number}; Uri uri_person = Uri. withappendedpath (contactscontract. commondatakinds. phone. content_filter_uri, address); // address mobile phone number filtering cursor = getcontentresolver (). query (uri_person, projection, null); If (cursor. movetofirst () {int index_peoplename = cursor. getcolumnindex (phone. display_name); string strpeoplename = cursor. getstring (index_peoplename); strperson = strpeoplename;} else {strperson = address;} cursor. close (); cursor = NULL; return strperson ;}}

In fact, it is easy to get the database content. I hope it will help you.
