	             }
	         }

2. 通过电话号码获得联系人姓名

	 public  String getContactNameByPhoneNumber(Context context, String number) { 

         String[] projection = { ContactsContract.PhoneLookup.DISPLAY_NAME,  
                 ContactsContract.CommonDataKinds.Phone.NUMBER };  
   
         Cursor cursor = context.getContentResolver().query(  
                 ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, ContactsContract.CommonDataKinds.Phone.NUMBER + " = '" + number + "'", null,null);   
         if (cursor == null) {  
             return null;  
         }  
         for (int i = 0; i < cursor.getCount(); i++) {  
             cursor.moveToPosition(i);  
             int nameFieldColumnIndex = cursor  
                     .getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME);  
             String name = cursor.getString(nameFieldColumnIndex);
             int contactid=cursor.getColumnIndex(ContactsContract.Contacts._ID); 
             return name;  
         }  
         return null;  
     }
