Content providers (get contact information and insert contacts)

A. Get contact information

Click to get contact information

public void Click (View view) {
Get Content Parser
Contentresolver resolver = Getcontentresolver ();
Set the URI of the access (System native)
Uri uri = uri.parse ("content://com.android.contacts/raw_contacts");//ID of the contact
Uri Datauri = Uri.parse ("Content://com.android.contacts/data");//Contact information
Query the ID of all contacts
Cursor idcursor = Resolver.query (URI, new string[]{"contact_id"}, NULL, NULL, NULL);
while (Idcursor.movetonext ()) {
String id = idcursor.getstring (0);
Go to data table by ID
Note: When querying the data is actually a view of the query, in the view of the field mimetype_id changed to MimeType, in the query when the attention to change
Cursor Datacurcor = Resolver.query (Datauri, New string[]{"MimeType", "Data1"}, "Raw_contact_id=?", New String[]{id}, NULL);
Contacts C = new contact ();//declare and instantiate a person information object
while (Datacurcor.movetonext ()) {
String type = datacurcor.getstring (0);
String data = datacurcor.getstring (1);

Encapsulates a contact's specific information based on the value of MimeType
if ("Vnd.android.cursor.item/email_v2". Equals (Type))
C.setemail (data);
if ("Vnd.android.cursor.item/im". Equals (Type))
C.SETQQ (data);
if ("Vnd.android.cursor.item/phone_v2". Equals (Type))
C.setphone (data);
if ("Vnd.android.cursor.item/name". Equals (Type))
C.setname (data);
if ("Vnd.android.cursor.item/postal-address_v2". Equals (Type))
C.setaddress (data);
}
Datacurcor.close ();
List.add (c);
}
Idcursor.close ();
Data Encapsulation Complete

Display in ListView

Lv.setadapter (New Myadapter ());
}
Private class Myadapter extends baseadapter{

@Override
public int GetCount () {
return List.size ();
}

@Override
Public Object getItem (int position) {
return null;
}

@Override
public long getitemid (int position) {
return 0;
}

@Override
Public View GetView (int position, View Convertview, ViewGroup parent) {
TextView TV = null;
if (Convertview = = null)
TV = new TextView (mainactivity.this);
Else
TV = (TextView) Convertview;

Tv.settextsize (15);
StringBuilder sb = new StringBuilder ();
Contact C = list.get (position);
Sb.append ("Name:" + c.getname () + "Phone:" + c.getphone () + "Address:" + c.getaddress () + "Email:" + c.getemail () + "QQ:" + c.getqq ()) ;
Tv.settext (Sb.tostring ());
return TV;
}
}

Note: To read contact permissions in the manifest file, configure permissions

two , Insert a contact information

public void Click (View view) {
Get the information
String name = Etname.gettext (). toString ();
String phone = Etphone.gettext (). toString ();
String email = etemail.gettext (). toString ();

if (textutils.isempty (name) | | Textutils.isempty (phone)
|| Textutils.isempty (email)) {
Toast.maketext (This, "All information must be filled in", 0). Show ();
Return
}

/**
* Idea of inserting data:
* 1. Query the number of records in the Raw_contact table
* 2. Add 1 to the number is the ID of the new record.
3. Inserting records into the data table
*/

Get Content Parser
Contentresolver resolver = Getcontentresolver ();
Set the URI of the access
Uri uri = uri.parse ("content://com.android.contacts/raw_contacts");
Uri Datauri = Uri.parse ("Content://com.android.contacts/data");
Query the ID of all contacts//Get the number of all records

Cursor idcursor = Resolver.query (URI, new string[] {"contact_id"},
NULL, NULL, NULL);
int count = Idcursor.getcount ();
Idcursor.close ();
ID of the inserted record
int id = count + 1;
Insert ID to Raw_contact
Contentvalues values = new Contentvalues ();
Values.put ("contact_id", id);
Resolver.insert (URI, values); The ID is inserted into the table raw_contact.

Inserting data into the database table
Insert Name Record
Contentvalues namevalues = new Contentvalues ();
Namevalues.put ("MimeType", "vnd.android.cursor.item/name");
Namevalues.put ("Data1", name);
Namevalues.put ("raw_contact_id", id);
Resolver.insert (Datauri, namevalues);

Insert Phone
Contentvalues phonevalues = new Contentvalues ();
Phonevalues.put ("MimeType", "vnd.android.cursor.item/phone_v2");
Phonevalues.put ("Data1", phone);
Phonevalues.put ("raw_contact_id", id);
Resolver.insert (Datauri, phonevalues);

Insert Mailbox
Contentvalues emailvalues = new Contentvalues ();
Emailvalues.put ("MimeType", "vnd.android.cursor.item/email_v2");
Emailvalues.put ("data1", email);
Emailvalues.put ("raw_contact_id", id);
Resolver.insert (Datauri, emailvalues);

Toast.maketext (This, "Insert succeeded", 0). Show ();
}
