Android Jump to Address book to get the user name and mobile phone number of the implementation of ideas _android

The effect diagram looks like this:

First of all, let's say to realize Android jump to the Address Book realization idea:

1. Click to jump to the Address Book interface

2. Get Address Book name and cell phone number

3. Callback display name and cell phone number

1 first jump to the Address Book interface

Uri uri = uri.parse ("Content://contacts/people");
Intent Intent = new Intent (Intent.action_pick, URI);
Startactivityforresult (Intent, 0);

By setting the Address Book URL jump, you can see that we use the callback function to implement

2. Callback function

 /* The callback function of the Jump contact list * * *
 /@Override protected void Onactivityresult (int requestcode, int resultcode, Intent data) {
  switch (requestcode) {case
   0:
    if (data==null)
    {return
     ;
    }
    Processes the returned data, gets the selected contact information
    Uri uri=data.getdata ();
    String[] Contacts=getphonecontacts (URI);
    Et_name.settext (Contacts[0]);
    Et_tele.settext (Contacts[1]);
    break;
  Super.onactivityresult (Requestcode, ResultCode, data);
 }

Where the Getphonecontacts (URI) method, because the phone's contact and cell phone number are no longer in the same database, so we need to do separate processing

 private string[] Getphonecontacts (Uri uri) {string[] contact=new string[2];
  Get Contentresolver object Contentresolver cr = Getcontentresolver ();
  Gets the cursor Cursor cursor=cr.query (uri,null,null,null,null) in the beginning of the phone book;
   if (cursor!=null) {Cursor.movetofirst ();
   Get Contact name int Namefieldcolumnindex=cursor.getcolumnindex (ContactsContract.Contacts.DISPLAY_NAME);
   Contact[0]=cursor.getstring (Namefieldcolumnindex);
   Get phone number String ContactID = cursor.getstring (Cursor.getcolumnindex (contactscontract.contacts._id));
     Cursor phone = cr.query (ContactsContract.CommonDataKinds.Phone.CONTENT_URI, NULL,
   ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactID, NULL, NULL);
    if (phone!= null) {Phone.movetofirst ();
   CONTACT[1] = phone.getstring (Phone.getcolumnindex (ContactsContract.CommonDataKinds.Phone.NUMBER));
   } phone.close ();
  Cursor.close ();
  else {return null;
 return to contact; }

3. Additional Privileges

<!--get Address Book permissions-->
<uses-permission android:name= "Android.permission.READ_CONTACTS"/>
< Uses-permission android:name= "Android.permission.READ_PHONE_STATE"/>
