Querying the contact database 联系人数据库查询

Retrieving Contact Details 获取联系方式

本的联系人信息存储在联系人表中，而详细信息存储在个人表中。在 Android1.x 中查询的联系人记录数据库的URI是People.CONTENT_URI。

package com.test;import android.app.Activity;import android.content.ContentResolver;import android.database.Cursor;import android.os.Bundle;import android.provider.Contacts.People;public class TestContacts extends Activity {    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);               setContentView(R.layout.main);              ContentResolver cr = getContentResolver();               Cursor cur = cr.query(People.CONTENT_URI, null, null, null, null);                if(cur.getCount()>0){                     while (cur.moveToNext()) {                             String id = cur.getString(cur.getColumnIndex(People._ID));                             String name = cur.getString(cur.getColumnIndex(People.DISPLAY_NAME));                      }        }         }}

Phone Numbers 电话号码
查询的URI换成Contacts.Phones.CONTENT_URI。

if (cur.getInt(cur.getColumnIndex(People.PRIMARY_PHONE_ID)) > 0) {                            Cursor pCur = cr.query(Contacts.Phones.CONTENT_URI,null,                            Contacts.Phones.PERSON_ID +" = ?",new String[]{id}, null);         int i=0;                             int pCount = pCur.getCount();                             String[] phoneNum = new String[pCount];                      String[] phoneType = new String[pCount];                     while (pCur.moveToNext()) {             phoneNum[i] = pCur.getString(pCur.getColumnIndex(Contacts.Phones.NUMBER));                    phoneType[i] = pCur.getString(pCur.getColumnIndex(Contacts.Phones.TYPE));                                                         i++;                    }    }

以存储多个电话号码，我们需要遍历返回的结果。查询除了返回电话号码外还返回了其他（家庭，工作，手机等）类型。

Email Addresses 邮件地址

Cursor emailCur = cr.query(Contacts.ContactMethods.CONTENT_EMAIL_URI,null,                        Contacts.ContactMethods.PERSON_ID + " = ?",new String[]{id}, null);                   while (emailCur.moveToNext()) {                     // This would allow you get several email addresses                }                     emailCur.close();

Notes 注释
为每个联系人附加自定义注释。注释存储在联系人记录中，并通过People.NOTES存储的数据进行访问。

String notes=cur.getString(cur.getColumnIndex(People.NOTES));

Postal Addresses 邮政地址
每个联系人都可以存储多个邮政地址。地址存储在联系方式表中，要获取数据，需要有次要条件。添加适配Contacts.ContactMethods.CONTENT_POSTAL_ITEM_TYPE的条件Contacts.ContactMethods.KIND来访问Contacts.ContactMethods.CONTENT_URI传递过来的地址。

String addrWhere = Contacts.ContactMethods.PERSON_ID                 + " = ? AND " + Contacts.ContactMethods.KIND + " = ?";                 String[] addrWhereParams = new String[]{id,                     Contacts.ContactMethods.CONTENT_POSTAL_ITEM_TYPE};                         Cursor addrCur = cr.query(Contacts.ContactMethods.CONTENT_URI,                             null, addrWhere, addrWhereParams, null);                 while(addrCur.moveToNext()) {                    String addr = addrCur.getString(                               addrCur.getColumnIndex(Contacts.ContactMethodsColumns.DATA));                    String type = addrCur.getString(                               addrCur.getColumnIndex(Contacts.ContactMethodsColumns.TYPE));                }                 addrCur.close();
