废话就不多说了，主要用到了ContentProvider的相关知识。
//这是一个工具类，主要是将联系人的Name，phone ，email，address，放到List集合中。
package com.example.contact_content_provider;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.provider.ContactsContract;
public class ContactUtils
{
public static List<Map<String, Object>> getContactList(ContentResolver resolver)
{
List<Map<String, Object>>list=new ArrayList<Map<String,Object>>();
//对应表 raw_contacts
String contactUriStr="content://com.android.contacts/raw_contacts";//帮助理解
Uri contactUri=ContactsContract.Contacts.CONTENT_URI;
//对应data表
String dataUriStr="content://com.android.contacts/data";
//联系人电话
String phoneUriStr="content://com.android.contacts/data/phones";
Uri phoneUri=ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
//联系人email;
String emailUriStr="content://com.android.contacts/data/emails";
Uri emailUri=ContactsContract.CommonDataKinds.Email.CONTENT_URI;
//联系人的地址：
String addressUriStr="content://com.android.contacts/data/postals";
Uri addressUri=ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI;
Cursor contactCursor=resolver.query(contactUri, new String []{"_id","display_name"}, null, null, null);
while (contactCursor.moveToNext())
{
int contactId=contactCursor.getInt(0);
String display_name=contactCursor.getString(1);
Map<String , Object>map=new HashMap<String, Object>();
map.put(ContactsContract.Contacts.DISPLAY_NAME,display_name);
map.put(ContactsContract.Contacts._ID, contactId);
//查询联系人电话
Cursor phoneCursor=resolver.query(phoneUri, null, "raw_contact_id=?", new String []{contactId+""}, null);
String phone="";
while(phoneCursor.moveToNext())
{
phone=phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
}
map.put("phone", phone);
//查询联系人的邮箱
Cursor emailcCursor=resolver.query(emailUri, null, "raw_contact_id=?", new String []{contactId+""}, null);
String email="";
while(emailcCursor.moveToNext())
{
email=emailcCursor.getString(emailcCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
map.put("email", email);
Cursor addCursor=resolver.query(addressUri, null, "raw_contact_id=?", new String [] {contactId+""}, null);
String address="";
while(addCursor.moveToNext())
{
address=addCursor.getString(addCursor.getColumnIndex("data1"));
}//上面的ContactsContract.CommonDataKinds.Email.DATA/phone 都可以用data1代替
map.put("address", address);
list.add(map);
}
return list;
}
}

自定义适配器，继承了BaseAdapter。重写里面的四个方法。从而达到自己想要的布局。
这个东西很简单，就不做过多的解释了。
package com.example.contact_content_provider;
import java.util.List;
import java.util.Map;
import android.content.Context;
import android.provider.ContactsContract.Contacts;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
public class MyAdapter extends BaseAdapter
{
ViewHolder holder;
private List<Map<String, Object>>list;
LayoutInflater inflater;
public MyAdapter(Context context,List<Map<String, Object>>list)
{
inflater=LayoutInflater.from(context);
this.list=list;
}
@Override
public int getCount()
{
// TODO Auto-generated method stub
return list.size();
}
@Override
public Object getItem(int arg0)
{
// TODO Auto-generated method stub
return list.get(arg0);
}
@Override
public long getItemId(int arg0)
{
// TODO Auto-generated method stub
return arg0;
}
@Override
public View getView(int arg0, View arg1, ViewGroup arg2)
{
if (arg1==null)
{
holder=new ViewHolder();
arg1=inflater.inflate(R.layout.item, null);
holder.tvname=(TextView)arg1.findViewById(R.id.tv_name);
holder.tvphone=(TextView)arg1.findViewById(R.id.tv_phone);
holder.tvemail=(TextView)arg1.findViewById(R.id.tv_email);
holder.tvaddress=(TextView)arg1.findViewById(R.id.tv_address);
arg1.setTag(holder);
}else {
holder=(ViewHolder)arg1.getTag();
}
holder.tvname.setText(list.get(arg0).get("display_name").toString());
holder.tvphone.setText(list.get(arg0).get("phone").toString());
holder.tvemail.setText(list.get(arg0).get("email").toString());
holder.tvaddress.setText(list.get(arg0).get("address").toString());
return arg1;
}
class ViewHolder
{
TextView tvname,tvphone,tvemail,tvaddress;
}
}

---------------------------------------------------------------------------------------------------------------------
这是联系人的查询显示界面。。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:id="@+id/tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/tv_name"
android:text="address"/>

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/tv_name"
android:layout_alignParentRight="true"
android:text="email"/>
</RelativeLayout>
。还有一点，要对手机里的联系人进行操作，必须要在清单文件中加入两个权限。
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
