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; } }

这是主函数 ，里面的各项操作我已经做了详细的注释。

接下来的是布局文件 ，写的比较简单，也不美观。这种细致的工作有空自己慢慢玩。
这个布局是用来查询和新增联系人。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <Button android:id="@+id/btn_query" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="queryContacts" android:text="查询联系人" /> <Button android:id="@+id/btn_add" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/btn_query" android:onClick="addContacts" android:text="新增联系人" /> <ListView android:id="@+id/lv_showContacts" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/btn_query"></ListView> </RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <Button android:id="@+id/btn_query" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="queryContacts" android:text="查询联系人" /> <Button android:id="@+id/btn_add" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/btn_query" android:onClick="addContacts" android:text="新增联系人" /> <ListView android:id="@+id/lv_showContacts" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/btn_query"></ListView> </RelativeLayout>
---------------------------------------------------------------------------------------------------------------------
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" > <TextView android:id="@+id/tv_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="name"/> <TextView android:id="@+id/tv_phone" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:text="phone"/> <TextView android:id="@+id/tv_address" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/tv_name" android:text="address"/> <TextView android:id="@+id/tv_email" 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"/>
