如何调用android通讯录？
问题描述：
我正在写一个android应用程序，需要调用手机的通讯录。我需要调用通讯录的功能，选择一个联系人，然后将联系人的名字返回到我的应用程序中。下边是我在网上找的代码，但是不起作用。
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.view.View;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;
public class Contacts extends ListActivity {
private ListAdapter mAdapter;
public TextView pbContact;
public static String PBCONTACT;
public static final int ACTIVITY_EDIT=1;
private static final int ACTIVITY_CREATE=0;
// 当activity第一次创建完成后调用
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
Cursor C = getContentResolver().query(People.CONTENT_URI, null, null, null, null);
startManagingCursor(C);
String[] columns = new String[] {People.NAME};
int[] names = new int[] {R.id.row_entry};
mAdapter = new SimpleCursorAdapter(this, R.layout.mycontacts, C, columns, names);
setListAdapter(mAdapter);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Cursor C = (Cursor) mAdapter.getItem(position);
PBCONTACT = C.getString(C.getColumnIndex(People.NAME));
Intent i = new Intent(this, NoteEdit.class);
startActivityForResult(i, ACTIVITY_CREATE);
}
}

我不能100%的确定你的示例代码应该是做什么的，但是下边的摘要应该能够帮助你调用通讯录的功能，选择一个联系人，然后将你联系人的名字返回到你的app中。
这个过程有三步：
1)
许可
向你的应用程序的manifest中添加读取通讯录数据的许可
<uses-permission android:name="android.permission.READ_CONTACTS"/>
2)
调用Contact Picker
在你的activity中，创建一个Intent，用来请求系统查找一个能够执行一个从Contacts URI的项目中发出的PICK动作的activity，
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
调用startActivityForResult在Intent中传递（和一个整数的请求代码，在这个例子中是PICK_CONTACT ）。这将导致android启动一个已经被等级的activity，用来支持在People.CONTENT_URI上的ACTION_PICK ，然后当按下选择（或者取消）的时候返回到这个activity。
startActivityForResult(intent, PICK_CONTACT);
3)
仍然在你的activity中，重写onActivityResul方法来监听在你的第二个步骤中启动的activi'select a contact' activity的回调。你应该检查反馈的请求代码是否匹配你的期望值，结果代码是否是 RESULT_OK。
通过在数据Intent参数中调用getData()你可以获得选择的联系人的URI。为了获得选择的联系人的名字你需要使用URI从返回的游标中创建一个新的查询和提取的参数。
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode) {
case (PICK_CONTACT) :
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
Cursor c = managedQuery(contactData, null, null, null, null);
if (c.moveToFirst()) {
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
}
break;
}
}

对于android 2.2 Froyo版本我是这样做的：基本上是用eclipse来创建一个类，像：public class SomePickContactName 继承Activity
然后插入这个代码。记得加private类变量和在我的版本代码中被引用的常量
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intentContact, PICK_CONTACT);
}
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
if (requestCode == PICK_CONTACT)
{
getContactInfo(intent);
}
}
protected void getContactInfo(Intent intent)
{
Cursor cursor = managedQuery(intent.getData(), null, null, null, null);
while (cursor.moveToNext())
{
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if ( hasPhone.equalsIgnoreCase("1"))
hasPhone = "true";
else
hasPhone = "false" ;
if (Boolean.parseBoolean(hasPhone))
{
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
while (phones.moveToNext())
{
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);
while (emails.moveToNext())
{
emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emails.close();
Cursor address = getContentResolver().query(
ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + contactId,
null, null);
while (address.moveToNext())
{
poBox = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
street = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
city = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
state = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
postalCode = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
country = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));
type = address.getString(address.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE));
}
}
cursor.close();
