本文详述了如何在Android 2.2 Froyo中通过Eclipse创建应用，利用Intent ACTION_PICK从ContactsContract获取联系人信息，包括姓名、电话号码、电子邮件地址等，并展示了关键代码段。

在Android2.2 Froyo版本中，我是这样做的：基本上使用Eclipse创建一个类，如：public类SomePickContactName扩展活动

然后插入这段代码。请记住添加在我的代码版本中引用的私有类变量和常量：protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

startActivityForResult(intentContact, PICK_CONTACT);}//onCreatepublic void onActivityResult(int requestCode, int resultCode,

Intent intent) {

if (requestCode == PICK_CONTACT)

{

getContactInfo(intent);

// Your class variables now have the data, so do something with it.

}}//onActivityResultprotected 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();

}

// Find Email Addresses

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())

{

// These are all private class variables, don't forget to create them.

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));

} //address.moveToNext()

} //while (cursor.moveToNext())

cursor.close();}//getContactInfo
