这是错误的内容：
【问题讨论】：
【参考方案1】：我想从电话联系人列表（片段内）中获取所选联系人的联系人姓名、号码和电子邮件地址。
这就是你创建意图的方式
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
在哪里：private final int PICK_CONTACT=1;
OnActivtyResult 在下面
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data)
super.onActivityResult(reqCode, resultCode, data);
Toast.makeText(getActivity(),"OnResult fragment called",Toast.LENGTH_LONG).show();
Uri contactData=ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
if(data!=null)
contactData = data.getData();
switch (reqCode)
case PICK_CONTACT:
if (resultCode == Activity.RESULT_OK)
Cursor c = getActivity().getContentResolver().query(contactData, null, null, null, null);
String name="",email="",number="";
if (c.moveToFirst())
String id =c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String hasPhone =c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
//String hasEmail =c.getString(c.getColumnIndex(ContactsContract.Contacts.Data.DATA1.));
if (hasPhone.equalsIgnoreCase("1"))
Cursor phones = getActivity().getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + id,
null, null);
phones.moveToFirst();
number = phones.getString(phones.getColumnIndex("data1"));
phones.close();
Cursor emailCur = getActivity().getContentResolver().query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]id, null);
while (emailCur.moveToNext())
// This would allow you get several email addresses
// if the email addresses were stored in an array
if(emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA))!="")
email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String emailType = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
emailCur.close();
name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
c.close();
setData(name,number,email);
// Do something with the phone number...
不要忘记在父 Activity 中添加它
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data)
super.onActivityResult(reqCode, resultCode, data);
