在浪费了超过 3 天之后，找到了做我想做的事情的方法：
common structure 用于存储所有类型的数据，例如电话、地址、电子邮件等。
See the common columns names,
这就是为什么我们无法获取所有类型的数据（联系人、电子邮件、地址
等）具有联系人选择器意图，所以首先我们需要获取联系人
由于联系人选择器意图，ID 或联系人lookUpKey，而不是我们
其他详情需要单独查询。
但是当尝试获取其他详细信息时会出现问题，因为每个
数据保存在相同的表结构中，即可以
持有任何类型的联系数据。
并且存储在给定行中的数据类型由该行的
MIMETYPE 值，它确定通用列的含义
DATA1 到 DATA15。例如，如果数据 Mime 类型是
Phone.CONTENT_ITEM_TYPE，然后DATA1列存储手机
number，但如果数据 Mime 类型为 Email.CONTENT_ITEM_TYPE，则
DATA1 存储电子邮件地址。
所以首先我们需要在查询前设置带有 Mime 类型的 where 子句
任何类型的内容，请参阅 mime 类型列表here
这就是我们应该如何触发一个意图来选择联系人：
int REQUEST_ID_CONTACT_PICKER = 1001;
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(contactPickerIntent, REQUEST_ID_CONTACT_PICKER);
相比onActivityResult，我们在data中获取URI：
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
Contact contact = null;
if (resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case REQUEST_ID_CONTACT_PICKER :
try {
Uri contactURI = intent.getData();
contact = fetchAndBuildContact(getApplicationContext(), contactURI);
Log.d(LOG_TAG, "Pick contact sucessfully!!"+contact.toString());
}
catch (Exception e) {
Log.e(LOG_TAG, "Failed to pick contact!!");
e.printStackTrace();
}
break;
}
} else {
Log.e(LOG_TAG, "Failed to pick contact!!");
}
}
我们不需要查找 LookUpKey，它有助于获取任何 Mime 类型的数据：
private Contact fetchAndBuildContact(Context ctx, Uri uriContact){
// Getting cursorLookUpKey because contacts ID may not be correct all the time.
Cursor cursorLookUpKey = ctx.getContentResolver().query(uriContact, new String[]{ContactsContract.Data.LOOKUP_KEY}, null, null, null);
Contact contact = null;
String lookupKey = null;
if (cursorLookUpKey.moveToFirst()) {
lookupKey = cursorLookUpKey.getString(cursorLookUpKey.getColumnIndex(ContactsContract.Data.LOOKUP_KEY));
if(null != lookupKey ){
contact = new Contact();
contact = buildConactPhoneDetails(lookupKey, ctx, contact);
contact = buildEmailDetails(lookupKey, ctx, contact);
contact = buildAddressDetails(lookupKey, ctx, contact);
}
}
cursorLookUpKey.close();
return contact;
}
这就是我们使用ContactsContract.Data.MIMETYPE = ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE获取电话详细信息的方法：
private Contact buildConactPhoneDetails(String lookupKey, Context ctx, final Contact contact) {
ContentResolver contentResolver = ctx.getContentResolver();
String contactWhere = ContactsContract.Data.LOOKUP_KEY + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] contactWhereParams = new String[]{lookupKey, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE};
Cursor cursorPhone = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, contactWhere, contactWhereParams, null);
if (cursorPhone.getCount() > 0) {
if (cursorPhone.moveToNext()) {
if (Integer.parseInt(cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
String givenName = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String familyName = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME));
String middleName = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.MIDDLE_NAME));
int contactType = cursorPhone.getInt(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
String phoneNo = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contact.contactNumber = phoneNo;
contact.givenName = givenName;
contact.familyName = familyName;
contact.middleName = middleName;
contact.contactType = contactType;
}
}
}
cursorPhone.close();
return contact;
}
这就是我们使用ContactsContract.Data.MIMETYPE = ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE获取电子邮件详细信息的方法：
private Contact buildEmailDetails (String lookupKey, Context ctx, final Contact contact) {
ContentResolver contentResolver = ctx.getContentResolver();
String emailWhere = ContactsContract.Data.LOOKUP_KEY+ " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] emailWhereParams = new String[]{lookupKey, ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE};
Cursor emailCursor = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, emailWhere, emailWhereParams, null);
if (emailCursor.moveToNext()) {
String emailId = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
contact.emailId = emailId;
}
emailCursor.close();
return contact;
}
这就是我们使用ContactsContract.Data.MIMETYPE = ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE获取PhoneDetails的方法：
private Contact buildAddressDetails(String lookupKey, Context ctx, final Contact contact) {
ContentResolver contentResolver = ctx.getContentResolver();
String addrWhere = ContactsContract.Data.LOOKUP_KEY + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] addrWhereParams = new String[]{lookupKey, ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE};
Cursor addrCursor = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, addrWhere, addrWhereParams, null);
if (addrCursor.moveToNext()) {
String poBox = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
String street = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
String city = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
String state = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
String postalCode = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
String country = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));
String neighborhood = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.NEIGHBORHOOD));
String formattedAddress = addrCursor.getString(addrCursor.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS));
contact.poBox = poBox;
contact.street = street;
contact.city = city;
contact.state = state;
contact.zipcode = postalCode;
contact.country = country;
contact.street = street;
contact.neighborhood = neighborhood;
contact.poBox = poBox;
contact.formattedAddress = formattedAddress;
}
addrCursor.close();
return contact;
}
这是 Contact POJO 类，我们在上面的代码中创建：
public class Contact {
String country;
String poBox;
String givenName;
String middleName;
String familyName;
String address;
String city;
String state;
String street;
String zipcode;
String emailId;
String contactNumber;
String neighborhood;
String formattedAddress;
String label;
int contactType;
}
