Question

我当前正在从电话通讯录中选择一个联系人，然后使用以下代码保存姓名：

我想知道是否有一种类似的方式来获取联系人的电子邮件，例如int nameColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME); String name = cursor.getString(nameColumn)

Answer 1

从电话簿中选择联系人

表示您正在使用：

Intent intent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT)

让用户从设备的通讯录应用中选择联系人？

如果是这样，您可以稍微更改选择器代码，使其成为电子邮件选择器：

Intent intent = new Intent(Intent.ACTION_PICK, Email.CONTENT_URI);  
startActivityForResult(intent, PICK_EMAIL);

然后在您的onActivityResult中：

Uri emailUri = data.getData();
Cursor cursor = getContentResolver().query(emailUri, null, null, null, null);
String email = cursor.getString(cursor.getColumnIndex(Email.DATA)); // get the email itself

DatabaseUtils.dumpCursor(cursor); // dump the cursor so you can see the fields and data you can access
cursor.close();
