我目前正在开发一个Android应用程序，它打算根据用户语音输入调用用户。那是当用户说出一个名字时（即＆＃34; John＆＃34;）。我想从我的联系人列表中检索所有联系人，其中包含该姓名及其联系电话（即＆＃34; John Mavel - + 94715295296，John Cena - +94715295286，Marine Jone - +94715294568，Josh John Samuwel - +94715297895。等＆＃34）。如果只有一个联系人，我想直接打电话而不提出任何建议。到目前为止，我已经实现了一个代码来调用给定的硬编码名称。它需要一个语音输入。

此代码根据联系人姓名检索联系人：
Cursor contactLookupCursor =
getContentResolver().query(
Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
Uri.encode("Rohan")),
new String[] {PhoneLookup.DISPLAY_NAME, PhoneLookup.NUMBER},
null,
null,
null);
try {
while (contactLookupCursor.moveToNext()) {
contactName = contactLookupCursor.getString(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
contactNumber = contactLookupCursor.getString(contactLookupCursor.getColumnIndexOrThrow(PhoneLookup.NUMBER));
}
} finally {
contactLookupCursor.close();
}
希望这有帮助。

好的，试试这个，让我知道发生了什么，
看看 ContactsContract.CommonDataKinds.StructuredName 类。您可以在那里找到您要查找的所有列。
String whereName = ContactsContract.Data.MIMETYPE + " = ?";
String[] whereNameParams = new String[] { ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE };
Cursor nameCur = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, whereName, whereNameParams, ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME);
while (nameCur.moveToNext()) {
String given = nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME));
String family = nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME));
String display = nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME));
}
nameCur.close();
refrence， Look at this question How to get the firstname and lastname from android contacts?

您可以使用此代码找到联系人
String searchName = "john";
String name, number;
String columns[] = new String[] { People.NAME, People.NUMBER };
Uri mContacts = People.CONTENT_URI;
Cursor cur= getContentResolver().query(mContacts, columns, null,null, null);
if (cur.moveToFirst()) {
do {
name = cur.getString(cur.getColumnIndex(People.NAME));
number = cur.getString(cur.getColumnIndex(People.NUMBER));
if((number!=null) && (name.toLowerCase().contains(searchName.toLowerCase()))){
Toast.makeText(this, name, Toast.LENGTH_LONG).show();
// Add Contact to Search array.
}
} while (cur.moveToNext());
}
