如何使用查找密钥检索android中联系人的详细信息？

<uses-permission android:name="android.permission.READ_CONTACTS" />

ContentResolver contentResolver = getContentResolver();

Cursor cursor = contentResolver.query(
    ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

while (cursor.moveToNext()) {
    String contactId = cursor.getString(cursor.getColumnIndex(
        ContactsContract.Contacts._ID));
    String displayName = cursor.getString(cursor.getColumnIndex(
        ContactsContract.Contacts.DISPLAY_NAME));

    // 获取联系人的电话号码
    Cursor phoneCursor = contentResolver.query(
        ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
        new String[]{contactId}, null);
    while (phoneCursor.moveToNext()) {
        String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(
            ContactsContract.CommonDataKinds.Phone.NUMBER));
        // 处理电话号码
    }
    phoneCursor.close();

    // 获取联系人的电子邮件地址
    Cursor emailCursor = contentResolver.query(
        ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
        ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
        new String[]{contactId}, null);
    while (emailCursor.moveToNext()) {
        String emailAddress = emailCursor.getString(emailCursor.getColumnIndex(
            ContactsContract.CommonDataKinds.Email.ADDRESS));
        // 处理电子邮件地址
    }
    emailCursor.close();

    // 处理其他联系人详细信息
}

cursor.close();
