如何在应用Android上列出所有移动联系人

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

private List<String> getContacts() {
    List<String> contactsList = new ArrayList<>();

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

    if (cursor != null && cursor.getCount() > 0) {
        while (cursor.moveToNext()) {
            String contactName = cursor.getString(cursor.getColumnIndex(
                    ContactsContract.Contacts.DISPLAY_NAME
            ));
            contactsList.add(contactName);
        }
        cursor.close();
    }

    return contactsList;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    List<String> contacts = getContacts();
    // 在这里可以使用contacts列表进行进一步处理，例如显示在RecyclerView中
}
