</RelativeLayout>

При нажатии на любую кнопку издаётся определённый звук. Но мне нужно чтобы кнопка с id: ID_electric_shield, при нажатии издавала звук(уже есть) и при зажатии на 2 секунды издавала другой звук

Используй OnTouchListener. Вот простой пример.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/playButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintRight_toRightOf="parent"/>

</androidx.constraintlayout.widget.ConstraintLayout>

MainActivity.java

import androidx.annotation.RawRes;
import androidx.appcompat.app.AppCompatActivity;

import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;

public class MainActivity extends AppCompatActivity implements View.OnTouchListener {
    private long down;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.playButton).setOnTouchListener(this);
    }

    @Override
    public boolean onTouch(View view, MotionEvent motionEvent) {
        switch (motionEvent.getAction()) {
            case MotionEvent.ACTION_DOWN:
                down = System.currentTimeMillis();
                break;
            case MotionEvent.ACTION_UP:
                if (System.currentTimeMillis() - down < 2000)
                    play(R.raw.sweep);
                else
                    play(R.raw.game_over);
                break;
        }
        return false;
    }

    private void play(@RawRes int soundResource) {
        final MediaPlayer player = MediaPlayer.create(this, soundResource);
        player.start();
    }

Я немного видоизменил код под работу с несколькими кнопками:
