Thread: Can't understand where should I use longpress in my code.

Hi. basically I just made a drum pad app, but I can't figure out how to use a longpress or whatever to be able to turn on/off some buttons ( each is playing different music so all I need is to tap once ( to activate ) and the second tap should turn it off )

package com.example.niko.drumpad;
 
import android.media.AudioManager;
import android.media.SoundPool;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
 
public class MainActivity extends AppCompatActivity {
    private SoundPool sp;
    private int sound1;
    private int sound2;
    private int sound3;
    private int sound4;
    private int sound5;
    private int sound6;
    private int sound7;
    private int sound8;
    private int sound9;
    private int sound00;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        sp = new SoundPool(9, AudioManager.STREAM_MUSIC,0);
        sound1 = sp.load(getApplicationContext(),R.raw.sound1,1);
        sound2 = sp.load(getApplicationContext(),R.raw.sound2,1);
        sound3 = sp.load(getApplicationContext(),R.raw.sound3,1);
        sound4 = sp.load(getApplicationContext(),R.raw.sound4,1);
        sound5 = sp.load(getApplicationContext(),R.raw.sound5,1);
        sound6 = sp.load(getApplicationContext(),R.raw.sound6,1);
        sound7 = sp.load(getApplicationContext(),R.raw.sound7,1);
        sound8 = sp.load(getApplicationContext(),R.raw.sound8,1);
        sound9 = sp.load(getApplicationContext(),R.raw.sound9,1);
        sound00 = sp.load(getApplicationContext(),R.raw.sound00,1);
 
    }
 
    public void playsound1(View v){sp.play(sound1,1.0f,1.0f,0,0,1.0f);}
    public void playsound2(View v){sp.play(sound2,1.0f,1.0f,0,0,1.0f);}
    public void playsound3(View v){sp.play(sound3,1.0f,1.0f,0,0,1.0f);}
    public void playsound4(View v){sp.play(sound4,1.0f,1.0f,0,0,1.0f);}
    public void playsound5(View v){sp.play(sound5,1.0f,1.0f,0,0,1.0f);}
    public void playsound6(View v){sp.play(sound6,1.0f,1.0f,0,0,1.0f);}
    public void playsound7(View v){sp.play(sound7,1.0f,1.0f,0,0,1.0f);}
    public void playsound8(View v){sp.play(sound8,1.0f,1.0f,0,0,1.0f);}
    public void playsound9(View v){sp.play(sound9,1.0f,1.0f,0,0,1.0f);}
}

As a beginner - unfortunately no. There is no sample code for drum pad that includes longlick..

What projects was you creating as a beginner ? Seems like I am choosing hard ones.

Alright thanks sir!
