Verifizieren von zufälligen Notizen in Android

Question

Ich habe ein Array, das eine zufällige Note wählt und spielt. Was ich erreichen möchte, ist, wenn Sie einen Klaviertasten doppelklicken, sollte der Code überprüfen und sehen, ob es die gleiche Note ist wie die zufällig gewählte, irgendwelche Ideen?

Hier ist der Code:

package com.stefanawesome.piano; 

import android.content.pm.ActivityInfo; import 
android.media.AudioManager; import android.media.MediaPlayer; import 
android.media.SoundPool; import android.os.Build; import 
android.provider.ContactsContract; import 
android.support.v7.app.AppCompatActivity; import android.os.Bundle; 
import android.view.View; import android.widget.Button; import 
android.widget.ImageButton; import android.widget.TextView; 

import java.util.ArrayList; import java.util.List; import 
java.util.Random; 


public class MainActivity extends AppCompatActivity { 

    //Declaring variables and array: 
    ImageButton NoteNew; 
    ImageButton Repeat; 
    Button c, d, e, f, g, a, b, high; 
    List<Integer> soundList = new ArrayList<Integer>(); 
    private SoundPool soundpool; 
    private int sound_c, sound_d, sound_e, sound_f, sound_g, sound_a, sound_b, sound_high; 

    //Random Note Function: 
    int last; 

    private void playRandomSound() { 
     int randomInt = (new Random().nextInt(soundList.size())); 
     last=randomInt; 
     int rSound = soundList.get(randomInt); 
     MediaPlayer mp = MediaPlayer.create(this, rSound); 
     mp.start(); 
    } 

    //Repeat Note 
    private void playlastRandomSound() { 
     int rSound = soundList.get(last); 
     MediaPlayer mp = MediaPlayer.create(this, rSound); 
     mp.start(); 
    } 


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

     //Find View by ID all here: 
     soundList.add(R.raw.c); 
     soundList.add(R.raw.d); 
     soundList.add(R.raw.e); 
     soundList.add(R.raw.f); 
     soundList.add(R.raw.g); 
     soundList.add(R.raw.a); 
     soundList.add(R.raw.b); 
     soundList.add(R.raw.chigh); 
     NoteNew = (ImageButton) findViewById(R.id.Newnote); 
     Repeat = (ImageButton) findViewById(R.id.Repeat); 
     c = (Button) findViewById(R.id.C); 
     d = (Button) findViewById(R.id.D); 
     e = (Button) findViewById(R.id.E); 
     f = (Button) findViewById(R.id.F); 
     g = (Button) findViewById(R.id.G); 
     a = (Button) findViewById(R.id.A); 
     b = (Button) findViewById(R.id.B); 
     high = (Button) findViewById(R.id.high); 


     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
      soundpool = new SoundPool.Builder().setMaxStreams(5).build(); 
     } else { 
      soundpool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0); 

     } 

     //Soundpools over here: 
     sound_c = soundpool.load(this, R.raw.c, 1); 
     sound_d = soundpool.load(this, R.raw.d, 1); 
     sound_e = soundpool.load(this, R.raw.e, 1); 
     sound_f = soundpool.load(this, R.raw.f, 1); 
     sound_g = soundpool.load(this, R.raw.g, 1); 
     sound_a = soundpool.load(this, R.raw.a, 1); 
     sound_b = soundpool.load(this, R.raw.b, 1); 
     sound_high = soundpool.load(this, R.raw.chigh, 1); 


     //When button gets clicked do something: 
     c.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       soundpool.play(sound_c, 1, 1, 0, 0, 1); 
      } 
     }); 

     d.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       soundpool.play(sound_d, 1, 1, 0, 0, 1); 
      } 
     }); 

     e.setOnClickListener(new View.OnClickListener() {

      } 
     }); 

     a.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       soundpool.play(sound_a, 1, 1, 0, 0, 1); 
      } 
     }); 

     b.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       soundpool.play(sound_b, 1, 1, 0, 0, 1); 
      } 
     }); 

     high.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       soundpool.play(sound_high, 1, 1, 0, 0, 1); 
      } 
     }); 
     NoteNew.setOnClickListener(new View.OnClickListener() { 
      @Override

Answer 1

c.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View view) { 
     soundpool.play(sound_c, 1, 1, 0, 0, 1); 
     if(last == 0){ 
      "You played the last note." 
     } 
    } 
}); 
    d.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View view) { 
     soundpool.play(sound_d, 1, 1, 0, 0, 1); 
     if(last == 1){ 
      "You played the last note." 
     } 
    } 
}); 

Da die Zuhörer und die Liste bekam die gleiche Reihenfolge, können Sie dies tun. Eine bessere Wahl ist es, eine andere Klasse namens Sounds oder so etwas mit Sound und ID zu erstellen.
