Ich habe ein Programm in Android Studio erstellt, das 10 Bildtasten hat. Jede angeklickte Bildtaste erzeugt einen Ton. Wenn ich sie jedoch auf dem Emulator starte, wird nur der erste 7 Bildknopf einen Ton erzeugen (egal in welcher Reihenfolge der Knopf, auf den ich geklickt habe). Ich bin neu in diesem, hilf mir, das ist mein Code:

public class playtimang extends AppCompatActivity {

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

    final MediaPlayer satukecik = MediaPlayer.create(this, R.raw.one_kecik);
    final MediaPlayer satubesar = MediaPlayer.create(this, R.raw.one_besar);
    final MediaPlayer duakecik = MediaPlayer.create(this, R.raw.two_kecik);
    final MediaPlayer duabesar = MediaPlayer.create(this, R.raw.two_besar);
    final MediaPlayer tigakecik = MediaPlayer.create(this, R.raw.three_kecik);
    final MediaPlayer tigabesar = MediaPlayer.create(this, R.raw.three_besar);
    final MediaPlayer limakecik = MediaPlayer.create(this, R.raw.five_kecik);
    final MediaPlayer limabesar = MediaPlayer.create(this, R.raw.five_besar);
    final MediaPlayer enamkecik = MediaPlayer.create(this, R.raw.six_kecik);
    final MediaPlayer enambesar = MediaPlayer.create(this, R.raw.six_besar);

    ImageButton satu_kecikIB = (ImageButton) this.findViewById(R.id.satukecikIB);
    ImageButton satu_besarIB = (ImageButton) this.findViewById(R.id.satubesarIB);
    ImageButton dua_kecikIB = (ImageButton) this.findViewById(R.id.duakecikIB);
    ImageButton dua_besarIB = (ImageButton) this.findViewById(R.id.duabesarIB);
    ImageButton tiga_kecikIB = (ImageButton) this.findViewById(R.id.tigakecikIB);
    ImageButton tiga_besarIB = (ImageButton) this.findViewById(R.id.tigabesarIB);
    ImageButton lima_kecikIB = (ImageButton) this.findViewById(R.id.limakecikIB);
    ImageButton lima_besarIB = (ImageButton) this.findViewById(R.id.limabesarIB);
    ImageButton enam_kecikIB = (ImageButton) this.findViewById(R.id.enamkecikIB);
    ImageButton enam_besarIB = (ImageButton) this.findViewById(R.id.enambesarIB);

    satu_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            satukecik.start();
        }
    });

    satu_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            satubesar.start();
        }
    });

    dua_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            duakecik.start();
        }
    });

    dua_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            duabesar.start();
        }
    });

    tiga_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            tigakecik.start();
        }
    });

    tiga_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            tigabesar.start();
        }
    });

    lima_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            limakecik.start();
        }
    });

    lima_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            limabesar.start();
        }
    });

    enam_kecikIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            enamkecik.start();
        }
    });

    enam_besarIB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            enambesar.start();
        }
    });
