android - Android:除非先按一个按钮，否则按钮2不会播放声音

Question

我试图不先按下按钮1就能使按钮2播放声音。这是我的代码。因此，如果我按下按钮2，直到我按下按钮1为止，声音不会播放

@Override
protected void onCreate(Bundle LiamIsTheBest) {
    // TODO Auto-generated method stub
    super.onCreate(LiamIsTheBest);
    setContentView(R.layout.liam);


    Button boton = (Button) findViewById(R.id.button1);
     boton.setOnClickListener(new View.OnClickListener() {
       @Override
        public void onClick(View v) { // onClick Method
        // Your Onclick Action Here
            MediaPlayer mp = MediaPlayer.create( MainActivity.this, R.raw.eat);  
              mp.start();

              Button play = (Button) findViewById(R.id.button2);
              play.setOnClickListener(new View.OnClickListener() {
               @Override
               public void onClick(View v) {
                MediaPlayer mp = MediaPlayer.create(MainActivity.this, R.raw.play);  
                mp.start();
               }
              });


        }


});

}
      };

Xml

<Button
    android:id="@+id/button1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="I want to eat" />

<Button
    android:id="@+id/button2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="I want to play" />

用这个

@Override
protected void onCreate(Bundle LiamIsTheBest) {
    super.onCreate(LiamIsTheBest);
    setContentView(R.layout.liam);


    Button boton = (Button) findViewById(R.id.button1);
    boton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            MediaPlayer mp = MediaPlayer.create( MainActivity.this, R.raw.eat);  
            mp.start();
        }
    });

    Button play = (Button) findViewById(R.id.button2);
    play.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            MediaPlayer mp = MediaPlayer.create(MainActivity.this, R.raw.play);  
            mp.start();
        }
    });
}
