想要在播放音頻剪輯後移動下一個活動（請參閱圖像）

Question

我正在創建一個應用程序，其中活動移動將在播放音頻剪輯後的下一個活動中進行。但是當我寫代碼時只有音頻部分正在工作，下一頁不會來。我正在給我的代碼。請參閱我的代碼圖片。

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.foood); 

    ImageButton btnbreakfast = (ImageButton) findViewById(R.id.breakfast); 

    btnbreakfast.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View V) { 
      MediaPlayer audio = MediaPlayer.create(Food.this, R.raw.vada); 
      audio.start(); 
     } 
    }); 
} 

public void audio() { 
    Intent intent = new Intent(Food.this, breakfast.class); 
    startActivity(intent); 
} 

Answer 1

Full code: 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.foood); 

    ImageButton btnbreakfast = (ImageButton) findViewById(R.id.breakfast); 

    btnbreakfast.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View V) { 
      MediaPlayer audio = MediaPlayer.create(Food.this, R.raw.vada); 
      audio.start(); 
    audio.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { 
       @Override 
       public void onCompletion(MediaPlayer mp) { 
        nextScreen(); 
       } 
      }); 
     } 
    }); 
} 

public void nextScreen() { 
    Intent intent = new Intent(Food.this, breakfast.class); 
    startActivity(intent); 
} 

Answer 2

添加此

audio.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { 
    public void onCompletion(MediaPlayer mp) { 
     audio(); // call next activity 
    } 
}); 

後audio.start();

更新

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.foood); 
    ImageButton btnbreakfast = (ImageButton) findViewById(R.id.breakfast); 

    btnbreakfast.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View V) { 
      MediaPlayer audio = MediaPlayer.create(Food.this, R.raw.vada); 
      audio.setOnCompletionListener(mediaListener); 
      audio.start(); 
     } 
    }); 
} 

public void audio() { 
    Intent intent = new Intent(Food.this, breakfast.class); 
    startActivity(intent); 
} 

MediaPlayer.OnCompletionListener mediaListener = new MediaPlayer.OnCompletionListener() { 
    public void onCompletion(MediaPlayer mp) { 
     audio(); // call next activity 
    } 
}
