如何使用語音控制音樂播放器

Question

我正在開發一個應用程序，它可以使用語音控制音樂播放器。例如，當我說「播放」音樂播放器播放歌曲，或者說「下一個」音樂播放器將播放下一首歌曲等。我已經Google，但沒有找到任何想法或源代碼。

問題：

1. 理念使用語音

2. 源代碼示例來控制音樂播放器。

提前致謝。

您將需要此：

private void playNextMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_NEXT)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_NEXT)); 
    sendOrderedBroadcast(i, null); 

    playPlayMusic(); 
} 

private void playPreviousMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PREVIOUS)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PREVIOUS)); 
    sendOrderedBroadcast(i, null); 

    playPlayMusic(); 
} 

private void playPauseMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PAUSE)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PAUSE)); 
    sendOrderedBroadcast(i, null); 
} 

private void playPlayMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PLAY)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PLAY)); 
    sendOrderedBroadcast(i, null); 
} 

private void playStopMusic() { 
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_STOP)); 
    sendOrderedBroadcast(i, null); 

    i = new Intent(Intent.ACTION_MEDIA_BUTTON); 
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_STOP)); 
    sendOrderedBroadcast(i, null); 
}
