在Android中播放媒体

Question

my app is playing some audio files, but if the user hits the play button twice, it will play then it will play again (something like that).

I would like the next action to happen JUST when the first execution of the audio file is over.

How can I do that?

Here is my code:

MediaPlayer mMediaPlayer = new MediaPlayer();
try {
    mMediaPlayer.setDataSource((endMidia));
    mMediaPlayer.prepare();
} catch (IllegalArgumentException e) {
    e.printStackTrace();
}                                        
mMediaPlayer.start();

Any help is appreciatted!

Answer 1

您可以使用MediaPlayer.isPlaying（）进行检查。

Answer 2

There are listeners on MediaPlayer events like OnCompletionListener

http://developer.android.com/reference/android/media/MediaPlayer.html#setOnCompletionListener(android.media.MediaPlayer.OnCompletionListener )

and others

Answer 3

check if condition as shown in below code

  MediaPlayer mMediaPlayer = new MediaPlayer();
  try {
    mMediaPlayer.setDataSource((endMidia));
    mMediaPlayer.prepare();
      } catch (IllegalArgumentException e) {
      e.printStackTrace();
    }    
   if(!mMediaPlayer.isPlaying()){                                    
        mMediaPlayer.start();
    }
