在Android音樂播放器中播放音頻文件

Question

我的Android項目的原始文件夾中有一些音頻文件。我希望通過Android的默認音樂播放器播放這些音頻文件。有人可以分享一些示例代碼片段來解釋過程。

Answer 1

Intent intent = new Intent(android.content.Intent.ACTION_VIEW); 

Uri data = Uri.parse("file://"+Environment.getExternalStorageDirectory() 
     .getAbsolutePath()+"/" + fileName); 
String type = "audio/mp3"; 
intent.setDataAndType(data, type); 
startActivity(intent); 

fileName是音頻的名字寫在你SDCard。

首先聲明MediaPlayer對象：

MediaPlayer mSoundPlayer; 

添加此功能：

//Play music 
    public void playSound(int id){ 
      try{ 
       mSoundPlayer = MediaPlayer.create(mContext, id); 
       mSoundPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
        @Override 
        public void onPrepared(MediaPlayer arg0) { 
         mSoundPlayer.start(); 

        } 

       }); 
       mSoundPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { 

        @Override 
        public void onCompletion(MediaPlayer mp) { 
         // TODO Auto-generated method stub 
         mSoundPlayer.release(); 
        }}); 
      } 
      catch (Exception e) { 
       // TODO: handle exception 
       Log.v("Sound Exception","Sound Exception = "+e.getMessage()); 
      } 
    } 

電話本：

playSound(R.raw.sound1); 

這將是一個很好的做法，釋放MediaPlayer：

@Override 
    public void onPause(){ 
     super.onPause(); 
     if(mSoundPlayer!=null) 
      mSoundPlayer.release(); 
    } 

謝謝。

下面是示例代碼片段...

For playing audio files in android

Playing audio

public void splashPlayer() { 
VideoView videoHolder = new VideoView(this); 
setContentView(videoHolder); 
Uri video = Uri.parse("android.resource://" + getPackageName() + "/" 
    + R.raw.splash); 
videoHolder.setVideoURI(video); 
videoHolder.setOnCompletionListener(new OnCompletionListener() { 
    public void onCompletion(MediaPlayer mp) { 
    jumpMain(); //jump to the next Activity 
    } 
}); 
videoHolder.start(); 
}

Answer 4

我試過這段代碼： -

button.setOnClickListener(new OnClickListener() 
{ 

@Override 
public void onClick(View v) 
{ 
Uri uri = Uri.parse("R.raw.fashion.mp3");//the audio file 
Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
startActivity(intent); 

} 
}); 

但是，當我運行此代碼;該應用程序崩潰，LogCat顯示：「ActivityNotFoundException」...找不到處理意圖的活動。

Answer 5

試試這個可能會有幫助。

Uri data = Uri.parse("file://"+Environment.getExternalStorageDirectory() 
       .getAbsolutePath()+"/" + audioName); 
     Intent intent = new Intent(android.content.Intent.ACTION_VIEW, data); 

     String type = "audio/mp3"; 
     intent.setDataAndType(data, type); 
     startActivity(intent);
