我正在开发一个流音频歌曲的应用程序，所以我试图显示该音频歌曲的总持续时间，这是我到目前为止所做的但无济于事。我跟着这个link，但仍然无法。

private TextView tv_mediaFileLengthInMilliseconds  = null;
MediaPlayer player;

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {

...........
...........
tv_mediaFileLengthInMilliseconds = (TextView)findViewById(R.id.duration);   
tv_mediaFileLengthInMilliseconds.setText(player.getDuration());

}

布局：

<TextView
            android:id="@+id/duration"
            android:layout_width="136dp"
            android:layout_height="wrap_content"
            android:ellipsize="middle"
            android:gravity="center_horizontal"
            android:singleLine="true"          
            android:textColor="@android:color/black" />

Android：流媒体之前的音频歌曲的持续时间？
