我用下面的code录制音频:
I am using the following code to record audio:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("audio/*");
startActivityForResult(Intent.createChooser(intent, "Select audio source"), CardList.ACTIVITY_RECDAUDIO);
当结果回来我做到以下几点:
When the result comes back I do the following:
Uri u = intent.getData();
String audioUri = u.getPath();
InputStream in = new BufferedInputStream(this.getContentResolver().openInputStream(u));
我想知道的记录以秒为单位的时间。是否有可能以某种方式查询呢?如果一切都失败,我可以编程播放的剪辑和时间,但我想preFER更直接的方法,如果可能的话。谢谢!
I would like to know how long the recording is in seconds. Is it possible to query this somehow? If all else fails I can play the clip programatically and time it, but I would prefer a more direct method if possible. Thanks!
我不知道这是不是对你不够快。但如果你不知道 - 你没有真正发挥它。这足以创建的MediaPlayer
实例,并设置文件的路径和呼叫 getDuration()
。
I don't know if this is fast enough for you. But in case you don't know - you don't have to actually play it. It is enough to create MediaPlayer
instance and set the path of the file and the call getDuration()
.
MediaPlayer mp = MediaPlayer.create(yourActivity, Uri.parse(path));
int duration = mp.getDuration();
