我正在尝试将录制的音频文件保存在我想要的文件夹中,而不是默认文件夹。但不知怎的,我没有这样做。
我的代码:
Intent recordIntent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
Uri mUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "/Record/sound_"+ String.valueOf(System.currentTimeMillis()) + ".amr"));
recordIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri);
startActivityForResult(recordIntent, RESULT_OK);
它确实调用了录音笔应用程序。并且当我按下停止按钮时,它返回到我的应用程序并出现一个吐司,说它已保存。但是,而不是保存在我的记录文件夹中,它保存在默认文件夹中。
我意识到logcat中有错误信息:
01-29 01:34:23.900: E/ActivityThread(10824): Activity com.sec.android.app.voicerecorder.VoiceRecorderMainActivity has leaked ServiceConnection com.sec.android.app.voicerecorder.util.VRUtil$ServiceBinder@405ce7c8 that was originally bound here
当我调用相机应用程序时,我不确定代码是否有效。

以这种方式,用MediaRecorder录制:
开始录制:
public void startRecording()
{
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(getFilename());
recorder.setOnErrorListener(errorListener);
recorder.setOnInfoListener(infoListener);
try
{
recorder.prepare();
recorder.start();
}
catch (IllegalStateException e)
{
e.printStackTrace();
} catch (IOException e)
{
e.printStackTrace();
}
}
停止:
private void stopRecording()
{
if(null != recorder)
{
recorder.stop();
recorder.reset();
recorder.release();
recorder = null;
}
对于选定的文件夹:
private String getFilename()
{
String filepath = Environment.getExternalStorageDirectory().getPath();
File file = new File(filepath,AUDIO_RECORDER_FOLDER);
if(!file.exists()){
file.mkdirs();
}
return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp3");
}

我已经找到了解决这个问题的方法,即使它需要一轮才能完成,而不是直截了当,但它是我得到的最好的,它也有效。
而不是使用额外包含的语音记录器应用程序,我只是在没有任何输入的情况下调用它:
Intent recordIntent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
startActivityForResult(recordIntent, 1111);
然后,添加一个onActivityResult,请求代码== 1111(取决于您放置的内容)并从记录器“Sounds”的默认文件夹中检索包含扩展名“3ga”的最后修改文件
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 1111)
{
File folder = new File(Environment.getExternalStorageDirectory(), "/Sounds");
long folderModi = folder.lastModified();
FilenameFilter filter = new FilenameFilter()
{
public boolean accept(File dir, String name)
{
return (name.endsWith(3ga));
}
};
File[] folderList = folder.listFiles(filter);
String recentName = "";
for(int i=0; i<folderList.length;i++)
{
long fileModi = folderList[i].lastModified();
if(folderModi == fileModi)
{
recentName = folderList[i].getName();
}
}
}
这样,我可以得到文件的名称,并用它进行修改(例如重命名)。
希望这有助于其他人。 =)

之前我用过这种方式,对我来说没问题!
private MediaRecorder mRecorder = null;
public void startRecording() {
if (mRecorder == null) {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mRecorder.setOutputFile(getFilename());
try {
mRecorder.prepare();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mRecorder.start();
}
}
停止录制:
public void stopRecording() {
if (mRecorder != null) {
mRecorder.stop();
timer.cancel();
mRecorder.release();
mRecorder = null;
}
}
保存文件:
@SuppressLint("SdCardPath")
private String getFilename() {
file = new File("/sdcard", "MyFile");
if (!file.exists()) {
file.mkdirs();
}
return (file.getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp3");
}
if you want to delete folder after recording use this in function of stopping:
boolean deleted = file.delete();
I hope it can be helpful.
