如何保存在另一个文件夹中录制的音频文件编程？

问题描述

我试图挽救，我希望它是而不是默认的文件夹中的文件夹中录制的音频文件。但不知怎的，我没有这样做。

i'm trying to save the recorded audio files in a folder that i wanted it to be rather then the default folder. but somehow i failed to do so.

我的code：

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);

它确实调用录音笔的应用程序。而且当我preSS停止按钮，就回到我的应用程序，并拥有举杯出现称其保存。但是，而不是节约在我的录音文件夹，将其保存在默认的文件夹。

it did calls the voice recorder app. and also when i press the stop button, it return to my app and have a toast appeared saying its saved. but, rather then saving in my Record folder, it save in the default folder.

我意识到，在logcat中的错误信息：

i realized that there is error msg in the logcat :

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

我不知道问题出在哪里为code工作时，我调用摄像头应用程序。

i'm not sure what went wrong as the code works when i call the camera app.

推荐答案

我已经找到一种方法来解决这个问题，尽管它需要一个圆形去做而不是让的地步直，但其最好的，我已经得到了它也工作。

i've found a way to solve this problem, even though it takes a round to do it rather then getting to the point straight, but its the best that i've got and it also work.

而不是调用额外的语音记录器的应用程序包括，我只是把它在没有任何输入：

instead of calling the voice recorder app with extra included, i just call it without any input :

Intent recordIntent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
startActivityForResult(recordIntent, 1111);

然后，添加一个onActivityResult，与请求code = = 1111（取决于你放）和检索的最后一个修改后的文件，它由从记录仪声音的默认文件夹的扩展名3GA的

then, add an onActivityResult, with the request code == 1111 (depends on what you put) and retrieve the last modified file that consist of the extension "3ga" from the default folder of recorder "Sounds"

@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();
        }
    }
}

这样一来，我可以得到该文件的名称也做了修改（例如，重命名）吧。

this way, i can get the name of the file and also do the modification (e.g renaming) with it.

希望这可以帮助其他人。 =）
