如何以编程方式将录制的音频文件保存在另一个文件夹中?

问题描述

我正在尝试将录制的音频文件保存在我想要的文件夹中，而不是默认文件夹中.但不知何故我没有这样做.

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);

它确实调用了录音机应用程序.而且当我按下停止按钮时，它会返回到我的应用程序并出现一个吐司，说它已保存.但是，不是保存在我的 Record 文件夹中，而是保存在默认文件夹中.

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 logcat 中有错误消息:

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

我不知道哪里出了问题，因为当我调用相机应用程序时代码有效.

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

推荐答案

我已经找到了解决这个问题的方法，尽管它需要一个回合来完成而不是直截了当，但这是最好的我有，它也能用.

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.

我没有调用包含额外内容的录音机应用程序，而是在没有任何输入的情况下调用它:

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，请求代码 == 1111(取决于您放置的内容)并从记录器声音"的默认文件夹中检索包含扩展名3ga"的最后修改的文件

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();
        }
    }
}

通过这种方式，我可以获得文件的名称并对其进行修改(例如重命名).

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