将音频文件保存到新创建的文件夹-Android开发[副本]

Question

String mediaFile = null;
mediaFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myRecordings.mp3";

但我想创建一个文件夹与应用程序的名称，并能够保存录制的音频到该文件夹。有人能告诉我怎么做吗？我成功地创建了文件夹,但我不知道如何将mediaFile移动到其中：

String newFolder = "/FolderName";
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
File myNewFolder = new File(extStorageDirectory + newFolder);
myNewFolder.mkdir();
mediaFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myRecordings.mp3"

Answer 1

只需将该文件夹添加到路径中。像这样：

String sep = File.separator; // Use this instead of hardcoding the "/"
String newFolder = "FolderName";
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
File myNewFolder = new File(extStorageDirectory + sep + newFolder);
myNewFolder.mkdir();
mediaFile = Environment.getExternalStorageDirectory().toString() 
  + sep + newFolder + sep + "myRecordings.mp3";
