you can use Context.getFilesDir()method to get the path to the internal storage
您可以使用Context.getFilesDir()方法来获取内部存储的路径

when using this line FileOutputStream fileOuputStream = openFileOutput(name, MODE_PRIVATE);the internal storage path is obtained by the default implementation of the openFileOutput()method. A new file is created at that location with the specified name. Now when you want to get the path of the same file, you can use the getFilesDir()to get the absolute path to the directory where the file was created. You can do something like this :-
使用此行时FileOutputStream fileOuputStream = openFileOutput(name, MODE_PRIVATE);，内部存储路径是通过该openFileOutput()方法的默认实现获得的。在该位置创建一个具有指定名称的新文件。现在，当您想要获取同一文件的路径时，可以使用getFilesDir()来获取创建文件的目录的绝对路径。你可以做这样的事情：-
File file = new File(getFilesDir() + "/" + name);
File file = new File(getFilesDir() + "/" + name);
