本文介绍了如何通过Android中的AssetManager来创建文件夹并操作文件，包括列出路径下的所有文件、打开特定文件等步骤。同时也讨论了在使用过程中遇到的问题。

Step 1:

Create a folder under assets, such as "files", and put some files in it.

Step 2:

Use AssetManager to list all the file in the path.

files = assetManager.list(assetPath);

Step 3:

Open the specific file, and do something.

public void useAsset(){ AssetManager assetManager = getAssets(); String assetPath = "files"; String [] files = null; try { files = assetManager.list(assetPath); } catch (IOException e) { e.printStackTrace(); } if(files == null){ return; } for(int i = 0; i < files.length; i++){ String filePath = assetPath + "/" + files[i]; try { InputStream inputStream = assetManager.open(filePath); FileOutputStream fileOutputStream = new FileOutputStream(PATH + "/" + files[i]); byte [] b = new byte [1]; while(inputStream.read(b) != -1){ fileOutputStream.write(b); } fileOutputStream.flush(); inputStream.close(); fileOutputStream.close(); } catch (IOException e) { } } }

Some problems:

1. Why is the path "/asset" useless? It can be list by AssetManager.list("/").
