Android如何获取asset目录下所有文件的路径

package com.hangcheng.util;

import java.io.File;

import java.io.InputStream;

private String[] files;

public GetfilesFromAssets(Context context) {
this.activity = (Activity) context;

}

// public void deepFile(Context ctxDealFile, String path) {
// try {
// String str[] = ctxDealFile.getAssets().list(path);
// if (str.length > 0) {// 如果是目录
// File file = new File("/data/" + path);

// path = path + "/" + string;
// System.out.println("zhoulc:\t" + path);
// // textView.setText(textView.getText()+"\t"+path+"\t");

}

public List listHtmlOfAssets() {
List list = new ArrayList();

for (int i = 0; i < files.length; i++) {
HashMap map = new HashMap();
map.put("htmlname", files[i]);
list.add(map);
}
return list;
}
}
