Android从Assets拷贝文件以及文件夹到指定目录

public static void copyFilesFromAssets(Context context, String assetsPath, String savePath){
try {
String fileNames[] = context.getAssets().list(assetsPath);// 获取assets目录下的所有文件及目录名
if (fileNames.length > 0) {// 如果是目录
File file = new File(savePath);
file.mkdirs();// 如果文件夹不存在，则递归
for (String fileName : fileNames) {
copyFilesFromAssets(context, assetsPath + "/" + fileName,
savePath + "/" + fileName);
}
} else {// 如果是文件
InputStream is = context.getAssets().open(assetsPath);
FileOutputStream fos = new FileOutputStream(new File(savePath));
byte[] buffer = new byte[1024];
int byteCount = 0;
while ((byteCount = is.read(buffer)) != -1) {// 循环从输入流读取
// buffer字节
fos.write(buffer, 0, byteCount);// 将读取的输入流写入到输出流
}
fos.flush();// 刷新缓冲区
is.close();
fos.close();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
