推荐答案

我有同样的问题，我所做的就是
复制的资产与一个数据库中的内容，然后从SD卡

i had the same problem what i did was copied the content of the assets to a database and then pulled it from the sdcard

这里是code复制你的资产到SD卡
所使用的逻辑如下的HTML页面放置在压缩文件中的资产文件夹
内容资产的文件夹压缩

here is the code to copy your assets to sdcard the logic used is as follows the html pages are put in the zip file in assets folder content is the name of the zip in assets folder

    boolean succussFlag = false; 
    destination="";
    destination=Environment.getExternalStorageDirectory()+"/";
    File file = new File(destination);

    if (!file.exists()){
        file.mkdirs();
    }
    else
    {
        //file.delete();
        //file.mkdir();
    }
    try
    {
        InputStream fileInput = context.getAssets().open("content.zip");
        ZipInputStream inputStream = new ZipInputStream(fileInput);

        for (ZipEntry entry = inputStream.getNextEntry(); entry != null; entry = inputStream.getNextEntry())
        {
            String innerFileName = destination +  entry.getName();
            System.out.println("destination::::"+innerFileName);
            //              Log.v("inner file name 0",""+innerFileName);
            File innerFile = new File(innerFileName);
            if (innerFile.exists())
            {

                innerFile.delete();
            }

            // Check if it is a folder
            if (entry.isDirectory())
            {
                // Its a folder, create that folder
                innerFile.mkdirs();
            }
            else
            {
                //                  System.out.println(" ::::::::::::::INNER FILE COPYING :::: " + innerFile.toString());
                FileOutputStream outputStream = new FileOutputStream(innerFileName);
                final int BUFFER = 4096;

                BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(outputStream,
                        BUFFER);

                int count = 0;
                byte[] data = new byte[BUFFER];
                while ((count = inputStream.read(data, 0, BUFFER)) != -1)
                {
                    bufferedOutputStream.write(data, 0, count);
                }
                bufferedOutputStream.flush();
                bufferedOutputStream.close();
            }

            inputStream.closeEntry();
        }
        inputStream.close();
        //          System.out.println(" ::::::::::COPIED TO PRIVATE FOLDER ::::  " );
        succussFlag=true;
    }
    catch (IOException e)
    {
        //          System.out.println("** EXCEPTION OCCURED WHILE COPYING***");
        e.printStackTrace();
        succussFlag=false;
    }

    return succussFlag;

在这之后你给下面的命令

after this you give following command

startActivity (new Intent(Intent.ACTION_VIEW,"file://"+     Environment.getExternalStorageDirectory()+"/content"+name_Html ;
         );
