推荐答案

你不要我想使用

webview.loadUrl('file:///android_asset/htmlFile.html');

对吗？

试试我在博客中找到它：

try this i found it in a blog:

    static String getHTMLDataBuffer(String url,Context context) {
    InputStream htmlStream;
    try {
    if (Utils.isReferExternalMemory() && url.contains("sdcard")) {
    String tempPath = url.substring(7, url.length());//remove file:// from the url
    File file = new File(tempPath);
    htmlStream = new FileInputStream(file);
    }else{
    String tempPath = url.replace("file:///android_asset/", "");
    htmlStream = context.getAssets().open(tempPath);
    }
    Reader is = null;
    try {
    is = new BufferedReader(new InputStreamReader(htmlStream, "UTF8"));
    } catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    }


    // read string from reader
    final char[] buffer = new char[1024];
    StringBuilder out = new StringBuilder();
    int read;
    do {
     read = is.read(buffer, 0, buffer.length);
     if (read>0) {
       out.append(buffer, 0, read);
     }
    } while (read>=0);

    return out.toString();  
    } catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    }
    return null;
    }

用法：

      String data = getHTMLDataBuffer("file:///android_asset/yourHtmlFile",this);
      webview.loadDataWithBaseURL("http://example.com", data, "text/html", "utf-8", null);
