在Webview中打开本地Html文件 - Android

我在根文件夹中保存了一个文件,并尝试在webview中打开它.

这是我保存的代码:

    OutputStream outstream = null;
    outstream = openFileOutput(fileName ,MODE_WORLD_READABLE);

    /// if file the available for writing
    if (outstream != null) {
        /// prepare the file for writing
        OutputStreamWriter outputreader = new OutputStreamWriter(outstream);
        BufferedWriter buffwriter = new BufferedWriter(outputreader);

        /// write the result into the file
        buffwriter.write(result);
    }

    /// close the file
    outstream.close();

} catch (java.io.FileNotFoundException e) {
    System.out.println("File not found in the writing...");
} catch (IOException e) {
    System.out.println("In the writing...");
}

这是我调用文件的代码:

                    fileView.getSettings().setJavaScriptEnabled(true);
            fileView.loadUrl("file:///" + name); <---

并在应用程序内部,它给我一个文件未找到错误.

任何见解都有帮助.

WebView mWebView=(WebView)findViewById(R.id.mWebView);

            mWebView.loadUrl("file:///book.html");
            mWebView.getSettings().setJavaScriptEnabled(true);
            mWebView.getSettings().setSaveFormData(true);
            mWebView.getSettings().setBuiltInZoomControls(true);
            mWebView.setWebViewClient(new MyWebViewClient());

private class MyWebViewClient extends WebViewClient 
{ 
    @Override 
    //show the web page in webview but not in web browser
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
        view.loadUrl (url); 
        return true;
    }
}

试试这个

实际上,当您使用file:///...
Then 打开URL时,意味着您应该将文件保存在assets目录下(比如test.html).现在假设你必须访问test.html文件,你需要这样写

loadURL("file:///android_asset/test.html');

假设异常没有被击中,路径是错误的.

file:///告诉浏览器查找/ name

openFileOutput(fileName)告诉应用程序在/fileName中写入

您的网址应为"file:///"+ getFilesDir()+ File.separator + fileName
