Problems loading html asset into webview

问题:

I am having difficulty in loading a html file from my project assets folder into a webview. I have looked at dozens of tutorials and solutions but none seem to work for me.

In my project's assets folder I have two simple html files. index.html and faq.html (The plan is to utilise this structure for my help documentation)

My code:

    WebView wv = (WebView)findViewById(R.id.webview1);
    wv.setWebViewClient(new WebViewClient() {  
          @Override  
          public boolean shouldOverrideUrlLoading(WebView view, String url)  
          {  
            view.loadUrl(url);
            return true;
          }  
        });         
    wv.loadUrl("file:///android_asset/index.html");    

The webview displays the following:

Web Page Not Available

The Web Page at file:///android_asset/index.html could not be loaded as:

The requested file was not found. index.html

From everything I have read what I have here should work, but it does not.

回答1:

your usage is right, so if has this problem, you need check the index.html file existed or not carefully, also you can clean the project, and rebuild it.

You can try this code ....

WebView myBrowser;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        String myURL = "file:///android_asset/index.html";
        myBrowser=(WebView)findViewById(R.id.mybrowser);

        /*By default Javascript is turned off,
         * it can be enabled by this line.
         */
        myBrowser.getSettings().setJavaScriptEnabled(true);
        myBrowser.setWebViewClient(new WebViewClient());

        myBrowser.loadUrl(myURL);

    }
