我有一个简单的活动,创建一个WebView来加载Facebook评论,例如
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); WebView myWebView = (WebView) findViewById(R.id.webView); WebSettings webSettings = myWebView.getSettings(); webSettings.setJavaScriptEnabled(true); // myWebView.loadUrl("http://192.168.0.2/facebook.html"); // See 1st image myWebView.loadUrl("file:///android_asset/facebook.html"); // See 2nd image }
只有远程html文件的调用工作,但本地的工作不起作用.请参阅以下图像:
通过远程文件
通过本地文件
和facebook.html的内容
![<!DOCTYPE html> <html> <head> <Meta name="viewport" content="width=device-width,initial-scale=1.0"> </head> <body> <div id="fb-root"></div> <script>(function(d,s,id) { var js,fjs = d.getElementsByTagName(s)\[0\]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "http://connect.facebook.net/en_US/all.js#xfbml=1&appId=xxx"; fjs.parentNode.insertBefore(js,fjs); }(document,'script','facebook-jssdk'));</script> <div class="fb-comments" data-href="http://example.com" data-width="470" data-num-posts="10"></div> </body> </html>
解决方法
您需要指定基本URL.
myWebView.loadDataWithBaseURL("http://www.example.com","YOUR_HTML","text/html",null,null)
要完全替换上面的行:
BufferedReader reader = new BufferedReader(new FileReader("file:///android_asset/facebook.html")); String line; String html = ""; while((line = reader.readLine()) != null) { html += line; } reader.close(); myWebView.loadDataWithBaseURL("http://www.example.com",html,null)
