推荐答案

您需要运行Java脚本

you need to run java script

 public static String Highlightscript = " <script language=\"javascript\">" +

    "function highlightSelection(){" +
    "var userSelection = window.getSelection();" + 
    "for(var i = 0; i < userSelection.rangeCount; i++)"
    + "  highlightRange(userSelection.getRangeAt(i));" +
     "}" +
    "function highlightRange(range){"+
    "span = document.createElement(\"span\");"+
    "span.appendChild(range.extractContents());"+
    "span.setAttribute(\"style\",\"display:block;background:#ffc570;\");"+
    "range.insertNode(span);}"+
    "</script> ";

和

  webView.loadUrl("javascript:highlightSelection()");

确保您启用了javascript

make sure you enabled javascript

WebView myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
