问题描述
我是 Android 编程的新手,我希望我们使用 jqMath 在 WebView 中显示一些数学公式.
I'am newbie in Android programming and I want to us jqMath to display some math formulas in WebView.
这是我的代码:
WebView webView = (WebView)findViewById(R.id.webView1);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
String js = "<html><head>"
+ "<link rel='stylesheet' href='jqmath-0.4.0.css'>"
+ "<script src='jquery-1.4.3.min.js'></script>"
+ "<script src='jqmath-etc-0.4.0.min.js'></script>"
+ "</head><body>"
+ "<script>var s = '$ax^2+bx+c=0$ with $a≠0$';M.parseMath(s);document.write(s);</script></body>";
webView.loadData(js, "text/html", "UTF-8");
这段代码有什么问题?,
What is the problem of this code?,
更新好吧,我的问题已经解决了,但我也将 loadData 函数更改为 loadDataWithBaseURL如果有其他人遇到同样的问题,我提一下仅供参考
UPDATE well my problem have solved, but I also changed loadData function to loadDataWithBaseURL I mention just for reference if anyone else have same problem
推荐答案
您需要为 css,js 文件正确指定路径,如下所示:
You need to specify the path correctly for the css,js files as following:
WebView webView = (WebView)findViewById(R.id.webView1);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
String path="file:///android_asset/";
String js = "<html><head>"
+ "<link rel='stylesheet' href='"+path+"jqmath-0.4.0.css'>"
+ "<script src='"+path+"jquery-1.4.3.min.js'></script>"
+ "<script src='"+path+"jqmath-etc-0.4.0.min.js'></script>"
+ "</head><body>"
+ "<script>var s = '$ax^2+bx+c=0$ with $a≠0$';M.parseMath(s);document.write(s);</script></body>";
webView.loadData(js, "text/html", "UTF-8");
注意文件应该在assets文件夹中.
note that the files should be in assets folder.
