我不知道如何更改Webview的字体。

现在下载应用的html和css样式以其他方式更改字体？

另外，我希望网站实时更改字体。

我该怎么做。

Answer 1

如果不更改网页内容，则无法更改字体。

WebView基本上是一个显示网页的视图 网页可能是静态的（例如html）或动态的。但它并没有改变网页的外观和感觉。所以它将显示与网页完全相同的文本。如果您需要更改字体，则必须在网页中更改它（可能是html）。

// Put your font file in assets

private WebView wv;

wv = (WebView)findViewById(R.id.wv);
wv.setBackgroundColor(Color.BLACK);

String my_text=getData("I am android developer");

wv.loadDataWithBaseURL("file:///android_asset//Gill Sans MT.ttf", t, "text/html", "UTF-8", "null" );

private String getData(String s){

    String htmlData="<font color='white'>" + s + "</font>";
     String PAGE_HTML =
            "<html>\n" +
            "  <style type=\"text/css\"> \n" + 
            "   @font-face { \n" + 
            "       font-family: MyFont; \n" + 
            "       src: url(\"file:///android_asset/Gill Sans MT.ttf\") \n" + 
            "   } \n" + 
            "   body { \n" + 
            "       font-family: MyFont; \n" + 
            "       font-size: medium; \n" + 
            "       text-align: justify; \n" + 
            "   } \n" + 
            "  </style> \n" + 
            "  <body>\n" +
