步骤1：准备字体，后缀为ttf,otf格式。可以去绿斗堂字体网下载http://www.lvdoutang.com
步骤2：把字体拷贝到项目工程mian\assets\fonts目录下。
步骤3：在assets目录下创建.css文件。
参考格式：
/** 微软雅黑 */
@font-face {
font-family: 'Microsoft YaHei';
src: url('file:///android_asset/fonts/Microsoft_YaHei.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
/** 黑体 */
@font-face {
font-family: 'SimHei';
src: url('file:///android_asset/fonts/SimHei.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
/** 宋体 */
@font-face {
font-family: 'SimSun';
src: url('file:///android_asset/fonts/SimSun.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
/** 宋体(默认) */
@font-face {
font-family: 'FangSong_GB2312';
src: url('file:///android_asset/fonts/FangSong_GB2312.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
步骤4：拼接后台返回的富文本格式的Json
参考方法：
public static String getNewContent(String htmltext, String title) {
Document doc = Jsoup.parse(htmltext);
Elements elements1 = doc.getElementsByTag("img");
Elements elements2 = doc.getElementsByTag("a");
for (Element element : elements1) {
element.attr("width", "100%").attr("height", "auto");
}
for (Element element : elements2) {
element.attr("style", "word-wrap:break-word");
}
String assetsFontCSS = "<link href=\"file:///android_asset/myfont.css\" rel=\"stylesheet\" type=\"text/css\"/>\n";
String htmlSource = doc.toString();
String htmlAdded = htmlSource.replace("</head>",
"\n" + assetsFontCSS +
"<meta charset=\"UTF-8\"/>\n" +
"<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n" +
"<title>" + title + "</title>\n" +
"</head>").replace("<body>", "<body style=\"margin:0;padding:0;\">");
return "<!DOCTYPE html>\n" + htmlAdded;
}
