在一個開源項目看到是用的webview 實現的
1. 這是在asset中的一個模板html
?
<html> <head> <title>News Detail</title> <meta name="viewport" content="width=device-width, minimum-scale=0.5, initial-scale=1.2, maximum-scale=2.0, user-scalable=1" /> <link rel="stylesheet" type="text/css" href="css.css" /> </head> <body> <div id="header"> <h3> #title# </h3> <div class="date">#time#</div> </div> <div id="content"> #content# </div> </body> </html>
?
2.模板的css
?
body { font-family: Helvetica, "Microsoft Yahei", Verdana, Helvetica, SimSun, Arial, "Arial Unicode MS", MingLiu, PMingLiu, "MS Gothic", sans-serief; margin: 0; padding: 0 8px; background-color: #efeff0; color: #333; word-wrap: break-word; } p { margin-top: 0; margin-bottom: 5pt; line-height: 1.6em; } #header { text-align: center; background: transparent url('webBgLine.png') repeat-x scroll center bottom; padding-top: 6pt; margin-bottom: 5pt; -webkit-background-size: 320px 2px; } #header h3 { margin-bottom: 0px; margin-top: 5px; font-size: 16pt; padding: 0 5pt; color: #464646; line-height: 1.3em; } .date { color: #8e8e8e; font-size: 12pt; padding: 8pt 0; } #content { font-size: 14pt; line-height: 1.8; } img { max-width: 310px; height: auto; } div.bimg { text-align: center; padding: 0; } .photo_title { font-weight: bold; font-size: 16pt; margin-top: 15px; } .langs_cn { color: #006200; } audio { width: 100% } * { -webkit-touch-callout: none; /* prevent callout to copy image, etc when tap to hold */ /*-webkit-text-size-adjust: none;*/ /* prevent webkit from resizing text to fit */ -webkit-tap-highlight-color: rgba(0, 0, 0, 0.15); /* make transparent link selection, adjust last value opacity 0 to 1.0 */ /*-webkit-user-select: none; /* prevent copy paste, to allow, change 'none' to 'text' */ } @media screen and (-webkit-device-pixel-ratio: 2) { #header { background-image: transparent url('webBgLine@2x.png') repeat-x scroll center bottom; -webkit-background-size: 320px 1px; } }

3.測試的一個html文件 將來會在網絡中獲取
主要的代碼：
?
