如果你想使用舞台网页视图来渲染epub,只需直接传递epub ...... android原生网页工具包浏览器几乎支持所有渲染格式。
var stageWebView:StageWebView = new StageWebView;
stageWebView.stage = stage;
stageWebView.viewPort = new Rectangle(0, 0, stage.stageWidth, stage.stageHeight-100);
stageWebView.loadURL("http://localhost/eboard.pdf"); // use any path
您不需要任何zip / unzip或解析....但如果您不去网页查看,那么您可能需要...
