简单的WebView自适应并嵌套在ScrollView里_html/css_WEB-ITnose
因为某种原因，我们总是需要展示一些复杂的文本，Html.fromHtml()已经不能满足我们的需求，比如后台可编辑的文本在前端显示起来比较吃力，所以为了解决一些复杂的文本显示就需要用到WebView。
WebView in ScrollView
我们都知道ScrollView和WebView都有滚动的效果，所以我们需要先屏蔽WebView的滚动事件。
Stack overflow讨论
<ScrollView android:layout_width="match_parent" android:layout_height="wrap_content" android:descendantFocusability="blocksDescendants" >
中文乱码
如果出现中文乱码，你可以这样设置
webView.loadData(body, "text/html; charset=utf-8", "utf-8");
Auto Scale
这时候如果后端如果传过来的不是完整的Html，而是只有body部分的内容，那么我们就需要补充并添加一些css样式来达到自适应的效果。
Stack overflow讨论
WebView webView = new WebView(this);webView.setWebViewClient(new SimpleWebViewClient(title)); webView.getSettings().setDefaultTextEncodingName("utf-8");if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { webView.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.TEXT_AUTOSIZING);} else { webView.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NORMAL);}webView.loadData(getHtmlData(body), "text/html; charset=utf-8", "utf-8");别忘了头部的设定：
官方对自适应的最佳实践
private String getHtmlData(String bodyHTML) { String head = "<head>" + "<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0, user-scalable=no\"> " + "<style>img{max-width: 100%; width:auto; height:auto;}</style>" + "</head>"; return "<html>" + head + "<body>" + bodyHTML + "</body></html>";}End
最后，原本还担心如何控制WebView的高度，没想到WebView可以自己适应内容最长的高度。再附上别人总结的WebView常见问题
