老套路看图：
这是通过webview加载HTML源码显示的网页：加载方法如下：
webview.loadDataWithBaseURL(null, htmlData, "text/html", "utf-8", null);
设置滚动条不显示的方法有两种：
第一种：在xml中配置scrollbars为none即可
<WebViewandroid:id="@+id/wv_read_msg_content"android:layout_width="match_parent"android:layout_height="300dp"android:layout_marginBottom="10dp"android:scrollbars="none" />
第二种：Java代码设置
//设置WebView滚动条不显示//水平不显示wvReadMsgContent.setHorizontalScrollBarEnabled(false);//垂直不显示wvReadMsgContent.setVerticalScrollBarEnabled(false);
设置webview自适应的方法：
//设置网页自适应wvReadMsgContent.getSettings().setUseWideViewPort(true);wvReadMsgContent.getSettings().setLoadWithOverviewMode(true);
设置webview支持手势缩放功能
// 设置可以支持缩放wvReadMsgContent.getSettings().setSupportZoom(true);// 设置出现缩放工具wvReadMsgContent.getSettings().setBuiltInZoomControls(true);
设置后再看下效果：
WebView已自适应,WebView滚动条也隐藏了HTML数据也加载出来了
如果看着复杂我贴下完整代码：xml（缺少的资源文件请自行补全）
activity_read_message.xml
