老套路看圖：

這是通過webview加載HTML源碼顯示的網頁：加載方法如下：

webview.loadDataWithBaseURL(null, htmlData, "text/html", "utf-8", null);

設置滾動條不顯示的方法有兩種：

第一種：在xml中配置scrollbars為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" />

第二種：Java代碼設置

//設置WebView滾動條不顯示//水平不顯示wvReadMsgContent.setHorizontalScrollBarEnabled(false);//垂直不顯示wvReadMsgContent.setVerticalScrollBarEnabled(false);

?設置webview自適應的方法：

//設置網頁自適應wvReadMsgContent.getSettings().setUseWideViewPort(true);wvReadMsgContent.getSettings().setLoadWithOverviewMode(true);

設置webview支持手勢縮放功能

// 設置可以支持縮放wvReadMsgContent.getSettings().setSupportZoom(true);// 設置出現縮放工具wvReadMsgContent.getSettings().setBuiltInZoomControls(true);

設置后再看下效果：

WebView已自適應,WebView滾動條也隱藏了HTML數據也加載出來了

如果看著復雜我貼下完整代碼：xml（缺少的資源文件請自行補全）

activity_read_message.xml
