WebView實現說明：

1.通過findViewById獲取WebView。

webview = (WebView) view.findViewById(R.id.content);

2.設置webView的默認編碼方式。

webview.getSettings().setDefaultTextEncodingName("utf-8");

3.調用loadDataWithBaseURL方法加載數據。（loadData會出現亂碼）

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

4.在佈局文件中定義

<WebView
    android:id="@+id/content"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:background="@null"
    android:padding="0dp" />

查找很久沒有發現這個問題如何解決，還是換一種實現方法（使用TextView來替換WebView）

content = (TextView) view.findViewById(R.id.content);
...
content.setText(Html.fromHtml(data.getContent()));
