Question

我有一些html标签的数据，我想在webView中显示它。

我尝试了以下代码：

String html = "<html><body><font face=\"verdana\" size=\""
                + getResources().getString(R.string.WebView_Font_Size)
                + "\" color=\"rgb(64,64,64)\">"
                + Article.getDetaildescription().replaceAll("h2", "h4")
                + "</font></body></html>";
String mime = "text/html";
String encoding = "utf-8";
Log.e("htmlstring", html);
description.loadDataWithBaseURL(null, html, mime, encoding, null);

问题是：无论何时执行上述代码，webview中都不会加载任何内容。但是一旦我锁定设备＆amp;解锁它，我的webview显示该数据。

Answer 1

您的代码似乎没问题。检查你的xml文件它可能会帮助你..我想知道你是否动态设置任何布局或其他东西的可见性..

Answer 2

尝试

 wv.loadDataWithBaseURL(null,html,"text/html","utf-8","about:blank");

Answer 3

您可能需要在加载数据之前启用javascript。

String strWeb = "<div style=\"text-align: center;\"><span class=\"Apple-style-span\" style=\"font-weight: normal; font-size: medium; \"><img src=\"http://mobileecommerce.site247365.com/admin/assetmanager/images/gns_header.jpg\" alt=\"\" align=\"middle\" border=\"1px\" height=\"90\" width=\"550\"></span></div><span class=\"Apple-style-span\" style=\"color: rgb(105, 105, 105); font-family: Verdana; font-size: 13px; font-weight: normal; \"><br><div style=\"text-align: center;\">Yes we are coming at E & I?

Answer 4

从jaimin回答我得到了暗示。

我的旧布局文件在其他线性布局中包含一个线性布局，因此我更改了webview的高度以包装内容，同时更改滚动视图的宽度以填充父级＆amp;删除一个不必要的LinearLayout。

旧问题布局

<include
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    layout="@layout/header_layout" />

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/title_background"
    android:padding="5dp" >

    <Button
        android:id="@+id/Article_Detail_Share"

                android:textColor="@color/text_header_red"
                android:textSize="@dimen/s20sp" />

            <TextView

            android:layout_height="0dp"
            android:layout_margin="3dp"

    </LinearLayout>
</ScrollView>

<include
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"

更新了布局文件

    layout="@layout/header_layout" />

我知道有webview＆amp;滚动视图中的库是不是很好的方法，但它的项目要求。

数据未在WebView中加载，但在锁定后加载 - 解锁设备
