Question

我在JSON中获取包含图像的HTML标记。当我在WebView中加载时没有显示任何图像，为什么？

我想在WebView中显示HTML，它显示图像和TextView，但我的代码只显示文本但没有图像。

知道为什么吗？

WebView      wv = (WebView) findViewById(R.id.webview1);


   String   htmldescription = school2.getJSONObject(0).getString("description");

wv.loadData(htmldescription, "text/html", "utf8");

              {"Status":1,
          "data":

Answer 1

要加载图片，您需要使用loadDataWithBaseURL。要使用视图数据加载图片，请参阅this链接。

Answer 2

获取JSON字符串后

：

String content = HttpApi.getContent(URL);

您将传递以前的网址以在网络视图中加载数据

webview.loadDataWithBaseURL(URL, contentAfterParsing, "text/html", "UTF-8", null);

之后您将在webview中看到图像

im html只显示文字但没有图片。
