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

我想在显示图像和 TextView 的 WebView 中显示 HTML，但我的代码只显示文本但不显示图像。

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":

要加载图像，您需要使用loadDataWithBaseURL. 要使用视图数据加载图像，请参阅此链接。

得到你的 JSON 字符串后：

String content = HttpApi.getContent(URL);

您将传递以前的 URL 以在 webview 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
