The problem lies with "\\r\\n" in your json data. 问题在于您的json数据中存在“ \\ r \\ n”。 Look like \\r\\n work only if they are wrapped in tag. 看起来\\ r \\ n仅在将它们包装在标签中时才起作用。 Easy solution would be replace \\r\\n with 简单的解决方案是将\\ r \\ n替换为
tag. 标签。
String all="<html><body>"+newsContent.replace("\\r\\n", "<br/>")+"</body></html>";

String text = "<html><body style=\"text-align:justify\"> %s </body></Html>";
String data = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas ac quam risus, at tempus justo. Sed dictum rutrum massa eu volutpat. Quisque vitae hendrerit sem.";
WebView webView = (WebView) findViewById(R.id.WebView);
webView.loadData(String.format(text, data), "text/html", "utf-8");

Below works. 下面的作品。 There should be double slash \\r\\n 应该有双斜杠\\ r \\ n
String all=""+newsContent.replace("\\r\\n", "
")+"";
