我是android的新手，我正在从上述json检索数据并将其显示在列表中。一切正常，但如果我检索到数据，它也会显示html标签。请澄清我的疑问，如何在列表视图中显示时从json中删除html标签。

Answer 1

您可以使用正则表达式将其删除-

public class xlWatermark {
    public static void main(String[] args) {
        HSSFWorkbook wb = new HSSFWorkbook();
        FileOutputStream fileOut = null;
        try {
            fileOut = new FileOutputStream("Test.xls");
            HSSFSheet ws = wb.createSheet("testSheet");
            HSSFPatriarch dp = ws.createDrawingPatriarch();
            HSSFClientAnchor anchor = new HSSFClientAnchor
                (0, 0, 1023, 255, (short) 2, 4, (short) 13, 26);
            HSSFTextbox txtbox = dp.createTextbox(anchor);
            HSSFRichTextString rtxt = new HSSFRichTextString("test");
            HSSFFont font = wb.createFont();
            font.setColor((short) 27);
            font.setBoldweight(HSSFFont.BOLDWEIGHT_NORMAL);
            font.setFontHeightInPoints((short) 192);
            font.setFontName("Verdana");
            rtxt.applyFont(font);
            txtbox.setString(rtxt);
            txtbox.setLineStyle(HSSFShape.LINESTYLE_NONE);
            txtbox.setNoFill(true);
            wb.write(fileOut);
            fileOut.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } 
    }

完整的代码示例为-

var myString = '[{"id":1,"header":"<tr><td style=\"width:5.36%\" width=\"5%\">Test</td>"}]';
var newString = myString.replace(/<(?:.|\n)*?>/gm, '');

希望这对您有所帮助。

Answer 2

myHtmlString.replaceAll（“ s /<(.*?)>// g”，“”）; Html.fromHtml（htmlSrc）.toString（）;

Answer 3

这是一种不好的方法...您必须通过json validate来验证json响应。

尝试更改来自后端的响应... 甚至您也可以通过在Java中将字符串替换为null来替换[“，;，/ ... etc] ...

html = html.replaceAll（“ <（。？）\>”，“”）; //删除其中的所有项目括号 html = html.replaceAll（“ <（。？）\\ n”，“”）; //必须在下面 html = html.replaceFirst（“（。*？）\>”，“”）; //将所有连接的项目移至最后一个括号 html = html.replaceAll（“”，“”）; html = html.replaceAll（“＆”，“”）;

如何从json删除html标签？
