Question

我在新闻应用程序上工作我的json响应是html格式，因为它有多种颜色。我需要在单个文本视图中显示此文本。我的回答是这样的，

我的代码就像这样

fastionDesc=(TextView) v.findViewById(R.id.desc_desc);
String fidscription=newsobj.getString("articledec");
String parts[]=fidscription.toString().split("color");
for(int i=0;i<parts.length;i++) {
    if(i==1) {
        fidscription = fidscription.replaceAll(parts[i], "<font color='#000099'>" + parts[i] + "</font>");
    }
    if(i!=1&&i/2==0) {
        fidscription = fidscription.replaceAll(parts[i], "<font color='#000000'>" + parts[i] + "</font>");
    }
    if(i!=1&&i/2==1) {
        fidscription = fidscription.replaceAll(parts[i], "<font color='#ff0066'>" + parts[i] + "</font>");
    }
}
fastionDesc.setText((Html.fromHtml(fidscription)));
fastionDesc.setTypeface(tf);

当我这样做时，我收到了错误

请帮助。

Answer 1

似乎html有一些错误，或者Html.fromHtml（）不支持它。

尝试在webview上加载

WebView webview = new Webview(this);
webview.loadHtml(fidscription);

希望这有帮助。

Answer 2

您的错误是因为replaceAll正在使用parts[i]作为正则表达式，而其中的某些内容存在无效的正则表达式。请改用replace。这应该会让你超过你发布的错误。
