如何在我的String中更改用户在运行时输入的特定字母的颜色.

Answer 1

我假设你想要用户选择在字符串中突出显示的特定文本.下面应该可以帮到你.

String text = "abcada";
String textToBeColored = "a";

String htmlText = text.replace(textToBeColored,"<font color='#c5c5c5'>"+textToBeColored +"</font>");
// Only letter a would be displayed in a different color.
txtView.setText(Html.fromHtml(htmlText);
