java - 如何在 java/android 中更改字符串中特定字符的颜色？

Question

我有一个字符串。

String text= //Some String That I know
String textToBeColored = //Some Letter User enters at run time

如何更改用户在运行时在我的字符串中输入的特定字母的颜色。

Answer 1

我假设您希望在字符串中突出显示用户选择的特定文本之类的内容。下面应该可以帮助您做到这一点。

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);
