我正在使用此代码突出显示文本
origString = origString.replaceAll(textToHighlight,"<font color='red'>"+textToHighlight+"</font>");
Textview.setText(Html.fromHtml(origString));
此代码以区分大小写的方式更改颜色，但不会更改不区分大小写的颜色！
我怎样才能做到这一点？
提前致谢 ！

这是我的代码，显示对话框中的文本
listview1.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view, int position, long id){

要不区分大小写地替换文本，您将需要使用(?i)pattern修饰符。
但是，有一个小警告：在您的示例中hello，aaaHELLOaaa将替换为会导致：
aaa<font color='red'>hello</font>aaa
那是因为您不区分大小写地进行搜索，但是却敏感地进行了替换。
为了克服这个问题，您应该将文本替换为找到的确切结果：
replaceAll("(?i)("+textToHighlight+")", "<font color='red'>$1</font>");
作为一个旁注：请确保您从[textToHighlight所有括号。
