you have to set the Color of the Text in TextView. Not the String color. It is not valid.
您必须在 TextView 中设置文本的颜色。不是字符串颜色。它无效。
textView.setTextColor(Color.RED);
or Change your String to Html like this,
或像这样将您的字符串更改为 Html，
String s= "<font color=#00aeef>"+"Right Answers:" + " " + String.valueOf(nRightAnswers)+"</font>";
and
和
textView.setText(Html.fromHtml(s));
And find the color code for red and replace it with, color=#00aeeffor the color you want, say red.
并找到红色的颜色代码并将其替换color=#00aeef为您想要的颜色，例如红色。

Create file res/drawable/text_color.xml:
创建文件 res/drawable/text_color.xml：
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:state_pressed="false" android:color="#ffffff" />
<item android:state_focused="true" android:state_pressed="true" android:color="#ffffff" />
<item android:state_focused="false" android:state_pressed="true" android:color="#ffffff" />
<item android:color="#000000" />
</selector>
Then use @drawable/text_color from xml (or R.drawable.text_color from code) as text color for your list view items.
然后使用 xml 中的 @drawable/text_color（或代码中的 R.drawable.text_color）作为列表视图项的文本颜色。
