TextView 中的 Roboto 灯和 Roboto 粗体

Question

我可以像这样在 Android 2.3 上的同一个 TextView 中应用 Roboto light 和 Roboto bold 吗？

**user** has been publish a beez

**user** 是 Roboto 粗体，has been publish a beez 是 Roboto 浅色

Answer 1

是的，你可以这样做..

String firstWord = "user";
String secondWord = "has been publish a beez";

// Create a new spannable with the two strings
Spannable spannable = new SpannableString(firstWord+secondWord);

// Set the custom typeface to span over a section of the spannable object
spannable.setSpan( new CustomTypefaceSpan("sans-serif",CUSTOM_TYPEFACE), 0, firstWord.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
spannable.setSpan( new CustomTypefaceSpan("sans-serif-light",SECOND_CUSTOM_TYPEFACE), firstWord.length(), firstWord.length() + secondWord.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

// Set the text of a textView with the spannable object
textView.setText( spannable );

您可以像这样从 Android 4.1+ 原生使用 Roboto：

android:fontFamily="sans-serif"           // roboto regular
android:fontFamily="sans-serif-light"     // roboto light
android:fontFamily="sans-serif-condensed"
