Android 自定义带拼音Textview 带音调

1. 拼音textview，简单的为把拼音数组和汉字数组结合在一起多行显示

2. 汉字转拼音使用 implementation ‘com.belerweb:pinyin4j:2.5.0’

   public static String[] getPinyinString(String character) {
       if (character != null && character.length() > 0) {
           String[] pinyin = new String[character.length()];
           HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
           format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
           format.setToneType(HanyuPinyinToneType.WITH_TONE_MARK);
           format.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);
           for (int index = 0; index < character.length(); index++) {
               char c = character.charAt(index);
               try {
                   String[] pinyinUnit = PinyinHelper.toHanyuPinyinStringArray(c, format);
                   if (pinyinUnit == null) {
                       pinyin[index] = "  ";
                   } else {
                       pinyin[index] = pinyinUnit[0];
                   }
               } catch (BadHanyuPinyinOutputFormatCombination badHanyuPinyinOutputFormatCombination) {
                   badHanyuPinyinOutputFormatCombination.printStackTrace();
               }
   
           }
           return pinyin;
       } else {
           return null;
       }
   }
