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

@SuppressLint("AppCompatCustomView")
public class SpellTextView extends TextView {

private TextPaint textPaintSpell = new TextPaint(Paint.ANTI_ALIAS_FLAG);
private TextPaint textPaintChinese = new TextPaint(Paint.ANTI_ALIAS_FLAG);
private int fontSizeSpell = ConvertUtils.dp2px(12);

textPaintChinese.setStrokeWidth(denity);

//设置字体大小
textPaintSpell.setTextSize(fontSizeSpell);

textPaintChinese.setColor(colorChinese);
}
@Override
protected void onDraw(Canvas canvas) {
float widthMesure = 0f;
int comlum = 1;
float pinyinWidth;
if (pinyin != null && pinyin.length > 0) {
for (int index = 0; index < pinyin.length; index++) {

}

//拼音和汉字的资源

}
//设置文字资源

public void setFontSize(float spellFontSize,float chineseFontSize) {

}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;
}
