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

import android.annotation.SuppressLint;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.text.TextPaint;import android.util.AttributeSet;import android.widget.TextView;import com.cgtn.chineselearning.utils.ChineseCharacter2Spell;import com.cgtn.common.utils.ConvertUtils;@SuppressLint("AppCompatCustomView")public class SpellTextView extends TextView {  private String[] pinyin;  private String[] chinese;  private TextPaint textPaintSpell = new TextPaint(Paint.ANTI_ALIAS_FLAG);  private TextPaint textPaintChinese = new TextPaint(Paint.ANTI_ALIAS_FLAG);  private int fontSizeSpell = ConvertUtils.dp2px(12);  private int fontSizeChinese = ConvertUtils.dp2px(12);  private int colorSpell = Color.parseColor("#1b97d6");  private int colorChinese = Color.parseColor("#000000");  public SpellTextView(Context context) {    super(context);  }  public SpellTextView(Context context, AttributeSet attrs) {    super(context, attrs);  }  public SpellTextView(Context context, AttributeSet attrs, int defStyleAttr) {    super(context, attrs, defStyleAttr);    initTextPaint();  }  public void initTextPaint() {    float denity = getResources().getDisplayMetrics().density;    textPaintSpell.setStrokeWidth(denity);    textPaintChinese.setStrokeWidth(denity);    textPaintSpell.setTextAlign(Paint.Align.LEFT);    textPaintChinese.setTextAlign(Paint.Align.LEFT);    //设置字体大小    textPaintSpell.setTextSize(fontSizeSpell);    textPaintChinese.setTextSize(fontSizeChinese);    textPaintSpell.setColor(colorSpell);    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++) {        pinyinWidth = widthMesure + textPaintSpell.measureText(pinyin[index]);        if (pinyinWidth > getWidth()) {          comlum++;          widthMesure = 0;        }        canvas.drawText(pinyin[index], widthMesure, (comlum * 2 - 1) * (textPaintChinese.getFontSpacing()), textPaintSpell);        canvas.drawText(chinese[index],            widthMesure + (textPaintSpell.measureText(pinyin[index]) - textPaintChinese.measureText(chinese[index])) / 2,            (comlum * 2) * (textPaintChinese.getFontSpacing()), textPaintChinese);        if (index + 1 < pinyin.length) {          widthMesure = widthMesure + textPaintSpell.measureText(pinyin[index] + 1);        } else {          widthMesure = widthMesure + textPaintSpell.measureText(pinyin[index]);        }      }    }  }  //拼音和汉字的资源  public void setSpellAndChinese(String[] pinYin, String[] chinese) {    this.pinyin = pinYin;    this.chinese = chinese;  }  //设置文字资源  public void setStringResource(String string) {    initTextPaint();    String[] spellArray = ChineseCharacter2Spell.getPinyinString(string);    StringBuilder stringBuilder = new StringBuilder();    for (String s : spellArray){      stringBuilder.append(s);      stringBuilder.append(" ");    }    char[] chars = string.toCharArray();    String[] chineseArray = new String[chars.length];    for (int i = 0; i < chars.length;i++){      chineseArray[i] = String.valueOf(chars[i]);    }    setSpellAndChinese(spellArray,chineseArray);  }  //设置文字颜色  public void setStringColor(int spellColor,int chineseColor) {    textPaintSpell.setColor(spellColor);    textPaintChinese.setColor(chineseColor);  }  //设置文字大小  public void setFontSize(float spellFontSize,float chineseFontSize) {    textPaintSpell.setTextSize(ConvertUtils.dp2px(spellFontSize));    textPaintChinese.setTextSize(ConvertUtils.dp2px(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;  }}
