本文实例为大家分享了Android自定义带拼音音调Textview的具体代码，供大家参考，具体内容如下

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;

}

}
